JVC DLA NZ7 frontrightangle

The evolution of JVC's highly regarded LCoS-based D-ILA projectors has been nothing if not slow and steady. The company was late to the 4K party, at least compared to their LCoS rival Sony, and relied for several years on 1080p imagers combined with their e-shift pixel-shifting technology before launching their first consumer native 4K projectors in 2018. Those lamp-based projectors, including the DLA-NX5/RS1000, DLA-NX7/RS2000, and DLA-NX9/RS3000 have been exceptionally well received by reviewers and enthusiasts, and have undergone some significant updates that added value for new users and existing owners. When the line was introduced, JVC became the first manufacturer to add Auto HDR functions that read the static metadata in HDR10 programs to optimize the image, but this later gave way to an even more successful "Frame Adapt" dynamic HDR tone-mapping scheme. Then, with another update last November, the company added Theater Optimizer, which further enhanced the projectors' performance with customization based on the individual user's installation details, such as their screen size and material and lamp usage. What's been missing from JVC's line, except for a single high-end prosumer model, has been laser projectors that need no lamp replacements.

That will change this fall following JVC's announcement of a new line-up of laser projectors that not only bring the usual benefits of a solid-state light engine but also a number of key advancements that can't be boasted even by Sony's recently updated models. Furthermore, JVC's pricing of its laser projectors is notably aggressive next to Sony's.

Features

As reported earlier, the new JVC consumer line-up will consist of three new laser models plus the existing lamp-based, entry-level DLA-NX5/RS1000 at $5,999. The new flagship, at $24,999, is the DLA-NZ9/RS4100 (with the RS Reference Series designation used for the integrator channel per JVC's usual approach). It's a 3,000 lumen projector that, like the other new laser models, uses JVC's third-generation BLU-Escent module with a blue laser diode array and yellow phosphor wheel to generate the red, green, and blue signals for the native 4K, 0.69-inch D-ILA imagers. The projectors are rated at 20,000 hours to half-brightness, and also enjoy the usual laser advantage of rapid start-up and shut down. On my DLA-NZ7 sample I timed 32 seconds to seeing the D-ILA logo on screen and about 40 seconds to a picture from a live source. The projector goes dark immediately upon shut down and typically runs the fan for about 10 seconds more.

As with previous JVC line-ups, the top model has the largest lens (a 100mm, 18 element/16 group in this case), hand-picked components, and the highest rated contrast ratio, which is 100,000:1 native and "infinite" dynamic. Of course, "infinite" is a term used here to describe a state in which the projector receives a black signal and fully shuts down its laser, but the actual lowest possible contrast with any signal above black will be based on some minimum idle brightness.

JVC DLA NZ7 top

The step down models are the DLA-NZ8/RS3100 at $14,999 (2,500 lumens, 80,000:1 native/infinite dynamic contrast), and the subject of our review, the DLA-NZ7/RS2100, which will go for $9,999 upon its expected release at the end of October. It puts out 2,200 lumens and offers 40,000:1 native/infinite dynamic contrast. By comparison, Sony's least-expensive laser model, the VPL-VW915ES, costs twice as much.

Notably, besides an advantage on price, these JVC's leapfrog the competition in two key areas. To begin, all the new models have full 48 Gbps bandwidth HDMI 2.1/HDCP 2.3 ports, which makes them the first projectors we've seen that are fully compatible with 4K/120 Hz signals from the latest gaming consoles, not to mention future-looking for even higher resolution signals up to 8K/60 Hz. Gaming is further supported by the same Low Latency Mode feature that has appeared in prior JVC models. On the NZ7, I measured a low input lag of 36.0 milliseconds with Low Latency engaged on a 1080p/120 Hz signal, or 36.5 ms with 1080p/60 Hz. For sports, action flicks, or other less lag-sensitive viewing, frame interpolation is provided with the Clear Motion Drive feature.

Critically, the top two models (DLA-NZ9 and DLA-NZ8) feature a new version of e-shift dubbed e-shiftX that applies four-phase pixel-shifting running at 240 Hz to the native 4K panels, resulting in another first in a consumer projector: full pixel-count rendering of 8K video with no need to toss any signal information. The step-down NZ7 applies JVC's previous two-phase/120 Hz e-shift to enhance 4K or 8K signals beyond native 4K resolution. This feature, minus the compatibility with 8K signals, was previously reserved for JVC's top-of-the-line DLA-NX9.

8k eshift 800px
The pre-existing two-phase 8K e-shift technology found in the DLA-NX9 is in the new NZ7. A more advanced four-phase 8K e-shiftX technology that operates at 240 Hz is found in the DLA-NZ9 and DLA-NZ8.

Beyond the new laser engine, the updated HDMI connectors, and the e-shift, the projectors all carry over JVC's Frame Adapt frame-by-frame or scene-by-scene dynamic tone-mapping and the Theater Optimizer enhancement. Furthermore, they now also offer HDR10+ compatibility along with HDR10 and HLG. Gamut is rated at greater than 100% DCI-P3 with engagement of the internal Cinema Filter in the two top models. For the NZ7, which lacks the Cinema Filter, the company claims only "Wide Color Gamut (DCI Coverage)." You'll find the results of my color volume measurement in the Performance section below. All the new models are ISF-licensed and offer JVC's own Auto Calibration if you add an appropriate color meter to a Windows PC with the company's free downloadable software.

The lens on the NZ7 is a 65mm all-glass affair with 17 elements in 15 groups. As with the larger 100mm lens, it's a carry-over from JVC's existing NX lineup. The wide 2X zoom throws a 100-inch 16:9 image from approximately 11 to 22 feet. (You can see the throw range for your preferred image size with the ProjectorCentral DLA-NZ7 calculator.) It offers generous ±80% vertical/±34% horizontal lens shift, and there are 10 lens memories for use with a constant image height setup for a 2.35:1 'Scope screen. There are also anamorphic aspect modes for an outboard lens.

Cosmetically, all three models are similar to the existing line, with a fairly large chassis and a design that brings in cool air from the back and expels it from a pair of vents that straddle the lens. The DLA-NZ7 measures 19.7 x 9.2 x 19.9 inches (WHD) and weighs 49.5 pounds. It accommodates shelf- or inverted ceiling mounting for either front or rear projection. One of the benefits of a large chassis and lack of a lamp here is exceptionally low fan noise. The NZ7 is rated for 24 dBA in Low laser mode using the standard averaged factory lab measurement in a soundproof chamber. I took casual measurements from five feet in front of and two feet below it, which mimics a close ceiling mount and in this case also happens to be exposed to the exhaust fans. In a room with a 27 dBA noise floor, the fan noise with the LD Power laser setting in its Low or Mid position was a quiet hush that measured 37.1 dBA. It climbed to a slightly louder 38.6 dBA in the High position, which also offered a slightly higher pitch to the sound, but it was still easily masked by most soundtracks. And unlike a number of other laser projectors I've tested, there was no high-pitched electronic whine associated with the Blu-ESCENT engine. This is a quiet projector that can live near its viewers.

JVC DLA NZ7 remote

The jackpack is on the rear panel along with a second IR receiver and a keypad you can use in place of the remote. Beyond the pair of modern-day HDMI ports, you get a few control connections: RS-232C, RJ45 LAN, and a 12v trigger output. A USB Type A port is strictly for firmware updates; it won't play content from a flash drive. There's also a 3-pin Mini-DIN 3D sync output for one of JVC's RF 3D emitters, such as the PKEM2 ($99). An emitter and compatible glasses are required for Full 3D playback.

