Smears and streaks in video image

[sync]

My video is showing small streaks and smears. Is there any way to determine if this is caused by the monitor or video card without substituting another monitor/card?

What kind of card is it? I wouldn't be suprised to see those effects if you're using a Geforce (the MX's are especially bad in the 2D image quality department).

clean your monitor?

I just realized I do have an easy way to test this. I have a networked computer hooked up to the monitor with a kvm. I tried that and have the same problem, so it's the monitor. It is quite old.
