There was an urban myth back in the late 80's and
early 90's that there
was a virus going around that could alter the scan rate of a video
adapter so that it would blow out the monitor. Never saw any such
damage to a monitor in person, so I don't know if it was just a myth or
actually existed.
Its not an urban legend. The issue was that there was a sync register
(horizontal sync, I think) for which you could poke in a zero value.
That's what I recall anyway, although I can't dredge up anything by
google at the moment.
