Members
Type
A value of type D3DKMT_BRIGHTNESS_INFO_TYPE that indicates the type of brightness information to retrieve or set.
ChildUid
An integer that uniquely identifies the child device.
PossibleLevels
A D3DKMT_BRIGHTNESS_POSSIBLE_LEVELS structure that contains information about all possible brightness levels that the integrated display panel supports.
Brightness
The current brightness level.
BrightnessCaps
A DXGK_BRIGHTNESS_CAPS structure that represents the brightness control capabilities of the integrated display panel.
BrightnessState
A DXGK_BRIGHTNESS_STATE structure that represents the smooth brightness control capabilities of the integrated display panel.
OptimizationLevel
A DXGK_BACKLIGHT_OPTIMIZATION_LEVEL structure that represents the optimization level of brightness control.
ReductionInfo
A value of type DXGK_BACKLIGHT_INFO that provides the current absolute level of backlight reduction.
VerboseLogging
A boolean value that indicates whether Event Tracing for Windows (ETW) logging of brightness information should be verbose.
NitRanges
List of supported nit ranges.
GetBrightnessMillinits
Queries the driver for the current brightness level, in millinits.
SetBrightnessMillinits
Directs the driver to linearly ramp the brightness from its current brightness level to a target brightness level over a specified length of time.
