SetMonitorRedGreenOrBlueDrive function (highlevelmonitorconfigurationapi.h)

Warning

The physical monitor configuration functions work using the VESA Monitor Control Command Set (MCCS) standard over an I2C interface. Many monitors don't fully implement that standard; so your use of these commands might result in undefined monitor behavior. We don't recommend using these functions for arbitrary monitors without physically validating that they work as intended.

Sets a monitor's red, green, or blue drive value.

Syntax

_BOOL SetMonitorRedGreenOrBlueDrive(
  [in] HANDLE        hMonitor,
  [in] MC_DRIVE_TYPE dtDriveType,
  [in] DWORD         dwNewDrive
);

Parameters

[in] hMonitor

Handle to a physical monitor. To get the monitor handle, call GetPhysicalMonitorsFromHMONITOR or GetPhysicalMonitorsFromIDirect3DDevice9.

[in] dtDriveType

A member of the MC_DRIVE_TYPE enumeration, specifying whether to set the red, green, or blue drive value.

[in] dwNewDrive

Red, green, or blue drive value. To get the monitor's minimum and maximum drive values, call GetMonitorRedGreenOrBlueDrive.

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 50 milliseconds to return.

Changing the drive settings can change the color temperature. To get the new color temperature, call GetMonitorColorTemperature.

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