Line moving up monitor (1 Viewer)

I have two monitors running with separate video cards in my computer. There is a line constantly moving up the screen. When it gets to the top, it reappears at the bottom again. Is there some basic problem that causes this?

The electromagnetic field from one monitor is causing interference on the other. You can try different combinations of refresh rates, otherwise the only way to solve it is to put some distance between them.

Always with the electromagnetic interference....

Would it help to put something on the side like aluminum foilto block the signal?

Sell the CRT's and get a pair of LCD's.
