What size of TV are you looking at?
I have PS4 Pro and Xbox One X. Paired with an older Vizio 70" P series (NON-HDR BOO!) Picture is great even non-HDR. Xbox one X does a better job then the PS4 Pro with 4k, even I hate to admit that as I am a PS kinda guy. I also PC game on the TV once in awhile. Although most of the PC Gaming is on the 1440res monitor with 144hz and G-Sync.
Here is an article a couple months old with some listed TV's for gaming.

Good luck!
