I am returning it ASAP!!

I am returning it ASAP!!
2. Projector is everything as advertised and more
3. HDR does work passing through my reciever (might be different for others) needed to connect to the input connection closest to the output connection on the reciever
4. Mounted to ceiling projecting to a 91 inch screen important to mount within the advised distance to get flexibility with focus
5. Only "bad" thing about this projector is when it auto switches from SDR to HDR there is a delay as the projector recalibrated itself
6. For firmware updates, the provided dongle needs to be in a different usb port than the Alexa port...but I don't use Alexa so its not been a problem
7. The remote must have been updated for my unit as it's black and the buttons are back lit
8. Finally when configuring the colour it would have been nice if the menu stayed open a tad longer
I never trust to buy from Amazon online specially from Optoma
Top reviews from other countries
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.
3D - works
HDR - works
4K - works
Picture quality - looks great to me...
- in a totally dark room, I wish the blacks were more, well, black. even with HRD. they are good, but I wish it was darker on the darks. brightness is amazing (I have a fully windowless room in the basement)
- takes time to warmup
- alexa connection is a hassle (optoma's fault) their mobile app is terrible, but managed to get it done. Not very useful, since I have Harmony.
- Fire TV Cube doesn't recognize it...
- When switching between regular 4k and HDR 4k, it takes a couple of seconds
- I think I bought the official mount for it, and was surprised it doesn't support up/down. sadly after I installed the screen already... I had to go through weird workarounds to add that half inch of a tilt down... (the angle button didn't get far enough)
Other than that, very happy... but I'm not a projector expert.
Next I set up Alexa, it was a lot of steps but was pretty simple to setup. I was able to turn the projector off with my voice command once. After that it never worked again. Alexa would always say "living room not responding." This wasn't that big of a deal since I probably wouldn't use that feature too much. However, they are charging you for it so it should work.
The image was amazing, even with ambient light on in the room, there was great contrast, colors didn't get washed out. I was very impressed. I watch some Youtube 4K videos. Everything looked great until I started to watch movies.
Enter the rainbow:
I first noticed it on subtitles, reading subtitles then looking up at the picture I noticed rainbows. Especially with dark screens. Coming from a 3lcd protector I never saw a rainbow effect, so I thought is was just some strange artifacts happening with subtitles. Then I watched an episode of Gunpowder on HBO and there were rainbows everywhere. I threw in a bluray of Life of Pi and more rainbows.
Reluctantly, I packed up the UHD51a and started my refund on Amazon. I'll be dropping it off tomorrow. I'm pretty disappointed. I really liked everything about this projector. If you don't mind or see the rainbow effect then the image is beautiful, bright, and it is very quite. The Benq HT 2550, supposedly has a faster color wheel and from what I have read there is no rainbow effect. I do not believe that only 5% of people see the rainbow effect. My girlfriend said she couldn't see it but it was very prevalent to me.
Here's what earned the extra star: The Alexa connection didn't work when I got it and I called support and got a US-based person on the phone. He worked the problem with me and issued an RMA. He followed-up with me quickly and answered his phone or got back to me ASAP. I went to a local Optoma location and he personally came down and exchanged it. This is so far from my normal consumer support experience that I felt I should add a star.