The remote control is the same compact, 7-inch wand JVC introduced when it launched its 4K lamp models. It has bright backlit legends on the buttons, but doesn't have as much direct access to picture adjustments as JVC's older full-size remotes, and the flat buttons are all adjoining so they can't really be discerned by feel. Still, most of what a tweaker will want is there, including buttons to change the Picture Mode, Color Profile, and Gamma Settings, plus the lens controls and memories. For most of my evaluation I used the full-featured remote from my JVC DLA-X790, which worked perfectly and made life easier.

Performance

Those familiar with JVC's current line-up will recognize the organization and most attributes of the prior menu system. To begin, there's a helpful control that allows you to set the projector to go into the picture mode of your choice when it recognizes a given signal type, whether SDR, HDR, or 3D. For SDR, there are just two picture modes, Natural and Cinema, plus some customizable User modes that start out mimicking the Natural mode. You can engage one of 7 preset color temperatures, tune the grayscale with 2-point RGB Gain and Bias controls, or adjust the color space with the RGBCMY Color Management controls. The gamma settings are extensive, and include a wide range of presets as well as the ability to create your own customized setting with separate controls to independently adjust the brightness of the overall image (Picture Tone), the Dark Level, or the Bright Level, for either White or any of the three primary colors.

For SDR, neither of the two available presets on our sample looked great out of the box, even after I performed a firmware update during the course of my evaluation that addressed some other image quality issues I'll discuss later. Natural mode, which has traditionally been JVC's tuning for a classic Rec.709/D65/2.2 gamma target, offered subjectively balanced color but exhibited a noticeably warm red cast in whites and skin tones, and was too bright and washed out for my 92-inch 1.3 gain matte white screen before making any adjustments to tone down the light. The Cinema mode was more accurate out of the box to its already warm 5500K default color temperature. I found that setting the projector to its 7500K color temperature subjectively gave it the most neutral whites, and without imposing any excess blue tint that the label implies. Sure enough, I confirmed later that this setting measured fairly close to a dialed-in 6500K white point.

I'll cut JVC some slack here—we're talking about an early production sample of a brand new laser projector family. Given the company's history of excellence in years past, it won't surprise me to find that things are even more fine-tuned over time, perhaps even before models reach the market at the end of October. JVC says these projectors will remain a work in progress until their official release date. Still, absent of any additional updates, your best bet for an accurate SDR image short of full calibration is to call up the Natural mode and make the simple change from 6500K to 7500K color temperature in the menu. With the latest firmware revision as of this review (v0.92), this resulted in a fairly accurate grayscale and nearly spot-on color points. I also set the Gamma to 2.4 instead of the default 2.2 to better suit my dark room environment and take greater advantage of the NZ7's excellent contrast.

Of course, anyone spending $10K or upwards for a projector should plan on investing in professional calibration. Eventually, I did just that, calibrating the Natural mode for an accurate D65 grayscale, 2.4 gamma, and Rec.709 gamut. Measurements with Portrait Displays' Calman Ultimate color calibration software, a Murideo Six-G generator, and an X-Rite i1Pro2 photospectrometer showed that the default 6500K Natural and User mode white point was sitting above and off-hue the D65 target, slightly oversaturated and straddling the line between green and red on a CIE color chart. It measured 5340K at 100% white, which explained the too-warm cast.

Fortunately, the DLA-NZ7 calibrated beautifully for grayscale, and also tuned up well for the color points that define the color space, demonstrating generally excellent tracking across the less-bright saturation points between 20% and 80%. The post-calibration grayscale errors were 2.4dE or under from 10% to 100% brightness, while the color point errors were nearly all at or below 2.0dE. This is excellent performance, and it showed up on the screen. (dE or Delta E describes the accuracy of a display's grays or colors. A dE under 3—some say under 4—is considered indistinguishable from a perfect result.)

The default when the projector sees an HDR10 signal is its HDR10 picture mode, which has its own HDR10 color temperature setting that also targets the neutral industry standard D65 (6500K) white point. As with SDR, this can be tuned with RGB Gain and Bias settings. You have a choice in the basic HDR10 picture mode of two Tone-Mapping options, an Auto setting that reads the metadata on HDR discs for a coarse tone-map adjustment but makes no attempt at dynamic tone-mapping, though it allows some tuning with a 11-step Mapping Level slider (-5 to +5). It defaults to a BT.2020 color space. (Other color space options include BT.709 and DCI.) You can use the Color Management system to tune the color points for the primaries and secondaries as you can with SDR. If you set the Tone-Mapping option in the HDR10 picture mode to HDR(PQ), you're flying solo and adjusting the tone-map manually. As with previous JVC projectors, you can select White, Red, Green, or Blue and adust overall Picture Tone, Dark Level, and Bright Level for each.

JVC DLA NZ7 front

The other HDR picture mode options include Frame Adapt or Pana_PQ. The latter was introduced in earlier projectors to provide a baseline for the outboard tone-mapping solution in Panasonic's UB series UHD Blu-ray players. As with SDR, there are also three user-definable Custom modes. Frame Adapt HDR, JVC's dynamic tone-mapping system, is obviously of greatest interest here for its ability to optimize images on the fly on either a scene-by-scene or more aggressive frame-by-frame analysis. The beauty is not having to worry about making adjustments to account for the wide range of mastering on HDR titles.

For any mode, including the SDR modes, you can opt to use or leave off the Dynamic Control setting, or "Dynamic CTRL" in the menu. The NZ9 and NZ8 each have two apertures, one in the lens and one in the light path, while the NZ7 has just the one in the lens. But according to JVC, these are not dynamic and can only be adjusted manually during setup to match your environment or on the fly to accommodate darker content. However, all three models do modulate the laser as needed in much the way the company's lamp projectors relied on a dynamic aperture to assist with black level on dark content. The Dynamic Control offers two settings besides off, Mode 1 and Mode 2. They work in a manner somewhat similar to the Auto 1 and Auto 2 iris settings in JVC's lamp models, with Mode 2 providing the finest degree of control and the most aggressive action when it encounters brightness changes in the content. Mode 1, by comparison, works less fast and is more subtle. I'll say more about this feature below, but happily my initial concerns with its performance were addressed in the firmware update I received, and JVC says it's likely to be further improved before the projector's release.

The default for the three-position LD Power laser setting in the HDR picture modes is High, though I got a noticeable improvement in overall contrast with the Mid setting on my screen at its relatively small size and 1.3 gain. This change added some depth to the black while still providing enough range on the Contrast control to punch up the peak white to meet my somewhat aggressive tastes for highlights. Although the 6500K color temperature setting in HDR suffered the same too-warm cast I saw in the SDR modes, changing it again to the 7500K setting helped get it closer—still a touch red, but within spitting distance. Before any other calibration beyond these tweaks, the Frame Adapt mode with the dynamic Frame by Frame tone-mapping option and 7500K color temp setting offered a highly watchable picture with nice punchy highlights and solid blacks.

JVC DLA NZ7 BLU Escent
JVC's BLU-Escent light engine uses the blue laser-diode module shown here and a yellow phosphor wheel to achieve all the primary colors.

