I recently built a PC with an RTX 4090, and i7 13700KF.
I used a 49” monitor for years with Mac, I could be in front of it all day, no eye pain at all.
I use the exact same settings, same cable with the PC, and both Windows and Ubuntu are causing heavy eye pain after 10 minutes. It’s like pixels are running around, and I have to focus like an eagle to read text. Very uncomfortable. I also use night light to reduce blue light. I tried all settings, different cables, nothing worked.
I remember many years ago I had a laptop which was fine, I reinstalled Windows then it got the same eye pain issue. Then in service they set it up correctly, and the eye pain went away.
This is a £3k PC which I cannot use at the moment because the eye pain is not only while using the PC, I can feel the dizzyness the next day too.
Now the question is if I switch to a CPU with iGPU, is it possible that the issue will go away? I’m asking because it would be a quite expensive trial as CPU returns are usually not welcome, and no one would buy a 13700KF.
Thanks in advance
