Our Take

The Optoma UHZ50 might be marketed as a solid gaming projector—which it certainly is—but it also offers great performance for a movie night or watching cartoons in the morning with the family, all in an affordable, laser-driven package.

Optoma UHZ50 front angle

We are seeing more and more the release of solid-state projectors in favor of lamp-based models. There isn't the need with these projectors to invest every couple of years in a new light source, as there is with lamp models, and they run significantly cooler with less power draw (and therefore cost). And with laser light source projectors getting cheaper, the solid-state technologies are beginning to compete with the brightness of lamps.

Most home theater laser projectors you find today are of the ultra-short throw variety, but the Optoma UHZ50 is a standard throw option that comes in at under $3,000—it currently carries of a street price of $2,799—and is one of the only 4K HDR versions at that price. It's also the only one that is designed for gamers, touting a very low input lag of 16.7 ms at 60Hz and down to 4 ms at 240Hz. It's poised to become the go-to option for gamers who still want great performance while watching TV and movies.


The Optoma UHZ50 is a DLP projector with a single 0.47-inch DMD that uses 4-way XPR pixel-shift technology to achieve 4K resolution. It has a laser light source that is rated at 3,000 ANSI lumens (we measured 2,503, well within the accepted 20% ISO21118 tolerance). At the time of this review, it is one of the least expensive 3,000 ANSI-rated solid-state 4K home theater projectors on the market—only the ViewSonic LS700-4K (which did not review favorably for home theater) has a lower street price. (You can see a full list by searching the Projector Central Find-a-Projector Database). As with all laser projectors—and all solid-state projectors, for that matter—the UHZ50 doesn't require a replacement light source. The laser light engine is rated to last up to 30,000 hours until it reaches half brightness.

Compared to a LED projector, laser light has two distinct benefits. Laser technology currently has the potential to create a brighter image with more accurate color, although LED is making strides in this department (the BenQ X1300i 1080p LED projector has similar light output to the UHZ50 and it will be interesting to see if measurements of the upcoming X3000i 4K version will match it). Black level, and therefore contrast ratio, on laser systems tends to be better as well, which can lead to an image with more depth. Contrast ratio in particular is definitely one of the wins with the UHZ50 over recent LED projectors I've seen that have struggled with achieving decent blacks.

Optoma UHZ50 lifestyle1

Over the past few years Optoma has put a good deal of focus into producing projectors aimed towards the home theater gamer, specifically in regards to low input lag, and the UHZ50 continues that (although it doesn't have the gamer-centric picture settings specific to different game types that I discuss in our BenQ X1300i review). With the UHZ50's Enhanced Gaming mode enabled, Optoma lists a low input lag of 16.7ms with a 1080p/60Hz signal—I measured 16.9 ms—and down to 4 ms if sent a 1080p/240Hz by a computer. While the projector is capable of high refresh rates, all three of its HDMI inputs are version 2.0, so 4K refresh rate is limited to 60Hz. (We've begun to see projectors with full-bandwidth HDMI 2.1, such as the JVC DLA-NZ7, but they are still far from the norm.)

One of the ways the UHZ50 achieves this low input lag is by turning off any extra processing functions—specifically menu items for Aspect Ratio, Zoom (digital zoom only, manual optical zoom is unaffected), Image Shift, and Geometric Correction. If you plan on gaming with the UHZ50 take extra care during setup that it's square and centered to the screen so no digital image adjustment is necessary (which is always best to avoid anyway as they can adversely affect brightness or add artifacts). To make sure your room's spacing is adequate for the 1.3x zoom, be sure to look at ProjectorCentral's Optoma UHZ50 Throw Distance Calculator. Near the manual zoom there is also a lens shift adjustment for vertical offset that ranges from 105 to115%.

Two additional points of note: Enhanced Gaming can be turned on for any picture mode—it isn't reliant on being in Game picture mode (although Game picture mode does boost shadow detail that can be helpful to see enemies in first-person shooters). And it is only available for sources plugged in to HDMI 1. So if you're running more than one console (or a PC as well), you'll need to run through an AVR for switching, or be ready to physically switch HDMI cables back and forth. I recommend the former, both for ease of setup and for the ability to have a robust sound system. The UHZ50 comes with speakers, and while they're serviceable in a pinch, their sound is thin and uninspired. For any sort of auditory immersion you'll need additional speakers.

Incidentally, Optoma's motion interpolation technology, PureMotion, is only available on the Home screen and for sources connected to HDMI 3. This could cause more HDMI cable switching, or needing to run two HDMI cables, if you're a fan of motion interpolation. Personally it's one of the first things I turn off if it's on and have only rarely used it for live fast-moving sports.

