To use more than one display
Under Windows XP
-
Make sure you have securely connected the additional displays you want to use to the appropriate connections on your NVIDIA-based graphics card installed on your computer.
-
Verify that your displays are plugged in and turned on.
-
From the NVIDIA Control Panel navigation tree pane, under Display, click Set up multiple displays to open the page.
-
In step 1, select a multi-display mode such as Clone, Horizontal Span, Vertical Span, or Dualview.
-
NOTE: Horizontal and Vertical Span modes are available only under Windows XP.

In step 2, click the display pair list and select the pair of displays in the order that you want to use them. For example, for display pair A + B, you can choose the “A + B” option or the “B + A” option.
The desktop appears on all your displays.
In Clone mode, your desktop is duplicated on each display; in Span mode, the desktop is stretched across the displays; and in Dualview mode, you have extra desktop space on the additional display, which you can configure independently, move your desktop items to, distribute applications to, etc.
Note: If any one of your displays isn’t showing an image, make sure to repeat steps 1. and 2. If that doesn’t work, restart your computer and repeat the above steps.
