Multiple Screens OS Design Development (Windows CE 5.0)

Article
09/14/2012

The Multiple Screens Catalog item for Microsoft® Windows® CE allows multiple screens to be connected to a device. You can use these multiple screens as one large combined screen to create more screen space for applications. This extra space is useful whenever you need to maximize your on-screen workspace and is especially useful in publishing, Web development, or video editing.

When you connect multiple screens to a device, objects can travel seamlessly between screens. In other words, you can drag a window or shortcut from one screen to another and you can increase the size of a window so that the window covers more than one screen.

The following table shows the Sysgen variables that enable the Multiple Screens Catalog item.

Sysgen variable	Description
SYSGEN_MULTIMON	When this variable is set to 1, the Multiple Screens Catalog item is included in the OS design. When this variable is not set, the Multiple Screens Catalog item is excluded from the OS design.
