There could be another answer to this. The good news is that it isn't your
monitor. It could be that you just don't have enough shielding inside of
your computer case. That flimsy tin metal around CDROM enclosures work
pretty well. I run my Mac G-3 right next to the rack and my receive coax
runs right along side of the computer. I get no noise at all. The one thing
I've noticed on the G-3 is that the case has good, solid shielding on the
sides, front, and back. My wife's iMac is about 3 feet away and it doesn't
produce any noise either. That has a little motherboard in a tray
construction that is heavily shielded.

I remember having a drive that would produce momentary hash when it would
spin up to speed. That was a few computers back and I don't remember the
details except that it was one drive in particular.

Maybe you can turn your case or tower some and see if the hash changes or
goes away. That sometimes works well if you get out of the radiation path.
