A 4k tv even feels like a waste to me on normal video viewing. I have no 4k bluray player and I don't collect physical movies. My internate data is capped, and watching 4k media via the internet would suck that pool dry. The only reason I have a 4k tv now is hype, and someone gifted it to me.
The main thing that matters are native resolution, the size of the display, and viewing distance. PC gamers with a monitor are in a good position to save a lot of wasted power with a smaller screen and being pretty close to it. They can then used that saved power for whatever raytracing solution is picked and used across all video cards, and other graphics goodies.
Oh and 144+ hz !!!!!!
