DegaussMonitor Function

Degausses a monitor. Degaussing improves a monitor's image quality and color fidelity by demagnetizing the monitor.

Syntax

  BOOL DegaussMonitor(
  HANDLE
    hMonitor

  );

Parameters

hMonitor

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

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

If this function is supported, the GetMonitorCapabilities function returns the MC_CAPS_DEGAUSS flag. Degaussing is supported only by cathode ray tube (CRT) monitors.

This function takes about 50 milliseconds to return.

This function should not be called frequently, because calling it frequently will not noticeably improve the monitor's image quality or color fidelity.

Requirements

Client: Requires Windows Vista.

Header: Include HighLevelMonitorConfigurationAPI.h.

Library: Use dxva2.lib.
