Set your preference for the following screen options: Native,
Screen Format and Bar Color.
Native: You can turn Native mode ON or OFF. When Native
Mode is ON, your TV auto-changes to match the resolution of the
program coming into the receiver. For example, if Native mode is
ON and a program is being broadcast in 480p, your HD Receiver
tells the TV to show it in that same format. If the next program
changes to 1080i, the receiver tells the TV to change to that
format. Native mode slows down the system's response time
to channel changes since the receiver and TV must adjust the
picture resolution at every channel change. Because of this, the
default setting is OFF. When Native Mode is OFF, your receiver
will display the program at the highest resolution set on the "TV
Resolutions" screen.
Screen Format: When a program is broadcast in a format that
does not fit your TV screen, your receiver adjusts the picture size.
Options include Original Format, Pillar Box (Widescreen 16:9
HDTVs only), Letterbox (Standard 4:3 TVs 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.
