Problem
Possible Solution
There are black bars to the right
and left of the picture
Wide screen 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 wide screen TVs to
stretch the video to fill the screen (see your TV manual for
information about stretching 4:3 video).
•
If the DCX700 is connected to a wide screen 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.
There are black bars above and
below the picture
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 DCX700 is tuned to a 4:3
program.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the DCX700
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 your TV manual for information
about zooming 4:3 video).
There are black bars on all four
sides of the picture
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 wide
screen 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 DCX700 cannot
correct the video. You may be able to minimize the border
using the zoom feature on the TV.
Colors do not appear correctly
Be sure to match up each signal to the same YPbPr
connection on the TV, otherwise the colors will not appear
correctly on your TV.
