Sub-$700 Home Theater Shootout

This review of the Optoma HD143X is the first of eight reviews of 1080p home theater projectors priced under $700 that will be posted over the coming week. The projectors in this group review will include the BenQ HT1070A, the Epson Home Cinema 1060, three models from Optoma, the HD143x, HD27e, and HD29Darbee, and three models from ViewSonic, the PJD7720HD, the PJD7828HDL, and the Pro7827HD. The specs and prices of all of these models can be seen here: Sub-$700 Home Theater Shootout


At just $549, the Optoma HD143X stands out as one of the less expensive of the eight projectors in our group review. And at that price it is an excellent value for its combination of contrast, three-dimensionality, minimal input lag for gaming, and solid 3D performance. In addition, like many Optoma projectors, it also has the advantage of showing virtually no rainbow artifacts.

As you might expect from its slightly lower than typical lumen rating, the HD143X delivers a bit lower brightness than its competition with our video optimized settings as well. But the brightness is not enough lower to make a significant difference in acceptable image size for any given light level. Using the video optimized settings and a 1.3-gain screen, it is bright enough for a 145" 16:9 image in a dark room or a 90" image with moderate ambient light.

Lab Tests: What the Meters Say

Brightness. The measured ANSI Lumens for each predefined color mode for the HD143X is as follows for both Bright and Eco power modes and with the lens at its widest angle setting:

Optoma HD143X ANSI Lumens


Low Lamp Mode. Eco mode is 63% as bright as Bright mode.

Video Optimized Lumens. For film and video, the easily tweaked Cinema mode offers neutral color with no loss of brightness. Image quality is also near the top of the sub-$700 pack for contrast and sense of depth, although a small step below the best. At 758 ANSI lumens, Cinema mode will light up a 145" diagonal 1.3 gain screen in a dark room. If you want to run with moderate ambient light in the room, we'd suggest keeping the screen size to 90".

Video Performance. Even without adjusting color control settings the Cinema and Reference modes deliver natural-looking color along with good contrast and sense of depth. If you need higher brightness, Bright mode is largely usable, with only a minor green bias in most scenes. However the green bias as well as some posterization becomes more noticeable in the flesh tones on facial close ups. Much the same is true for Vivid, but neither the posterization nor green bias is as extreme.

The Game mode is the brightest mode that delivers consistently realistic color. It doesn't offer the image three-dimensionality and contrast of Cinema mode, but the picture quality is good enough for casual daytime use when you need the extra brightness to compensate for ambient light.

Zoom Lens Effect on Brightness. With only a 1.1x zoom, there is no curtailing of light at the telephoto end of the lens.

Brightness Uniformity. The measured 38% brightness uniformity for the HD143X is unusually low and enough to see easily with static images like a Windows desktop or a word processing document. The saving grace for video and film--and what keeps this from being distracting--is that the human eye tends to accept variations in brightness in photorealistic scenes as being part of the original image.

Input Lag. With Enhanced Gaming set to On, input lag measures a very quick 16.4 to 17.3 ms, depending on the Brilliant Color setting. With Enhanced Gaming Off, the lag measures a still fast 33 to 34 ms.

On-board audio. The 10-watt mono speaker delivers high enough volume for a small family room and distortion free sound quality even at top volume. If you want bigger sound, the stereo audio output will drive a sound bar or other external sound system.

Fan noise. The HD143X's fan noise is typical in our group of eight sub-$700 1080p projectors. Bright mode is loud enough to notice in quiet moments in a family room. Eco mode is quiet enough so few would notice it in a family room with ambient noise, but might notice it in a quiet room. The sound quality in both is an unobtrusive steady white noise. High altitude mode is also typical: loud enough in both Bright and Eco modes to be potentially intrusive in quiet moments, even in a family room with ambient noise.

Setting up the Optoma HD143X

Connection Panel Inputs:

  • (2) HDMI 1.4a, 1 with MHL
  • (1) USB Type A (Power only)
  • (1) VESA 3D Sync
  • (1) 12v out
  • (1) 3.5mm stereo audio out

All connectors are on the back panel.

Throw distance. The throw distance for a 120" 16:9 diagonal image with the 1.1x zoom lens ranges from about 12.8 to 14.1 feet. The Optoma HD143X Projection Calculator will let you find the throw distance required for the screen size you want.

Lens offset. The HD143X's lens offset is designed for either mounting upside down in a ceiling mount or placement on a low table or bookshelf behind the seating area. A high shelf is best avoided because the entire image would be above the center line of the lens. Setup would require tilting the projector down and then squaring it up with keystone adjustment. This is something we try to avoid with 1080p projectors as it requires compression of 1080p video signals, reduces lumen output to some degree, and can create artifacts in fine detailed patterns in an image.

With the projector on a table, the bottom of the image is about 14% of the image height above the center line of the lens.

Our Take on the Optoma HD143X

The Optoma HD143X offers more than enough to qualify as a solid value for $549. It delivers good image quality for the price, it displays 3D well, and it is bright enough for a 145" 16:9 image in a dark room or a 90" image with typical night-time levels of ambient light in a family room.

If you are into serious gaming, the HD143X's very quick 16.4 ms input lag makes it a good choice for games where reaction time matters, although it would be even better for gaming if its onboard audio offered a higher volume.

With its video optimized settings for 2D, the HD143X offers suitably neutral color, good contrast, and a good sense of depth. It also shows rainbow artifacts so rarely that even those who see them easily may not notice any, much less find them annoying. For 3D, it supports both DLP-Link and VESA RF glasses; its 3D mode shows only the typical drop in brightness compared to its 2D modes; and unlike many projectors, it will let you customize the 3D mode settings.

