clear line on monitor

[topdogo]

all of a sudden i have a clear line on my monitor about 1" in length and 1/8" in depth, would this be the monitor or the video card.

It sounds like the monitor but it would be best to test the monitor and video card one at a time hooked up to a different computer.
