Widescreen TVs display 4:3 programs in this format unless set to Stretch.
If the DCX3520e-M is connected to a widescreen TV, verify that the TV
TYPE is set to 16:9 in the User Settings menu.
Many HD programs are broadcast in pillar-box format with black bars to the
left and right of the picture. These programs are broadcast in 16:9 HD
formats, even though the video is not 16:9.
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. Set the
TV TYPE to 4:3 Pan-Scan. This enables the DCX3520e-M 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).
