Automatically detect whether there is a projector connected to a computer

I want to write a program to automatically detect whether there is a projector connected to a computer, and whether the projector is open? I don't know how to do this. Could you give me some suggestions on how to do it. I use the C# language.

Solution

Maybe you could check if another display is connected? Im not sure but you may be able to get details from the display and see if it is a projector.
