The single biggest problem laptop users have is understanding what mirroring is and how to turn it on.

Mirroring is when the image from a laptop is displayed on the laptop screen AND through a projector. If you turn on the projector first, connect it to the laptop and turn on the laptop LAST, most laptops will do this automatically.

In case it does not, laptops use a key combination to activate mirroring. It involves pressing the "Function" key (labeled" fn") and usually located in the lower left corner of the keyboard plus some other key.

Currently, there are 21 laptop manufacturers. Each manufacturer can produce multiple product lines (example: Dell makes 7 different laptop lines). Most manufacturers use the same key combination on all their product lines, but that is not always the case. Before you need it, learn this key combination.

New Dell laptops (running Windows 7) use a minidisplayport connection instead of VGA. Do not use an Apple adapter. Use a StarTech MDP2VGA available online.

Look on the keyboard for a key in the top row that is either marked with the letters "LCD/CRT" or a square monitor icon. Press and hold the "fn" key in the lower left corner of the keyboard and then that key to activate the mirroring function.
