In response to my post re. flickering screens, Kelly Burhenne quoted
my earlier post:

And asked <<Is this why computer screens always "flicker" on TV?>>
As far as I know, the problem is that the computer monitor and the TV
screen flicker at different frequencies, which exaggerates the problem
of flicker, so you end up with a strobe-like effect. (Sort of the same
reason why the spokes on wheels appear to run backward once they
rotate at a certain speed.)