Eventually, I temporarily put the Frame Adapt mode into its Static tone-mapping setting for calibration and evened out the RGB balance on the grayscale. I performed only modest changes to the color points to get them a bit closer to the 50% BT.2020 saturation points typically used by the Calman software to calibrate HDR TVs. This was where the DLA-NZ7 showed its color gamut limitations. Keep in mind this is the only projector among the three new laser models that lacks a Cinema Filter to achieve full DCI-P3. Green in particular couldn't reach out far enough, and post calibration the projector showed some unevenness in DCI-P3 saturation sweeps inside of BT.2020. Color volume measurements, taken in either the Frame Adapt or HDR10 picture modes, showed that the NZ7's color gamut reached 82.6% DCI-P3, 55.8% BT.2020, and 123.4% Rec.709. Still, whether we're talking about pre-cal or post-cal settings, color accuracy for HDR was mostly excellent and just a touch below the dead-on performance of the tuned-up Natural mode, albeit with obviously better dynamic range and wider gamut. Post calibration, I usually watched HDR in the Frame Adapt mode with the Frame by Frame tone-mapping option.

As a final note on calibration and settings, I should comment on the Dynamic CTRL setting for the laser that's intended to mimic a dynamic iris. Prior to the mid-review firmware update JVC sent I had resigned myself to not using this feature. It often had the effect of reducing overall contrast whenever it was active in either its Mode 1 or Mode 2 setting, for either SDR or HDR. It would typically make the image either slightly brighter or darker depending on the content, but always it seemed to be to the detriment of dimensionality. To make matters worse, whenever any menu was called up, the image behind it would temporarily revert (to what it looks like with the Dynamic CTRL set to off). That made it impossible to make additional image adjustments when this feature was active since exiting the menu resulted in the image noticeably shifting again—though for a moment it functioned for a rough A/B comparison until the menu came up. Admittedly, this kind of shifting also takes place to some extent with my DLA-X790 lamp projector on some dark scenes if you call up a menu when the automatic aperture is engaged. But it is never as dramatic and annoying as I saw with the NZ7. Perhaps it's because in the X790 that feature controls a mechanical iris while the Dynamic CTRL in the NZ7 is actually manipulating the light source along with its signal processing.

The new firmware didn't affect the latter issue with the menu interaction, which is primarily obvious on dark scenes. But more critically, after the update the worst detrimental effects of the Dynamic CTRL on overall contrast were gone and it became a more useful tool for darker movies or those with a lot of scenes with low average picture level. Post update, engaging the control offered a more straightforward trade-off of some peak brightness in exchange for a darker black. For example, shots of starfields and the expanse of space in the various sci-fi flicks I watched benefited from the deepened black at the expense of some sparkle on the stars. Nonetheless, use of this feature is definitely discretionary.

SDR Viewing. 1080p SDR images were just stunning on the NZ7. The opening sequence from the Blu-ray of Gravity, with its many views of dark space and mixed images with bright highlights (white space suits and white and foil-covered spacecraft) really showed off what great black level can do. To begin, the calibrated whites were bright, crisp and exceptionally neutral—it was impossible to detect even a slight bit of unnatural pink warmth or excess cool blue in them. Even the bouncing white Oppo logo against a black frame from my disc player's screen saver just looked...white.

Gravity presented excellent material to play with the projector's laser Dynamic Control and proved effective here. Mode 1 noticeably deepened an already excellent black level and added dimensionality to the black of space and the letterbox bars, with only a barely detectable sacrifice in brightness. By comparison, Mode 2 tamped down the peak whites more noticeably, while also being more prone to obvious pumping artifacts and severely reduced brightness on demanding content like the white-letters-on-black-background title cards that start this movie. Mode 1 got through those with only the barest hiccup on the third and last title card, though it did noticeably take down the brightness of the letters. I saw the real payoff on a shot that shows the diminishing outline of an astronaut in a white suit tumbling into the distance of a dark starfield. Engaging Mode 1 provided the best compromise by taking down the black of space while retaining just enough pop of the sun's reflections off the space suit and brightness in the stars. Mode 2 delivered a seductively attractive deep black but pulled too much punch from the highlights.

I checked all my go-to scenes from the very colorful La La Land, and the NZ7 aced them all. The subtly varied skin tones among the female protagonist Mia (Emma Stone) and her two roommates sitting beside her on a bed were well delineated, as was Mia's fair skin against the more ruddy complexion of her love interest Seb (Ryan Gosling) while the two walk around a movie studio lot. The highly saturated and often repeated red, green, blue and yellow colors that comprise this film's Oscar-winning set design were all punchy eye candy, and in one shot where Mia lies back on some deep red pillows, I looked for but saw no hint of laser speckle, which can be apparent with some laser projectors in red and magenta objects. Although speckle typically exists to some degree in all laser projectors and is affected by the screen material, it was virtually undetectable with this projector, even with my face near the screen looking into color bars and full-screen patterns that best reveal it.

Post calibration, overall dark movies also displayed well and never once suffered from any noticeable haze, thanks again to the deep native blacks of the D-ILA imaging chips. A shot in The Revenant of a Native American boy sleeping against a tree trunk in the dark woods revealed all manner of detail in the bark, in the shadowed side of his face and dark hair that was outside of the moon's illumination, and in his barely lit clothing. Nature scenes throughout the movie rang true; I observed accurate-looking foliage and rock canyon walls, and seeing the sky and morning sun coming up over a river next to a brown prairie made me want to walk into the scene.

Scaling of good 1080p Blu-rays was clean and noise-free. I experimented with the 8K e-shift on 1080p content and in the vast majority of scenes it provided only the most subtle change from normal viewing distance, even on scenes with a lot of sharp detail. What I could detect with my nose against the screen, or sometimes further back, was most typically a softening of edges on some objects when e-shift was activated. This is not unusual with pixel-shifting, and the results weren't much different later when I moved over to watching 4K; if anything, the feature made the softening more noticeable. The reality is that the pixels from true native 4K LCoS chips, which already enjoy a high fill factor (tight spacing) by design, are pretty much impossible to detect without magnification at normal screen sizes. So the smoothing and blending of pixel edges provided by pixel-shifting really starts offering a diminishing return at higher resolution. There might be a different reality when displaying 8K signals, which I wasn't able to try.

HDR Viewing. I imagine Christopher Nolan's mind-bending Interstellar to be the kind of film Kubrick could have made instead of 2001: A Space Odyssey if he'd done that movie a few decades later. Whatever its strengths or faults as cinema, it's a nice piece of HDR eye candy, particularly the scenes shot in space. Post calibration, the slight rosiness I'd initially detected in the white space suits and the white ship interiors was well neutralized, and skin tones had a more natural look as well, with nice delineation between the fair-skinned Anne Hathaway and the darkly tanned male lead Matthew McConaughey. The pale blue medical scrubs they wore as they got ready to bed down for suspended animation were a familiar color, and exhibited no excess cyan or green. Blacks were deep and highlights punchy. Later, when the crew went through a wormhole, the riot of bright, swirling colors leaped off the screen. In this and most other content I know well I saw excellent color accuracy, though I did notice, for example, that a bright yellow dress worn by Mia in La La Land that was perfect in the 1080p Blu-ray was a bit oversaturated and leaned a touch orange in the HDR version. Perhaps it's something I could have fixed with additional calibration.

