Solution
Once you have both monitors connected, right click anywhere on the desktop (under windows 7) and select resolution.
-Select the resolution you would like each monitor to use (works best with identical resolutions)
-Select which monitor will be your main display (this is the one that will have the windows taskbar and start button)
-you can drag and drop the monitors in the window at the top to change where the monitors are situated on the windows desktop

press and hold the windows key, then press "p". select extend from the menu.

enjoy!

p.s.
Dual = two
Duel = a fight
Connect both monitors to two display output ports on your graphics card. Then go to your graphics settings and make sure the resolutions are set right and the screens are orientated correctly. Windows also has tools to adjust the display onto the monitors. It is a very simple process.
