Hello people.  I've got a SuperMac 19" Triniton monitor on my Mac II with a
Spectrum-8 video card.  There seems to be a horizontal flickering;  not a
flickering in the sense that the image is flashing, but rather that the screen
lines are shaking horizontally.  Thus if I draw a horizontal line, it appears
basically stable (unless you look at the tips), but if I draw a vertical
line, the whole thing appears to shake. (I hope I haven't just confused
people!)

Anyway, the thing is really driving me crazy.  Looking at it for long
periods of time drives my eyes crazy, reading text on it gives me a headache,
and large graphics with open fields of white have those horrible "waves" that
run through them.

For a monitor this expensive, this should not be happening.  Any suggestions
short of lugging this 90 pound monster into the shop?

Thanks,
