Video
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 High-
Definition 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 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 TVs only), Stretch and Crop.
