i just got a new 4k tv (not for gaming, my parents need a upgrade from their 2004 crt lol) and i realized the motion interpolation/smoothing works rather well. i have an old hdmi so its 30fps 4k at max, but doom looks 60 fps (havent checked other games). obviously it'll never be as good as true 4k 60 but 30 to 60 is a huge performance demand, why dont computer monitors have this technology? i'd rather save tons of money on hardware for a bit of sacrifice in details. and checkerboard as well, 1440p 60 checkerboard to 4k 60 will probably only be a bit of sacrifice in detail.
