GetMonitorDisplayAreaSize 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.
Retrieves a monitor's minimum, maximum, and current width or height.
Syntax
_BOOL GetMonitorDisplayAreaSize(
[in] HANDLE hMonitor,
[in] MC_SIZE_TYPE stSizeType,
[out] LPDWORD pdwMinimumWidthOrHeight,
[out] LPDWORD pdwCurrentWidthOrHeight,
[out] LPDWORD pdwMaximumWidthOrHeight
);
Parameters
[in] hMonitor
Handle to a physical monitor. To get the monitor handle, call GetPhysicalMonitorsFromHMONITOR or GetPhysicalMonitorsFromIDirect3DDevice9.
[in] stSizeType
A member of the MC_SIZE_TYPE enumeration, specifying whether to retrieve the width or the height.
[out] pdwMinimumWidthOrHeight
Receives the minimum width or height.
[out] pdwCurrentWidthOrHeight
Receives the current width or height.
[out] pdwMaximumWidthOrHeight
Receives the maximum width or height.
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_DISPLAY_AREA_SIZE flag.
This function takes about 40 milliseconds to return.
The width and height settings are continuous monitor settings. For more information, see Using the High-Level Monitor Configuration Functions.