While many manufacturers are jumping on the Android TV OS bandwagon, Optoma has chosen to use their own solution. The projector doesn't come with any apps preinstalled, so anything you want needs to be downloaded from the Optoma Marketplace. There's a very important disclaimer on the Optoma website that I'll provide here in full. "Note: Optoma projectors run on a customized version of Android. Google Play Services not supported. Not all third-party apps will be compatible and can vary in quality and resolution." The Optoma Marketplace interface and that disclaimer make it look like the customized version of Android is either Aptoide, which Optoma has used in the past, or at least a close relative.

Optoma UHZ50 remote

The Optoma OS is a bit better than the last Aptoide OS I used. Netflix, for instance, looks significantly better than the low-res option that used to be available (the UHZ50 upconverts what I suspect is a 1080p signal to 4K as it looks ever so slightly softer than the same program on my Roku Ultimate). But navigating app menus is frustrating, especially since the Optoma remote is not designed to act as a streaming remote and is missing transport controls. Beyond that oversight, I like that Optoma decided to include a smaller, thin remote. It's not overloaded with buttons and has a nice not-too-bright backlight that activates with a button press. Does it function well as a streaming remote? No. But Optoma Marketplace doesn't function all that well as a streaming service, so I'd recommend being ready to purchase a Roku, Amazon Fire, Apple TV, or Chromecast (and make it the 4K version to take advantage of the UHZ50's resolution).

There's a good collection of connections on the back of the Optoma UHZ50. It comes with three HDMI 2.0 inputs with HDCP 2.2 (HDMI1 has eARC and allows for Enhanced Gaming, while HDMI 3 has PureMotion), three USB 2.0 (one for firmware updates), a digital optical out, 3.5 mm analog audio out, RS-232, 12V trigger, and 3D sync for an external RF emitter. There's also an included wireless dongle to plug in to one of the USB ports to enable wireless connectivity.


Color Modes. The Optoma UHZ50 has seven SDR picture modes—Cinema, HDR Sim., Game, Reference, Bright, User, and 3D—as well as HDR and HLG readily available. An ISF calibrator can unlock ISF Day, ISF Night, and ISF 3D picture modes for a calibration which can then be locked so errant adjustments (and extra calibration costs) can be avoided.

Optoma UHZ50 top

Bright picture mode tends towards green. This is often the case with a projector's brightest mode as we perceive green as brighter than red and blue, and while it isn't the most egregious green tint I've seen, it casts a pallid tone over everything. Cinema (slightly blue with better grayscale tracking) and Reference (slightly green with better color point accuracy) are better out-of-the-box choices. And while they both are watchable, I'd recommend a calibration to improve grayscale and an oversaturated blue. The UHZ50 has gain and bias controls for white balance/grayscale, and RGBCMYW color point adjustments to dial in a highly accurate picture.

Calibration was a bit of a dance between grayscale and color. After profiling the projector in the User picture mode using Portrait Displays' Calman color calibration software, my X-Rite i1 Pro 3 spectrophotometer, and my Murideo Six-G pattern generator, all color points showed a deltaE value of 2.8 or lower, with red, green, cyan, magenta, and yellow at 1.8 or lower. Grayscale was mostly at a deltaE of 3 or lower, except between 60 and 80% white where the projector bumped up above 4 dE and leaned slightly magenta. This was my middle-ground compromise. Grayscale could be improved at the detriment to color and vice versa. Both the Film and 2.0 gamma settings tracked closest to the BT.1886 curve and are best for a light-controlled room. If you have some ambient light, the Video and 1.8 settings (which both track closer to 2.0) could be a good solution. My SDR settings can be found below in the Calibrated Settings section, but as always only use them as a starting point as there can be significant variation between product samples.

HDR has two dedicated adjustments, HDR Picture Mode and HDR Brightness. The four HDR Picture Mode options—Bright, Standard, Film, and Detail—are fine adjustments to color saturation and detail. For most of my viewing I preferred to keep it on Standard (the default), which kept a nice balance to the image. HDR Brightness is an 11-point slider from 0 to 10 that changes the overall brightness. The low end of the slider can get pretty dim and lose shadow detail while the upper end (around 8 and above) can look blown out with bright material. To my eye, 7 gave enough extra pop. HDR calibration on projectors can be a bit finicky, so I chose to keep the out-of-the-box settings.

SDR Viewing. I'm not sure if it's because I've been stuck inside for two years awaiting a return to eating out at restaurants, but I've been on a cooking show kick. Recently I've been going back to some episodes from this season of The Great British Baking Show. While seeing the showstoppers being presented for Cake Week I caught myself salivating. They say we eat with our eyes first, and the UHZ50 certainly displayed a feast. The decorative colors of the cakes stood out and the detail accentuated the moistness of the cake's interiors.