Optoma HD143X Home Theater Projector

The 38% brightness uniformity is surprisingly low. However, the eye tends to interpret brightness variations in movies as part of the original image and adapts to any variations it notices quickly.

On the plus side, the lens delivers crisp, edge-to-edge focus. On both our horizontal and vertical test images, with alternating one-pixel wide light and dark lines, it held the lines across the entire screen from top to bottom and left to right. Images with repeating patterns were also equally crisp over the entire screen.

The Optoma HD143X isn't quite as bright as its most direct competition, but the difference isn't much. In exchange, it costs less than most, it delivers natural-looking color along with good contrast and depth for the price, it offers a fast lag time, and it handles 3D better than most. This combination lets it do a pretty good job for games or as a TV substitute. However the audio volume is lower than competing models as is the brightness of the video optimized picture. These two factors keep it from being a top pick for either gaming or TV substitute. BUT...if you already have an external sound system and won't be relying on the projector's audio, the HD143X would be an outstanding choice for video gaming.

After seeing all of these eight projectors side by side, by comparison the Optoma HD143X handles 3D well, and for 2D it scores among the best in this roundup for color, contrast, focus, and three-dimensionality. All of that considered together, along with its aggressive price, is enough to outweigh its low brightness uniformity and easily make the Optoma HD143X one our top picks in the sub-$700 category for classic home theater in a dark room and for 3D.

I am really sorry but this is like a joke. how can you say 38 percent brightness uniformity as a small thing. there is simply no uniformity at all. it is a faulty projector and if the company is allowing that in their product lines it is more than a fault, it's unacceptable. you keep saying of human eyebcamt recognize that in a movie but trust me when I say this, my Benq has problem and it's always visible because one side of the screen no matter what it is brighter than the right side. it's in such harmony that brain can not not see any other way. So why not demand the company to fix the lens system..

Hayati: Without you having the unit I reviewed, or me having your unit to look at, it's impossible to know if we even disagree on what constitutes a problem. Yours may be objectively much worse than the test unit, with either a greater variation or a variation that changes more quickly over a shorter distance, which would make the problem a lot more obvious and lot harder to ignore.

Alternatively, you may simply have less tolerance for brightness variation than I do. As a general rule, most people will accomodate very quickly to a fairly large variation in brightness, but how much a given level of variation bothers you individually is a subjective matter and absolutely personal to you.

A similar situation applies to many other potential issues with projectors like rainbow artifacts and fan noise. The challenge for a reviewer with any issue like this is that any given reader may or may not notice the issue, and if they notice it, they may or may not find it bothersome.

Because the effect of these issues on viewing enjoyment is completely subjective, we at ProjectorCentral try to go beyond giving one person's opinion about how something looks or sounds, and add enough information into the review to let readers decide for themselves whether they agree. If I had said it looks fine without also giving the 38% brightness uniformity measurement, you'd have reason to complain. But you would have just as much reason to complain if I said everyone would find it distracting. Neither comment would be true. Given that the information in the review is enough to tell you that you disagree with my opinion, I submit that we've told you what you need to know to make a buying decision that's right for you. Ultimately, that's our goal in every review.

M. David thank you for explaining your reasoning. I appreciate that. Actually you are the only review site publish these numbers so the last thing I would want is to offend you in any way. from your point of view I agree with you. İt is informative and helpful to know. I care about fan noise and brightness uniformity, based on the numbers you provide I can make my up. So I guess I got hung up on wording about the uniformity but Ally least you are in the middle. saying good or bad would be wrong as many might not mind at all. So thank you again. and about my projector, it was like banding and shadows on the screen that seemed like big dark stains. so it wasn't gradual thing like these projectors. Thank you for your reviews

Thanks for a great review! Have You tried the HD144X? Brighter but in other respects the same?
Ben Dhir Posted Mar 3, 2019 9:20 AM PST
I've had this projector for a few days, the rainbow effect is terrible, even my 10 year old son said "daddy, why can I see rainbows" picture quality is good. But it's terribly annoying when a white part of a dark screen looks that bad.
Greg Spight Posted Jul 31, 2019 1:36 AM PST
This projector was rated pretty high so I gave it a try. Everything was good until I noticed a 4-5 inch shadow outside of my projector screen. After some research I found that this issue was called over spill. Even with black felt tape around my screen, the over spill was this visible. I called Optoma and they said this was a issue with this particular projector. I could not deal with the issue so I returned and got a BenQ MH535. Totally happy now. No over spill and has more Lumens
Satish Baniya Posted Dec 24, 2019 12:41 PM PST
How can I connect this projector with Home Theater sound system (Pioneer - 7.2-Ch. with Dolby Atmos 4K Ultra HD HDR Compatible A/V Home Theater Receiver)? There are 2 HDMI on the back of this projector - I'm using one for Firestick to play Netflix or HULU, and I'm hoping to connector second HDMI to my Home Theater receiver but it does not work. Any suggestions?
Rob Sabin, Editor Posted Dec 24, 2019 12:44 PM PST
Satish, the HDMI ports on this projector are strictly inputs for source components and cannot be used to feed sound back from the projector. In your case, since you have an A/V receiver, you would connect your Firestick to an HDMI input on your Pioneer receiver, and run an HDMI cable from the Monitor Out HDMI connection on the receiver to one of the HDMI inputs on the projector. You can also connect other HDMI sources, such as a cable set top box or videogame console, to the other available HDMI inputs on the Pioneer receiver. Then, you use your receiver to select the input you want to watch. The receiver will strip the sound off the signal from the Firestick or other component and send the video portion on to the projector.

great review - thanks! I setup the projector last night, it was very easy to get going. I found the fan noise loud, a little bit of googling, I found your site and it confirmed there was an eco mode. It took me a while to realize that you have to set eco mode with the remote control, not the on-screen menu. Now that it's done, the projector is working great. thanks!