First Man, the Neil Armstrong biopic that follows the famed astronaut through the Apollo program, is a challenging HDR transfer with lots of shadowy scenes inside dark spacecraft and dimly lit interiors. Thanks again to the NZ7's deep native blacks and the excellent light management from the Frame Adapt HDR mode, I have rarely seen it look better. Scenes with low average picture level, such as the opening sequence when Armstrong (Ryan Gosling) flies an X-15 rocket plane to the edge of space, dropped the projector's black level to where the black letterbox bars nearly disappeared and allowed it pull all manner of shadow detail from the cockpit. When flashes of bright sunlight poked through clouds or lit up the pilot's face inside his helmet, the projector reacted and the highlights popped while the shadow detail in darker areas remained visible. Never in these shots, nor any inside the dark LEM during the moon landing sequence, did I see any distracting haze due the projector's inability to dig deep enough into black. Shots of the sun-lit lunar landscape with the dark of space above it were absolutely spectacular. There was a deep, inky black above the horizon—one I could make even blacker if I chose to sacrifice some brightness by closing the aperture a bit. But with the calibrated settings the sun's light on the undulating, pockmarked landspace brought out waves of gray and brown and even some blue in the terrain, along with bright punchy white highlights where the sun caught the rock. The depth was absolutely tremendous and mesmerizing.

JVC NZ7 Meg

As I always do with HDR projectors, I pulled out my UHD Blu-ray of The Meg, an action flick in which the enemy is a giant prehistoric shark (as in, better get a much bigger boat). This disc is a 4,000-nit peak HDR transfer with a high average picture level over 1,000 nits that clearly demonstrates how a projector handles bright outlier content. Happily, the DLA-NZ7 handled it with grace after some minor adjustments to take the Brightness control down a few clicks to restore some depth to the black. The dynamic tone-mapping successfully tamped down the sunlight hitting the ocean surface to prevent severe clipping and retain the texture of ripples in the water. Likewise, low-hanging clouds over the ocean horizon had their depth retained.

One very tough-to-display shot in this movie (near the beginning of Chapter 6) is a full length aerial shot of a mostly white research vessel with sunlight striking the water behind it. Some projectors will fully blow out detail on the water behind the vessel and obscure the textured surface, while others will clip the detail in the brightest parts of the boat's hull. With the NZ7 you get to see both as well as a decently dark painted black at the bow-end of the hull. It's impressive dynamic range. In the next chapter, a very bright shot looking up from underwater at a clear Lucite shark cage being lowered into the sea with the sun behind it presents another tough challenge. The NZ7 revealed all the detail in cage structure and the lighting circling its floor and ceiling, while avoiding the banding artifacts that's often seen on this shot in the transition from the bright cage to the darker underside of the boat.

Finally, I threw on some HDR animation just for fun. I'm fond of the scene in The Secret Life of Pets in which Gidget, a puffy white Pomeranian, enters into a full blown mom's-away-from-home party scene in which a neighborhood full of dogs, cats, birds and other pets have taken over the place with all manner of games. The creators worked hard to give objects natural looking color, so things like the green felt of a pool table and the white porcelain of a toilet looked pleasing and familiar. But everything was delivered in ultra-punchy, saturated colors. I couldn't get enough of it.

3D Viewing. JVC sent along a 3D emitter and pair of their glasses so I could check out some 3D. The DLA-NZ7 has an Auto 3D setting that will put up a 3D image when it sees one at the input, but there is no dedicated 3D picture mode and you can set up any of the SDR modes for this purpose. I used one of the SDR User modes for this, which automatically defaulted to my calibrated settings for grayscale and Rec.709 color management. From there, it was a simple matter to boost brightness by taking the LD Power setting for the laser from its default Mid to the High setting. I also set gamma to 2.4, and played with the Contrast, Brightness, and Picture Tone settings to taste for whatever content I was watching. A separate 3D menu provides additional settings to force side-by-side or top-and-bottom format if needed, and separate sliders to tune the parallax and crosstalk cancellation.

The NZ7's brightness provided nice punch with 3D, and I found colors to be essentially true given my calibration for SDR, with only the usual darkening of the image and slight green skew when I put on the glasses. Spiderman: Homecoming demonstrated natural fleshtones, crisp and essentially neutral whites in clothing, and natural looking gray stone and foliage respectively in the Washington Monument and the surrounding grass lawns as Spiderman comes to save the day. Dark scenes were also rendered well, with decent shadow detail.

3D animation was a total blast on the NZ7. A trailer for Madagascar 3: Europe's Most Wanted was incredibly bright, stupendously sharp, and very colorful. I saw only some modest motion artifacts on very quick pans that would challenge any projector, though setting the Clear Motion Drive control helped a bit.

Conclusion

I admit to being a little nervous when I first fired up the laser-driven JVC DLA-NZ7. It exhibits an obvious green cast in the white D-ILA logo that first appears on screen before the signal source—something I don't see in the same crisp white power-up logo on my lamp-based DLA-X790 reference projector. And you can look into one of the exhaust vents at any time the projector is active and see a green glow behind the cooling fan. Hmm...was this was a harbinger of bad things to come?

Fortunately, it wasn't, and though there were some minor issues with grayscale accuracy in the default picture modes, the NZ7 calibrated beautifully and ultimately delivered the kind of performance I hoped for, with deliciously dark blacks, highly accurate color, and the effective dynamic tone-mapping that has defined JVC's successful lamp-based projectors. Based on the company's history, it should have come out of the box looking better, but I have little doubt that the default tuning will improve over time. In the meantime, making the modest adjustments I described above provided a simple fix for those who don't want to pay for professional calibration.

At this point, there is no direct competition for a laser-driven home theater projector of this quality at the $9,999 price point; one would need to consider Sony's LCoS-based VPL-VW915ES at $19,999. JVC's new step-up model, on the other hand, is the DLA-NZ8 which, at $14,999, adds the four-phase pixel-shifting for 8K content and, more critically for image quality, doubles the NZ7's rated native contrast to 80,000:1. Assuming that projector actually performs with a commensurate improvement in contrast, this could very well become the sweet spot in the new product family.

On the other hand, if your budget is stuck at $10K, there's a consideration today about whether to jump on the NZ7 or grab a lamp-based DLA-NX7, JVC's current and highly popular mid-line projector, before it disappears for good. Despite sharing the "7" in their model designations, these are not comparable products in performance specs. While the NX7, at $8,999, sacrifices the laser and future-proofed HDMI ports, it shares the same 80,000:1 contrast ratio as the new NZ8. If contrast and black level remain your number one criteria and you're not married to the idea of eliminating lamp replacements, there's an argument to be made for it. Keep in mind, too, that despite the convenience and stability of laser light engines, they are typically limited to 20,000 hours life with, in most cases, no cost-effective path to laser replacement. A lamp projector can potentially be pushed much longer with new bulbs.

Of course, if you've got your heart set on a state-of-the-art laser projector with an amazing picture and modern amenities that will carry you into the future like HDMI 2.1 and 8K signal capabilities, not to mention the ability to play games at 4K/120Hz, you can't do much better for the price than the DLA-NZ7. It's a high performer, an incredible value in its laser projector class, and a sure pick for ProjectorCentral's rare Editor's Choice Award.

