Possible Solution
Widescreen TVs display 4:3 programs in this format
unless set to Stretch. Turn on the 4:3 OVERRIDE feature
in the User Settings menu. This enables most
widescreen TVs to stretch the video to fill the screen
(see your TV manual for information about stretching 4:3
video).
If the cable terminal 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.
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 cable terminal is tuned to a
4:3 program.
Set the TV TYPE to 4:3 Pan-Scan. This enables the
cable terminal 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
widescreens TVs offer a zoom feature that may be able
to remove the black bars (see your TV manual for
information about zooming 4:3 video).
