Ignore manufacturer’s claims for contrast. They are all 100% Grade A baloney.
Both the Epson and Optoma use pixel shifting to achieve their max resolution. The Epson is a native 1080p device (2m pixels) that doubles it’s resolution to around 4 million pixels— sharp but still half the resolution required to classify as ‘4K’. The Optoma, on the other hand, starts with a custom resolution of 2716x1528 (4m pixels) and doubles that to the full 8 million pixels to classify as 4K. So the Optoma will be noticeably sharper— depending on your screen size and viewing distance of course. The Epson compensates by throwing everything but the kitchen sink into the features list. In addition to the motorized lens and generous shift range it also has lens memory, CFI (but only for 1080p content), an auto iris to improve blacks, 3D compatibility, and a filter to improve DCI-P3 coverage. It also has fairly low input latency around 30ms. Strangely, it LACKS a full bandwidth HDMI so 4K/60 is not possible— perhaps an admission that this isn’t really a 4K projector on any sense of the word. The Optoma does have a full bandwidth HDMI but the one thing you’d want to use it for, gaming, is hampered by a rather mediocre input lag of around 56ms.
Both are big, both are relatively quiet, both are bright although the Epson measures a bit brighter despite it’s lower lumen rating— there’s those pesky made up numbers again.
If you want 4K, like actual 4K, the Optoma is the better choice. Conversely, if you want a really well equipped projector and you don’t mind sacrificing some resolution to get it then Epson is a great choice.
Thanks for the input. The current latency on my Mitsubishi is about the same on the Optoma, and for the XBOX games I play, I have not noticed it enough to affect any of my game play, even on faster first person shooters. I do agree I think the Optoma has a better starting point.

The things I took from the review were:
"The Epson HC 4000, while competitive in HDR, has a definite advantage in SDR." "So in the end, the picture for most 1080p sources tends to be brighter, cleaner, and higher in contrast on the HC 4000"
For HDR, " In general, on an image with a range of elements from dark areas to bright highlights, the two projectors typically show very similar contrast. They can actually switch back and forth as to which is the higher in contrast within a given scene."
"Certainly the difference in image resolution of a 4K source is insignificant, and far less than you'd expect from the two different light engine technologies."
If you read the comment section on the review as well, I noticed, "My major concern with your review is lack of color gamut and color accuracy info in either SDR or HDR modes. Assuming you didn't test either based on your comment. Why isn't the smaller REC.709 gamut of the UHD60 (which can ONLY be achieved 100% in its dimmest Reference mode) a negative factor for the UHD60 compared to the +100% DCI-P3 ultra wide gamut achievable in the HC4000 in its Cinema and Digital Cinema modes? (Based on my CalMAN 5 gamut tests using an XRITE i1 Pro spectrophotometer.) To most viewers, color saturation, accuracy, and contrast make a bigger impression than the minor differences between these two in resolution--and it's hard to miss the advantage shown by the Epson's +100% DCI-P3 gamut coverage."
For 2/3rds the cost of a UHD60, with some trade offs, it appears to me the Epson is a much higher end projector. For even better contrast the 5040UB is available at the high end of your price range as well. I think that one is more comparable to the Optoma UHD65.
I am not an expert, just been looking into a replacement for my W1070 the last month or so before picking up a UHD50. I am very limited by my mounting location, so not a lot of choices. Just enjoy talking about it at the moment and haven't read the forums on these particular projectors. So just bringing up thoughts and not looking for argument and definitely don't know if I am right!
From my looking for deals over the last month or so, if I could have fit it in my installation at a bit over your price range, I would have gone for a Benq LED HT9050 that was selling refurb for $2400 last month. That is a $9K projector. It doesn't do HDR, but I think HDR for projectors isn't that big of a deal. Like with TVs, HDR doesn't make a difference unless a TV has high enough brightness, projectors aren't that bright to begin with, so my thought is I would have gone for better quality SDR over HDR support.
Cheers and happy hunting!
You bring up some good points. I do feel like the HC 4000 is a great camera it seems. I just dont believe it to be quite as good in the areas I am looking for compared to the UHD60. I have also looked at the UHD65 and the 5040UB. But both are really at the top end of my budget, and throw tax and shipping in there and its really more than I can afford to spend, which leads me back to the Optoma UHD60 for now.
If I had the budget, I would love to step up to the Sony 4k projector with wild reviews going for about $4,000, but its just not in my price range (or even close).
I think whatever I end up with, will in the end be leaps and bounds better than what I have now, and I am very excited for that given I still feel impressed at times with my ancient 1080p Mitsubishi.
