> 4k is 2160 vertical, so that's about the limit of human vision.

This is false. Misalignment of borders can be detected with a precision up to 10 times better than visual acuity [0], therefore your numbers should be multiplied by 10, meaning 40K is the optimal screen resolution, or 80K for people with particularly good vision.

It assumes no anti-aliasing.

Anti-aliasing is the display counterpart of hyperperacuity.

Here is a paper: https://www.researchgate.net/publication/320353446_Effects_o...

Its conclusion is that with anti-aliasing, you only need half the resolution to reach the detection threshold for misalignment of borders compared to other visual acuity tests.

I always noticed I could do this, but wasn't sure what it was called. Thank you!
