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 and screen center are aligned with each other, as shown in 
Figure 3-2.
Figure 3-2. Projector Placement
Vertical and Horizontal 
Lens Shift
If it is not possible to align the projector and screen as shown in Figure 3-2, you can use 
the lens shift controls to center the image on the screen. Lens shift is generally expressed 
as a percentage of the screen height or width, as shown in 
Figure 3-3 and Figure 3-4.

Table 3-4 lists the lens shift limits for each available VX-22d lens, as percentages and 
absolute measurements with a 100 x 56 inch (1.78:1) screen.  
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 3-5. The position of the projector and 
mirror must be accurately set. If you are considering this type of installation, contact your 
dealer for assistance.

Notes: 
1. With no vertical or horizontal lens shift, the lens center and screen center are aligned with each 
other.
2. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of 
the screen width.
3. Vertical lens shift figures apply to ceiling mount configurations. For floor installations 
(where the projector is upright), reverse the up/down vertical offset percentages.

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 Primary 
Projection Lens 
The projection lens is shipped separately from the projector. To install it, proceed as 
follows:
1. Loosen the captive Phillips screw at the 
top of the Projector Front Jewelry.
 
 
 
 
 
 
 
 
 
 
 
 
 
2. Remove the jewelry.

4. Remove the Rear Lens Cap.  
 
 
 
 
 
 
 
 
 
 
 
5. Hold the lens assembly with the motor 
facing the upper-right corner of the 
Lens Cavity. Carefully insert the back 
of the lens assembly into the hole in the 
lens flange. 
 
 
DO NOT PUSH THE LENS ASSEMBLY 
ALL THE WAY IN. Only push the lens 
assembly in far enough so that the front 
of the lens motor is clearly behind the 
projector chassis cover.
6. Carefully rotate the lens assembly 45 
degrees clockwise until the motor 
socket connector is aligned with the 
connector on the flange. Then, gently 
push the lens assembly in until it is 
seated flush against the flange and the 
connectors have seated.

7. Lock the lens in place by turning the 
Lens Locking Nut (to the left of the lens) 
180 degrees counter-clockwise. (Use a 
6.0mm hex wrench.) 
 
 
 
 
 
8. Replace the Lens Cavity Front Cover.
9. Reattach the Projector Front Jewelry by sliding the top down onto the two retaining 
dowels. Tighten the Phillips screw at the top of the projector to secure it. 
10. Remove the Front Lens Cap. 
3.5 
Installing the Optional 
CineWide/AutoScope 
Lens Motor
If you are installing a VX-22d with the optional CineWide with AutoScope system, proceed 
as follows to install the AutoScope lens motor.
Remove Projector Front 
Feet
Place the projector upside down on a 
blanket or other soft surface. Loosen and 
remove the two front feet on the projector.
Make sure to route the wire harness in its original position and away 
from the moving lens stages and Motor Assembly, to prevent 
unexpected disconnection or lens damage. 
 
Caution
1. Do not install the CineWide lens yet, only the 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. 
3. The anamorphic lens mounting kit is partially pre-assembled at 
the factory – the AutoScope lens motor and lens mounting 
assemblies are both fully assembled.

Install Ceiling Mount 
Extension Brackets 
If you are installing a VX-22d/CineWide with AutoScope, use the supplied hardware to 
attach the ceiling mount extension brackets to the bottom of the projector as shown in 
Figure 3-6. 
For ceiling installations, these brackets bring the mounting points for the projector 
mounting plate (included with the ceiling mount kit) from the bottom of the projector up 
and around the lens motor housing. For floor installations (where the projector is upright), 
the brackets allow the projector to lie flat on the mounting surface.

3.6 
Mounting the VX-22d
There are several methods for mounting the projector. Depending on your chosen 
installation, one method may be more suitable than another. 
Floor Mounting (Upright)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 moving a projector during a 
presentation or from site to site. If possible, lock the wheels when it’s in position to prevent 
it from being moved during a presentation.
Ceiling Mounting 
(Inverted)
For fixed installations, and for those that want the projector out of sight or have a limited 
space for projector and audience, you can invert the VX-22d and suspend it from the 
ceiling using a specially-designed ceiling mount fixture. 
 
The projector can also be inverted and placed in an enclosure above and behind the 
viewing area. Install four feet on the inside bottom surface of the enclosure on which the 
projector can rest. A variety of materials can be used for this purpose (for example, rubber 
crutch tips or turntable feet). 
Adjusting the Projection 
Angle 
If the VX-22d is ceiling-mounted and the screen is significantly lower than the projector, 
you can tilt the projector at a slight angle by adjusting the ceiling mount. 
If you do this, you may need to shift the image using the on-screen display (OSD) controls, 
to compensate. For detailed instructions, refer to 
Using the On-Screen Menus on 
page 45.
Use only the Runco-approved ceiling mount kit designed for your 
projector. Install the mount kit according to the instructions 
provided with it. Note

Connections to the 
VX-22d and DHD 
Controller 
Proceed as follows to connect the DHD Controller to the VX-22d, your video sources, 
external controller(s) – if present – and AC power.
When connecting your equipment:
 Turn off all equipment before making any connections.
 Use the correct signal cables for each source.
 Ensure that the cables are securely connected. Tighten the thumbscrews on 
connectors that have them.
Connector Panel AccessTo access the connector panel, pull firmly on the cable access cover to open it.
Connecting the DHD 
Controller to the VX-22d
The VX-22d is designed to receive only digital input signals directly from the companion 
DHD Controller/Processor. All signal sources should be connected to the appropriate 
inputs on the rear panel of the controller. The signal from the controller is then output to 
the VX-22d projector through a DVI-DL (dual-link) cable. 
Use a Runco DVI Dual-Link (DVI-DL) cable to connect the output of the DHD Controller to 
the input of the VX-22d; see 
Figure 3-7. 
Figure 3-7. Connecting the VX-22d to the DHD Controller
➤
➤
You CANNOT connect a signal source with DVI output directly to 
the VX-22d. It MUST be routed through the DHD Controller for 
proper operation.Note
