Fitting the image to the screen
Fitting the image to the DMD
Without anamorphic lens
The projector can be configured by your installer to display a number of standard
image formats using the full height of the DMD. This means that the projected
screen height can be constant for all image formats, which is preferable for theatres
that employ only side-masking.
The exception to this is the 2.35:1 format, which can use the full width, but not the
full height of the DMD. Therefore any other image formats would have to be zoomed
down to maintain the same height.
With anamorphic lens
The projector can be configured by your installer to correctly display images that
have been compressed horizontally (or stretched vertically) by an anamorphic lens
when filmed. When the anamorphic lens is deployed, the image will be restored to
its correct aspect ratio.
In this configuration, the 2.35:1 format can use the full height of the DMD, and no
zooming will be necessary between this and other image formats.
Notes
For more information on how to
connect the projector, see
Connecting the projector,
later in this section, and
Connections, in 6. Appendix
The resolution of the DMD fitted
to the projector is 2048 x 1080
pixels.
For more information on how
the use of the anamorphic lens
will affect your choice of
projection lens, see Choosing
the lens combination, later in
this section.

Fitting the projected image to the screen
It is important that your screen is of sufficient height and width to display images at
all the aspect ratios you are planning to use.
Use the conversion chart, or the sample calculations below to check that you are
able to display the full image on your screen. If you have insufficient height or width,
you will have to reduce the overall image size in order to display the full image on
your screen.

Diagonal screen sizes
Screen sizes are sometimes specified by their diagonal size in inches (D). When
dealing with large screens and projection distances at different aspect ratios, it is
more convenient to measure screen width (W) and height (H).
The example calculations below show how to convert diagonal sizes in inches into
width and height in inches or metres, at various aspect ratios.
2.35:1 aspect ratio
W = D x 0.92  in = D x .023  mH = D x 0.39  in = D x .01  m
2048x1080, native resolution
W = D x 0.88  in = D x .022  mH = D x 0.47  in = D x .012  m
1.85:1 aspect ratio
W = D x 0.88 in = D x .022  mH = D x 0.48  in = D x .012  m
16:9 aspect ratio
W = D x 0.87  in = D x .022  mH = D x 0.49  in = D x .0125  m
1.66:1 aspect ratio
W = D x 0.86  in = D x .022  mH = D x 0.52  in = D x .013  m
4:3 aspect ratio
W = D x 0.8  in = D x .02  mH = D x 0.6  in = D x .015  m
5:4 aspect ratio
W = D x 0.78  in = D x .02  mH = D x 0.625  in = D x .016  m
Notes
D = diagonal (in)
W = width
H = height