The brightness of the UHZ50 holds up well against ambient light. With a six-year old, a lot of casual viewing is cartoons during the day with the curtains open. There have been plenty of projectors I've reviewed in the past where my son immediately asks for the curtains to stay closed, but that never happened with the Optoma. In Cinema picture mode, the colors of Nature Cat and Bluey are still vibrant and the image doesn't look washed out. Still, for anything with lots of darker scenes it's best to draw the curtains again or wait until evening, but that's a good general rule for any projector.

With that darker content you might be tempted to use the Dynamic Black brightness mode for increased contrast, but I'd recommend against it. There's sometimes a subtle shift in color tone when it's turned on and there are times you can also see it working, particularly when the image is fading to black. The fade isn't always smooth and instead there are distinct steps visible.

HDR Viewing. The lightsaber battle between Luke Skywalker and Kylo Ren on the planet of Crait is one of my favorite cinematic moments of The Last Jedi (a movie full of beautifully constructed scenes). There's a bright yellow sun blaring behind the on-looking walkers that the UHZ50 displays with great brightness, the red of the planet's surface as Kylo's foot pushes aside the white salt is vibrant, and the detail in both Luke and Kylo's clothing is excellent. Skin tones all look accurate without deathly pallor or inadvertent sunburns.

The HDR Brightness slider wasn't consistent in how much it affected the image. With The Last Jedi (streaming on Disney+ through my Roku Ultimate) there was a pretty drastic range from dim image to overly bright as I described in the section above. But with Blade Runner 2049 on Blu-ray played by my LG UP870 (at 24fps) the setting changed to 3 (from 7) and didn't have any effect on the image brightness. Nonetheless, the picture looked great. This film is notoriously dark and difficult for projectors to properly display, but the UHZ50 did a really good job. The dark interior of Sapper Morton's home at the beginning of the film had great shadow detail to where I could easily see the imperfections in the wall's painted surface, and there was good depth to the room. It didn't feel flat as it can on lesser displays.

The projector had a bit more difficulty during the furnace scene when K finds the carved horse, but only during some of the wider dark shots. Detail is still visible in the metal surface of the furnace as K is crouching down in front of it.

Gaming. There is nothing quite like swinging through the buildings of New York City at night in Spider-Man: Miles Morales. Insomniac did such a great job with the graphics and controls on this game, it feels so intuitive to leap from one building to the next. Motion is smooth and there's loads of detail on the PS5. Even at 60Hz (the highest refresh rate for the game) I couldn't feel any delay while fighting criminals (which is of utmost importance in Miles Morales, as the fighting relies on combo timing to complete some great moves). It's important to remember to switch on Enhanced Gaming before playing as there's no auto low-latency mode. Delay with it off isn't terrible by any means (in the low 30s), but you can still feel the difference with it on.

Optoma UHZ50 lifestyle3

When playing a game in 120Hz mode on the Xbox Series X (as long as you change the settings to 1080p/120Hz and turn off HDR), such as Psychonauts 2, everything is nice and fast. Motion is smooth and the bright, exaggerated colors of the game look great on the UHZ50. The same can be said for Sea of Thieves, but I preferred to re-enable HDR (which puts it into 4K mode and disables 120Hz). It adds to the graphics of the game, especially the detail and highlights of the sea.

3D Viewing. 3D looks great on the Optoma UHZ50. When Scott is sitting in the police car at the beginning of Chapter 15 in Ant-Man there's great depth—from the front windshield through the front and back seats to the rear window, you can see separation between each layer. That continues in Cassie's room as he battles Yellowjacket on the toy train set and thrown toys extend out of the image. There's also enough brightness in 3D that explosions still pop.

I used DLP-Link glasses and had no issues with losing sync, but there's also a 3D Sync out on the projector for an outboard RF emitter if you choose to go that route.


Solid-state technologies have been seen as the future of immersive home theater projectors for a while now, and there can be little doubt that lamp projectors are on their way out in the entry and midrange markets. LEDs have been the dominant solid-state option under $3,000 unless you're looking for an ultra-short throw projector. But the cost of all laser projectors is coming down and they bring with them their benefits over LED—namely higher lumens output with better black level. The Optoma UHZ50 delivers on both counts.

The UHZ50's out-of-the-box performance is very good (although a calibration at this price point is always recommended to get the most out of your investment). The projector's color and grayscale accuracy can be dialed in well (although with some compromise over color vs. grayscale priority), 4K detail is excellent, it has incredibly low input lag for gaming, and its HDR performance is better than LED projectors in its class. You'll definitely want a speaker setup to pair with it, though.

Gamers will still lament that there's no HDMI 2.1 a year after the next-gen consoles were released (and I feel your pain), but a sub-$3,000 HDMI 2.1 projector is still a little ways away. There's a potentially worthy 4K LED gaming competitor on the horizon (the BenQ X3000i), but right now and for the foreseeable future the Optoma UHZ50 offers some of the best value vs. performance for a home theater gaming projector.


