System Setup
Screen Format: When a program is broadcast in a format that does
not exactly fit your TV screen, your receiver will automatically size the
picture. Screen Format options include Original Format, Pillar Box
(Widescreen 16:9 HDTVs only), Letterbox (Standard 4:3 HDTVs only),
Stretch and Crop.
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.
