At what level in resolution (4k, 8k, etc) is something higher resolution than average human eyes max out at and why?
In: Biology
So here’s the actual answer: under motion we can see at a general maximum of 120 “pixels” per degree of vision, at the center of our vision.
For those wondering why it’s not 60 pixels like the eye charts seem to say, that’s because it’s a line “pair” that can be distinguished, thus 2 samples and not 1.
Thus what really matters is how much of your vision is taken up be the screen. Which should be obvious, smash your face against a 4k screen and of course you’ll see the pixels.
Thus, if you have a screen that takes up 60 degrees of view, really big tbh, an 8k screen is indeed needed to “match”your eye resolution. It’s a little over but whatever. The whatever part comes from another fun fact that if you are looking at a still image your visual acuity along a given axis increases by around 70% further still, in under a second.
