Secondary Display Only Shows Desktop Background in Windows XP
When attempting to use a secondary display (monitor or television), only the desktop wallpaper is shown.
This could be due to either of two reasons.
- Extended Desktop could be enabled. Extended Desktop will allow more than one monitor to spread the desktop over a larger area. The secondary monitor will then display the desktop background only by default. To use the secondary display, move the mouse pointer off the edge of the screen (right side by default) and the pointer will appear on the second display.
- If extended desktop is not enabled, the second display will show the view of the first display. This is known as desktop cloning. If the display is larger than the screen's maximum resolution, the display will scroll to view the items off screen. To scroll the secondary screen, move the mouse pointer to the desired area on the primary screen. If the location is off screen on the secondary display, it will scroll to the area on the primary display.
Set up multiple monitors
One monitor serves as the primary monitor. Most programs will display windows on the primary monitor when you first open them. You can also set different screen resolutions on each monitor. To set up multiple monitors:
- Click Start > Control Panel.
- Click Appearance and Themes, and then click Display.
- On the Settings tab, click Identify. A large number will mark each of your monitors. This shows which monitor corresponds with each icon.
- Click the monitor icons and drag them to positions that represent how you want to move items from one monitor to another, and then click OK or Apply to view changes.
The icon positions determine how you move items from one monitor to another. For example, if you are using two monitors and you want to move items from one monitor to the other by dragging left and right, place the icons side by side. To move items between monitors by dragging up and down, place the icons one above the other. The icon positions do not have to correspond to the physical positions of the monitors.
Set primary monitor
To determine which monitor will be treated as the primary, follow the steps below.
- On the Settings tab of the Display Properties dialog box, click the icon that represents the monitor you want to set as the primary monitor.
- Click the Use this device as the primary monitor check box. This check box is unavailable for the current primary monitor.
Extend desktop across multiple monitors
To use your monitors as one large desktop space, follow the steps below.
- On the Settings tab of the Display Properties box, click Identify to display a large number on each of your monitors.
- Click the monitor icons and drag them to positions that represent how you want to move items from one monitor to another, and then click OK or Apply.
- Drag an item on your desktop across your screen until it appears on the alternate monitor. Or, you can resize a window to stretch it across more than one monitor.
