At what level in resolution (4k, 8k, etc) is something higher resolution than average human eyes max out at and why?
In: Biology
Tl;dr, with today’s tech 8K would do it.
As far as resolution goes (aside from other aspects of the visual experience) there’s two competing limits: visual acuity (the smallest detail the eye can resolve) and field of view (the breadth of view that the eye can take in. Both are measured in units of angle so trigonometry comes into the picture.
Messing around with [Carlton Bale’s home theater calculator](https://carltonbale.com/home-theater/home-theater-calculator/), using a 65″ 8K monitor from 3-1/2 feet away (oof) you would be able to see the entire screen while looking anywhere on the screen (wide enough field of view) and also be unable to discern individual pixels (high enough resolution).
