Remarks

Drivers register instances of this device interface class to notify the operating system and applications of the presence of brightness control interfaces for monitor child devices.

If the display miniport driver supports a direct-call brightness control 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_BRIGHTNESS to specify the interface type.

For information about brightness devices, see Supporting Brightness Controls on Integrated Display Panels and Brightness Control Interface.
