Installation Considerations
Proper installation of your projector will ensure the quality of your display. Whether you are 
installing a projector temporarily or permanently, you should take the following into account 
to ensure your projector performs optimally.
Installation TypeChoose the installation type that best suits your needs: front or rear screen, floor mount or 
inverted mount. 
Table 3-2 compares these various installation methods. 
Ambient LightIn general, minimize or eliminate light sources directed at the screen. Contrast ratio in your 
images will be noticeably reduced 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.

Throw DistanceThrow 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 a desired screen size and if your image will 
be the right size for your screen.
You can quickly estimate the throw distance by taking the width of the screen and 
multiplying it by the lens throw ratio; see 
Figure 3-1. 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.
Figure 3-1. Estimating Throw Distance
Table 3-3 gives the throw ratios for the Vision 65/75, Vision 65/75/CineWide and  
Vision 65/75/CineWide with AutoScope.

Vertical and Horizontal 
Position 
Proper placement of the projector relative to the screen will yield a rectangular, 
perfectly-centered image that completely fills the screen.
Ideally, the projector should be positioned perpendicular to the screen and in such a way 
that the lens center is aligned with either the top or bottom edge of the screen area, and 
centered horizontally. See 
Figure 3-2.

Vertical Lens ShiftYou can use the lens shift (LENS) controls on the projector remote to center the image on the 
screen. Vertical lens shift is generally expressed as a percentage of the screen height, as 
shown in 
Figure 3-3.
Figure 3-3. Vertical Lens Shift (Example Only)
The Vision 65/75 provides up to 35% of vertical lens shift above and up to 50% of 
vertical lens shift below the screen center. For example, with a 100 x 56-inch (16:9) screen, 
you can shift the image up to 19.60 inches (0.50
 meters) above or 28.00 inches (0.71 meters) 
below the screen center.
➤
1. With no vertical lens shift, the lens center and screen center are aligned 
with each other.
2. Vertical lens shift figures are for ceiling mount configurations. 
 For floor installations (where the projector is upright), reverse the 
up/down vertical lens shift percentages.

Folded OpticsIn rear-screen applications where space behind the projector is limited, a mirror may be used 
to fold the optical path, as shown in 
Figure 3-4. The position of the projector and mirror must 
be accurately set. If you are considering this type of installation, contact your dealer for 
assistance.
Figure 3-4. Folded Optics
Other ConsiderationsOther 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, which 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 and elevators.

Installing the Optional 
CineWide Lens Mount
If you are installing a standard (non-CineWide) Vision 65/75, skip this step and proceed with 
Mounting the Vision 65/75 (page 25). 
If you are installing a CineWide projector equipped with a prismatic 
(Whitney) anamorphic lens, proceed with 
Installing the Fixed CineWide 
Base Plate (Prismatic Lens) (page 23). 
 
If you are installing a Vision 65/75/CineWide with a cylindrical 
(Rainier II or McKinley) anamorphic lens, proceed with 
Installing 
the Fixed CineWide Base Plate (Cylindrical Lens) (page 24).  
 
If you are installing a Vision 65/CineWide with AutoScope or Vision 75/CineWide with 
AutoScope, proceed as follows to install the AutoScope lens motor. 
Screen
Mirror
1.  Do not install the CineWide lens yet, only the fixed CineWide base plate 
or AutoScope lens motor. You will install the CineWide lens after you 
install the projector and adjust the primary lens. 
2.  Some components shipped with your projector may differ slightly 
from what is shown in these instructions.

Install Ceiling Mount Adapters/Projector Stands: For ceiling installations, these brackets 
bring the mounting points for the projector mounting plate (included with the projector 
ceiling mount kit) from the bottom of the projector up and around the AutoScope lens motor 
housing. For floor installations (where the projector is upright), the adapters allow the 
projector to lie flat on the mounting surface.
Using the four (4), supplied M6 x 12mm Flat-Head Phillips screws (item #6), attach the 
AutoScope Ceiling Mount Adapters/Projector Stands (items #4 and
 #5) to the projector as 
shown in 
Figure 3-6.
