I had the same problem with my Iiyama monitor.  I never understood the
issue.  Somehow X must have introduced subtle frequency variations
that appeared as different settings to the monitor.  I think it
somehow occurs when you're on a setting that's borderline acceptable
to the monitor.  I had to make extreme adjustments to my unstable
setting to make the display ok.

I was able to fix it by finding a list of generic VESA modelines that
tend to work well on all/most monitors.  I can provide more details
when I'm at my home Linux machine.  For starters here's a list I stole
from a email provided by Google search on "vesa modelines".  As the
email's author said, "USE THEM AT YOUR OWN RISK".

HTH,
