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. – Kirill V. Lyadvinsky Sep 15 '14 at 11:20
Just turn off the monitor and check whether it is disappeared in the Device Manager. – Kirill V. Lyadvinsky Sep 17 '14 at 05:39

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