After a month of Sick->Vacation->Parents->Sick I'm finally catching up on stuff. I played with my TV trying to figure out what was broken on it when it comed to my HDMI setup and finally got everything set up I as best I could.
The TV now detects every device hooked up to it, so that's good. The Wii U and Switch play fine at 1080p and 5.1 sound.
The PS5 won't play at 4K for some reason. It maxxes out at 1440p, although the TV goes up to 2160p. It also won't play HDR. The TV doesn't detect it, and if the PS5 tries, it just shows a white and pink distored screen.
Oddly, Linux works fine with it. All the way up to 2160p. And while it's notorius for having issues with HDR, it seems to be playing it fine. The downside? OMG EVERYTHING IS TINY. SO TINY. I can scale the screen, but it also scales the graphics, so you lose the benefits of 4K. Which is fine - I cna scale it for computer use (Rare) and unscale it for media use (which I do 99% of the time).
Color and sound are really nice - although the sound wasn't an issue with the new TV (I just turn the sound off on the TV and let the 5.1 do its job). I use the Transformers Movie to calibrate color, and the Wormhole Sequence of ST:TMP 4K for sound. They went nuts with the sound mix there.
