Select Cinema to view 2.35
source material in its native
aspect ratio.
With a 16:9 screen and a
standard Q-750d Ultra (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 DHD
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.
A 16:9 image is scaled
NON-linearly (more on the sides
than in the center) to fit a 2.35:1
screen.
Select Native to display the
source signal in its native
resolution, centered in the
display area with no re-sizing or
overscan.
This means, for example, that
720p HDTV programs will
display with unused pixels on all
sides: 320 on the left and right
sides and 180 above and below.
With SDTV and EDTV sources,
the DHD Controller scales the
image horizontally to achieve a
16:9 aspect ratio.
