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
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 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

I believe the crt projector doesnt have that issue
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’m going to actually you lol

Yes, I could tell if dlp, whenever my eyes moved.
They fixed the issue by increasing the color changing frequency in led beamers.:)

Useless superpowers… :) CRTs must have been fun.

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
