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.
