 Detail informations 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 en-
hanced for 16x9 Display in a wide 2.35:1 image. 
    In this case, there are no black bars, the full lamp power and

fects.
    Other than these two occasions, one should stay with 16:9 
and 4:3 modes for most viewing experiences.