Brightness. The Bright picture mode with Constant Power 100% brightness mode outputs 2,503 ANSI lumens, which is 83.4% of Optoma's 3,000 rated ANSI lumens and within the 20% tolerance of the ISO21118 specification. Color brightness (with Brilliant Color at 10) is 59.2% of white.

With a full white field, Dynamic Black drops brightness by 1.7%, but it adds a purple-ish tint and with real-world material there are visible steps to its brightness adjustments and some flicker when it's working. Eco power mode drops brightness by 19% and Constant Luminance drops brightness by 12.8%. Constant Power can be set by 5% increments from 100% down to 50%. Brightness output measured consistently about 2.5% above the listed percentage, except for the 55% and 50% setting which straddle 55% output by 1% on either side.

Optoma UHZ50 ANSI Lumens

Mode CP 100% Dynamic Black Eco CL 85%
Cinema 1,194 1,186 979 1,053
HDR Sim 1,684 1,672 1,381 1,485

Bright 2,503 2,461 2,032 2,186
User 1,909 1,896 1,565 1,684

Zoom Lens Light Loss. From the widest zoom to the maximum telephoto setting, the light output in Bright lowered to 2,105 ANSI lumens—a 16% light loss.

Brightness Uniformity. Brightness uniformity in both the widest and telephoto zoom setting measured 78%, with the greatest difference between the middle top and bottom right portions of the screen, which was visible with a full white image. I didn't notice the difference while watching content or playing games.

Input Lag. The UHZ50 measured an input lag of 16.9 ms with both 1080p at 60 Hz and 4K at 60Hz signals with Enhanced Gaming enabled (without enhanced gaming enabled it was 33.6 ms.). A 1080p/120Hz signal had an input lag of 8.5 ms.

Fan Noise. The Optoma UHZ50 is rated for a typical level of 27 dB and a maximum of 29 dB using the multipoint standard in a sound-controlled environment. With the picture mode set to Cinema and the brightness mode set to Constant Power 100% in my living room that has a noise floor of 29.5 dB, I measured a noise level of 34 dB from a distance of 3 feet below the ceiling-mounted projector. Changing to Eco dropped the noise to 32.5 dB. I never found the noise to be distracting when watching.

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.

Finally, I have waited long. Nice review, Can you give your opinion on which one (LG HU810PW or Optoma UHZ50) is better for overall viewing experience (Gaming(casual like Uncharted, God Of War, Resident evil etc and not competitive), Movies, Shows, don't watch sports or care about it) and I am picky about 3d feature as well if its there they cool if not then I am ok with it as well. What I want better HDR picture (and SDR ofcourse), better picture quality(detail, sharpness, blacks, whites, color accuracy and color brightness etc). So which one you think i go for or should i wait for the Epson EH-LS12000b/11000w?
Qaz Posted Dec 29, 2021 12:08 PM PST
Great review thanks. Has pretty much what I'm looking for to replace my troublesome 4-year-old UHD65, except missing the HDMI 2.1. Dang would be willing to pay an extra $500 for a version with it. Might have to keep looking, might just go with it.
Martin Posted Dec 29, 2021 1:28 PM PST
I have this projector and I am very disapointed. HDR movies doesn´t look good. I have Epson Home Cinema 4010 and it has much better colors. The projector has very loud and annoying buzzing if is 60Hz signal. Do you have the same experience or it is my projector issue? I suppose that SDR setting in the article is in Dynamic Contrast not Eco? Thank you for your answer.
Fitse Posted Dec 29, 2021 4:28 PM PST
Thank you for the great review. I was initially waiting for this review before placing my order, but I have placed it already because it's selling out quickly and after reading this, I'm happy I did!
Mike Posted Dec 29, 2021 6:04 PM PST
Was DCI-P3 color gamut measured and how well did the projector resolve a 4K test pattern. Nice to see Optoma bringing back the superior RF emitter VESA 3D format. Can ISF Day and Night be used to calibrate for SDR and HDR respectively if the projector is used in a light controlled environment. I’m also not clear on how these ISF modes work in conjunction with the various other preset modes such as Cinema, Reference, Etc..I currently own a Optoma HD161X that suffers from painfully slow sync issues such as going from a Blu-Ray Menu to the start of the movie and have read other Optoma projectors suffer from this problem. How did the UHZ50 perform in this regard. And finally does the UHZ50 allow for over the air firmware updates. Thanks.
Owen Posted Dec 29, 2021 6:15 PM PST
I impressed by this thorough review and I would also appreciate a comparison with this Optima UHZ50 to the LG HU810PW or the PB please and soon as I’m going shopping for New Years sales
peter Posted Dec 29, 2021 8:12 PM PST
I have the UHD30, when viewing there's a border around the image (looks like light bleeding along the edges, which get bigger the more you use the optical zoom)... is there a similar light border on this model?
Venkatesan JB Posted Dec 29, 2021 9:51 PM PST
How its compared to previous model UHD50 optoma ?

