Overscan

Configure your display to fill your entire TV screen. With this option, your display may be larger than the displayable area on your TV screen. In other words, the edges of your display may be cut off.

Because most TVs use overscan by default, you may prefer using this option for viewing full-screen video with your TV.

Note: While this feature is enabled, other TV output controls for size and position are unavailable.
