I need some kind of event from Windows whenever there is a monitor that's getting plugged into system. Is there any API in Windows to do that. BTW, it is an C++ application
Use RegisterDeviceNotification to register for getting WM_DEVICECHANGE notification.

You can do it via WMI, AFAIK. I've never tried it though so I can't give much help
