[comp.sys.mac] SuperMac screen flickering

gmw1@CUNIXD.CC.COLUMBIA.EDU (Gabe M Wiener) (02/20/89)

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,

Gabe,

If you haven't tried moving the video card, re-attaching the video cable, or
trying a new video cable and/or card, I'd recommend that you get in contact 
with a SuperMac Authorized Dealer.
