Best Gaming TV

Wasn't really sure where to put this and technically am looking for multiple opinions/debates and preferences so I can look into them myself.

I currently have side by side Samsung TVs that are going on 10 years old. They do the job but they are nothing special at all. There is a 60 (UN60F7100AF) I use for gaming next to a 40 (UN40H6350AF) I have older consoles/PC/Cable box plugged into. I typically dual screen watching a streaming service next to the game.

The 40 has gone from a couple burnt? blotches (much larger than pixels and bright white) around the edges to about 12 of them scattered about the screen all evenly distanced from others would be (based on the ones near each other and diagonal from others).

Question 1: What TV do you use for your gaming? Brand/Model/etc.

Question 2: Should I replace both? Keeping current sizes and setup or should I switch the cable/streaming stuff to the still just fine 60 and purchase something in the 40-46 range to replace the one with issues and use it for future gaming? I know the world of gaming TV size is a very large debate so what size have you preferred to use?

1) I use the LG OLED C1 65" as my primary gaming TV for PC, Switch, Xbox SX and PS5 ; the old consoles I have are connected to an old LCD TV I bought back in 2019, so NES won't work on it. But the old consoles are in my room, the current gen is in my living room.

2) I'd say it depends on the level of quality you want to have for each use. If you want UHD for both Netflix (for example) and games, you'll have to go for two UHD TVs at some point. Your setup sounds impressive though, I'd usually game on my LG TV while listening to something on my laptop right next to me.

So... not really sure that helped.
