Detail information about LBX mode:
1. Some Letter-Box DVDs are not enhanced for 16x9 TVs. In this
situation, the image will not look right when displayed in
16:9 mode.
In this situation, please try to using the 4:3 mode to view the
DVD.
If the content is not 4:3, there will be black bars around the
image in 16:9 display. For this type of the content, you can
use LBX mode to fill the image on the 16:9 display.
2. If you use an external anamorphic lens, this LBX mode allows
you to watch 2.35:1 content without black bars at the top and
bottom of the screen. By doing so, lamp power and resolution
are fully utilized.
