I only vaguely described the symptoms above. The picture began to
flicker for a few days, on and off, during which time a sharp whack to
the rear of the monitor case seemed to return it to the correct path.
After a few days, however, the vertical just threw in the towell,
leaving me with an entire screen full of picture in a bright
horizontal line in the middle of the screen.

Though I didn't change the video cable, as it was firmly attached to
the monitor, I did change video cards with no change in results.
Also, while the monitor was in the warranty return purgatory, I made
do with an older monitor I dusted off from the garage, with no
performance problem.
Given these new facts, does this still sound like a vertical sync
problem? I really don't know, so I'm grateful for the collective
expertise of the PLUG list.
Thanks for your help, Keith.
