Computer Stops Responding When Enabling Multiple Display Support

When you click "Use this device as part of the desktop" to enable a secondary monitor for use with the Multiple Display Support feature, your secondary monitor may not display anything, and your computer may stop responding (hang).

This issue can occur if a i=B000-B7FF entry exists in the Emm386 line in the Config.sys file.

To resolve this issue, use System Configuration Editor (Sysedit.exe) to remove the entry in the Config.sys file. To do so, follow these steps:

1. Click Start, click Run, type Sysedit in the Open box, and then click OK.
2. On the Windows menu, click Config.sys.
3. Locate the line that loads Emm386 and delete the "include" statement. The line may read as follows:

         C:\Windows\emm386.exe noems i=B000-B7FF 
    
   						

   The corrected line should read as follows:

         C:\Windows\emm386.exe noems
    
   						

4. On the File menu, click Exit.
5. Click Yes when you are prompted to save the Config.sys file.
6. Restart the computer.