Wats the color wheel segment RGBRGB or RGBWRGBW ??
Alex Posted Dec 30, 2021 7:09 PM PST
I've noticed I'm not the only one trying to decide between this and the Epson 5050ub. How would you compare the two? I'd be using this in a living room with ambient light for those autumn football afternoons as well as nighttime movies (4K)/Xbox gameplay. We use our current projector 1,500+ hours/year, and we're due for a bulb replacement or a projector upgrade.

Would you say this can compete with the 5050ub for image quality and ambient light viewing?
Angelo Posted Dec 30, 2021 7:09 PM PST
Thank you for the excellent review! I’ve been looking to upgrade my Epson 3100 to a 4K or Faux-K projector. I’ve been really happy with the 3100 and was pretty much set on going for the Epson 5050UB until the UHZ50 hit my radar. I’m curious if you an opinion on which projector would be the better of the two, as they both seem like excellent options that are in my price range. Typical usage would be spread across a 4K Firestick, a Panasonic UB820 4K Blu Ray player, and a PS5. I am a gamer, but nothing competitive and rarely do I play online, so both projectors have an input lag that looks appealing as a mostly single player gamer. My setup is in a fully light controlled room with a 1.0 gain screen, and 7.2 surround, so onboard projector speakers are a non-issue for me. I feel like I couldn’t go wrong with either the 5050UB or the UHZ50, but I’m having a tough time deciding which PJ to pull the trigger on. Hope you might have some words of wisdom! I’m also glad you highlighted both The Last Jedi and Blade Runner 2049 in your review. Two of my favorite movies in recent years and both are visually stunning.
QuackBaguette Posted Dec 31, 2021 12:46 AM PST
Thanks a lot for a great review once more. I've had this projector for a few weeks now and I've been pretty happy about it. I was puzzled by some earlier reviews comments on sharpness - I read 2 was a good base but I find it incredibly blurry on mine, you mention 5 which I could try again, but 10 felt like the good base for me. As I am no expert I really struggle to calibrate it and would probably need a pro pass as you mention, but I still wonder if this is good value for le as I just project on a wall in a living room. On the profiles too, cinema looked ok on mine but reference, which was hailed also in other reviews as a good base, was very green if I remember well. The User profile felt like the best base in my case. I'm so puzzled as to why this is! I probably have a terrible eye, but my experience so far doesn't exactly relate to many so I'm even more puzzled on how it should be calibrated haha. At the end of the day, I'm very happy with it, my partner is too, the brightness is amazing and HDR looks fab. As long as it doesn't have a constellation or issues like my previous BenQ w2700, it feels like a keeper. Thanks again for your great work and happy new year.
Torben Posted Dec 31, 2021 3:50 AM PST
Big thanks for a great review ... confirming my purchase and just eager to receive it! On a sidenote I consider this projector somewhat unique in its ability to throw a 100" size screen at a fairly short distance. Actually; according to your current database listing, UHZ50 is the new leader of the pack among standard throw projectors. UST projectors are of course capable within this area, but if you have a center speaker, they do tend to steal the space below the screen ;-)
Cory Posted Dec 31, 2021 4:31 AM PST
Hey there John, Thanks for the review…could you comment on apparent sharpness and black level? Being laser and modulating blacks Is it a cut above other DLPs for blacks? Is sharpness on par with other 4K-pixel shifting DLP? Also, did you notice if the projector did any brightness matching or dynamic tone mapping in HDR modes?

Thanks, Cory
Martin Posted Jan 3, 2022 3:27 AM PST
@Peter Yes there is light border around picture approx. 1-2 inches - depends on the size of the image (DMD chip 0.47 second version) There is more rainbow effect than UHD30. I had UHD42 (UHD50x) and I din´t see any RBE there. But UHZ50 has a very visible RBE.
Arun Posted Jan 5, 2022 6:14 AM PST
Great review! I know the following projectors are in different leagues , but how the black levels of this projector stands against ls500 Epson short throw projector. I am from India and ls500 should not be too expensive than uhz50 .
Rob Sabin, Editor Posted Jan 5, 2022 7:53 AM PST
Two very different animals and I feel certain saying that blacks and contrast on the UHZ50 should be better. The LS500 is really designed for brightness and suffers from relatively high blacks and mediocre but acceptable contrast for dark room viewing.
Tony Posted Jan 6, 2022 12:48 PM PST
Hey Rob, thanks for the short comparison between LS500 and UHZ50. Will you do a video review for this UHZ50?
Rob Sabin, Editor Posted Jan 6, 2022 12:50 PM PST
I hope to while it is still in our possession based on the high interest in this model.
Mack Posted Jan 8, 2022 5:47 AM PST
@ Martin sir, we are both alike.. I own the uhd42 and was thinking to grade to the uhz50, Thank god I read your comment. im so disappointed with optoma, they should of work on the uhz 65 making it smaller, better latency, less heavy, and low price, and even 240 hz or 2.1 Port with 4k 120hz if you look at the reviews, the picture quality is crazy good better then epson 3 lcd. Let me know whats your next move?
Adam Posted Jan 12, 2022 3:41 PM PST
Excellent detail in this review! Thanks for explaining what changes happen when switching to various gaming modes and 120hz. I'm definitely lusting for a 4k 120hz projector, but I think it's time to settle for this one that can do 4k HDR at 1 frame of latency while gaming. I especially like the standard throw distance with adjustable vertical shift.

