    • Happy with this projector. Finally, a 4K projector that checks all the boxes for well under $2K.
Style: 2400 lumens/2018 Model Pattern: Single
I ordered this projector a few weeks ago and dropped it into my system. I was excited because this was the first projector to come to market that checks all the boxes for under $2,000. RGBRGB color wheel for accurate color reproduction? Check. Support for HDMI 2.0 / HDCP 2.2? Check. Support for viewing 3D Blu-ray content? Check. Enough brightness to use outside of a bat cave? Check. So finally, 4K arrived in my home theater. The first thing I observed is that it does have a fairly short throw and only a small degree of lens shift, so you will either have to ceiling-mount or coffee table mount. Focus is manual. No motorized "lens memory" features for fans of 2.35:1 constant image height setups. Shelf mounting at the back of the room is not likely to work in most installations. This projector uses the 0.47" DLP chip with pixel-shifting. However, pixels do not appear to overlap when viewed up close - you can actually see the "screen door" effect if you put your face right up next to the screen. Unlike in the days of 720p projectors, no screen door effect is visible at normal viewing distances. Seeing the "screen door" up close is desirable - it means pixel-shifting DLP works and can reproduce a true 3840x2160 image, in which every pixel is individually distinguishable. It also means the optics of the lens are good enough to render high-resolution images. After using a Panasonic PT-3000AU 3LCD projector for the last decade, this projector was a big upgrade. It throws a brighter, more vibrant image on my 120" screen. While no lamp-based projector can fully reproduce HDR content, I can say that 4K HDR content is noticeably clearer with more vibrant colors. The expanded color space of 4K HDR also made for very smooth gradients, with considerably less "banding" artifacts compared to 1080p Blu-ray on my old projector. The UHD51A uses an RGBRGB color wheel, which is best for home theater applications as it renders colors most accurately. Competing models that have higher lumen ratings (high 2000s to mid 3000s) use an RGBW wheel, but that extra brightness is lost when the projector is calibrated for accurate color reproduction. The RGBW wheel gives extra white lumens that can cut through ambient light, but I found the UHD51A's RGBRGB wheel to be bright enough to illuminate a 120" 1.1-gain screen in my living room, which is not totally light-controlled. HDR is not rendered as well as on an OLED TV, but those are prohibitively expensive if you want a picture size over 65". The visual impact of a 120" picture is considerable. Black levels are not state of the art, but they are good enough. It's comparable to what you would experience if you went to a movie theater with digital projection. Projector users are familiar with these compromises; that aspect has not changed in the last decade. Like all the 0.47" DLPs on the market, this projector does have a "light border" that extends past the picture area, and even past the black borders on my screen. If this bothers you, paint your screen wall a flat black to reduce this effect. I do wish TI would fix this in the 0.47" DLP light engine. A projector should not project light outside the borders of the image. But again, all 0.47" DLPs have this issue currently, so consider it when setting up your theater. I didn't set up the Amazon Alexa features so can't comment on those. Also haven't tried 3D yet, but am looking forward to watching a 3D movie on a 120" screen. This review may seem negative, as I pointed out some caveats and limitations. It's important to take these issues into account, and this projector may not work in every room. I did have to re-arrange my room to get this projector into my system, but it was worth the trouble. No one else offers a 4K + 3D projector for well under $2,000. It has given my theater a considerable boost in picture quality, and I finally get to enjoy 4K content the way it was meant to be seen. If, like me, you want both 4K UHD and 3D, this is the best bargain going currently. ... show more

    • Absolutely stunning 3D
Style: 3000 lumens/2018 Model, Brighter output Pattern: Single
I have been observing carefully the 4k projector progression for years, hoping to have: 1) reasonable price (below $2,000); an enhancement of the 2K quality of 3D 1080Px2 by regards to its increased pixel projection; and 3) enhancement of the irritating 1/2 decrease in illumination of 3D versus a 2D projection. With the Optoma UHD51ALV 4K unit I received and set up yesterday, I'm delighted to say I've gotten all of that (plus of course 4K flat projection as a viewing option for UHD blu rays). 3D from this unit (projecting and viewing several different 3D discs) was absolutely stunning: (compared to my prior faithful workhorse, BenQ W1070 1080P 3D Home Theater Projector) the 1080P is more detailed, the colors more vibrant, and the picture brighter, up to a normal viewing level (versus the dusky 3D of the Benq that ones eyes would have to adjust down to). My faithul (now retired) BenQ was 2,000 lumens and this unit is 3,000 lumens, giving me a very significant increase in brightness without washing out any colors (as happens if one just tries to brighten up an image on its own). I directly compared 4K to 3D on this unit using the picture "India" that's provided as both 4K and 3D in the same offering. 4K on this unit is spectacular, with amazing crispness and detail in the smallest features. The 2K of the 3D rendering is a bit less crisp and detailed in the small features compared to the 4K, but still superior to what I've previously viewed from 1080P discs. What with the increased (to normal viewing levels) brightness while maintaining vibrant colors, the 3D from this projector is nothing less than stunning. For instance in the India documentary versus the spectacular 4K details, the 3D surrounds you and pulls you into the depths of the picture, as close to looking through a magic window at the real thing as you can get (versus seeing a flat, wonderful rendering of reality in 4K). So my point is that though this is rightly touted as an excellent 4K projector, it's ALSO a fabulous 3D projector for those of us with two working eyeballs that savor such renderings. Also please note that you need not freak out (as I almost did) when initially exploring the settings I found the 3D options missing or grayed and unresponsive. After my long search and laying down nearly $2,000 to buy this thing I had the terrible thought that I'd been sent the wrong model, one that only did 4K not 3D. But, fortunately, I decided to slap in a 3D disc and was delighted when the projector recognized the format and lit up the 3D settings for usage. Whew! Anywho, the only thing that would make this unit better is if it could render (nonexistant) 4K 3D as 8K. Actually, that's not so fantastic as I read 8K TV's are right around the corner, making it quite feasible to view a 4Kx2 3D disc! Hey, you tech geniuses, don't forget us 3D nuts! And thanks to Optoma for not leaving us behind, but giving us an even better experience as the world moves to 4K. Well done! ... show more

    • Faulty unit
Style: 2400 lumens/2018 Model Pattern: Single
Update 2: after the second day this unit seems to be faulty. The picture is now blurry and grainy and there is often a line down the middle of the screen, with one half of the screen darker than the other. 4k material looks worse than 1080p now. I've tried adjusting every setting and it still looks terrible. Amazon suggested I return it. Update: I'm changing my review from 1 star to 4 after the projector suddenly decided to accept a 4k signal after no changes. The setup was a bit of a nightmare, but now it's working on the second day. As far as the picture goes, it's crisp and clear. I notice the rainbow effect only slightly and not very often. The sharpness could be better, but overall it's a huge step up from my old 1080P projector. Alexa is still not working and I have given up on setting that up for now, but using a voice command to turn it on is that not that big a deal as using the remote is just as fast. My biggest complaint is the lack of ARC. Previous review: will not accept any 4k signals. I've tried different cables, different devices, every possible setting and it still won't work. It starts to play a movie then says no signal. What a huge disappointment. ... show more
