I don’t think that’s true at all.

I realize the geometry predicts some optimal spot for viewing the curve but that just is a mathematical ideal not a real world necessity. If it was then everyone who has ever watched a flat screen would be like “omg I feel like I’m too close because I’m not watching from infinity.” I have a 35” monitor with 1800R and it is very pleasant in a normal desktop setting. I looked into 1000R screens since I like to sit fairly close and the curve felt so extreme that it was a major distraction no matter which distance I sat at.

I guess I’m saying that the curvature is very much a personal preference thing and if people can tolerate a flat screen they can also tolerate a curve that isn’t meeting some mathematical ideal.
