Configuration
Aspect Ratio (No AFD or AFD Disabled)
When the input signal has no AFD coded information on it (reported on the
Aspect Ratio web page as
Not Present)
or if the AFD processing has been dis-
abled in the AFD Control section, the aspect ratio mode selections are avail-
able as described in the section below.
Note The default Aspect Ratio web page will also include an Auto mode if the input
signal has no AFD. Auto mode is used only when AFD is present. Disabling
AFD when present will remove the Auto mode button on the web page.
• Full Width – this mode will stretch a down converted image to fit the
screen with top and bottom margins. An image set to this mode will
appear centered horizontally in a 16:9 display with black bars on the top
and bottom of the screen (letterbox) as illustrated in
Figure 10 . The
image can be aligned with the aspect ratio controls and the matte color
of the background can be changed.

centered vertically in a 16:9 display with some cropping on either side
as shown in

aspect ratio controls.
