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

  I’m going to actually you lol
  
  The reason it works better with CRT is because of the phosphors. They continue to glow, long after the signal has passed over. Check out a CRT slow motion.
  
  Everything to do with display technology involves tricking the eye and relying on persistence of vision which is innate.

  I was referring to the spinning color wheel that op was taking about, but yeah the simultaneous three color projector likely doesn't have that problem
