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.
