Monitor isn't working with my new Dell.?

I use a ViewSonic VS15032 with my laptop (using a blue VGA 15-pin connector) and it works fine. But I just got a new Dell desktop and when I plug it in, the monitor just says "No Signal".

Any idea what's wrong? The computer sounds like it turns on and the keyboard/mouse light up.

On some monitors there is a button to adjust the computer to the screen resolution try messing around with the buttons to see if that solves your problem happened with a projector in class one time.

May sure you have plugged the cable into the correct VGA slot, if you have a discrete graphics card you must use that and not the onboard VGA
