When you take your Tablet PC out of the docking station, and then put it back in again, the display properties may change unexpectedly. For example, while an external monitor is connected to the docking station, and you are using Clone mode so that both the external monitor and the Tablet PC LCD display the same picture, you take the Tablet PC out of the docking station and put it back in. Although the display was configured to use Clone mode before you undocked the Tablet PC, the desktop display is now stretched over both screens. Therefore, you are using DualView mode and can move items between the Tablet PC LCD screen and the external monitor.

On a portable computer that is running Microsoft Windows XP, you may be unable to switch between displays. For example, assume that the computer uses the Fn+F8 keyboard shortcut to switch between the computer's built-in display and an external monitor. When you press Fn+F8, the operation to switch between displays may not occur as expected.
Note Fn is the Function key, and it typically appears near the CTRL key on a portable-computer keyboard.
This problem may occur only occasionally. This problem is timing-specific, and it occurs only when you try to switch displays very soon after you connect an external display. For example, if you connect an external display, and then you wait for a full minute before you try to switch displays, this problem does not occur.

This article explains how to identify the type of graphics card you have installed by using Windows debug commands.
There are occasions where Windows cannot correctly identify your graphics card and your installation will complete with a default VGA adapter offering fewer colours and a lower resolution than the card can support due to the correct driver not being loaded.

This step-by-step article describes how to configure and use multiple monitors in Windows XP.
Windows XP makes it possible for you to increase your productivity by using multiple monitors to expand the size of your desktop. With the use of up to ten individual monitors connected to a single computer, you can create a desktop that is large enough to hold numerous programs or windows. You can easily work on more than one task at a time by moving items from one monitor to another or by stretching them across numerous monitors. You can edit images or text on one monitor while you view Web activity on another monitor. Or you could open multiple pages of a single, long document, and then drag them across several monitors to easily view the layout of text and graphics. You could also stretch a Microsoft Excel spreadsheet across two monitors so you can view numerous columns without scrolling.
