DXGK_BRIGHTNESS_INTERFACE_3 structure (dispmprt.h)

Contains pointers to functions in the Panel Brightness Control Interface Version 3. Used by Windows Display Driver Model (WDDM) 2.4 and later display miniport drivers that supports multiple displays that can be set to calibrated nit-based brightness levels.
