I purchased this through Visual Apex, because of stock issues with Amazon. VA is an Amazon merchant, so at least there's that. We purchased this to replace an aging Benq W1070.
The Projector is a little larger than expected, but size is not really an issue, and is clearly listed in the spec sheet. I ceiling mounted this with the Optoma OCM818W-RU mount, and mounting the projector only took a little effort. I highly recommend the Optoma mount. It is more expensive, but sturdy. It is much smaller than it seems in the picture. Mounting the projector only took minutes. The top cover on the projector is a bit flimsy and not up to the standards of a $2k item. Fit and finish here could be better.
I had read a bit about HDMI cables and the need to buy "good" ones for 4k, HDCP, etc., etc. I also read many articles claiming that HDMI is HDMI and any High Speed cable will do.
My issue was a 35 foot run from Onkyo TX-RZ800 to the projector. Our Benq worked fine with a 50' cable at 1080p, but I was aware that length could be an issue with 4k. I had bought the highest quality reasonably priced (Kolife) cable that was "high speed" rated, and said 4k, HDCP 2.2, 18ghz, 24ga, 4k@60. I was using a Sony UBP-X800 as the 4k source. I used the Optoma-supplied "high speed" HDMI cable going from the Sony to Onkyo. While I was able to see a 4k signal, I couldn't do so reliably. There were picture artifacts, flashes, dropped signals, and general poor image quality. I ran the long HDMI cable directly to the Sony and the issues got worse. So, the Onkyo was actually helping things. I also tried a signal booster at either end of the long HDMI run. That didn't work, either. As it turns out, HDMI is a poor platform for 4K@60. But, that's what we have.....
After doing some research and finding out that HDMI cables DO MATTER VERY MUCH when considering long runs and 4k@60, I bought the RUIPRO HDMI Fiber Cable 33 foot cable. The fiber optic solution fixed ALL signal drops, so we are in business. Any HDMI cable will not do the job, especially if you are going many feet. You absolutely need to spend the time to find the right solution to fit your budget and specific setup. Also remember that there is a difference in running 4k@60 vs 4k@30 or 24. You will experience more issues with inferior cables at the highest data rates. A cheap short cable may work for you, but absolutely did not for me. I highly recommend the fiber optic solution for long HDMI runs. The Ruipro seems to have great reviews and it worked wonders for my setup.
As for the projector itself, setup was a breeze. The large amount of zoom will help you find optimal placement in your space. This projector lacks keystone adjustment, so you'll have to have the vertical placement figured out. It does provide (15%?) vertical lens shift. The fan noise is moderate to low. I only notice it in a very quiet room. Even normal movie dialogue is enough to drown out the fan noise.
Images are stunning, to say the least! Fantastic colors, good blacks in a dark room. Sharpness that is hard to find anywhere at this price. For $2k, you get as big a screen as you can handle at home in fabulous 4K. Really amazing! Remember that this is a projector, though. It performs best in a darkened room, and will never be bright enough to compete against lots of ambient light. It is slightly brighter than the W1070. (3000 vs 2200 lumens). Movies, games, and TV are all great with this projector. I think the lag time is better than the Benq, because everything seems more synchronized, and gaming is great!
There are plenty of menu settings to play around with. I like Ultra Detail, but found that Dynamic Black seemed to add a little bit of noise to the image. The HDR setting seems to be the best (to my eye).
For me, this projector has a few minor drawbacks:
1- No keystone adjustment, placement must be planned. At least there's some vertical lens shift. Not a huge deal, but keystone is nice.
2- No 3D - For me this was no big whup. Our family decided 3D was more trouble than it was worth. Just be aware there's no 3D.
3- Limited to 8bit when running 4K@60. Must slow it down to 4k@24 or 30 to get 10bit and 12bit. Now, I'm no techie. I don't fully understand if this is a limitation of HDMI, the Projector, or what. I have seen some color banding in some images (gradient sky, etc.). I also don't know yet if this is cable related between the source and Onkyo. (better cables ordered). I can just see that color banding improves some when the feed is limited to 4k@24 and have read that color banding could be related to color depth. UPDATE: Better cables helped some of the color banding issue and it is far less noticeable.
4- This does not have an RGBRGB color wheel. It's RGBCY. For me, this makes the typical DLP rainbow effect a little more noticeable, but it does help provide the extra brightness. A tradeoff. I like the brighter image, so for me this is a good choice vs. the UHD65.
We have also added a 4K@60 Roku Ultra, and it is having the same signal drops using a 6ft "High speed 4K 2160p, 3D, 24awg, gold connector" cable (Farstrider). Based on the above experience and experimenting with several cables, I KNOW it's the cable, and have ordered replacements. Again, ANY cable won't do at 4k@60. The Roku Ultra is all 4k@60 all the time. I'll report back on the AudioQuest cables.
