Laptop External Screen Problem Answered

My Dell Latitude D820 screen broke today. I have no idea how, because it was in a car, and worked fine when I put it in, and was cracked and full of lines when I took it out. I never realised how flimsy the screen was ,or how prone to breaking. I will get the screen replaced next week, but my problem right now is that I have to do some urgent work on it, and as I cannot see anything on the laptop screen, I plugged in a desktop screen in the back, but it does not work. Nothing happens. The power light on the desktop monitor just keeps flashing, and I have tried everything from re-booting to inserting the interface when the laptop is on - but nothing works! I understood that if you wanted a bigger screen, all you had to do was plug in a bigger screen and forget about the laptop screen - but this does not seem to be the case! Help!

. I think mikesty is on the right track. My Father has a laptop (not sure of make/model) that he has to go through a similar routine with. . The blinking power light on the monitor would lead me to believe that it is not getting a signal. If mikesty's instructions don't work, double-check cable/connectors/etc.

Plug everything in and boot the laptop. Press the FN (purple usually, the function key) and then look for a monitor symbol on one of the F (function) keys on the top row, usually like F3 or something, and whatever key it is, press that. Wait and it should come up on the screen after about 10-15 seconds tops. If not, press the two keys simultaneously again. This should switch it from the screen mode to the desktop monitor mode.
