Detail information about LBX mode :1)   Some Letter-Box DVD contents are not enhanced for 16x9 TV, 
then image will not look right in 16:9 display. One can use 4:3 
mode to view the correct info. But if the content itself is not 4:3, 
it will have black bars around the image in a 16:9 display. For 
this kind of content, you can use LBX mode to fill the image in 
the 16x9 display as much as possible.
2)    If you use an external 16x9 lens, this LBX mode also allows 
you to watch a 2.35:1 content (include Anamorphic DVD and 
HDTV film source) that support anamorphic wide is enhanced 
for 16x9 Display in a wide 2.35:1 image. In this case, there are 
no black bars, the full lamp power and vertical resolution is 
fully utilized for maximum viewing effects. Other than these 
two occasions, one should stay with 16:9 and 4:3 modes for 
most viewing experiences.
