SMS: Determining If a Client Will Use Video Acceleration

ID: Q198749

The information in this article applies to:

SUMMARY

When a client machine is being remote controlled, the client controls the process that decides whether the video will be accelerated. This can be checked by looking in the client's registry in the following location:

HKEY_LOCAL_MACHINE\Hardware\DeviceMap\Video.

Compare the values of the \Device\Video0 (and the driver seen as ...Services\<video driver>) to the corresponding value in the following location:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\<video driver>\Device0.
The InstalledDisplayDrivers key must be either a key by itself; for example, SVGA, or, if the InstalledDisplayDrivers key contains multiple entries, each entry must be separated by a single space; for example, VGA SVGA VGA256 SVGA256.

This can also be checked by double-clicking the Remote Control icon on the client's desktop and looking at the Status window. If acceleration is enabled, the information appears in the appropriate status line.


MORE INFORMATION

Video acceleration is Windows NT-specific. Windows 95, Windows 98, and other 16-bit clients use the Remote Control agents (WUSER32 and WUSER) to intercept calls from the GDI to the display driver, do not require video acceleration.
