I was able to preview the UHD50 today against my Optoma HD29Darbee 1080p projector and have some interesting results.
-First, it's a bright projector, and it goes into bright mode with Dynamic Black on. It's almost as bright as my HD29 that is supposed to be 3,200 lumens versus the UHD50 at 2,400 lumens. That is good news.
-It can be made to look like my HD29 in contrast, but then the blacks are crushed slightly hiding detail.
-It does enhance 1080p cable to some extent, but you need to up the sharpness to get a crisp look. That said the XPR does make the image softer--not less detail--just smoother looking.
-You CANNOT disable the 4k XPR function for 1080p; at least I could not find that function like you can on the Benq HT2550, so the XPR is always on.
-It is as quiet as my HD29. Yes there is a slight hum, but along with the fan, I found it very low, and a non-event.
-It is definitely a short throw. I have a 160" screen with a useable gain of about 2.0 and the lens of the UHD50 is 14 feet from the screen. The lens from my HD29 is 18 feet away. I always have it as close as the zoom will allow. So that should great news for you short-throw fans.
-I hooked up my Samsung 4K bluray player, and "tried" to watch some 4K youtube videos. I used a 25 foot hdmi cable that I used to hook the player up to an Epson 5040 and Optoma 65 that I previewed last summer. Well, this bugger, has a handshake issue with 4K. I looked at the manual and they suggest
suggests using the HDMI cable under 5 meters.
/25Hz/24Hz suggests using the HDMI cable under 15 meters."

so the cable could be too long. I gave up on youtube, it would go in and out of sync. I put a 4K disc in the player --Passengers-- and it played on and off and on and off and on and off----ugh. So I need to get another cable. As it was playing, though, I at least got a good glimpse of 4K movie watching. The detail was excellent, but the starfields at the beginning were washed out slightly ruining the effect. It was in HDR mode as well. Oh, and the 24hz was amazingly good. The judder was well within my "ugh zone", so that was surprising. I then switched back to my HD29 and looked at the movie in 3D at 1080p, and I could not see much difference in detail, and the black star field was nicer. The only difference I saw, was in the 4K version the spaceship had more finite detail while in the starfield, while the HD29 had the detail hidden in the contrast...hmmm. Over all, I liked the 3D version better because of the 3D depth and the detail, except for the space view of the spaceship, was just as good.
-And finally, the border--oh yeah, I had forgotten to look for it until I was about to shut the UHD50 down. My screen has a 3" black border around it, and beyond that is a darkbrown wall. I could hardly see it. I had to really look for it. It was a "meh" moment. It definitely was not something distracting. I could see if you had a much smaller screen with a light wall behind it, it might be an issue, but dark wall--nope.
I couldn't get any pictures because of the unstable 4K sync. I'm going to get a better cable this weekend and try to get a better sync next week and take some pics. So far, I'm not sure the 4K is worth it, since most of my movie watching is 3D. For cable tv, my HD29 does a great job as well.
More to come...
