Appendix E: Aspect ratios explained
The appearance of a projected image on the screen depends on a combination of the following:
l
The display resolution is
WUXGA
with a 1200 x 1920 resolution, corresponding to an aspect ratio of 16:10
l
The aspect ratio of the input signal: usually
4:3
,
16:9
or
16:10
l
The value of the
Aspect Ratio
setting of the projector:
l
16:9
,
4:3
,
16:10
and
5:4
stretch the image to the selected aspect ratio.
16:9
leaves black bars at the top and bottom of the screen (letterboxing
effect);
4:3
and
5:4
leave black bars at the sides of the screen (pillarboxing).
l
TheaterScope
is a special setting used in combination with an anamorphic lens, an optional accessory. It removes letterboxing from a 2.35:1
source packed into a 16:9 frame.
l
Source
shows the image with its original aspect ratio, if this does not match the native aspect ratio of the DMD
TM
, then the image will be scaled to
either fit the full width or height of the display.
