Problem
Possible Solution
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.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the IPC1100 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 STRETCH setting is OFF. To set 4:3 SD
programming to fill the screen, depending on the capabilities of the TV, set
4:3 STRETCH to On.
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 IPC1100 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, colors will not appear correctly on your TV.
