Using Both a Monitor and Your Computer Display
You can attach an external monitor or projector to your computer and use it
as an extension of your display (known as
dual independent display or extended
desktop mode). This mode allows you to use both screens independently and
drag objects from one screen to the other, effectively doubling the amount of
viewable work space.
To use extended desktop mode, perform the steps in the following section
that corresponds to the operating system your computer is using.
Microsoft Windows XP
1 Connect the external monitor, TV, or projector to the computer.
2 Click Start→ Settings→ Control Panel.
3 Under Pick a category, click Appearance and Themes.
4 Under Pick a task..., click the area you want to change, or under or pick a
Control Panel icon, click Display.
5 In the Display Properties window, click the Settings tab.
NOTE:
If you choose a resolution or color palette that is higher than the
display supports, the settings adjust automatically to the closest supported
values. For more information, see your operating system documentation.
6 Click the monitor 2 icon, click the Extend my Windows desktop... check
box, and then click Apply.

without restarting and click OK.
