Donux You are so grossly misinformed:
- No there is no "sweet spot resolution", I've used 27 4k scrren which cause no strain and also had experience with 27" 1080p which caused imeediate strain.
- No there is no "only two panel manufacturers" and Samsung does not produce any panels since 2018(?), however the do design their panels and outsource their manufacture to CSOT and AUO. Now there 4 major IPS panel manufacturers (BOE - by far the market leader these days, LG, Innolux, AUO) and 3 major IPS panel manufacturers (Innolux, AUO, CSOT). Neither LG nor Samsung put their panels in their monitors- LG uses exclusively BOE and Samsung does not make panels at all.
- TUV are mostly useless certificates, outside the low blue light certfication. There is a plenty TUV certified products which strain eyes. I own one, a quite expensive device.
You should probably tone down your attitude, especially with such a poor knowledge of the topic.
