Like the title says, I am wondering where I should start with this idea. I want to be able to display the output from a secondary monitor in a window on the primary monitor, sort of like a Picture-In-Picture configuration.
The reason I want to do this is because I have a set up whereby I have two monitors, they are set up to extend the desktop but I cannot physically see what is being displayed on the second monitor while looking at the primary one.
I have been looking on MSDN about the screen class which may be a start. https://msdn.microsoft.com/en-us/library/system.windows.forms.screen.aspx
Can anyone tell me where I should be starting with this or whether it is possible?
