I mean, it could… but if you run the math on a 4k vs an 8k monitor, you’ll find that for most common monitor and tv sizes, and the distance you’re sitting from them…
It basically doesn’t actually make any literally perceptible difference.
Human eyes have … the equivalent of a maximum resolution, a maximum angular resolution.
You’d have to have literally superhuman vision to be able to notice a difference in almost all space scenarios that don’t involve you owning a penthouse or mansion, it really only makes sense if you literally have a TV the size of an entire wall of a studio apartment, or use it for like a Tokyo / Times Square style giant building wall advertisement, or completely replace projection theatres with gigantic active screens.
This doesn’t have 8k on it, but basically, buying an 8k monitor that you use at a desk is literally completely pointless unless your face is less than a foot away from it, and it only makes sense for like a TV in a living room if said TV is … like … 15+ feet wide, 7+ feet tall.
The graph suggests that you should be looking at a 65-inch screen from a distance of 120 cm for resolutions above 4k to be worth it. I interpret that as the distance at which the screen-door effect becomes visible, so this seems awfully close actually.
A 65-inch screen has a width of 144 cm, which gives you a 100 degree angle of vision from the left edge to the right edge of the screen. Divide the approximate horizontal resolution of 4000 pixels by 100 and you get an angular pixel density of 40 PPD (Pixels Per Degree).
However for the pixel gaps to become too small to be seen or in other words for the screen-door effect to disappear, you need an angular pixel density of 60 PPD. That means you can sit at a more reasonable distance of 220 cm in front of a 65-inch screen for resolutions above 4k to be worth it.
This is still too close for comfort though, given that the resulting horizontal angle of vision is 66 degrees. The THX cinema standard recommends a horizontal viewing angle of 40 degrees.
So multiply 40 degrees by 60 pixels per degree to get a horizontal resolution of 2400 pixels. That means the perfect resolution for TVs is actually QHD.

That graph is fascinating, thank you!
I don’t think it’s correct though.

There’s obviously truth to there being diminishing returns, but this chart is garbage.
