Possible Solution
All 4:3 HDTVs display HD programs in letterbox format (black bars above and
below the picture) because of the shape of the display screen.
•
Turn on the 4:3 OVERRIDE feature in the User Settings menu. This
enables most standard-screen TVs to display a full screen picture when
the DCX3200 is tuned to a 4:3 program.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the DCX3200 to remove
the black bars above and below the picture when possible.
Some SD programs are broadcast in the letterbox format with black bars above
and below the picture. Some widescreen TVs offer a zoom feature that may be
able to remove the black bars (see the TV manual for information about
zooming 4:3 video).
This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To set 4:3 SD
programming to fill the screen, depending on the capabilities of the TV, set
4:3 OVERRIDE to 480i or 480p.
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. You can minimize this by activating the zoom feature on the
TV.
A broadcaster may include black bars on either side of a widescreen broadcast.
This is called a "hybrid" aspect ratio and results in a black border surrounding
the video on a 4:3 TV. Because this is part of the broadcast, the DCX3200
cannot correct the video. You may be able to minimize the border using the
zoom feature on the TV.
Be sure to match up each signal to the same YPbPr connection on the TV.
Otherwise, colors will not appear correctly on the TV.
