Select Cinema to view 
2.35 source material in its 
native aspect ratio.
With a 16:9 screen and a 
non-CineWide projector 
(no anamorphic lens), the 
upper and lower portions 
of the screen are 
masked, but the 
geometry of the active 
image area is 
unchanged.
With a 2.35:1 screen and 
a CineWide-equipped 
projector, the video 
processor scales the 
2.35:1 image so that the 
active image area fills the 
16:9 chip surface, 
eliminating the black 
bars. The secondary, 
anamorphic lens then 
restores the proper 
geometry to the 2.35:1 
image.

A 16:9 image is scaled 
NON-linearly (more on 
the sides than in the 
center) to fit a 2.35:1 
screen.
 
Virtual Cinema is 
available only on 
CineWide-equipped 
projectors.
