Well, I had the same problem with my Sony monitor.  As it cropped up
some time after I got my computer, I thought it was my computer's fault,
and I took it into to get it repaired.  Of course, there was nothing wrong
with it.  Turns out that the Vertical Sync (or was it the Horizontal?, can't
remember, and I always get the two confused...) was misadjusted, and 
twiddling with that knob fixed the problem.

The above could explain it -- or your monitor may be syncing bad with the
original signal.

Of course, I've got a 500, so I'm not able to do this, sigh...
The whole idea was to wait for the A3000 to come out -- I figure it might
be available by the time I get out of school (2 more years).

Ideas?  What ideas?  If I had any idea I was going
to have an idea I wouldn't have posted this nonsense.
