Yea I'm in the same boat, I had a 32" 1080p screen from 2012 that has worked great, however in my new apartment it's too far away and hard to see from a distance.
Anyways I bought the TCL P605 from Best Buy and while the colors, HDR, and resolution on the panel are quite nice, there are clouds in the corners, around the bottom, and some backlight bleed on the bottom left and right. I may have to play the panel lottery for this one or return it.
There's quite a bit of tearing from my PC to the TCL, even though I'm mirroring my desktop from 60hz to 60hz, and I couldn't get HDR to work from Windows 10 Creators Update on the panel either, it appears as HDR but has the gray tonal look from it being HDR on standard playback. I tried fiddling with Nvidia drivers since there's a few way to control colors from there, but that didn't seem to help either. In the end I had to get some code to force the monitor into HDR mode, but I believe that PC HDR is more of a Nvidia/MS problem than a TCL one.
