SYMPTOMS
If you extend the desktop to a secondary monitor on a laptop computer that has 16 megabytes (MB) or less of video memory, you may receive the following error message if you try to use the Windows XP 3D Pipes screen saver:

Direct3D Pipes Screen Saver has encountered a problem and needs to close. We are sorry for the inconvenience.

Other Windows XP 3D screen savers may also cause this error message.



CAUSE
The 3D Pipes screen saver cannot determine that the video memory is shared between the primary and secondary video ports. Therefore, the screen saver tries to allocate more video memory than is available for each of the monitors. This causes the error message. The 3D screen saver might not generate any error message when this issue occurs.



WORKAROUND
When you are using the DualView feature (you have extended the desktop to another monitor), select any screen saver except for the 3D Pipes screen saver that is included with Windows XP.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
