Examples of 4:3 images displayed with different aspect ratio settings
The 4:3 setting is best, unless there is some specific reason for wantin\
g the smaller 
Native image, for instance, to maintain the same scale as other images f\
rom the 
same source.
If you are using an anamorphic lens, the 4:3 Narrow setting should be us\
ed. The 
lens will stretch the image to the correct width.
Examples of 2.35:1 images displayed with different aspect ratio 
settings
The 16:9 setting is best, unless there is some specific reason for wanti\
ng the 
smaller Native image, for instance, to maintain the same scale as other \
images from 
the same source.
If you have an anamorphic lens, the Theaterscope setting would be a much better 
option. Because it uses the whole of the DMD, it will be a much brighter\
 image than 
the letterboxed options shown above, and will fill a wider screen if thi\
s is available.
Notes
 The 4:3 image shown here has 
far fewer pixels than the 1920 x 
1080 of the DMD. Your image 
may be different.
 If you are using an  anamorphic  
lens, you will need to use the 
4:3 Narrow setting to correct the 
image.
 The 2.35 image shown here has 
far fewer pixels than the 1920 x

 To take advantage of the 
Theaterscope setting, you 
MUST have an anamorphic 
lens.

Diagonal screen sizes
Screen sizes are sometimes specified by their diagonal size (D) in inc\
hes. 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 inc\
hes into 
width and height, at various aspect ratios.
2.35:1 (Scope) 
W = D x 0.92in (D x .023m) H = D x 0.39in  (D x .01m)
1.85:1 
W = D x 0.88in (D x .022m) H = D x 0.47in  (D x .012m)
16:9 = 1.78:1 (native aspect ratio) 
W = D x 0.87in (D x .022m) H = D x 0.49in  (D x .0125m)
1.66:1 (Vista) 
W = D x 0.86in (D x .022m) H = D x 0.52in  (D x .013m)
16:10 = 1.6:1 
W = D x 0.85in (D x .022m) H = D x 0.53in  (D x .014m)
4:3 = 1.33:1 
W = D x 0.8in (D x .02m) H = D x 0.6in  (D x .015m)
D = diagonal (inches)
W = width
H = height

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 f\
ull image on 
your screen.

Positioning the screen and projector
Optimum viewing position
For optimum viewing, the screen should be a flat surface perpendicular t\
o the floor. 
The bottom of the screen should be 1.2m (4 feet) above the floor and t\
he front row 
of the audience should not have to look up more than 30° to see the t\
op 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 section 
4. Using the menus, Image 
menu) 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.

Screen size vs throw distance
Throw distance is the distance measured from the front of the projector \
to the 
screen. This is an important calculation in any projector installation as it det\
ermines 
whether or not you have enough room to install your projector with the d\
esired 
screen size, and if your image will be the right size for your screen.
Calculating screen width and throw distance
Throw Distance  =  Screen Width  x  Lens Throw Ratio
Screen Width  = Throw Distance   
        Lens Throw Ratio
Three models of the projector are available, fitted with the following l\
enses:
     Throw Ratio   Focus range
Fixed lens   0.73:1      to be confirmed
Short-throw lens 1.56–1.86:1 zoom  2–7m (6.6 - 23ft)
Long-throw lens 1.85–2.40:1 zoom  2.5–10m (8.2 - 32.8ft)
Two optional converter lenses are available, which modify the throw ratio\
s as shown 
below:
     0.8x converter   1.25x converter
Short-throw lens 1.25–1.49:1    1.95–2.33:1
Long-throw lens 1.48–1.92:1    2.31–3:1
These throw ratios are correct for images that fill the full width of th\
e DMD. For 
images that do not fill the full width, the throw ratio will be larger. For 4:3 images, 
the throw ratio is increased by a factor of 1.33. The effect of this can be seen on the 
lens charts on the following pages.
•

•
•
Notes
 For more information about the 
relationship between screen 
size, throw distance and 
converter lenses, see the Lens 
charts on the following pages.
 Do not confuse the focus range 
with the zoom range:
  - the focus range is the distance 
over which the image can be 
focused using the focus ring.
 - the zoom range is the range 
over which the throw ratio can 
be changed using the zoom 
ring.
 The converter lens is not 
physically compatible with the 
Fixed lens.

Notes
 Note that for the long throw 
lens, there is some overlap 
between the range available 
using the converter lenses and 
that using no converter lens.

You can display a 4:3 image with a screen width of 3m at a distance of 6m\

for a screen width of 2m, you will need to use the 1.25x converter lens.\

Shifting the image
Ideally, the projector should be positioned perpendicular to the screen.
The normal position for the projector is at the centre of the screen. Ho\
wever, with 
the zoom lenses, you can set the projector above or below the centre, or\
 to one 
side, and adjust the image using the Lens shift controls on the top of the projector 
to maintain a geometrically correct image.
The maximum range available with no distortion is dependent on which zoo\
m lens is 
used. The tables below show the maximum range for images that fill the DMD. Fo\
r 
images which do not use the full height or width, extra shift may be pos\
sible, up to 
the limit of the lens mount movement.

The image can be shifted by up to:
± 0.6 of the height of a full screen image (known as 120% shift)
± 0.15 of the width of a full screen image (known as 30%)
It is physically possible to shift the lens further than this, however t\
here will be some 
distortion of the image beyond the ranges specified above.

Mounting the projector
The four adjustable feet under the chassis allow the projector to be low\
ered onto a 
flat surface without any danger of hands being trapped between the botto\
m frame 
and the surface.
Ceiling mounting
The projector is designed to be used on a flat surface, but it can be su\
spended 
from a ceiling. Three M4 mounting holes with a 0.7mm pitch are provided under the 
projector to allow bolting to a ceiling mounting plate.
Cine 230/260
Cine 400
To use the projector upside down, set Ceiling mode to On, in the System menu, to 
invert the image.
Notes
 BEFORE INSTALLING THE 
PROjECTOR, READ ALL THE 
WARNINGS BELOW  AND 
ALL THOSE IN IMPOr TANT 
INFOrMATION AT THE 
FRONT OF THIS MANUAL.
  The projector weighs 
approximately 13 kg (29 lbs). 
Use safe handling techniques 
when lifting the projector.
 Make sure that the surface, 
ceiling or rigging that is 
to support the projector is 
capable of supporting the 
weight of the projector.
 Backup safety chains or 
wires should always be 
used with ceiling mount 
installations.
 Do not tilt the projector more 
than  ±12° in either direction 
when in use, as this may 
cause serious lamp failure, 
damage the lamp module 
and cause extra cost on 
replacement.
