Aspect ratio example: TheaterScope
The TheaterScope setting is used in combination with an anamorphic lens to restore 2.35:\
1 images packed into a 16:9 frame. Such images 
are projected with black lines at the top and bottom of the 16:9 screen \
to make up for the difference in aspect ratios.
Without an anamorphic lens and without the TheaterScope setting applied, a 16:9 source containing a 2.35:1 image lo\
oks like this:
If we change the setting to...

Fitting the image to the DMD™
If the source image supplied to the projector is smaller than the DMD™ resolution, the image will not fill the DMD™. The following examples 
show how a number of common formats may be displayed.

Notes
 The images are shown here scaled 
automatically by the projector.
  The image may be scaled differently

SCREEN REQUIREMENTS
Diagonal screen sizes
Screen sizes are sometimes specified by their diagonal size (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 into w\
idth and 
height, at various aspect ratios.   
2.35:1 (Scope) 
W = D x 0.92 H = D x 0.39
1.85:1 
W = D x 0.88 H = D x 0.47
16:9 = 1.78:1 (native aspect...

SCREEN REQUIREMENTS
Fitting the 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.
14:3 = 1.33:1
W = H x...

SCREEN REQUIREMENTS
Positioning the screen and projector
For optimum viewing, the screen should be a flat surface 
perpendicular to the floor. The bottom of the screen should 
be 1.2m (4 feet) above the floor and the front row of the 
audience should not have to look up more than 30° to see 
the top of the screen.
The distance between the front row of the audience and 
the screen should be at least twice the screen height and 
the distance between the back row and the screen...

CHOOSING A LENS
Choosing A Lens
A number of lenses are available. Which lens you choose will depend on th\
e screen size, image aspect ratio, projection distance and light 
output. In addition, each lens is available in two versions: High Bright\
ness and High Contrast.
The lenses available are listed below:
Lens
0.77 : 1 fixed lens
1.16 : 1 fixed lens
1.45 - 1.74 : 1 zoom lens

CHOOSING A LENS
Choosing a lens by calculation
For any screen size not listed above, or if you need to be more precise,\
 you can use the calculations below.
1. Identify the width of the image in pixels.
2. Calculate the throw ratio factor (TRF): 
3. Identify the screen width required.
4. Identify the throw distance required.
5. Calculate the throw ratio required.
6. Choose a lens with the required throw ratio from the list below. 
Check from the list that the lens chosen will...
