It’s not necessarily picky - it’s sometimes about physically different perception.

When DLP projectors first came out, I couldn’t watch them. I would see colors breaking in fast motion scenes and whenever I would move my head even slightly (and … we all move our head slightly often when watching a movie).

When I told other people, some of them nodded in understanding, but the vast majority thought I was making things up - for them, it was a rock solid picture.

One of my friends replied: “I can see about 300hz. Not all the time - only when I have secadic movements; but that means many fluorescents, DLPs and other light sources drive me crazy. I guess you’re also a member of crazy club”

Some people can hear 26khz. Some people can see DLPs. Some people can see the alternating pattern….
