Output Format Option
The aspect ratio is designed to help you select the way your television picture displays when
you are watching a program in a different format. For example, the way a standard television
displays a widescreen program or the way a widescreen program displays a standard program.
You can set the aspect ratio from the Settings Menu (in the Output Formats Preference) or
using the Output Format Options Ribbon.
The following examples will help you decide which option to select.
• When selecting an aspect ratio for a standard 480P Std or 480i television, you have the
following options: Zoom and Letterbox.
• When selecting an Output Format option for a 1080i, 720p or 480p (widescreen)
television, you have the following options: Sidebar 4:3 Image, Stretch 4:3 Image, Preserve
4:3 Image- 480p, or Keep 4:3 Image - 480p, Keep 4:3 Image - 480i. The Preserve options
cause the set-top box to output a 480 format picture to the television and let the television
convert it as it is designed. Three possible options are shown; there may be others.
