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.

•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 QIP7000 series is tuned to a 4:3 program.

•Set the TV TYPE to 4:3 Pan-Scan. This enables the QIP7000 series 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 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
	QIP7000 series cannot correct the video. You may be able to minimize the
	border using the zoom feature on the TV.
