Letterbox mode scales (zooms
in on) a 4:3 image linearly (by the
same amount on all sides) to fill
a 16:9 display.
Letterbox is best suited for
viewing LaserDisc movies or
"full-screen" DVDs on a 16:9
screen.
VirtualWide scales a 4:3 image
NON-linearly (more on the sides
than in the center) to fit a 16:9
screen.
On a 2.35:1 screen, the image is
centered between black bars on
either side.
Select Cinema to view 2.35
source material in its native
aspect ratio.
With a 16:9 screen and a
standard X-400d/X-450d
(without an 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 an
anamorphic lens, the Dimension
Digital Controller 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.
