The HKEY_LOCAL_MACHINE\Drivers\Display\Active\key contains subkeys for display drivers currently in use on a Windows CE–based platform. Each subkey shares the name of the display driver that it serves. The following table describes the values contained in each subkey.
|Value name||Value type||Description|
|BufferMode||DWORD||Controls the correlation between the display adapter's frame buffer and the frame buffer for any built-in displays on the Windows CE–based platform. BufferModemust be set to one of the following values: 0 means no common frame buffer, 1 means that the top half of the display adapter's buffer is mirrored on the built-in display, 2 means that a scaled-down version of the display adapter's frame buffer is mirrored on the built-in display, and 3 means that the built-in display is turned off while this driver is active.|
|Dll||REG_SZ||Name of the .dll file that contains the display driver.|
|TapMode||DWORD||Controls how tap or click events are managed. TapModemust be set to one of the following values: 0 =tapping not supported, 1=tap coordinates are unmodified, 2=tap coordinates are scaled to match the display driver's coordinate space, or 3=tap coordinates are undefined, but tap events are still delivered to applications, optionally with coordinates 0,0.|
The following example shows the contents under the Displaykey for a sample display driver.
HKEY_LOCAL_MACHINE [Drivers] [Display] [Active] [GenericVGA] SZ: Dll = GENVGA.DLL DWORD: BufferMode = 0 DWORD: TapMode = 0
