POSSIBLE SOLUTION
• Verify on the User Settings menu that closed captions are
enabled on the VMS1100 set-top.
• Verify that closed captions are enabled on the TV.
Note: Closed captioning may not be available on the
current program.
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 VMS set top 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 VMS1100 set top is tuned to a
4:3 program.
• Set the TV TYPE to 4:3 Pan-Scan. This enables the VMS
set top 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).
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 VMS set top 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 your TV.
