Andreiid No, I did not tested the Asus Pro Art.
Now, I am using:
Dell S2421HN - IPS Panel, very good, sharp text, nice colors (this one, because the one I've returned was not great )
Dell SE2422H - VA Panel, not as sharp as S2421HN, but good enough for home use.
In last 2 years I tested also some smartphones:
Galaxy S22 - can't use for more then 10-15 minutes (very strong eye strain and headache. If I used 2-3 hours daily, I wake up with eye strain and headache second day)
Galaxy Z Flip 4 - same, can't use for more then 15 minutes.
Galaxy S22 Ultra - was ok for me. Returned because hardware problems ( proximity sensor fault)
Galaxy S23 - same as S22 (can't use for more then 10-15 minutes (very strong eye strain and headache. If I used 2-3 hours daily, I wake up with eye strain and headache second day)
Iphone 11 - eye strain, not as much as Galaxy from what I remember.\
Iphone 12 - very eye friendly, I can use it all day long. This one I kept.
