 Detail informations 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.
    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 fi  ll 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 fi  lm 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 
vertical resolution is fully utilized for maximum viewing ef-
fects.
    Other than these two occasions, one should stay with 16:9 
and 4:3 modes for most viewing experiences.
