Yes but who will stand around and look at it happen?  That is why 
there are not many virus but there was a torjens back in the days 
before EGA that would burn out the mono monitors.  But it was a 
easy fix, you replace the horz. out put transistor.  And by the 
way decreasing the scaning freq. will cause a monitor to burn out 
faster as the horz. transistors duty cycle genrates more heat at 
the lower freq, (uses more power).
