That is the question we all face. We definitely don't all have the same issues. Some are affected by PWM while others aren't. I believe my issue may be temporal dithering. Some have issues that are tech dependent like you mentioned. My apologies to those I am leaving out with other panel/tech issues.
The good thing is the discussions is getting larger and larger. Some review sites are already testing for PWM flicker. Hopefully temporal dithering will gain ground and be discussed when displays are reviewed. Hopefully the issues many face here will start to trend and be considered when displays are released.
This forum is gains momentum pretty well. There's a lot of knowledge spread here and a lot that I am learning. I believe this can only benefit us. Will we see the fruits of our labor as soon as we hope? Not sure, but I'm glad the discussion is involving more and more people.