Measurements

Brightness. Unlike many projectors, the JVC DLA-NZ7 does not have a specific picture mode designed to make its brightness spec, but some adjustments to one of the SDR modes has the effect of placing it into its brightest output. Specifically, setting it to one of the SDR User modes, then selecting the Off position for Color Space and the High Bright color temperature, results in maximum light. With these settings, the projector measured 2,213 ANSI lumens, just over its 2,200 lumen spec. However, these settings result in a heavy green cast that most viewers would find unacceptable with any real content.

Measuring all the presets in their default settings but with the LD Power laser setting at its High position provides a more realistic picture of what users will encounter day-to-day. The measurements for all the modes with the three LD Power settings are below. Note that when the HDR Frame Adapt mode is set to Frame-by-Frame analysis, the full-frame 100% white pattern used for measurement triggers a boost in output vs. the Scene-by-Scene setting that is reflected in the chart. This was not observed while viewing content.

Zoom Lens Light Loss. Moving the long 2X zoom from its widest position to its longest telephoto position resulted in a 28.8% loss of light output. While significant, this isn't unusual for such a long zoom lens. As always it behooves users to position the projector as close to the screen as possible to preserve light output, especially for a large screen.

Brightness Uniformity. The lens exhibited good uniformity, resulting in measurements of 87.0% at wide zoom and 83.4% at long zoom.

Input Lag. The DLA-NZ7 has a Low Latency switch in its menu that is available in all picture modes and must be engaged for videogame play. With Low Latency on and e-shift pixel shifting turned off I measured a low of 36.0 milliseconds of input lag with a 1080p/120 Hz signal using a Bodnar 4K lag meter. 1080p/60 Hz measured 36.5 ms. 4K/60 Hz signals (3840x2160) measured 44.7 ms. This is acceptable input lag for casual gaming but probably too slow for competitive games that require fast response time. Note that the projector also accepts 4K/120 Hz signals from the latest gaming consoles, but I was unable to test that response time with the Bodnar meter. With Low Latency turned off (along with e-shift), 1080p/60 input lag was a very high 163 ms.

Fan Noise. As noted in the review, the DLA-NZ7 is a relatively quiet projector. It is rated for 24 dBA in Low laser mode using the standard factory lab measurement that averages four readings around all sides of the projector in a soundproof chamber. My casual measurements taken five feet in front of and two feet below the projector, essentially in line with the exhaust fans, resulted in a reading of 37.1 dBA with the LD Power setting in its Low or Mid setting (in a room with a 27 dBA noise floor). The High laser setting measured 38.6 dBA and was a bit higher pitched but was easily masked by soundtracks. Engaging the High Altitude mode drove noise to 43.3 dBA at a noticeably higher pitch, but was still surprisingly tolerable; you might get away without acoustically isolating the projector if it can be place a modest distance from viewers. Also, there was no high-pitched electronic whine that accompanies some laser engines.

Calibrated Settings

Calibrated image settings from any third-party do not account for the significant potential for sample-to-sample variation, nor the different screen sizes and materials, lighting, lamp usage, or other environmental factors that can affect image quality. Projectors should always be calibrated in the user's own space and tuned for the expected viewing conditions. However, the settings provided here may be a helpful starting point for some. Always record your current settings before making adjustments so you can return to them as desired. Refer to the Performance section for some context for each calibration.

Thanks for another detailed review Rob. Any idea when you guys will be getting your hands on an NZ8?
Rob Sabin, Editor Posted Sep 19, 2021 10:55 AM PST
Sorry Tango - no idea. They have very limited sample availability at the moment but maybe once the units are released at the end of October.
James Finnie Posted Sep 19, 2021 10:57 AM PST
Thanks for the review. Are the low laser Natural and User mode numbers for brightness right? They look decidedly out of kilter with all the other modes measured on the projector, at -48% down from the high bright number at the same laser level. Could you let us know also what calibrated lumens you managed - assuming none of these numbers in the table represent the calibrated lumens?
Rob Sabin, Editor Posted Sep 19, 2021 10:59 AM PST
James, I feel very confident in these lumen measurements, and my experience has been very similar with many other projectors. The reality is that there is usually a significant sacrifice in lumens to achieve accurate color, and most projectors only come close to their top rated number by shifting heavily into green, which this one also does. The difference between this and most other home theater projectors we test is that most of them have a throwaway green picture mode that's just there to make the spec, so they can claim x number of lumens but no one would want to use that mode for anything but a spreadsheet when the sun is streaming in from the windows. In this case, JVC has some special settings to make it do that, but they don't make that a dedicated pic mode or make it readily available or obvious to users, They don't expect or want anyone to actually use it since it's not what this projector is intended for.

I apologize, but I did not take a lumen measurement on the calibrated modes. My calibrated light measured off the 92-inch 1.3 gain screen in Natural mode was 50.6 foot-Lamberts, or about 35 ftL on a 1.0 gain. For the Frame Adapt HDR mode it was 194 nits, or 136 nits on a 1.0 gain.
Scott Langley Posted Sep 19, 2021 11:01 AM PST
Thanks so much for the review!

Did JVC mention any other tweaks they are working on for firmware updates that are still in the works?
Rob Sabin, Editor Posted Sep 19, 2021 11:10 AM PST
Scott, although I'm happy to have a relatively early review to share for the NZ7 and am grateful that JVC provided a sample, the reality is that this product won't be officially released until at least the end of October. They have indicated that the Dynamic CTRL feature is a work in progress and I expect anything uncovered in the reviews they get between now and then--or even a while after initial release--could be fair game for firmware tweaks. I'm sure their intent is to not just get these models out there but to get them as right as they can be.
Mike Posted Sep 19, 2021 11:58 AM PST
Wish JVC had focused on accurate color rather than 8K resolution. If the many reviews of 4K Blu Rays are any indication the human eye has a tough time resolving the differences between 1080P and 4K movies. Just about every reviewer comments on improved color though when comparing the two formats. The JVC REC 2020 spec seems disappointing. Can 8K eshift be turned off?
Rob Sabin, Editor Posted Sep 19, 2021 11:59 AM PST
Mike, I'm sure the modest color temp inaccuracies I saw will be tuned up; JVC has a long history of getting color right. But other reviewers have commented on the limited value of 8K eshift in the earlier NX9, and it remains to be seen if the new e-shiftX technology changes that. Either way, you always have the option to turn e-shift off, which I did.
Mike Posted Sep 19, 2021 1:53 PM PST
I wish that when a projector says it is HDMI 2.1 compliant, it means that it has ALL of the 2.1 specs. It doesn’t look alike this projector has eARC, part of the 2.1 spec as it should to be fully compliant.

