I don't know if this is the cause of your problem, but I have
encountered some "beat frequency" problems related to refresh rate. On a
couple of systems, I found that 72Hz refresh produced a more stable
image than did 75Hz. There is apparently an interaction between some
frequencies used inside the monitor that produce some jitter when run at
75Hz (or possibly other frequencies on different monitors). Try changing
the refresh rate to see if it improves and stabilizes your display.

This morning, all seems fine.  On very close inspection, is see the
image actually moves in an out extremely quickly.  You can't tell unless
you are on it in the corner.  I suspect it's been doing it a while and
that's why my eyes hurt!