Simple query - how do the black levels compare to the Epson 5050UB ?? (or JVC N7 - wishful thinking :) ).

l find black levels very important in a projector, not overly clear in the review.

Putt Posted Jan 14, 2022 2:14 PM PST
As other's have mentioned i'm curious on your thoughts of this vs epson 5050ub? Certainly 2 different main use cases but laser is very tempting looking!
Rob Sabin, Editor Posted Jan 14, 2022 2:19 PM PST
Two different animals, to be sure. I haven't seen these side by side and haven't had a chance yet to look at the UHZ50 at all, but I'm willing to venture that the 5050UB is in a different class in terms of dark room home theater reproduction. Of course, you are giving up the laser for a lamp, but gaining a bigger/better lens that is motorized, and Epson's UltraBlack contrast-enhancing technology. You also get the benefit of a three-chip design and its equal color and white brightness, as well as immunity to rainbow artifacts. On the other hand, the UHZ50 is by far the more serious gaming rig.
John Posted Jan 18, 2022 11:20 AM PST
Rob, do you have any advice for people considering the UHZ50 vs. the LG HU810PW? Video games are only a minor consideration for me. I'd be replacing a 10yr old Panasonic 55" plasma TV w/ support for 3-D playback. Since the UHZ50 supports 3-D, that's interesting to me (aside from 3-D Blu-Ray discs we have a Sony 3-D video camera). But overall, I won't buy based solely on 3-D support. If there's a significant gap in image quality, then I would still favor the better image. So, I guess I'm asking for a qualitative statement about how the UHZ50 and HU810PW compare in that regard.
Rob Sabin, Editor Posted Jan 18, 2022 12:59 PM PST
John, I haven't seen the UHZ50 yet but my gut is that the HU810 is the more sophisticated in terms of its picture adjustments and the ability to get a finely tuned image from it. I'm guessing it also has the better HDR and the ability to get deeper blacks in a dark environment from a DLP engine by virtue of its manual iris that offers a wide range for light output. If neither gaming nor 3D are dealbreakers for you, my gut says the HU810 is the better play if you're really serious about image quality. That said, I'd recommend getting on the user group boards for these two at AVS forum and see what folks have to say about their experience with these two so far.

