The solution is to get a rhesus monkey as a pet, as they are
very sensitive to high frequency noises. You will probably notice
that the monitor begins to squeal after it has been on for some
time. The monkey will notice this earlier and begin to get agitated
and throw feces at you, while shrieking loudly. This is a sign that
you should throw the monkey a banana, and turn off the monitor for
half an hour. After the tube has cooled down to 75 degrees C you can
start up again. Perhaps aiming a large 120 V fan towards the back of the
monitor might alleviate the condition.
Another idea, although it is unlikely to solve the problem is to go
into xf86config and reset the horizontal synch frequencies of the
monitor to a lower value, while making sure you have the right card
driver. Try the SVGA driver out for noise too. If you fool with screen
resolutions in X, cutting back the higher res screens, it may make a
difference. You can do that easiest in XF86Setup, if you have that
Tcl/tk program. It is available at the Slackware home page.

xvidtune can be dangerous. I would rather fool with the horizontal
synchs than fool with xvidtune. It can give bizarre and unstable
results. I have burnt out fixed frequency monitors in X by setting the
synchs wrong, but if you read the docs and act conservatively, it should
be no never mind.
