Dual Monitors in Windows 7 - Quick Fix

I disconnected one of my monitors, don't ask why, when I reconnected it the display was not active. Could I remember how to get both monitors working? Anyway a quick google reminded me that all you have to do is press the Win and P keys to show the appropriate dialogue box. Select the "Extended" option and Bingo, two monitors working again.
