Laptops typically have special shortcut keys to help you when you plug up projectors, but did you know that Windows 7 has a shortcut key as well? Press Windows Key + P to bring up your display and projector options!

Since I have multiple monitors on my desktop, the extend option is correct for me. Knowing this shortcut can save you time if you’re about to give a presentation and you’re having difficulty with the projector. It’s also useful when recording demos on your desktop and you want to quickly turn off your secondary displays!