To sum up.... This is a great projector, and is the best deal on the market today. It does have some minor limitations. Also know that 4K@60 is not exactly "plug-and-play." You'll be buying some cables and doing some research.
UPDATE: The addition of 1m Audioquest Forest cables solved the issue of signal drops with the Roku Ultra. Using the AQ cables also seemed to improve the image coming from the Sony UBP-X800. There seems to be less color banding and dynamic range artifacts. They SEEM to make a big difference, but it is hard to quantify.
UPDATE AGAIN: After spending a month with this projector, I've decided that some of the image artifacts may relate to how the image was coded, as well as some of the conversions from SD to UHD. On the Sony UBP800, SD up-conversion gets set to 4K@24. If the source is at a higher frame rate, it passes through. The Roku Ultra is all-4k@60 all the time, and there's no way to change the Roku to a lower frame rate. Hence, there are still more image quality issues and dropped signals with the Roku. It's just flaky. As soon as I can get HBO and STarZ on the Sony, the Roku goes away! Image quality with the Sony Blu-ray is much better and much more reliable. There are still a few image artifacts that I can't explain, some slight color banding in some scenes, where other similar scenes are just fine. I'm beginning to believe it's mostly the fault of the source material? So far, the Optoma is working like a champ. The projector is still not quite as nice as a good 4k LCD TV or OLED, but the SIZE!!! This is still the best option for affordable 4K in a size where 4K matters.
Cost was just under $3100 AU from Amazon, inc import duties and expedited shipping.
My last projector was Epson 9100, which I am keeping for 3D playback. My set up is on a Carson mechanised 110 inch screen, casting from 3.6 meters. Feed content through Panasonic UHD 900, PS4 Pro, and Chromecast Ultra.
I bought the UHD60 as I use projector not in a bat cave, but in a room which is fairly light controlled, but with some ambient light leakage. Also gaming is important, so the 60 was for me.
Overall, EXTREMELY impressed with this unit. Though of course, not perfect.
• Regarding set up…you MUST be able to align in absolute centre of screen, at either very close to the top, or bottom of the screen. You can only lens shift to 15 Degrees, and ONLY upwards if you are throwing from below, or only downwards if from ceiling mount.
• No power cord problems, uses standard PC power cord, so just use an Aussie one. No voltage issues.
• As everyone has noted, unit build is a bit crappy / plastic…but aesthetic I think is pretty good. All controls re lens are manual.
• Big tip…important how you get content to it – I re did my set up to have my Pana UHD 900 close to the unit, as well as my PS4..so Ididnt need to pay out hundreds for fibre HDMI leads.
• I also have the Sammy UHD 8500, and that was useless compared to the quality and control I got out of the Pana UHD 900 on the Optoma. NIGHT and DAY difference. PS4 Pro gaming works a treat, gets full HDR etc compatability in the video settings. Gaming in 4K is amazing on the Optoma. Wipeout, Horizon Dawn, Uncharted etc are just awesome, and lag is not an issue. However, video feeds from the PS4 are pretty crap, eg Netflix, Stan, Plex. If you can , get your video feeds from a dedicated player, as I have said, especially the Pana UHD 900. On that unit, Netflix 4k / HDR looks fantastic. It doesn’t have Plex, so I use Plex via Chromecast Ultra for 1080p files, which looks great, even though the HDMI 1.4 port. Plex on the PS4 Pro looked like arse. Seriously.
• Optoma upscales 1080p files and Blurays like a treat. Very impressed.
• I have NOT professionally calibrated.
• Optoma resolution is just great, so happy with it. 4K really is razor sharp, of course, blacks could be better. But by no means a dealbreaker, depending on how fussy you are. BIG TIP – use DYNAMIC BLACK…it really works well. And be prepared to spend some time trawling the forums for getting tweaks for diff types of content re settings, it really helps. When you are experimenting, pay close attention to colour gamut, as well as Gamma presets, they make a BIG difference.
• HDR generally works surprisingly well..especially with gaming, and my fave UHD discs, depending on the source material. Big tip here…if on a UHD disc source, HDR looks dodgy…strip HDR from the source player (Pana does it) and get straight 4K out put..solves a lot of problems. For example, the new Prometheus UHD look GREAT in full 4k / HDR…better than I was even hoping for. But…Alien Covenant…seems they somehow screwed the HDR on that, so I strip the HDR from it, to just 4K output, and it looks fantastic.
Overall, I am extremely impressed with this Optoma. As has been well reported, if you don’t care about gaming and want better blacks, go the UHD65. But either way…for this amount of money compared to the competition, I reckon Optoma have really hit it out of the park. I’m planning on keeping it almost as a stop gap for a couple years, till someone makes a great 4K native player that also does great 3D, and does not cost over ten grand. Like I said, I’m no expert, but hope this info has helped. Cheers
