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.

It depends on how "turn off" function is implemented in the monitor and in the its driver. – Effluent 15/9, 2014 at 11:20

Just turn off the monitor and check whether it is disappeared in the Device Manager. – Effluent 17/9, 2014 at 5:39

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