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 TheaterScope, the black lines will disappear but the image will stretch vertically t\
o reach the top and bottom of 
the DMD™:
An anamorphic lens will stretch the image horizontally, restoring the original 2.35 ratio:

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 
if the aspect ratio is set differently in 
the 
Main menu.

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 ratio for 1080p projectors) 
W = D x 0.87 H = D x 0.49
1.66:1 (Vista) 
W = D x 0.86 H = D x 0.52
Notes
D = diagonal
W = width
H = height

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 1.33, H = W x 0.75
216:10 = 1.6:1
W = H x 1.6, H = W x 0.625
31.66:1 (Vista)
W = H x 1.66, H = W x 0.6
416:9 = 1.78:1 (native aspect ratio)
W = H x 1.78, H = W x 0.56
51.85:1 (Flat)
W = H x 1.85, H = W x 0.54
62.35:1 (Scope)
W = H x 2.35, H = W x 0.426

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 should 
be a maximum of 8 times the screen height. The screen 
viewing area should be within a 60° range from the face of 
the screen.
Notes
 The projector should be installed 
as close to the power outlet as 
possible.
  The power connection should be 
easily accessible, so that it can 
be disconnected in an emergency.
  Ensure that there is at least 
30cm (12in) of space between the 
ventilation outlets and any wall, 
and 10cm (4in) on all other sides.
  Do not install the projector close 
to anything that might be affected 
by its operational heat, for 
instance, polystyrene ceiling tiles, 
curtains etc.
 The image can be flipped for rear 
projection (see the  Operating 
Guide ) and displayed without the 
need for extra mirrors or equipment.
  However, you must ensure that 
there is sufficient distance behind 
the screen for the projector to be 
correctly located.
  Rear installation is generally more 
complicated and advice should be 
sought from your local dealer before 
attempting it.

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
1.74 - 2.17 : 1 zoom lens
2.17 - 2.90 : 1 zoom lens
2.90 - 4.34 : 1 zoom lens
4.34 - 6.76 : 1 zoom lens
If the image does not fill the full width of the DMD™, this effectively increases the throw ratio of the lens. This can be corrected by applying a 
throw ratio factor (TRF).
To choose a lens for your projector, you can either apply a lens calculation, or use the lens charts provid\
ed here for quick reference.
Notes
 The High Brightness lenses are 
recommended for the HB model, for 
maximum light output.
  The High Contrast lenses are 
recommended for the HC model, for 
maximum contrast.
 For more information about throw 
ratio factor (TRF), see Choosing 
a lens by calculation  later in this 
section.
  For information about individual lens 
part numbers, see Appendix A at 
the end of this document.

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 work at the throw distance\
 required.
Throw ratioThrow distance range
0.77 : 1 fixed lens1.3 - 2.5 m (4.3 - 8.2 ft)
1.16 : 1 fixed lens1.4 - 6.2 m (4.6 - 20.3 ft)
1.45 - 1.74 : 1 zoom lens1.8 - 9.3 m (5.9 - 30.5 ft)
1.74 - 2.17 : 1 zoom lens2.2 - 11.8 m (7.2 - 38.7 ft)
2.17 - 2.90 : 1 zoom lens2.7 - 15.4 m (8.9 - 50.5 ft)
2.90 - 4.34 : 1 zoom lens3.6 - 22.5 m (11.8 - 73.8 ft)
4.34 - 6.76 : 1 zoom lens5.5 - 35 m (18 - 115 ft)
Notes
 The throw ratio for a particular lens 
is fixed, but assumes that the image 
fills the width of the DMD.
  For images that do not fill the width 
of the DMD, the throw ratio is 
effectively increased. To correct for 
this in these calculations, a throw 
ratio factor (TRF) is used.
 The DMD width is 1920.
 For information about individual lens 
part numbers, see Appendix A at 
the end of this document.
