A shout out to the seniors in the forum:
When it comes to disable dithering, are there any known or confirmed models of INTEL/AMD graphic cards? it would be great to have some kind of a list.
If there’s already threads on this matter please refer me.
I finally managed to rule out pwm, anti-glare coating, pixel inversion and blue light, and I’m down to dithering. By now the only thing that helped to some degree is this software that is designed to change the dithering configuration of intel graphics in notebooks. http://kawamoto.no-ip.org/henteko/myapp_en.html
