If you are using an analog connection to the monitor, I suggest upgrading to DVI. Also, make sure the cable is firmly connected at both ends, has no sharp bends, or other signs of physical damage, and does not run past any potentially high sources of noise, such as electrical wall transformers, speakers, power strips, breaker panels, etc.

I suspect you're already using DVI, as the usual sign of signal loss is the screen blanking out or trying to re-sync to the source signal. If you were using analog, it likely wouldn't blank out but instead show picture degradation. Easiest way to test is with another cable. You can also try moving the cable around a bit and see if this causes the screen to blank out and re-sync again.

It could be a bad cable or a defective monitor. I don't think it's your GPU.
