How to Connect Two Monitors in Windows 7

Method 1 of 2:

Verify that both monitors are plugged in to your Windows 7 computer. Most Windows computers support VGA or DVI-I cables, but you may need to purchase an adapter if your computer lacks the necessary built-in port.^[1]
Power on your computer.
Press the Windows logo key and the letter 'P' at the same time. A series of monitor options will display on-screen.
Select one of the following options: 'Duplicate,' 'Extend,' or 'Projector only.' 'Duplicate' will display the same screen on both monitors, 'Extend' will allow you to navigate a full screen on both monitors, and 'Projector only' will show your screen only on the second monitor.^[2]
