Try aligning the two grid patterns 
Adjust zoom and offset on the top projector to precisely move its test pattern display 
on to the bottom test pattern. When properly aligned, all red/green grid lines in the 
combined image will turn yellow. 
 If all lines are well aligned, skip to Step 7 to lock all stacking mounts. 
 If alignment needs improvement, proceed with the next step. 
Align the centerlines of the grid 
Turn the two rear stacking mount wheels 
to move the top projector as necessary for 
well-aligned centerlines. Use a 
screwdriver in the holes around the rim 
of each adjusting wheel for better 
leverage and control. 
HOW TO MOVE THE IMAGE: Turned 
independently, each stacking mount acts 
as a pivot point for the opposite edge of 
the display (Figure 2.15). For example, 
turn the right mount to tilt the left portion 
of the image up or down, and turn the left 
mount to tilt the right portion of the 
image up or down. Turn the mounts 
together to raise or lower the top image 
like an offset adjustment, or turn the front 
stacker. 
IF THE CENTER LINES FORM AN “X”: This indicates that the projectors (and images) 
are slightly tilted in relation to one another. Turn one mount to raise one side, and/or 
turn the other mount to lower other side. See Figure 2.15. 
IF THE CENTER LINES ARE PARALLEL BUT MISALIGNED:  
 If centerlines are out by the same amount from top 
and bottom – use offsets (on top projector) to bring 
the centerlines into alignment. 
 
 
 If centerlines are parallel but 
others are not, turn the front 
stacking mount wheel to bring the 
centerlines into alignment.

Align the edges of the grid 
With centerlines aligned, adjust zoom (top projector) to align the edges of its image 
with the other image. Then adjust focus. When aligned, all lines from the combined 
red/green grids will be yellow. 
Secure all stacking wheels and leg nuts 
 WARNING  
Critical Safety Procedure.

Front Screen Installations 
While there are two basic screen types, flat and curved, generally flat screens are 
recommended for this projector (Figure 2.17). Flat screens offer a gain of about one 
with a viewing angle just less than 180°. Incident light reflects equally in all 
directions so the audience can see the display from various angles. Because of the 
low gain, flat screens are most effective when ambient lighting is reduced, although 
this difference may be negligible given the high brightness output from this projector. 
 
Figure 2.17. Audience Coverage with Flat Screen 
NOTE: Lenses for this projector are designed primarily for use with flat screens, but 
the projector depth-of-field range allows the lens to be focused on curved screens as 
well. While focus remains sharp in the corners, there may be significant pincushion 
distortion, primarily at the top of the screen. 
Rear Screen Installations 
There are two basic types of rear screens: diffused and optical. A diffused screen has 
a surface that spreads the light striking it. Purely diffused screens have a gain of less 
than 1. The main advantage of the diffused screen is its wide viewing angle, similar 
to that of a flat screen for front screen projection. Optical screens take light from the 
projector and redirect it to increase the light intensity at the front of the screen. This 
increase at the front reduces the intensity in other areas. A viewing cone, similar to 
that of a curved front screen installation, is created. 
To summarize, optical screens are better suited for brightly lit rooms where the 
audience is situated within the viewing cone. Diffused screens may be better suited 
when a wide viewing angle is required but there is low ambient room lighting. 
Choose a screen size, which is appropriate for your lens and application. Keep in 
mind that if the projector will be used to display text information, the image size 
must allow the audience to recognize all text clearly. The eye usually sees a letter 
clearly if eye-to-text distance is less than 150 times the height of the letter. Small text 
located too far from the eye will likely be illegible at a distance no matter how 
sharply and clearly it is displayed.   Screen T

To fill a screen with an image, the aspect ratio of the screen should be equal to the 
aspect ratio of the image (expressed as the ratio of its width to its height). Standard 
video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR 
output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the screen 
must be at least 13.3 feet (4m). 
Ideally, to fill a screen with an image, the aspect ratio of the screen should be equal to 
the aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of 
its width to its height such as a 4:3 aspect. Standard video from a VCR has a 4:3 
aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10-
foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m). 
Aspect ratio describes the proportion of the screen and is expressed as the ratio of 
width to height, such as “4:3” or “5:4”. Although image size and image aspect ratio 
can both be adjusted quickly through projector software, it is still a good idea to 
choose a screen aspect ratio that is most appropriate for your intended applications. 
Ideally, to exactly fill a screen with an image, the aspect 
ratio of the screen should correspond to the aspect ratio of 
the image, which depends on the source in use. For 
example, standard video from a VCR has a 4:3 ratio 
(approximately), whereas a high-resolution graphics 
signal typically has a 5:4 aspect ratio. By default, images 
from your projector will be as large as possible and will 
maintain their aspect ratio. 
The SXGA+ (1400 x 1050) aspect ratio for the Roadster 
S+ and Mirage S+ models are 4:3 (Figure 2.18) and the 
HD (1920 x 1080) aspect ratio for the Roadster HD and Mirage HD models is 16:9. 
The high brightness of this projector is well suited for locations where ambient 
lighting might be considered less than ideal for projection. A typical room with 
ceiling lights and windows rarely requires special attention. Contrast ratio in your 
images will be noticeably reduced only if light directly strikes the screen, such as 
when a shaft of light from a window or floodlight falls on the image. Images may 
then appear washed out and less vibrant.  
In general, avoid or eliminate light sources directed at the screen.   Screen As

Other considerations and tips that can help improve your installation: 
 Keep the ambient temperature constant and below 35°C (95°F). Keep the 
projector away from heating and/or air conditioning vents. Changes in 
temperature may cause drifts in the projector circuitry that may affect 
performance. 
 Keep the projector away from devices that radiate electromagnetic energy such 
as motors and transformers. Common sources of these include slide projectors, 
speakers, power amplifiers, elevators, etc. 
 Choose the best screen size for the application. Since more magnification reduces 
brightness, use a screen size appropriate for the venue but not larger than 
required. Installing a large screen in a small room is similar to watching 
television at a close range; too large a screen can overpower a room and interfere 
with the overall effect. A good rule of thumb is to be no closer than 1.5 times the 
width of the screen. 
 
