Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • displayPrimaryRed is the reference monitor’s red primary in chromaticity coordinates

  • displayPrimaryGreen is the reference monitor’s green primary in chromaticity coordinates

  • displayPrimaryBlue is the reference monitor’s blue primary in chromaticity coordinates

  • whitePoint is the reference monitor’s white-point in chromaticity coordinates

  • maxLuminance is the maximum luminance of the reference monitor in nits

  • minLuminance is the minimum luminance of the reference monitor in nits

  • maxContentLightLevel is content’s maximum luminance in nits

  • maxFrameAverageLightLevel is the maximum frame average light level in nits
