Hi Adam,

Just a guess but, do you and have you always had your tower right next to
your monitor. I've run into many a mechanical designer with the same
problem. They move the tower and problem solved. If this isn't the case
then please, ignore me.

More common than that is an electric fan or other AC powered device, motors
and transformers make monitors wiggle like crazy.
