SYMPTOMS
When you configure your Windows XP-based computer to use multiple displays, and one or more of the displays uses a screen resolution that is greater than 1920 x 1440, some of the three-dimensional screen savers do not appear correctly. You may experience one or more of the following symptoms:
 * In the 3D FlowerBox screen saver, the shape does not move across the whole span of the larger display.
 * In the 3D Flying Objects screen saver, nothing appears on either display.
 * In the 3D Text screen saver, nothing appears on either display.

Note The 3D Pipes screen saver appears correctly on both displays.



CAUSE
This problem occurs because these screen savers gather the size of each display and use the sizes to calculate the coordinates where they can draw the shapes. When one or more of the displays is greater than 1920 x 1440, these calculations can cause the shapes to draw at coordinates that do not appear on the displays. When this behavior occurs, the display is blank.

This problem does not occur on a computer that uses a single display, even at a very high resolution.



STATUS
Microsoft is researching this problem and will post more information in this article when the information becomes available.
