martin The interesting thing is that my family owns a sailboat and I've NEVER gotten motion or "sea sick" when in rough weather, even before and after this "problem" with lights and screens.

    I think I've ruled out dithering (ditherig doesn't help) and PWM (can use older OLED phones) as causes, I'm wondering if there's just simply different kinds of LED backlighting and the ones used in newer devices cause me problems.

      JTL Would you think that 120 Hz phone could eliminate the problem? I am also affected in unknown ways as I cannot find anything that works for me besides CCFL external monitor and lumia 930 (stangest thing ever, as any other old phone does not work for my eyes). I also had problems with CRT monitors on 60-70 HZ, but on 120 HZ it was all fine.

          randomboolean Depends if the speed or "smoothness" of the motion is the issue. LCD's are a sample and hold technology so excluding things like dithering it SHOULD be static image when things aren't moving.

          Unfortunately things like dithering break that assumption.

              JTL An 8-bit panel and no forced dithering at the driver layer should eliminate dithering right?

                  ryans It should. It's harder to do then it sounds.

                  I have a BenQ GW2760HS on my desk and 4 GPU's I can readily test with under Windows/Linux

                  • Intel HD Graphics 4600
                  • ASUS AMD R9 270X
                  • EVGA Nvidia GTX 560
                  • EVGA GTX 1070

                  With the 1070 even the BIOS setup screen looks flickery. I tried RMA'ing the card despite my persistence it wouldn't solve things. I got a refurbished model with the same VBIOS and everything. Go figure.

                    ryans Yes, but this doesn't explain why I had a photosensitive epilepsy type reaction to some screens, among other issues.

                    What I'm trying to say is that it would be nice if the issue we were all having was that simple, but it's not.

                        JTL Did you ever get all medical checkups done, mri etc? On the intel forum someone recently found out that they did have finds on MRI

                            martin I have found one person in Prague who had similar issue, but said that in 14 days it subsided and now hes fine. Hes gotten used to it. I never heard about that before.

                              martin Yes.

                              I even have had an MRI from before I had these issues (January 2011)

                              Other MRI's taken in
                              - December 2014
                              - Sometime in 2016? (My memory is slightly foggy because I was still getting headaches all the time)

                              Doctor said "everything looked normal" and even compared the older and newer MRI's

                                  JTL why did you get the mei before you had these issues? Was there some injury?

                                      Ive read migraines and head injuries are a common connection. Could you again share more details about the cannabis treatment? Exact name, dosage, progress...? Im gonna try to get it here in Prague or metnion it. Ive been to head cavity specialist, they found a polyp but said its normal size and non cancerous, normal thing many people have. Said there is no chance to be connected with the migraines. Gave me nose spray to try just to see if it helps. Eventually Ill have to try alternative methods, cannabis etc.
