Installation precautions
The projector must be installed only by suitably qualified personnel, in
accordance with local building codes.
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 projector weighs approximately 15 kg (33 lbs). Use safe handling
techniques when lifting the projector.
Do not stack more than three projectors.
When stacking projectors, the stack MUST be vertical, to ensure that
the stresses are distributed to all four chassis corners.
Before installation, make sure that the surface, ceiling or rigging that is
to support the projector is capable of supporting the combined weight
of all the projectors.
Notes
Backup safety chains or wires should always be used with ceiling
mount installations.
Do not place heavy objects on top of the projector chassis. Only the
chassis corners are capable of withstanding the weight of another
projector.
Do not drop or knock the projector.
Place the projector in a dry area away from sources of dust, moisture,
steam, smoke, sunlight or heat.
Operation and configuration precautions
Software update should NOT be carried out except by, or with the
supervision of, Digital Projection Service personnel.

Screen requirements
Aspect ratio
Fitting the image to the DMD
The projector uses a DMD (Digital Mirror Device) to create the image that is
projected onto the screen. The resolution of the DMD in this projector is 1920 x
1080 pixels, or to put it another way, its aspect ratio is 16:9.
1920 pixels
1080 pixels
16 units
If the source image supplied to the projector has a different aspect ratio from this,
or even if it has the same aspect ratio but fewer pixels, then the image will not fill
the DMD. The projector therefore needs to scale the image.
9 units
Notes
The projector has five aspect ratio settings, so that you can choose the one that is
most suitable for your image source. The settings are:
16:9 the image is scaled to fill the DMD (and thus, a 16:9 screen).
Theaterscope the image is scaled such that a 2.35:1 image will be displayed
at the correct aspect ratio when the projector is fitted with an
anamorphic lens. Thus an image with an aspect ratio of 2.35:1
can be displayed using the full 16:9 resolution of the DMD.
4:3 the image is scaled to fit a 4:3 screen, using the full height of the
DMD.
4:3 Narrow to be used for 4:3 images in combination with an anamorphic
lens. The image is scaled to fit the DMD vertically, but squeezed
horizontally such that the lens will stretch it to the correct ratio.
Native the image is displayed with no scaling, at its original resolution, in
the centre of the screen.
Examples of 16:9 images displayed with different aspect ratio settings
For more information about
changing the Aspect ratio
setting, see Using the control
keys and Using the menus
in section 4. Controlling the
Projector.
The 16:9 image shown here has
far fewer pixels than the 1920 x
1080 of the DMD. Your image
may be different.
16:9
Note that, as the aspect ratio of the image matches that of the DMD, the 16:9
setting is best, unless there is some specific reason for wanting the smaller image,
for instance, to maintain the same scale as other images from the same source.
Native

Examples of 4:3 images displayed with different aspect ratio settings
4:3
The 4:3 setting is best, unless there is some specific reason for wanting the smaller
Native image, for instance, to maintain the same scale as other images from the
same source.
If you are using an anamorphic lens, the 4:3 Narrow setting should be used. The
lens will stretch the image to the correct width.

Notes
The 4:3 image shown here has
far fewer pixels than the 1920 x

may be different.
If you are using an anamorphic
lens, you will need to use the
4:3 Narrow setting to correct the
image.
Examples of 2.35:1 images displayed with different aspect ratio
settings
16:9 Native
The 16:9 setting is best, unless there is some specific reason for wanting 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 this is available.

The 2.35 image shown here has

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 inches. When
dealing with large screens and projection distances at different aspect ratios, it is
more convenient to measure screen width (W) and height (H).
W = width
H = height
D = diagonal (inches)
The example calculations below show how to convert diagonal sizes in inches 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)
Notes
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)

Digital Projection M-Vision Cine LED User Manual 2. Installation
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.

Positioning the screen and projector
Optimum viewing position
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 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 determines
whether or not you have enough room to install your projector with the desired
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
Notes
For more information about the
relationship between screen
size, throw distance and
converter lenses, see the Lens
charts on the following pages.
Three models of the projector are available, fitted with the following lenses:
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 ratios 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 the 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.
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 lenes are not
physically compatible with the
Fixed lens.
The 0.8:1 conversion lens
introduces up to 4% bow
distortion. Digital Projection
recommends caution when
using this lens
