Chris -> 3. Can you isolate by trying to replicate the problem on another
computer?
Paul -> Not feasible. Besides, the only change to that machine is the
monitor.
All cabling the same, everything.
Perhaps that is the clue. If the previous monitor failed due to a line
spike, it's possible the cable has some damage as well. Ditto for the video
card. Highly suggest you test vs. another computer and/or monitor.

No. Can be any place. In fact, they may be happening more than we realize,
but they're only visible against certain solid color backgrounds.

All applications.

Not feasible. Besides, the only change to that machine is the monitor.
All cabling the same, everything.

Only one input on this one.