Speaking of laser projectors for gamers and theater enthusiasts, any idea when you'll have a review sample of the Espon LS12000B? Seems like the first 4k Epson and first projector with HDMI 2.1 for 4k 120hz gaming with usable lumens in 5k and under price, but no announcement for US release yet.
Alexander Posted Feb 1, 2022 1:24 PM PST
Thanks for the great review. A few questions: 1. Wats the color wheel segment RGBRGB or RGBWRGBW ? 2.% REC.709 and DCI-P3. I will wait for your recommendations for color settings in HDR mode for watching movies in the most dark room.
Kelmin Posted Feb 14, 2022 6:06 PM PST
Thank you for the detailed review. I would like to request an opinion if I may. I currently have an Optoma UHD60. I will be moving my setup into a dedicated home theater in a basement that will be completely blacked out with no windows. I will be using a 175” screen. Would you go with the UHZ50 (or another option that I may not be aware of) or should I just stick with the UHD60? This will be a dedicated theater room for just occasional movie and sports viewing. Your reply will be greatly appreciated.
Alain Posted Apr 26, 2022 4:53 AM PST
Hello, Thank you for your excellent tests. I would like to know if we can adjust the parameters for each image preset, or is there only one user memory please. Cordially. Alain
Rob Sabin, Editor Posted Apr 26, 2022 2:02 PM PST
Virtually all Optoma projectors will retain changes to their preset memories, so you can tune the individual color modes as well as create your own if a User memory is available.
Alain Posted Apr 27, 2022 12:36 AM PST
Hello, Thank you very much Rob for your answer. Have a good day. Cordially. Alain
Sipu Posted May 27, 2022 6:29 AM PST
In the 3D mode the image blacks go really green and i can't seem to fix that in any way. In practice this makes the 3D mode unusable for me. Is this something you encountered or is there some issue with my Unit?
Keith Posted Jun 14, 2022 2:56 PM PST
I'm on the verge of buying this projector but am trying to figure out what kind of screen I should get. It'll be in a light-controlled theater with dark red walls and ceiling. I built my previous screen to save money and have been happy with it, but I'd like to know the best kind of screen material to replace the old white screen with. Any suggestions on gain, etc., would be appreciated.
Rob Sabin, Editor Posted Jun 14, 2022 2:59 PM PST
Keith, you didn't say what size but it sounds like a standard matte white 1.3 gain material will probably work great, providing a bit of extra brightness for some pop with HDR even in the dark room. Elite makes a very affordable ISF certified material, the CineWhite UHD-B, which we've been using successfully in our video studio. Great value if you're not looking to spend a ton.
Sam Posted Aug 21, 2022 1:22 AM PST
I was using the sony KD65Z9D which is an exclusive model of sony the last made 3D TV with 4k high picture quality, I want another big screen tv so I was in search of it. And I came across this projector, I bought it without confidence, I thought it can't compete with my old sony tv. but I was wrong, this projector, I first connected with the Nvidia shield and the picture quality was not up to mark and I was not running any plex server nor heavy gamer. so I replaced the Nvidia pro shield with my fire cube which is a dedicated streaming device, everything changed after that. the picture is crystal clear, HDR was amazing, fast reboot. everything is perfect so far I have kept HDR always in my fire cube display settings which works really well with this projector. until the next native 4k projector price comes down I will use this .it keeps everyone satisfied from kids to old people .. sorry for my bad English.
Zygis Posted Sep 2, 2022 3:15 AM PST
Hi! decided to get either Optoma UHZ50 or LG HU810PW. Would be more than thankful for an advise which is better all rounder for a day and evening use in different lightning conditions. They are similarly priced and specifications are also similar.
Zygis Posted Sep 14, 2022 2:19 AM PST
Just purchased and tested Optoma UHZ50. Overall - very happy with the results. For my usage i see improvement over my older Epson Eh-tw7000 aka HC3200 3 LCD projector. What i like: day-night difference in sharpness and details of laser DLP. Epson looks blurry and acient in comparison. The colors are not as vivid, but very natural and easy on the eyes (cinema mode or User). It's very watchabe with ambient light. Throw ratio suits my distance better. Conrast is quite good for DLP, but i use RGB mode 16-236 which makes colors and contrast look much better. I also prefer it over my Xiaomi 4k 150 UST projector which is also laser DLP (and have amazing soundbar integrated). What i dislike about Optoma UHZ50: The home meniu and downloadable apps are unusable - navigation through them is as terrible and frustrating as it can be. Forget proper navigation through netflix or youtube apps. The internal speakers are so bad, they should have not put them in the first place. Some smartphones have better speakers.The remote control is super cheap, but compact and decent design. It works only when you near and pointing directly to the projector. So my overall experience is quite good with visuals, and quite bad with all the additional features. P.s i do not use HDR so did not comment on that. if you need smart projector with all-in one features definetly look elswhere, but for home ceiling mounted gaming/cinema projector i think its one of the best options outhere. Hope this helps a little bit someone.
Rob Sabin, Editor Posted Sep 14, 2022 7:58 AM PST
Great comments, Zygis -- thanks for sharing with the group.
Dave Posted Sep 20, 2022 12:43 PM PST
Great review! How much of an improvement would this be if I'm upgrading from a UHD60?
Liam Posted Jan 18, 2023 6:43 AM PST
Would love your advice . I have the epson 3800 and the uhz50 is making me pull the trigger as amazon has it for less than 2k. Would you choose the uhz50 over the 3800 in terms of contrast and picture quality. I don't care too much about gaming. I'm looking for something that is better than the 3800 under $2500 laser and 4k pixel shifting
Kct2 Posted Feb 12, 2023 8:04 AM PST
Would this be a significant upgrade over the Uhd50x? I have a few issues with my current 50x, the split screen issue, very slow HDMI sync on input mode changes, and bad banding with HDR content, which I've only been able to solve by turning off HDR on the projector. Does the UHZ50 suffer from any of these issues, and have improved picture quality?
Jim Posted Mar 7, 2023 8:51 AM PST
i cant seem to get decent black levels without turning dynamic black on even on low brightness setting though mine is the uhz45 anyone have this problem on the uhz50 am getting an nd filter hopefully that will fix it
Robert Posted Mar 12, 2023 10:17 AM PST
A question for John: It appears that you used Cinema for your calibration; if your adjustments are input into User, will the resulting picture be the same? Also did you measure nits when finished? I have a Panasonic UB820 and would like to know if the 820 'Projector' setting for UHD is appropriate or if this projector is brighter due to the laser etc.

