simplex hi , i don’t know why I feel eyestrain and headaches when using back windows 10 but the windows is newly installed. I even tried to install windows 7 again , I still feel eyestrain and headaches. So the problem is newly installed windows , no matter windows 7 or windows 10.
I am thinking some default settings that can’t be changed when windows are newly installed. What display setting can be changed before the Windows’s installation? Many thanks ! I am desperately looking for solution.
