You can optimize your HD Receiver output to match the settings on your
HDTV.
- Video Tab:
The Video tab lets you set Native mode ON or OFF. Native Mode looks at the
digital aspect ratio and resolution of the program coming into the receiver and
sets your TV to the same format on-the-fly. For example, if your particular
program is being broadcast in 4:3 aspect ratio and 720p resolution, your HD
Receiver tells the TV to show it in that same format. If the next program changes
to 16:9 and 1080i, the receiver tells the TV to change to that format. You do not
need to choose Native mode because your HD Receiver will adjust and change
the picture to fit your TV as described in the following paragraphs. In fact, Native
Mode slows down the response of your system to channel changes because the
receiver and TV must communicate at every channel change before the video
comes up on the screen. Therefore, the default position is OFF, but your can
override it if you wish.
Choose the color of the bars you prefer when viewing an image in letterbox (or
pillar) mode.
Choose the screen format you prefer for the instances when the broadcast
does not exactly fit your TV screen and the HD Receiver will automatically
size it. For example, when viewing very wide format movies you can choose
to have letterbox bars on the top and bottom of the screen. This preserves
the proportions of the images on the screen. Or you can choose to stretch the
images vertically to fill up the screen. If your HDTV is 4:3 aspect ratio, you may
want to choose "crop" to cut off the content at the left and right side of the
screen while preserving the proportion of the images that remain.
