So here it goes,
Before my problems started I had dell e5570 that sadly had to be returned for other reasons. It had AUO panel - fhd anti-glare, i5-6440hq, amd r7 m370.
this is my black list:
laptop #2 – dell e5570 (fhd anti glare LG panel, i5-6300u, intel hd 520, win 7 + win 10)
laptop #3 – dell latutide 3550 (fhd anti glare LG panel, i5-5200u, intel 5500, win 7 + win 10)
pc monitor #4 – Toshiba c55-b (hd glare, connected through hdmi to my current benq vz2470h monitor, Pentium n3530, win 7 professional). here's a screenshot of the gpu specs from hwinfo: (right click on the image --open image in new tab)
i also tried to connect the benq to android tv box (gpu: mali 450). i downloaded "pimp my rom" app and disabled dithering but it wasn't any better.
can i count that the dithering is gone with this benq (true 8bit)? Any ideas what else I should check?
