- You are using Windows 7 with a Windows Aero theme.
- You attach two or more monitors to the computer in an extended desktop configuration.
- The resulting size of the extended desktop is more than 8192 pixels wide or 8192 pixels high.
In this scenario, the desktop wallpaper may disappear, and the contents of windows may not be displayed properly. Additionally, using Event Viewer, you may see the following error in the Application log:
Log Name: Application
Source: Desktop Window Manager
Event ID: 9020
Description: The Desktop Window Manager has encountered a fatal error (0x88980406)
Alternately, use the Personalization control panel to change to a non-Aero theme, such as Windows 7 Basic.
