This may occur on a 16:9 TV if the active video for an SD broadcast is in
letterbox format. To confirm, wait for a commercial or look for a graphic,
such as a network logo. If the commercial fills the screen from top to
bottom, or the graphic appears below the active video, the program is
being letterboxed by the broadcaster. Minimize this by activating the zoom
feature on the TV.
A broadcast may include black bars on either side of a widescreen
broadcast. This is called a hybrid aspect ratio and results in a black border
around the video on a 4:3 TV. Because this is part of the broadcast, the
DCX3510-M cannot correct the video. You may be able to minimize the
border using the zoom feature on the TV.
