SYMPTOMS
After you configure Microsoft Windows Media Player to use full-screen visualizations, you may experience one or more of the following symptoms:
 * A white or black rectangle may appear on your secondary monitor.
 * A white or black rectangle may appear on the desktop of your primary monitor.



CAUSE
This behavior may occur when a program uses Microsoft DirectX Application Programming Interfaces (APIs) to switch the screen resolution to a smaller size. When this occurs, the desktop from the primary monitor may be displaced to the secondary monitor. Note that this symptom disappears when you quit or minimize the program that caused the resolution change.



WORKAROUND
To work around this behavior, use either of the following methods.

Windows Media Player 7.0, 7.1, and Windows Media Player for Windows XP

 * 1) In Windows Media Player, click Options on the Tools menu.
 * 2) Click the Visualizations tab.
 * 3) Click the visualization you are using, and then click Properties.
 * 4) Click the screen size that matches the resolution of your primary monitor.

Windows Media 9 Series Player

 * 1) In Windows Media Player, click Options on the Tools menu.
 * 2) Click the Plug-ins tab, and then click Visualization under the Category field.
 * 3) Click the visualization you are using, and then click Properties.
 * 4) Click the screen size that matches the resolution of your primary monitor.

Note You may not be able to customize some visualizations.

Method 2
In Windows Media Player, click the Maximize button.



STATUS
This behavior is by design.



MORE INFORMATION
