We have to stop talking about resolution only in terms of being able to see pixels. Not being able to see pixels is not the final limit to human vision. If it was 4k monitors and TVs would have never become a thing. There are other aspects like seeing aliasing or the blurriness introduced by antialiasing that is a particular challenge to small text and very well perceptible well beyond the point where you can spot individual pixels. It's incidentally also something Apple pointed out as the strength of the Vision Pro. So I wonder, how does the perceived sharpness compare to other Pro branded products by Apple?
