The computer I'm using is older (3+ years) and has frustrated me a few times, most notably in the past 2 months.

That said, this is a new problem. My second (DVI) monitor is detected by Windows but doesn't display anything. In both the display settings and the NVIDIA control panel, I can see a second (Impression) monitor, but it's blank and I can't get it to show anything. In fact, the monitor doesn't seem to recognize that it's connected, because the orange "power but no input" light is on rather than the green "power and input" light.

This is a Windows 7 64-bit installation on a Dell Dimension E520.

Any help you can give me is much appreciated - I want my productivity back!

Thanks in advance,

Make sure it is enabled and there is a signal being sent to it.

When using multiple monitors you have a choice of clone, extend or move the signal from one to the other.
