Yah, probably both :-)  I read a news item a while back about a study of
the effects of monitor "whine".  Women and younger men can hear the 15.75KHz
squeal very well, and apparently it has the same effect on women as hearing
a baby's cry for help.  Thus, said this study, it might explain A) why most
women didn't like early computers and B) that the stress caused by the sound
contributed to miscarriages usually blamed on VDT "radiation".

Whether that's true or not, I don't know.  But the study's solution was
to use higher freq monitors (eg: VGA 30Khz... beyond normal hearing).

>I don't think it necessarily means the monitor will go soon.

I don't think so either.  I vaguely recall someone recommending that a bead
of putty be run down the edges to try to dampen out the vibration.  Me,
I just whack the monitor :-)
