The UMPC Display Emulator is easy to use; however, it is not a hardware emulator or virtualized operating system. The UMPC Display Emulator is a developer tool intended to provide a quick and easy way to check screen layout and behavior at screen resolution of a UMPC. The UMPC Display Emulator sets your screen to the resolution of an ultra-mobile PC (800 × 480), while leaving your monitor"s physical resolution at its current setting. Essentially, the tool shows how your program, which is designed for a standard graphic user interface (GUI), appears in the typical resolution of an ultra-mobile PC.
Note: Because the ultra-mobile PC runs Microsoft Windows XP, it isn"t necessary to run a different operating system in the emulator-it"s still your desktop or laptop computer that is running; nothing is different, including the development APIs.
