It's not clear what you mean by "control video output" here. If your goal is to manage the display modes and then display full-screen output, you should read Quartz Display Services Programming Guide, which will walk you through most of that.

A simpler solution in many cases, though, is to just create a borderless window using the frame of the the desired screen. You can get information about the available screens in Cocoa using NSScreen. Then it's just standard window drawing.
