I connected fiber cable to A/V receiver and also directly to BD player, but in all instances I get only 8 bit color depth (Wonder Woman UHD disk) from projector. I use projector information option to determine color bit depth. Projector is supposed to support expanded color space (HDR10), which requires at least 10 bit color depth, but can only get 8 bit. What am I doing wrong? I have tried UB900 formats at both 24Hz and 60 Hz but nothing seems to work. I have asked Optoma these same questions. The RUIPRO cable is supposed to support the resolution requirements with ease.
The cable can definitely make the difference. I have 5 "high speed" HDMI cables ranging from very cheap to a $60 Monster cable, and only 2 of them will pass a 2160p/60hz signal with 10-bit HDR enabled. A lot of websites/people will tell you that you can't have 10-bit HDR at 4k resolution with a faster refresh rate than 30hz, but that isn't true. I played Mass Effect: Andormeda at 3840x2160 with full 10-bit HDR at 60fps/60hz from my PC to my Samsung tv. The same cable I used for that (the $60 Monster cable) allows the same signal on the UHZ65.
I didn't believe that the cable could actually make that difference (especially after reading that 3840x2160 at 60hz with full 10-bit HDR was impossible with current HDR standards), but it can. I bought the cable at Best Buy where I could return it if it didn't work, but it did.
I might have time to write up a review of the UHZ65 tonight. It will be far from a professional review, but I can definitely say I won't be returning the UHZ65 in favor of another projector at this point. I'm super happy with it in almost every respect, and I don't think the "deficiencies" a lot of people said it would probably have are really there. Black levels are much better than expected, brightness uniformity is great, and I can't see any RBE (which I am only mildly sensitive to). The asterisk here is that I'm not a pro, this is all just to my eyes (20/12 vision). If I didn't know better I probably wouldn't guess that it's "FauxK", the level of detail is incredible.
I'll post a more detailed review at some point soon.
