So for instance, my laptop is connected to a projector via VGA cable, is there a way to control when I want to display the laptop's desktop in the projector? I'm creating an interface in C# wherein if I click a specific button, the projector will display the laptop's desktop. Basically it acts like the Win + P function of windows.
Thank you for any help!

Haven't tried it myself, but these might help:

If nothing else works, there is always the simple solution: have a neutral background to your desktop (an image of the presentation name, and your contact details perhaps) and then show a form on the second monitor (maximized) when you want the projector to display. Minimize it when you don't.
