decision is that when you arrange your displays on the Settings tab, the location
of the monitor icons accurately predicts what happens when you move your
mouse pointer between displays. For example, assume that you have two displays
side by side. One of the displays is a 19-inch monitor and one is a 15-inch
monitor. You can arrange these displays on the Settings tab so that either the tops
or the bottoms of the displays are aligned. If the tops were aligned, whenever you
move your mouse pointer from the bottom of the bigger display toward the second
display, the pointer would get “stuck.” To get the pointer over to the smaller
display, you would have to move the pointer upward to the point where the bottom
of the smaller display was. Although it seems as if it might not be a big deal,
losing track of your mouse pointer because of this arrangement is a common
complaint among multiple-display users.

on the secondary display.
Lesson 1 Configuring and Troubleshooting the Display
Activate the device in the Display Properties dialog box.
Confirm that you chose the correct video driver.
Restart the computer to confirm that the secondary display
initialized. If not, check the status of the video adapter in
Device Manager.
Switch the order of the adapters in the slots. (The primary
adapter must qualify as a secondary adapter.)
Select the secondary display rather than the primary one in
the Display Properties dialog box.
Confirm that the secondary display adapter is supported.
Confirm that Windows XP Professional can detect the
secondary display.
Run the application on the primary display.
Run the application in full-screen mode (for Microsoft
MS-DOS-based programs) or maximized (for older
Windows-based programs).
Disable the secondary display to determine whether the
problem is specific to multiple-display support.
