Question

a try diffent monitor
b video card
c nothing above

Answer 1

I would try both a different monitor and a different video card.


Troubleshooting computer problems like this is all about isolating the issue.

If it does the same thing with a new monitor, then it is probably the card.

If neither of those things help, then it is probably the cable.
If it does it with the new card, it is probably the monitor.

Answer 2

Try different monitor on the computer you are using, try this possible defective monitor on a different computer, check the video cable from the monitor to the computer, then that should help narrow down the cause.
