Aspect ratio
Fitting the image to the DMD
If the source image supplied to the projector is smaller than 1280 x 720 pixels, 
then the image will not fi ll the DMD. The following example shows how a number 
of common formats may be displayed.
Images displayed full width
Images displayed full height
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.

 Diagonal screen sizes
Screen sizes are sometimes specifi ed 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 (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)
4:3 = 1.33:1
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 = width
H = height

Fitting the image to the screen
It is important that your screen is of suffi cient 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 insuffi cient height or width, 
you will have to reduce the overall image size in order to display the full image on 
your screen.

Digital Projection TITAN HD-500, HD-250 User Manual  2. Installation
Positioning the screen and projector
For optimum viewing, the screen should be a fl at surface perpendicular to the fl oor. 
The bottom of the screen should be 1.2m (4 feet) above the fl oor 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 fl ipped 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 suffi cient 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
  The High Brightness lenses are 
recommended for the HD-500, 
for maximum light output.
  The High Contrast lenses are 
recommended for the HD-250, 
for maximum contrast.
  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, projection distance and light 
output.
The lenses available and their part numbers are listed below:
   High Brightness  High Contrast
0.63 : 1 fi xed lens  001-734   102-373
0.96 : 1 fi xed lens  001-735   102-835
1.2 - 1.44 : 1 zoom lens  001-736      102-374
1.44 - 1.8 : 1 zoom lens  001-737      102-375
1.8 - 2.4 : 1 zoom lens  001-738      102-376
2.4 - 3.6 : 1 zoom lens  001-739      102-377
3.6 - 5.6 : 1 zoom lens  001-740      102-378
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 fi xed. If, however, you are 
using commercially available image processing equipment, such as the Digital 
Projection VIP1000, you may be able to resize the image to fi t the DMD.
If the image does not fi ll 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 charts
For the screen sizes listed below, use the charts on the following pages, to choose 
the most suitable lens.
Full width images, including:
2.35:1 (Scope)  1280 x 544 pixels
1.85:1  1280 x 691 pixels
16:9 = 1.78:1 1280 x 720 pixels (native resolution)
Full height images
 A Throw ratio factor (TRF) has been applied to the following charts:
1.66:1 (Vista) 1195 x 720 pixels   TRF = 1.07
4:3 = 1.33:1 960 x 720 pixels    TRF = 1.33
5:4 = 1.25:1 900 x 720 pixels    TRF = 1.42
Method two: by calculation
See the calculations, on the page immediately following the lens chart.

Choosing a lens using the lens charts
Use the charts on this page and on the following pages to choose which lens best 
suits your application.
Full width images, including 2.35:1, 1.85:1 and 16:9 (native resolution)
example
For a screen width of 6m at a distance of 13m, the 1.8 - 2.4: 1 zoom lens would 
be best suited.
For the same screen size at a distance of 18m, the 2.4 - 3.6: 1 zoom lens would 
be best suited.
if you need to be more precise, then use the calculations on the page immediately 
following the lens charts. •
