> You need over 95 ppd to exhaust normal visual acuity
32" 4K at 36" is 91 ppd. Which I guess is good enough, seeing as I'm well the far side of 25 year old.
> Why are you assuming 36"? Nobody I know uses 32" monitors at 36" away.
36" is the point where I can see all 4 corners of the monitor at the same time (and significantly too close to focus on one corner and have the other 3 corners in view at the same time).
40 degrees of FoV is massive for a single monitor! I'm sitting here wondering how much you have to turn your head to use this size monitor up close
I actually have two more monitors, one on each side of my main one, in portrait mode :) And yes, I turn my head when I want to see them.
I'm glad the low resolution monitors work for you. I just don't want people to proclaim that everything about displays is solved - it's not. There are meaningful, physiologically relevant improvements to be made. It's been over a decade since 4k60 became the standard. A lot of younger people would really benefit from mass produced 6k120 monitors.

You move your eyes, not your head. Plus or minus 20 degrees is a trivial amount of eye movement.
Most people are fine with this. Your requirement to comfortably see everything with minimal eye/head movement is atypical.
Even if you do have to move your head, that’s not a bad thing. A little head movement during long computing sessions is helpful.

Maybe this varies a lot between humans, because I'm trying the experiment, and any closer than 24 inches requires physically moving my head to comfortably read text in the corner of the 32" display.
Even at 36" it's fatiguing to focus on a corner of the display solely through eye-movement for more than a few seconds.

I don't think it's by any means an uncommon requirement. Movie-watchers want to be able to see the whole screen at once (with the exception of some intentionally-over-the-top IMAX theatres), gamers want to be able to see their radar/heath/ammo/etc in the corners of the screen. I'd like to be able to notice notifications arriving in the corner of the screen.
