I know this doesn't help much, but it's the video card, the monitor or the cable.
Try swapping DVI-D cables first as it's the cheapest.

I have a brand new 2013 mac pro ... same problem. Anyone have a resolution?

I also have this issue. Black areas of the screen show static across them. Any solutions? Apple?

Have you tried swapping video cables?
As I mentioned it's one of three things; especially with the 2013 Mac Pro I'm more inclined to believe it to be the cable or monitor than the video card.
