First, thank you very much , guys.
A lot of great advice here, it really helped me make my computer usable, and most of the headaches, or maybe all are gone.
My current setup:
OS:Windows 10 1903,
Graphic Card: Intel HD5500 Graphics,
Graphics Driver:Intel HD drivers, Version: 18.104.22.16874 , 2016, Intel says they're especially againt flicker.
Display:Benq GW2270, supposed to be flicker free. At 100% brightness. Browser brighteness is controlled via "Dark REader" chrome extension.
I'm currently testing my display using my phone camera and the notepad app fully opened. At a certain distance, i do see flicker lines.
Same results when graphics driver is disabled.
Is it possible, under windows, to fully solve that ? And for that , would i need to install windows 10 1507?
