Parental, Fav's & Setup - System Setup
If you're watching a widescreen movie on a Standard 4:3 TV, you may want
to choose "Letterbox" which places bars on the top and bottom of the
screen. If your HDTV is 4:3 aspect ratio, you may want to "Crop" or cut off
the content at the left and right side of the screen while preserving the
proportion of the picture that remains. You can also "Stretch" the picture
vertically or horizontally to fill up the screen.
Bar Color: Select the Bar Color option to set the color of the bars
displayed when you view programming in Letterbox or Pillar box modes.
-TV Ratio
Set the aspect ratio that matches your TV. Options are Standard 4:3 or
Widescreen 16:9.
-TV Resolutions
Select the resolutions your TV can support so your receiver can pass the
proper signal. To find the resolutions your TV supports, check the user's
guide that came with your TV. If you select a resolution your TV doesn't
support, the receiver will reset the setting after a few seconds.
