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

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
