DXGK_BRIGHTNESS_INTERFACE_2 structure (dispmprt.h)

The DXGK_BRIGHTNESS_INTERFACE_2 structure contins pointers to functions in the Panel Brightness Control Interface Version 2. Used by Windows Display Driver Model (WDDM) 1.2 and later display miniport drivers that support adaptive and smooth brightness control.

Syntax

Members

[in] Size

The size, in bytes, of this structure.

[in] Version

The version number of the brightness interface. Version number constants are defined in Dispmprt.h (for example, DXGK_BRIGHTNESS_INTERFACE_VERSION_2).

[in] Context

A pointer to a private context block.

[out] InterfaceReference

A pointer to an interface reference function that is implemented by the display miniport driver.

[out] InterfaceDereference

A pointer to an interface dereference function that is implemented by the display miniport driver.

[out] GetPossibleBrightness

A pointer to the display miniport driver's DxgkDdiGetPossibleBrightness function.

[out] SetBrightness

A pointer to the display miniport driver's DxgkDdiSetBrightness function.

[out] GetBrightness

A pointer to the display miniport driver's DxgkDdiGetBrightness function.

[out] GetBrightnessCaps

A pointer to the display miniport driver's DxgkDdiGetBrightnessCaps function. This function is available starting with Windows 8.

[out] SetBrightnessState

A pointer to the display miniport driver's DxgkDdiSetBrightnessState function. This function is available starting with Windows 8.

[out] SetBacklightOptimization

A pointer to the display miniport driver's DxgkDdiSetBacklightOptimization function. This function is available starting with Windows 8.

[out] GetBacklightReduction

A pointer to the display miniport driver's DxgkDdiGetBacklightReduction function. This function is available starting with Windows 8.

Remarks

This structure provides additional members, beyond those in the DXGK_BRIGHTNESS_INTERFACE interface, that point to driver-implemented functions that control, measure, and optimize display panel brightness and allow smooth brightness control.
