Not necessarily, different resolutions use different sync frequencies,
maybe the synchronization part has gone bad actually and it fail with
certyain frequencies... so your picture gets compressed vertically into
a strip, correct? When it happens do you hear chirping noises from the
monitor or such? I guess the ultimate test would be to test it with a
different Mac.