Some will say that eARC isn’t necessary if you don’t have native apps in the projector, but that isn’t the case. In the case where your audio processor won’t do 8k/4K, eARC allows you to route from the source directly to the projector and then get the multi-channel sent back to your audio system for use in your theater. Without eARC, you are forced to buy a new processor to comply with the new spec, or get new hardware with multiple HDMI outputs to send one to the projector and one to the processor.
Mark Anderko Posted Sep 19, 2021 9:15 PM PST
A worthy step up from someone, like yourself, that is currently enjoying their 790? Markedly noticeable upgrade in picture quality? Aside from the benefits of a laser.
Rob Sabin, Editor Posted Sep 19, 2021 9:20 PM PST
Most definitely, Mark. I would have said that about the lamp-based NX5 as well. The X790 does have a higher rated contrast ratio (130,000:1 native, which is why I bought it in the first place as a reference). But the NZ7 looks pretty comparable and really looks awesome with torture test dark scenes, despite its much more modest spec. I think that in this and also the NX series (I reviewed the NX7) JVC's excellent light management particularly with the dynamic HDR really counts for something in the final result. As far as a step up from the X790, beyond contrast this is better in every way: 4K native vs pixel shifted 1080p, brighter overall, laser, dynamic vs static tone mapping...
Forceg Posted Sep 19, 2021 9:44 PM PST
Thank you for your review. Does this projector have a dust filter ? with a need for regular cleaning ?
Rob Sabin, Editor Posted Sep 19, 2021 9:46 PM PST
Forceg, I actually don't know. There was no manual ready for me to look at to check maintenance requirements and I didn't ask. I'll do so now and see what JVC says.
David Boulet Posted Sep 20, 2021 5:58 AM PST
"I wish that when a projector says it is HDMI 2.1 compliant, it means that it has ALL of the 2.1 specs. It doesn’t look alike this projector has eARC, part of the 2.1 spec as it should to be fully compliant." My understanding was that JVC wasn't officially listing the HDMI spec as "2.1" for this very reason... yes does use an HDMI 2.1 chipset to achieve 4K210 and 8K60 etc, but because it doesn't implement all 2.1 features, they (JVC) weren't actually publishing a "2.1" HDMI spec directly (if you view their own published material).
Rob Sabin, Editor Posted Sep 20, 2021 7:07 AM PST
I can actually clarify something on this point. JVC does not specifically mention HDMI 2.1 in literature because the HDMI alliance is now insisting that licencees do not mention the HDMI version in their marketing. Dumbest thing I've ever heard, and something tells me this won't hold long term...but JVC will not be the last manufacturer to dodge this critical spec because of pressure or licensing requirements with HDMI.org. The bigger problem I see is that there are indeed different levels of v2.1 implementations just as there was with prior versions. We have now seen two projector manufacturers implement 2.1; LG's version in the HU810 has 24 Gbps bandwidth which isn't enough for 4K/120 gaming, but they did implement eARC...and now here is JVC with full bandwidth 48 Gbps, but no ARC or eARC (which I would continue to argue is really not a requirement for a long throw projector that has no onboard streaming source). But apparently it will be up to enthusiasts and reviewers to get all this figured out from the bandwidth claims being made for each model.
Daniel Posted Sep 20, 2021 12:07 PM PST
I've heard conflicting info on the continuation of the lamp based NX5. Is JVC continuing to make new ones, or is it more of a "while supplies last", like the X790?

I would love to have seen a lamp based refresh with 4k120. The NX5 was already a stretch... I think I'll tear a ligament if I buy the NZ7.
Rob Sabin, Editor Posted Sep 20, 2021 7:11 PM PST
Daniel, my understanding is that JVC wants/needs to continue with a lamp-based model at the critical $5,999 4K D-ILA entry price point where they do a big chunk of business today. So the NX5 goes on for now...
Jun Posted Sep 21, 2021 4:58 PM PST
Thank you much, Rob, for the review. There is so much anticipation on how these new units will perform so the information you provided is very useful to make informed buying decision. One question though. The brightness readings on the preset picture modes are lower than reported readings on the existing lineup (NX5, NX7). One of the variables is the zoom position and I could not find that on the review. Were these readings taken at the widest zoom?
Rob Sabin, Editor Posted Sep 21, 2021 5:00 PM PST
Yes, brightness measurements are always taken at the widest zoom except for when we check the zoom lens light loss.
Andrew Posted Sep 21, 2021 5:06 PM PST
Many thanks for your great reviews. This projector is right in my sweet spot for the jump to 4K and laser source. I just have a general question regarding lasers. I have a 14 foot horizontal Stewart screen and once tried a DLP projector on it and the rainbow artifacts were horrible. Lasers need a color wheel as well so can they suffer from this problem?
Han Wedge Posted Sep 24, 2021 4:54 PM PST
Great review as always! Thanks.

As for picture quality (and only that) would you prefer the NX7 or the NZ7? (especially if combined with a big screen like 130")
Rob Sabin, Editor Posted Sep 24, 2021 4:56 PM PST
Hard to know without an actual side by side. NZ7 has the brighter output, but NX7 has the higher rated contrast.
Victor Posted Oct 8, 2021 2:20 PM PST
Jvc doing killer job with there projectors why don’t they enter the ust projector world?
Rob Posted Oct 25, 2021 1:18 PM PST
How much quieter are the fans on these than their lamp counterparts? Currently own an RS540 and would love for something quieter.
Antony J Newman Posted Oct 26, 2021 3:14 PM PST
"JVC DLA-NX7 ANSI Lumens"

Was this title supposed to be "DLA-NZ7" ?

Seemed a bit strange to list the lumens of the previous (non-laser) model.

Thanks, Antony
Rob Sabin, Editor Posted Oct 26, 2021 3:20 PM PST
Yup, that was a typo in the headline only, Antony -- it's fixed now. Thanks for flagging it.
John Posted Oct 29, 2021 12:35 PM PST
I have a 20.5’ throw to an 8’ wide Draper 1200X-ALR (grey) 1.2 gain screen. My viewing room has minimal ambient light at night (mainly film viewing), but significant ambient light during daytime (mainly sports viewing). I will be upgrading from the DLA-RS25 projector. I would like advice on how much the extra contrast provide by the NZ8 would improve my viewing over the NZ7.
Rob Sabin, Editor Posted Oct 29, 2021 12:40 PM PST
It should be a significant difference in a dark room, John. The NZ8 has twice the rated contrast, thanks in part to a different optical block that helps surpress stray light that is only in the NZ8 and NZ9. You also get JVC's pixel-for-pixel 8K eshiftX feature, which may or may not provide a valuable benefit with native 8K content when that becomes more widely available.
Jose Luis Posted Nov 23, 2021 3:13 PM PST
Thanks for this excellent review. I have the same doubts as Andrew regarding the generation of RGB primary colors with the JVC laser technology. Using a color or phosphor wheel, they will be displayed sequentially favoring the appearance of the rainbow effect. In any case, it is easy to check simply by moving fast a finger in front of the screen; if it is not continuous, but intermittent, there is color sequencing. And the optical supplement for the e-shift, in the DLP projectors that use it, the black level and the contrast of the image are usually reduced compared to the normal 1080p versions. Does the same happen with these models respect the NX series?
Rob Sabin, Editor Posted Nov 26, 2021 8:50 AM PST
To both Jose and Andrew: This is a 3-chip projector and did not suffer from any rainbows or other color artifacts in my testing. I don't know enough about the technology to understand how sequencing comes into play when extracting the red and green beams from the blue laser, but each chip gets its primary color beam more or less full time, and the typical rainbows we see with single chip DLP projectors just aren't there.
mark Posted Dec 14, 2021 6:34 AM PST
HI!