John Ross Posted Apr 17, 2023 6:35 AM PST
Hi, Do we know the speed of the wi-fi on the UHZ50 as I am wondering if it would be better to run a cat8e cable from it or just stick with the wi-fi, My isp is FTTP and therefore 1000mbps
Rob Sabin, Editor Posted Apr 17, 2023 8:37 AM PST
We do not know the speed, John. You might find it in the manual or specs which are available for download on our UHZ50 database page.
Jon Anderson Posted May 4, 2023 11:16 AM PST
I bought this projector based on Projector Central's great review and detailed information. I just had a brief call with Optoma technical support after learning how loud high elevation mode was. In my test, sound levels went from 35dB to 65dB and it's on constantly. It's essentially unusable at that noise level in my room.

The rep I talked with said it had to be on all the time in Colorado and that's just the way it is. It felt like he was just looking to get off the phone and was basically asking why that noise level was a problem for me ("Do you hear it during loud action scenes?").

It may be that I get comfortable without running high elevation mode and supplement air flow around the projector in other ways, but I'm soured on my customer service experience with Optoma.
Pedram Posted May 7, 2023 11:58 AM PST
After reading this read this mostly positive review, and given my great experience with my Optoma HD33, I pulled the trigger and bought this.

While it has some nice visuals and bright, sharp picture, there are some definite drawbacks and problems. -Focus uniformity issues on things with sharp detail (e.g. menu screens, PC input). Optoma says that's "in spec" and refuses to do anything about it. -PureMotion frame interpolation doesn't work properly. It doesn't activate on 2D or 3D content, even though the projector says it's on. The only way I could get it to work is to force 24Hz output on my playback device, but when it does kick in, the sound and image are noticeably out of sync. I confirmed this with another owner of the projector -If you watch 3D converted from a side by side 2D image, the sound is way off.

These are deal breakers for me, and I returned the projector. Unfortunately, there isn't currently another 4k laser projector with similar brightness and 3D support anywhere near this price range.
Fargeot Alain Posted Sep 4, 2023 7:01 AM PST
Good morning, Question to users: Can we enter 3D on the HDMI3 socket please or do we have to unplug each time and put on HDMI2. Thanks in advance for your help. Sincerely ---------------------------------- Bonjour, Question aux utilisateurs : Est-ce que on peut entrer en 3D sur la prise HDMI3 s'il vous plait ou faut-il débrancher à chaque fois et mettre sur HDMI2. Par avance, merci pour votre aide. Cordialement
Jay Posted Oct 2, 2023 9:29 PM PST
I know this review is pretty old but I just wanted to say thanks for the great review and the calibration settings. I had already decided to purchase this unit, but was looking for a good baseline for the picture settings. Yours work perfectly with my setup and the image looks amazing. Your review definitely made me comfortable with my decision. Thanks for the great advice!
Rob Sabin, Editor Posted Oct 3, 2023 9:31 AM PST
Thanks for the encouraging words and glad it worked out for you, Jay.
sanjeev Posted Apr 2, 2024 8:38 AM PST
Hi Rob Amazing review of the product. I bought UHZ50..I have white ceiling and Magnolia walls,mostly watch in the Night.Optoma says 3000 lumens which is not true.Should I go for Cinegrey 3D with 1.2 gain Or Vividstorm 0.8 Gain Alr Obsidian black screen.Your help will be greatly appreciated.Thanks
Rob Sabin, Editor Posted Apr 2, 2024 8:43 AM PST
Sanjeev, we measured only 2500 lumens in Bright mode and approximately 1,000 - 1200 lumens in the more accurate Reference and Cinema modes. Game mode was around 1,700 lumens.

You didn't say how large your screen is, how dark your room is when viewing at night, and whether at your current screen size you feel like you're getting enough punch with movie content. If you don't feel like its bright enough, the 1.2 gain will help. If you're looking for deeper blacks and better contrast, the 0.8 gain is the better choice.

I suggest you pose the question on our Facebook User Group forum, where other members can help you make a more informed choice.

sanjeev Posted Apr 4, 2024 5:36 AM PST
Hi Rob,Thanks for your quick response. I am looking for 135 inch screen and the Room is dark in Night but have Magnolia walls and white ceiling. In my projector setting I have set the HDR mode and not SDR mode so how many lumens are there in HDR mode and 1.2 or 0.8 which you think is better.I am also putting this to Facebook group
sanjeev Posted Apr 5, 2024 7:07 AM PST
Hi Rob Thanks for your explanatory reply.I am looking 135 inch screen and projector is set on HDR and not SDR as SDR you can change different modes .I dont know how much lumens are on HDR settings.Please share. as per your advice I did put on Facebook group
