GUID_DEVINTERFACE_OPM

The GUID_DEVINTERFACE_OPM device interface class is defined for display adapter drivers that operate in the context of the Windows Vista Display Driver Model and support output protection management (OPM) for monitor child devices.

Remarks

Drivers register instances of this device interface class to notify the operating system and applications of the presence of OPM device interfaces.

If a display miniport driver supports a direct-call OPM interface for this device setup class, a kernel-mode component can retrieve the direct-call interface by calling the miniport driver's DxgkDdiQueryInterface function and supplying GUID_DEVINTERFACE_OPM to specify the interface type.

For information about OPM, see Supporting Output Protection Manager.