I use this for a midscale UNREAL-5 Projection. About 3 x 2 Meters. Works fine.. ( yes the ILM 10.000.000,- usd $ facility works finer) But this is the start line. Next Year we see this under 2900,- usd $.. :)
Cory Posted Dec 17, 2021 1:20 PM PST
But that price though! Here’s to hoping Epson’s next laser pj is less than a car.
Rob Sabin, Editor Posted Dec 17, 2021 1:25 PM PST
Cory, I'm counting on the fact that we'll be seeing better and better performance from more and more affordable laser projectors in the coming days, though I think the gold standard blacks provided by LCoS will always be at these kinds of premiums. That said, the fact that JVC is delivering LCoS-based laser projector for half the price of Sony tells you something about how prices have been set in the past and the fact that there's more aggressive competition heating up in this sector.
Jose Luis Posted Dec 18, 2021 12:29 PM PST
It is curious that while JVC, LG, Optoma and others use only one or two Lasers in their projectors and add a phosphor/mirrors wheel (moving element subject to wear, rainbow and noise) to generate the other colors, in the UST versions with DLP already they employ three or four independent lasers. I'm very surprised as it doesn't seem to be a lumen level problem; the LG HU85 has 2700 lum, but the new NZ7 only 2200 lum...
Kevin Prouten Posted Dec 19, 2021 10:05 AM PST
Ok Santa you and me need to talk. Less socks more JVC.
Grant Posted Dec 21, 2021 2:46 PM PST
I curious about how you calibrated the NZ7. Did you calibrate using the colour temperature of 7500 or 6500? You mentioned in your review that 7500 was the most accurate out of the box, however, I think you calibrated using the projector's 6500 setting. IIn a review I recently read of the NZ9 -- the reviewer used the 7500 temperature setting for his calibration and retained nearly all of the projector's claimed light output with accurate greyscale and colour.
Rob Sabin, Editor Posted Dec 21, 2021 7:19 PM PST
Grant, the D75 color temp out of the box was the closest to an actual D65 measurement, so it was a preferred default setting, but the D65 setting was easily calibrated to conform to its label. I didn’t see the need to stay with the D75 setting as the color controls had plenty of range..
Piet Bakker Posted Dec 29, 2021 2:54 PM PST
What I wonder, is it possible to replace the laser like a lamp after the maximum burning hours. It is very possible that the machine will be purchased. Now owning HD750.

Piet Bakker NL
Andy Posted Jan 9, 2022 5:53 AM PST
So given the quiet, near viewer comment, is the 2-way eshift on this much quieter than the ESX on the NZ8? The NZ8 is unusable near viewers due to the truly dreadful test-tone whine from the eshift. It's OK with it off in low or medium laser. Oddly the NZ8 no longer seems to have an option to put it into non-X eshift like I thought I had seen on pre-production reviews. I'd love to see a recording of 2-way vs 4-way noise and preception.
Rob Sabin, Editor Posted Jan 11, 2022 7:55 PM PST
Andy, thanks for the info hear. This is the first I'm hearing about issues with the whine from the NZ8, but I never heard any significant noise added to the room when flipping the regular e-shift on and off with the NZ7. Of course, it would make sense that doubling the frequency of the shifting to 240Hz could conceivably generate a different pitch or louder sound. I would say that I am surprised that there would be no way to turn e-shift off in any of the NZ models, but this is something I can inquire about.
Scotty Smith Posted Jan 17, 2022 9:16 AM PST
Live the review and have decided to purchase this… my media room has a depth of 19 feet (throw distance is about 5’ less), what size screen would your recommend. the width of the room is 13’. Also, what type of screen would be best; the room is pretty dark. Thank you soooo much.
Rob Sabin, Editor Posted Jan 17, 2022 9:20 AM PST
Scotty, if your room has pretty well controlled light you should go for a high quality matte white screen with a high end projector like this to insure you get the smoothest surface (with no texture or sparklies you can get with some ALR screens) and no color shift. You're going to want to calculate the exact throw distance you have to the front of the lens then factor in the considerable depth of the projector, but I'm guessing you can really go beyond 120- to 125-inch diagonal, which should be very cinematic and will still get you quite a bit of light output in the calibrated modes. Don't go any higher than 1.3 gain, which will definitely add some extra oomph for HDR or ambient light viewing, and if you have any severely off-axis seating you might want to go with lower 1.0 or 1.1 gain to widen the viewing cone a bit.
Roderick Covington Posted Jan 17, 2022 9:59 AM PST
Rob once again your review spot on Thank You. Did the new software softfine the picture in favor of 4k120hz and 8k60hz? I may be asking in vain you did state you did not demo other resolutions.And any new blu ray players to take advantage of this upscaling in the future? Again your review very well thought out and to the point.
Rob Sabin, Editor Posted Jan 17, 2022 10:00 AM PST
Hi Roderick, thanks for the comments. I'm afraid I did not try 4K/120 or 8K/60 with the NZ7 as I had no generator/source that would do that. Of course, this unit only does the two-phase 120Hz standard e-shift pixel shifting, which certainly softened (just subtly) native 4K/24 movie content. One thing I can say is that a demo I just saw at CES of the NZ9 playing native 8K/60 with the 240Hz e-shiftX tech was stunningly sharp.
Dave Posted Jan 17, 2022 12:59 PM PST
Hi Rob, many thanks for your efforts. Do you plan on reviewing the DLA-NZ8 anytime soon? In a light controlled room, I am wondering how perceptible the black level differences are between the NZ7 and NZ8, I know what the specs say but beyond a certain point black is black.
Rob Sabin, Editor Posted Jan 17, 2022 3:34 PM PST
Dave, we have requested a sample but they are very hard to come by right now; JVC is backordered and every unit that comes in is spoken for.
Jerry Posted Feb 15, 2022 6:26 PM PST
I already have a nx7 with Stewart screen 133 width. The length of my room is 22 feet and have the projector ceiling mounted at 17.5 feet. I sit at 20 feet as there is no front row. I really couldn’t see 8k from as far back as I’m sitting but I want a brighter picture. My room dedicated light off black. NZ7 or spring for NZ8. What difference will I see for price difference.Thanks for these reviews.
Rob Sabin, Editor Posted Feb 15, 2022 7:26 PM PST
Jerry, the leap to the NZ8 is the only move that would make a serious dent in giving you noticeably more brightness. You'd be leaping from 1900 to 2500 lumens in max output, which is considerable, while keeping your rated contrast at the same 80,000:1 spec. The NZ7 will do little to nothing for your brightness on that big screen and potentially raise your black level with rated contrast that's half of your NX7's.
Rob Holloway Posted Feb 22, 2022 8:08 AM PST
Nice review Rob. I have the RS1000/NX5 in a 19 foot light controlled dedicated theater projecting onto Stewart 1.3 gain 150” 2.35 aspect ratio screen. I’m a happy camper. Is the NZ7 going to make real difference to my film watching experience? thanks, Rob

Rob, I think it would be tough to justify making that change. You gain the solid state light source, a little more brightness (400 more lumens, not enough to make an enormous difference) and the HDMI 2.1 ports for future 8K content as well as 4K/120 hz gaming (albeit with mediocre input lag). But to spend $11,000 to upgrade to a projector using the same imaging chips and spec'd with the same native contrast seems silly to me.

I'm deciding between the upcoming NP5 and the NZ7. The price difference seems substantial for a very similar projector other than light source. Aside from having to change bulbs regularly to maintain brightness on the NP5 do you feel the laser light engine otherwise improves performance in any substantial way over it's lamp based counterpart? Let's assume the NP5 performs the same as the NX5. Thanks.

