Multiple Screens Registry Settings (Windows CE 5.0)
The registry stores information necessary to configure the system for applications and hardware devices. The registry also contains information that the operating system continually references during operation.
To specify the number of screens present in a multiple screen system, set the HKEY_LOCAL_MACHINE\SYSTEM\GDI\MONITORS\TOTAL MONITORS registry entry equal to the number of screens. You should only set this registry entry to a value between one and four because Windows CE supports a maximum of four screens. The default value is one. The following code example shows how to specify that the system has four screens.
[HKEY_LOCAL_MACHINE\SYSTEM\GDI\MONITORS]
"TOTAL MONITORS"=dword:4
