If I federally register a copyright for a computer program, will the registration/copyright cover the outputted screen displays?

According to the United States Copyright Office, a computer program and the screen displays it generates are generally considered the same work, because most screen displays are created by the program code. If the same party owns the copyright in the program code and the screen displays, the program and any related screen displays can be registered with the same application. But if different parties own the copyright in the program code and the screen displays, separate applications are required.
