  _Out_  LPDWORD pdwCurrentDrive,
  _Out_  LPDWORD pdwMaximumDrive
);

Return value

If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. To get extended error information, call GetLastError.

Remarks

Drive settings are generally used to adjust the monitor's white point. Drive and black level are different names for the same monitor setting. If this function is supported, the GetMonitorCapabilities function returns the MC_CAPS_RED_GREEN_BLUE_DRIVE flag.

This function takes about 40 milliseconds to return.

The drive settings are continuous monitor settings. For more information, see Using the High-Level Monitor Configuration Functions.