Jason, I think you can make a very good case here for going with the NP5 if you're not married to the idea of a solid state light source. As noted in my comment to Rob above, we are again talking about three projectors with relatively close specs in terms of brightness and rated contrast, and all using the same imaging chips and lens.

Hi Rob, thanks for the review. I’m trying to decide between the NZ7 or NZ8. I can get my room as dark as I want and I can choose the throw distance anywhere between 10 and 20 feet. I sit 11,5 feet away from my screen (No other choice because of rear surround speakers, plus I like immersive ;)

1: Will both projectors be able to light up a 150” screen enough for HDR viewing? Will the NZ8 be clearly better because of the greater contrast or lumen output, knowing I can get the room pitch black? 2: Will my seating position (11,5 feet) be ok for a 150” screen? Or is my love for immersiveness getting the better of me and should I dit a little further or take a smaller screen? Thanks in advance Rob, best regards!
Rob Sabin, Editor Posted Mar 21, 2022 7:27 AM PST
Arnaud, both of these projectors should give you a great in image at 150 inches in a dark room, and if you have the budget for the NZ8 the best reasons to step up are probably the higher rated contrast and, for whatever it's worth in the future, the full quad-phase pixel shifting that puts all the pixels in an 8K signal on screen. At for your ability to hit 150-inches, you should check our throw calculator, which says that the closest you can get for a 150 is a lens-to-scree=n distance of about 7.5 feet.

Hi Rob, I posted earlier and ended up buying the NZ7. It is very bright on my 180" screen and the black level is plenty dark. I found that where the source material specifies pure black, the projector is close to it. The SDR calibrations seem spot on. The HDR10 calibrations are producing a very red image with washed out contrast (I've rechecked my input 3 times to make sure no mistakes were made). Is it possible the menus have changed slightly since you posted the calibrations? I noted that I had to force the "auto" to select HDR10 using an Aquaman 4K disc source. The 4K source looks pretty good in SDR but again red and washed out in HDR10, this happens with Netflix also. Any thoughts on HDR10 calibration?
Rob Sabin, Editor Posted May 3, 2022 11:38 AM PST
Dave, it is certainly possible that JVC tuned the projector's faults since I reviewed it and they starting shipping in earnest. I would suggest making sure that your Color Space is properly selected for HDR; you should be using the Rec.2020 setting and your projector should be set to automatically select that as part of whatever you choose as your default HDR setting. You'll really want to use the Frame Adapt mode as the default HDR setting that the projector selects when it sees and HDR10 flag in the content.

A close friend purchased a NZ7 and had it calibrated. It looks great to me but his DCI P3 was 88 which is lower than I had expected. Wondering how this will affect picture quality and is this a deficiency with this projector?
Rob Sabin, Editor Posted May 29, 2022 10:55 AM PST
Richard, this is exactly in line for this projector and higher than what I measured in my sample. JVC does not claim 100% DCI-P3 for this model; as noted in the review the step ups have a filter that provides that at the expense of some brightness. Bottom line: full DCI-P3 coverage is nice to have given that the HDR content is produced to that spec, but you don't encounter content frequently that makes use in any noticeable way of that difference between 88% and 100% (though it depends on where the deficiency is in any given projector model's volume profile). I do think we have all become a little obsessed with these numbers to some extent, but very few projectors, even premium models like these JVCs, actually can produce 100% DCI-P3 without a color filter of some sort. The execption are the triple RGB laser UST models, but most of those have deficiencies in other areas where these JVCs and the Sony LCoS models excel.

Great review per usual Rob, thanks. I’m considering the NZ7 to replace my blown Epson 5050ub. However with only 140” throw distance I would need 2x zoom to fill my 106” screen. Am I to understand that I would be losing 28% brightness in this situation with the NZ7?

I’m also considering the Epson LS12000 based on more flexibility with short throw distance and more lumens, (and much easier mounting options at 1/2 the weight.) Do you have a recommendation for this situation or are these projectors in two different classes with the JVC being in the upper class in terms of overall image quality? My theater is dedicated and dark. WWRD? Thanks!
Rob Sabin, Editor Posted Jul 21, 2022 6:41 AM PST
Jim, it is the opposite. The long telephoto setting is the one that would incur significant light loss. In your case, with a 106 inch image and approximately 11ft-8in throw, you're actually at nearly the full wide angle/wide open setting on the lens and enjoying all of the available firepower for any given mode. Lock your Throw Distance into our calc and set image size to 106 inches diagonal 16:9 and you'll see what I mean.

I haven't been able to look at the NZ7 next to the Epson but I tend to believe that the JVC is indeed in a different class. One thing you'll get is a sharper image due to the native 4K imagers, although the Epson with its pixel-shifting plus enhancement circuitry is excellent in this regard and compared favorably to the Sony XW5000ES in a recent test I did, though the Sony has an inferior lens. But if I had the budget, I'd be looking at the NZ7 as a step up from the LS12000 for a variety of reasons including the excellent frame-by-frame tone-mapping and a very high degree of additional adjustability for professional calibration that the Epson doesn't have.

Hi, after much internal debate, I picked up one of these and am so far very happy with it. Had some hassle getting it to fit in my basement far enough away to throw to my 120" screen and fill the screen, but worked out in the end.

I'm wondering though if you know what the point of the LAN port on this thing is for? I've tried to search around online, but I could not find any resources that helped me. I tried plugging it into my network but it didn't seem to connect, and firmware updates seem to be only via USB drive.

Bit confused.

On a side note, I was having a bit of buyers remorse when I started reading about the NZ8, because it seems to have better contrast, and a better 8K e-shift. The latter is not such a big concern to me now, but the former could be. Thoughts?

Thanks, BR

Hi Rob, I am looking at a new projector and was interested in the xw5000es which seems to do everything decently well. I however did come across a good deal on the NZ7 and was wondering what your thoughts were on if it was worth the stretch from the Sony as your do have the sony rated no.1 in the above $5K category. My concern was if the video processing in the Jvc was as good as the sony x1 ultimate with motion etc as I am a bit sensitive with motion judder. Thanks
Rob Sabin, Editor Posted Sep 13, 2022 8:29 AM PST
The NZ7 is without doubt the preferred projector if you can make it work within your budget. It has the superior (and powered) lens, superior (dynamic) HDR tone-mapping, is brighter by 200 lumens, and is capable of achieving deeper blacks.

Bought this projector and am quite happy with it. In my room, the low power mode may be adequate but the mid power mode provides a more punchy SDR picture. In deciding which to use as my default I had the following question. Would operating a laser projector like this one in low power mode instead of mid or high extend the life of the projector, i.e., reduce the rate at which the brightness of the projector drops over time as is the case for lamp based projectors?
Rob Sabin, Editor Posted Nov 15, 2022 8:33 AM PST
Havish, running any laser projector at less than full power usually does extend the life of the projector by some amount. I don't know specifics for JVCs engine but typically commercial projectors run in their ECO modes, which average 60% to 50% brightness off peak output, will stretch their lives to as much as 30,000 hours from a 20,000 hour minimum at full power.

Keep in mind, though, that regardless of where you run the projector, it's drop off of light output over time will be very minimal; this is the beauty of laser. If you run at full power it will lose modest brightness over time but nothing like the drop off in a lamp's output. And when you reach the end of the guaranteed hours, you will see a full failure of one or more laser diodes or diode banks, which may or may not spell the end of the projector's life. Just depends on the projector and what has failed.
