Hi all. I've been a member of AVSForum for something like two decades now, though I've been absent a while so it's nice to be back.
Anyway just got the TV on a whim and am impressed. I'm replacing a lower-end Samsung 4K 55" that I was using mostly for PC gaming, with the 49" 900E. I mounted the tv on the wall and pushed a pretty small desk up against the wall so there is maybe 3' distance from screen to eyeball.
I like the immersive effect.
Anyway I had no idea that TV HDR was even a thing until getting the set home. Fallout 4 in 4K HDR is mind blowing... it felt like Neo eating the red pill or however it went when it flipped from non-HDR to HDR. I was surprised though that it seemed to only want to do 4K HDR at 30 Hz. So i did at least a minimal amount of research and I guess that limitation was due to pixel clock limitations due to the extra bits on every pixel that take up signal bandwidth.
I got HDMI 2 cables thinking that would make a difference but it didn't (at least not immediately). Some more digging however turned up the Nvidia control panel custom resolutions, and after frustration with that a bit more digging turned up Custom Resolution Utility (CRU).
Long story short (er, at least) i did manage to flip, check, and mangle things on the HDMI and HDMI 2 pages to the point where it's now doing 10bpc YCbCr 4K 60Hz, which was pretty much my goal. I'm curious if I can get it to do 444 but a lot of the impetus to fiddle with it is gone given that I've achieved the objective.
Oh, this is paired to an EVGA 1070 GTX.
Anyway here's the screen shot (no "Apply" button in the bottom right means this is current settings...)
(sorry i'm in the noob ghetto I can't post files or links)
I'm sure there's some way to dig out the CRU settings if there's interest, or worst case write them down or more screen shots or something.
