Keep in mind the difference in phosphor persistence. TV CRTs are
designed with enough persistence to make 60 Hz flicker invisible.
Computer CRTs have no such limitation.

Computer CRT's also have phosphor persistence, this is also defined by the
physical size and depth of each layer of phosphor as in a TV CRT, the
difference is that the phosphor pixels are smaller, so can convert less
electron beam energy to light, and for a shorter period of time.

Hey Robin! *You* tell us why computer screens flicker on television.
Then explain why many of them have horizontal bars running vertically
through the pictures. Then explain why the bars are of different sizes
and timing from appearance from top to bottom of the screen. Then
explain why some don't.
