GetCapabilitiesStringLength function (lowlevelmonitorconfigurationapi.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 the length of a monitor's capabilities string.
Syntax
_BOOL GetCapabilitiesStringLength(
[in] HANDLE hMonitor,
[out] LPDWORD pdwCapabilitiesStringLengthInCharacters

Parameters

Handle to a physical monitor. To get the monitor handle, call GetPhysicalMonitorsFromHMONITOR or GetPhysicalMonitorsFromIDirect3DDevice9.
[out] pdwCapabilitiesStringLengthInCharacters
Receives the length of the capabilities string, in characters, including the terminating null character.
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.

This function usually returns quickly, but sometimes it can take several seconds to complete.
