They do that.  The 6153 monitors do, too.

The tubes do seem to be somewhat prone to burning-in
when they're left on continuously, but my guess is
that this is a different problem.  IBM always just
replaced monitors when we complained that they were
dim.  Somebody who really understands TV sets might
be able to suggest a fix.

Not that I know of, but I don't know much.  If your
monitor becomes unusable, you can run an ordinary
EGA card and monochrome monitor (but no X-windows).
