mike Same experience. Now that I 3 months ago started to have problems with ALL displays, like TV as well, patching my right (non-dominant) eye helps if not removes the issue totally.
What is interesting is that I have tried to use my wife's OLED phone with 240Hz PWM eye-patched, and it does not either cause any discomfort.
So it is BVD or some spasm related, not a windows or display driver version problem for me. Hoping to get the problem that started 3 months ago to the level it was when I was able to tolerate some non-PWM screens.
