Xbox One owners can now make their DVDs full screen by using the Xbox One’s “Full Screen” mode. This mode is available when you select “Display” in the “Settings” menu. To use this mode, you must first enable it in your Xbox One’s “Settings” menu. Then, you must set up a movie player on your computer. The player should be able to play DVDs that have a resolution of 1080p or higher. Finally, you must add the DVD to your Xbox One’s " Movies & TV" library.
