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.
