The maximum size at which 1080p (2K) works is 23". The maximum size at which 1440p works is 30". The maximum size at which 2160p (4K) works is 40". If you’re using a larger size than the ones given above for a given resolution, you will have less than 96dpi, leading to fonts that break or become too thin, and icons that will be less recognizable. ________________________ P.S.: The same can be said for colors. While any CRT in the 90s but even early LCDs like the Fujitsu SIEMENS P17-2 from 2004 (now 30€ on eBay) gets 100% sRGB, full 8-bit colors at exactly 96dpi, many gaming monitors don’t even manage this today. There are still gaming monitors, 1080p at 30" or even 32" using 6-bit panels with FRC that barely hit 70% sRGB on sale today.
