Aspect ratio
Fitting the image to the DMD
If the source image supplied to the projector is smaller than 1400 x 1050 pixels, then
the image will not fill the DMD. The following example shows how a number of
common formats may be displayed.
Images displayed full height
Images displayed full width
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 Picture or
Geometry menus.
full height = 1050 pixels
5:4 = 1.25:1 = 1313 pixels

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).
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
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)
4:3 = 1.33:1 (native aspect ratio)
W = D x 0.8in (D x .02m)H = D x 0.6in (D x .015m)
5:4 = 1.25:1
W = D x 0.78in (D x .02m)H = D x 0.625in (D x .016m)
Notes
D = diagonal (inches)
W = widt h
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 full image on
your screen.

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 it s 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.

Notes
For more information about
Throw ratio factor (TRF), see
Useful lens calculations, later
in this section.
Choosing a lens
A number of lenses are available for use with the projector. Which lens you choose
will depend on the screen size, image aspect ratio and projection distance.
If you are simply connecting the output of a camera or computer directly to the
projector, then the image size (in pixels) may well be fixed. If, however, you are
using commercially available image processing equipment, such as the Digital
Projection MMS 1000 or VIP1000, you may be able to resize the image to fit the
DMD.
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 for by applying a Throw ratio factor.
Method one: using the lens chart
For the screen sizes listed below, use the charts on the following page, to choose
the most suitable lens.
any full width image, including:
4:3 = 1.33:11400 x 1050 pixels (native resolution)
1.66:1 (Vista)1400 x 843 pixels
16:9 = 1.78:11400 x 788 pixels
1.85:11400 x 757 pixels
2.35:1 (Scope)1400 x 596 pixels
full height image
A Throw ratio factor (TRF) of 1.07 would need to be applied, for the charts to be
correct for the following image (multipy the required screen width by 1.07 before
consulting the charts):
5:4 = 1.25:11313 x 1050 pixels
Method two: by calculation
See the calculations, on the page immediately following the lens chart.

Digital Projection TITAN sx+-500 User Manual2. Installation
Notes
For a 5:4 full height image,
measuring 1313 x 1050 pixels:
A Throw ratio factor (TRF) of
1.07 would need to be applied
for the chart to be correct.
(ie: multiply the required screen
width by 1.07 before consulting
the chart)
The lenses available and their
part numbers are listed below:
0.73 : 1 fixed lens 105-607
1.2 : 1 (3 - 15m) fixed lens 105-608

1.2 : 1 (1.2 - 2.0m) fixed lens 105-609
Lens chart
Use the chart below to choose which lens best suits your application.
example
•For a screen width of 12m at a dist ance of 35m, the 2.77 - 4.51: 1 zoom lens
would be best suited.
•For the same screen size at a distance of 60m, the 4.51 - 7.53: 1 zoom lens
would be best suited.

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 lenses available and their
part numbers are listed below:
0.73 : 1 fixed lens
105-607

1.5 - 2.02 : 1 zoom lens 105-610
2.02 - 2.77 : 1 zoom lens 105-611
2.77 - 4.51 : 1 zoom lens 105-612
4.51 - 7.53 : 1 zoom lens 105-613
Method two: Choosing a lens by calculation
For any screen size not listed above, or if you need to be more precise, then use the
calculations below.
•Identify actual width of the image in pixels.
•Calculate the Throw Ratio Factor:TRF =
DMD width (1400)
Image width in pixels
•Identify the screen width required.
•Identify the throw distance required.
Throw distance calculations are based on the distance from the outer end of the
lens, which will vary from lens to lens. Once a lens has been chosen, the figures
can be checked using the more accurate figures given on the next page.
•Calculate the throw ratio required.Throw ratio =
Throw distance
Screen width x TRF
•Choose a lens with the required throw ratio from the list to the right.
•Check from the lens charts or the specification, that the lens chosen has a
sufficient throw range.
example
•An image, 1024 x 768 pixels, screen width 6.5m, throw dist ance 18m from the
outer end of the lens.
•Throw Ratio Factor (TRF) =
1400 = 1.37
1024
•Throw ratio required =
         18 = 2.02
6.5 x 1.37
•Choose the 2.0 - 2.77  zoom lens (105-611)

Lens extension is measured
when the lens is focussed at

other focus settings, the
extension could be up to 10mm
less
Useful lens calculations
The following lens calculations may be useful:
Throw ratio =
Throw distance
Screen widt h
Throw ratio factor (TRF) =
DMD width in pixels =1400
image width in pixels image wid th in pixels
Therefore:
Screen widt h =
Throw distance (from outer end of lens)
Throw ratio x TRF
Throw distance = Screen wid th x Throw ratio x  TRF
The throw distance calculated above is to the outer end of the lens. For each lens,
the nominal distance between the front of the projector and the outer end of the lens
(lens extension) will be as listed below:
lens extension
0.73 : 1 fixed lens 105-607 204mm (8.0in)
1.2 : 1 (3 - 15m) fixed lens 105-608 268mm (10.6in)
1.2 : 1 (1.2 - 2.0m) fixed lens 105-609 268mm (10.6in)

Notes
Make sure the rear lens cap is
removed, before fitting the lens.
Make sure the front lens cap is
removed, before switching on
the projector.
Be careful not to scratch the
lens surfaces. If you do
accidentally touch a lens, then
clean the surface using a lens
paper.
The lens release lever should
always be set to the locked
position to prevent the lens
from falling out. Lens release

Fitting the lens
•Turn the lens release lever anti-clockwise so that it is pointing upwards, to open
the lock.
•Remove the rear lens cap from the lens.
•Insert the lens into the lens aperture, making sure that the plug on the drive
mechanism engages with the socket on the front of the projector, and that the
lens is pushed firmly into place.
•Turn the lens release lever clockwise to lock the lens in place. When the lock is
fully closed, the lever should feel loose.
