Hello Kevin!
I know how to initialize an external display and how to insert a view, but if I want to init a secondWindow with a ViewController?

that blue view is a ViewController called containerViewController and I need to add the viewController when an hdmi adapter is on. But I can't loose the view in the iPad, like happens now.
I have the observer, but If I do
[self.secondWindow setRootViewController:self.containerViewController];
I don't see anything...
Thank you!
