There is no truth at all to the variable voltage rumor.... As I understand it,
a vital component of the original IBM PC monochrome monitor would overheat and
burn out if the horizontal sweep frequency was too far out of spec, which was
easily possible to program into the video controller. Other manufacturers
spent a few cents more and avoided the problem....
