high latency on TVs make it bad for games etc. as anyhting thats sensitive on IO timings can feel a bit off. even 5ms compared to 1 or 2ms response times is noticable by a lot in hand-eye coordination across io -> monitor.

It sort of depends on what you perceive as 'high'. Many TVs have a special low-latency "game" display mode. My LG OLED does, and it's a 2021 model. But OLED in general (in a PC monitor as well) is going to have higher latency than IPS for example, regardless of input delay.

OLED suffers from burn-in, so you'll start seeing your IDE or desktop after a while, all the time.

I have a couple of budget vertical Samsung TVs in my monitor stacks.

The quality isn't good enough for photo work, but they're more than fine for text.

I have a MiSTer Laggy thing to measure TV latency. In my bedroom Vizio LCD thing, in Game Mode, is between 18-24ms, a bit more than a frame of latency (assuming 60fps).

I don’t play a lot of fast paced games and I am not good enough at any of them to where a frame of latency would drastically affect my performance in any game, and I don’t think two frames of latency is really noticeable when typing in Vim or something.

I hope you mean lower? An OLED pixel updates roughly instantly while liquid crystals take time to shift, with IPS in particular trading away speed for quality.

In the context of this thread that's a non-issue. Good TVs have been in the ~5ms@120Hz/<10ms@60Hz world for some time now. If you're in the market for a 4K-or-higher display, you won't find much better, even among specialized monitors (as those usually won't be able to drive higher Hz with lower lag with full 4k+ resolution anyway).
