When you try to extend the desktop to a secondary display while Windows Media Player is playing a video on the primary display, you may experience one or more of the following symptoms:
- Although the sound continues to play, the video may be missing.
- The video may stop, and when you try to start it again, you may receive an error message, or it may play sound without a video.
These symptoms may also occur when one of the following scenarios is true:
- You try to turn off the extended desktop on the secondary monitor while video is playing.
- You are using a third-party video playback program other than Windows Media Player.
This problem is caused by a limitation of Microsoft DirectDraw.
To work around this issue, use one of the following methods:
- After you turn off or turn on the extended desktop to the secondary display, stop your video playback program and then start it again.
- Turn off or turn on the extended desktop before you start the video playback.
- Try to make the video play in full-screen mode.
- Move or rotate the monitor before you start the video playback.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
