Interesting post from Deja Vu @ AV Forums on UHD/HDR:
"O.K. here's my take on the 940D (and UHD/HDR) -- I've had it for a couple of days.
I own a number of projectors and use three screens -- 85", 92" and 120". I presently own the following projectors -- JVC X7000 (RS500), X5000 (RS400), Epson LS10000, Epson 6010, Epson 6020, Sharp 30000, Mits. 7900 and 8000. I use them all at different times -- I can tell you the positives and negatives of each. I also use a Teranex processor to convert 2D to 3D (I like 3D!).
The 940D in my opinion is an exceptionally good LCD TV. It is so good with BD that it makes UHD rather pointless in my opinion and not worth the extra cost of the UHD discs. The black levels and shadow detail are also very, very good. It's not OLED black but very satisfying nonetheless. There is some haloing on occasion but from what I've seen it's slight when it does occur and unobtrusive. Sometimes the back light does contaminate the black bars slightly but again its slight -- I think it's important to keep the backlight at no higher than medium. I'm watching in a completely light controlled room and this TV does a great job -- I suspect I'll have it for a coupled of years so for me it's a keeper. I sit relatively close (9 to 10 feet back) and the size (75") is just big enough to be immersive. OLED is better (IMO for black levels) but this isn't far behind and the extra 10" is worth quite a bit in my opinion. If I were comparing the 940D to projectors I would say it's the JVC X7000 of TVs -- both transmissive displays that do a great job.
The panel uniformity of my set is certainly not perfect but with content it's not an issue. I don't have any visible banding. The four corners of the screen are slightly darker but again not an issue with content.
I have three UHD/HDR movies -- Chappie, Deadpool and the Reverent. IMO UHD has been completely overhyped and HDR is a step backwards. The extra resolution is hardly noticeable on a 75" set -- I compared the UHD versions with the BD versions of these three films. Furthermore, I believe HDR is just a gimmick and a step backwards -- for years we attempted to get black levels just right so we wouldn't crush it and lose shadow detail. Along comes HDR and in one swoop kiss your shadow detail goodbye all in the name of dynamic range -- low APL scenes just disappear into darkness. On top of that I found myself squinting in the bright scenes -- for me it's uncomfortable and I'm out -- I'm not wasting anymore time or money on UHD/HDR discs! The UHD/HDR discs I own look "overcooked". In addition, UHD discs are not free of artifacts. Regarding UHD/HDR -- I came, I saw, I left. I personally like the BD versions of these films much better, especially on this TV. (The UHD version without HDR was the best and maybe worth an additional dollar or two -- the actual difference is $10 to $20 more) I suspect that the public will give this (UHD/HDR) stuff a big thumbs down and if it does manufactures can get back to improving things that really count like the contrast of their displays.
Just my take -- you'll spend your money as you see fit and I'll do likewise. I just cast my vote with my wallet and I won't be spending anymore time or money on UHD/HDR -- much to do about nothing. Now I understand why the Best Buys where I am don't bother demonstrating UHD BDs and especially HDR."
