How can I determine if my displays are in "Clone Mode" without using either COPP (Computer Output Protection Protocol) or OPM (Output Protection Protocol) on Windows?
Vista solution:
hMonitor = MonitorFromWindow (HWND_DESKTOP, MONITOR_DEFAULTTOPRIMARY); bSuccess = GetNumberOfPhysicalMonitorsFromHMONITOR (hMonitor, &dwMonitorCount);
