Until December I could use my private PC (Win 10 Pro, 21H1) with a VGA->DVI cable without eye strain. Since December this no longer works (although nothing was changed at that time, but I had a lot of stress).
My work laptop (win 10 education, 21H1) is still somewhat comfortable (at least significantly better than the private pc). I have yet to find out if this is due to the Intel GPU/drivers, the special enterprise image, or Win 10 Education. When I boot Linux (on a USB stick) on the work laptop, I have eye strain again.
