    And then they invented the colour wheel. And the DMD with lots of tiny mirrors. And afterwards they used LEDs and laser diodes…

      RGB flashing sequentially is the wooooooorst. Most people can’t see it but holy shit i can and it’s like random colored strobes flashing everywhere. Bleh

        Yes, I could tell if dlp, whenever my eyes moved.

        They fixed the issue by increasing the color changing frequency in led beamers.:)

          I still see it in even the most modern projectors, but I’m also able to see the flicker in phones that use pwm dimming which only a very small percent of people can see, so sucks to be me. My eyes seem to work at a much higher image capture rate than most people, which has no apparent benefits, only problems

              Interestingly enough crts didn’t seem to cause a problem, my guess is because the pixel phosphors don’t actually flash off, they fade out. But that’s just a guess

                Interesting.

                It was hard for me to tolerate the 50hz flickering. Especially in peripheral vision. Same with fluorescent tubes. Good times (not).

                  Oh yeah fluorescent tubes are a awful. They’re not white, they’re sequentially yellow blue yellow blue yellow blue