Throw distance 
Throw distance is the distance measured from your projector’s front feet 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 a desired screen 
size and if your image will be of the right size for your screen.  
You can quickly estimate the throw distance by taking the horizontal width of the 
screen and multiplying it by the lens throw ratio. The result of this calculation tells 
you roughly how far back the projector should be positioned from the screen in order 
to project a focused image large enough to fill the screen.  
 
For example: Screen Width = 10 feet 
Lens Type is 0.7:1 
Throw Distance (TD) = 10 feet x 0.7 = 7 feet 
IMPORTANT: Use the lens and screen size to calculate the precise throw distance 
using the tables provided in the Dealer Section of the Christie Website, PN 020-
100298-xx. Due to lens manufacturing tolerances for lens focal length, actual throw 
distance and vary ±5% between lenses with the same nominal throw ratio.

THE VERTICAL POSITION of the projector in relation to the screen also depends on the 
size of the screen and the lens type. Correct vertical position helps ensure that the 
image will be rectangular in shape rather than keystoned (having non-parallel sides) 
and that image focus and brightness both remain optimized.  
If necessary, vertical position of the image can be offset—that is, moved up or down 
in relation to lens center—by using the motorized offset function. Starting with no 
offset, the image from this projector can be moved up or down by a maximum 
distance of 525 pixels for SXGA+ resolution and 643 pixels for HD and WUXGA 
resolution, resulting in the entire image (more for HD/WUXGA) being displayed 
above or below lens center. See Table 2.1 and Figure 2.19.  
NOTE: Not applicable for the fixed lens. 
THE HORIZONTAL POSITION of the image can be offset—that is, shifted left or right 
of lens center—by using the motorized offset function. Starting with no offset, the 
image from this projector can be moved left or right by a maximum distance of 350 
pixels for SXGA+ resolution and 403 pixels for HD and WUXGA resolution, 
resulting in approximately 75% of the image displayed to one side of lens center. See 
Table 2.1 and Figure 2.20.

NOTES:  
1) If the image becomes keystoned or exhibits 
uneven brightness, the projector may simply be 
too high or low in relation to the screen. 
 2) Recommended offset ranges can be 
exceeded, however this may affect image 
quality.  
3) Simultaneous horizontal and vertical offset 
limits the adjustment range of each.  
4) Offset can vary by ±7% and may be affected 
by the degree of zoom currently in use. 
 
 
 
There are several methods for mounting the projector. Depending on your chosen 
installation, one method may be more suitable than another. In typical front and rear 
screen installations the projector can be mounted to a secure and level surface, such 
as a table or cart. Carts are useful when the projector has to be moved during a 
presentation or from site to site. It is recommended you lock the wheels on a cart, 
when it’s in position, to prevent someone from accidentally moving it during a 
presentation.

CEILING MOUNT - The projector can also be inverted and suspended from the ceiling 
using a specially designed ceiling mount fixture. This type of mounting is 
recommended for fixed installations and for those that want the projector out of plain 
view or have a limited amount of space for projector and audience. For more 
information, contact your dealer. 
 Use only the CHRISTIE approved ceiling mount kit designed for your 
projector. Refer to the installation instructions and safety guidelines 
provided in the kit.
 
 
The projector can be rotated and mounted at any vertical angle—i.e., you can tilt the 
face of the projector up or down as much as desired for your installation. Side-to-side 
tilt, however, must not exceed 15° (Figure 2.21). Keeping the projector fairly level in 
this manner ensures that the lamp axis is level, and is required for safe and reliable 
lamp operation. Always vent exhaust air away from the lens. 
 
Figure 2.21. Vertical and Horizontal Tilt Ranges 
 
In rear screen applications (Figure 2.22) where space 
behind the projector is limited, a mirror may be used 
to fold the optical path. The position of the projector 
and mirror must be accurately set. Consult your 
dealer or Christie for details. 
 
 
Sources connect to the Input Panel located on the rear of the projector. As shown in 
Figure 2.23. 
The upper right corner (
INPUT 1) typically accepts an RGB signal from an external 
analog RGB source, or it can also be used for YPbPr signals or additional video 
sources. Just beside these BNCs, the DVI-I connector (
INPUT 2) accepts digital or 
analog display signals from a computer. Connect analog composite video at 
INPUT 3 
or S-video at 
INPUT 4 from devices such as VCRs, laser disc players or DVD players.    Tiltin

Figure 2.23. Input Panel 
INPUT 1 consists of five BNCs (connectors) for linking to a variety of RGB sources 
such as a PC, Mac, DEC, Sun, SGI, and others. This projector supports multiple sync 
types with RGB signals: sync-on-green, composite sync, and separate H & V syncs. 
NOTE: Depending on your source, you may need a custom adapter cable with BNC 
connectors at the projector end and a different type of connector at the other (such as 
a 15-pin “D” connector for some computer sources). Contact your dealer for details. 
Connect the 
SYNC BNC input(s) first. Then connect the red, green, and blue source 
outputs to the 
RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses 
sync-on-green, only the red, green, and blue connections are required. If the source 
provides a composite sync output, connect it to the 
SYNC input labeled HOR/COMP. If 
the source provides separate horizontal and vertical sync outputs, connect horizontal 
sync to the 
SYNC input labeled HOR/COMP, and connect vertical sync to SYNC input 
labeled 
VERT. See Figure 2.24, below.
