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

mode to fill the image in the 16x9 display as much as pos-
sible.

you to watch a 2.35:1 content (include Anamorphic DVD
