Installation and Setup
SECTION 2
The instructions provided here are for those that are familiar with the projector and wish 
to  quickly  set  it  up  and  use  it  temporarily.  Refer  to  the  remaining  subsections  of  this 
manual for a more complete setup.
Install the Projection Lens
The projection lens is shipped separately from the projector and must be installed prior to 
setting up the projector. Install the projection lens as described in Section 4.5, 
Replacing 
the Projection Lens.
Remove  the  lens  plug  from  the  lens  opening  in  the  projector  before  installing  the 
lens.
Remove the lens when shipping the projector and  reuse the lens plug to prevent 
dust and debris from entering and settling on critical optical components.
Position the Projector
Place the projector on a sturdy, level surface and position it so that it is perpendicular to 
the screen at a suitable distance. In general, the further back the projector is positioned 
from the screen, the larger the image will be.
If  required,  you  can  level  the  projector  by  adjusting  its  three  feet.  With  the  projector 
positioned  perpendicular  to  the  screen  the  image  will  appear  rectangular  and  not 
keystoned.
For more detailed instructions on positioning the projector, refer to  Projector Position and 
Mounting later in this section.
Connect a Source
Located at the back of the projector is the input panel where all source connections are 
made. Each input is clearly labeled for easy identification. Using the appropriate cable(s), 
connect your source. Connect RGB and YPbPr sources to  INPUT 1 located in the upper 
right corner of the input panel. Use the DVI-I connector at  INPUT 2 to connect analog 
or  digital  display  signals.  INPUTS  3  and  4  (Composite  and  S-Video)  are  available  but 
generally not used since these signals would be input to the included DHD Contr oller.
NOTE: One of the available optional input modules can be installed at INPUT 5 or 
INPUT 6 for additional connections.
Refer to Section 2.3, Connecting Sources, for more details on connecting a specific 
source.

Connect the Power Cord
NOTE: The North American rated power cord is provided with each projector
.
Plug the power cord to the AC receptacle located on the right hand side of the projector 
and the 3-pronged end into a grounded AC outlet. The input voltage to the projector must 
be between 100 and 240 VAC in 1000W models (VX-40d and VX-60d) and between 200 
and 240VAC in 1200W models (VX-50d and VX-80d). Refer to Section 6, 
Specifications, 
for complete details on all power requirements. 
Use the approved North American-rated power cord supplied with the projector. If you are 
connecting to an area outside of North America make sure you are using an appropriately 
rated power cord.
Turn the Projector ON
Press the 
 POWER button on either the remote or built-in keypad to turn the projector 
on,  or  turn  the  power  on  the  DHD  Controller  (after  fully  connecting  it  to  the  projector), 
which will also turn on the projector. Wait a few minutes to allow the projector to warm up. 
The LED status window displays an active pattern of segments to indicate the projector is 
changing its state from powered down to powered up. The message “On” appears in the 
display when the projector has completed its initialization and is ready for use.
Select a Source
Press  one  of  the  input  keys  on  the  remote  or  built-in  keypad  to  select  and  display  the 
image for the source. With the DHD Controller, this would be either RGB (Input 1) or DVI 
(Input 2).
Adjust Image
To perform an “Auto-setup,” press 
FUNCS, then AUTO followed by Enter to initiate an 
automated  process  in  which  the  projector  optimizes  critical  display  parameters  such  as 
size,  position,  pixel  tracking  etc.  for  the  selected  source.  Press  Enter  again  to  keep  the 
new settings. 
NOTE: You can also access the menu system and adjust these and other image settings 
by pressing MENU on the remote.

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.
Choose the installation type that best suits your needs: front or rear screen, floor mount 
or inverted mount.
Front Screen, Floor Mount Installation
AdvantagesConsiderations
• Easy to set up
• Can be moved or changed quickly
• Easy to access
• Shares floor space with audience
Front Screen, Inverted Mount (ceiling) Installation
AdvantagesConsiderations
• Does not take up audience space
• Projector is unobtrusive
•  Projector cannot be accidentally moved• Installation is more permanent
•  It is more difficult to access the projector
Rear Screen, Floor Mount Installation
AdvantagesConsiderations
• Projector is completely hidden
• Projector is easily accessed
• Usually good ambient light rejection • Requires separate room
• Installation cost is usually higher
Rear Screen, Inverted Mount (ceiling) Installation
AdvantagesConsiderations
• Projector is completely hidden
• Usually good ambient light rejection • Requires separate room• Installation cost is usually higher
Rear Screen, Floor Mount with Mirror
AdvantagesConsiderations
• Projector is completely hidden
• Usually good ambient light rejection
•  Requires less space behind screen than other  rear screen installations • Requires separate room• Installation cost is usually higher
Front Screen Installations
In front-screen installations, the projector and audience are positioned in front of the 
screen, which can be flat or curved.
Flat screens are recommended with this projector. They offer a gain of about 1 with 
a viewing angle just less than 180°. This type of screen reflects incident light equally 
in all directions so the audience can see the display from various angles.
Curved screens have a gain greater than 1 with a viewing angle much less than 180°. 
This type of screen does not reflect incident light equally in all directions; instead, 
it is concentrated in a viewing cone. The audience sitting within the viewing cone 
area sees a brighter image than those sitting just outside this area. Runco generally 
does not recommend use of curved screens with the Video Xtreme series, due to 
excessive brightness and uncorrectable geometrical distortion.

Section 2: Installation and Setup

Rear screen installations
There are two basic types of rear screens: diffused and optical.
A diffusion screen has a surface which 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.  This  type  of  screen  is 
suitable when a wide viewing angle is required but there is low ambient room lighting.
Optical screens take light from the projector and redirect it to increase the light intensity at 
the front of the screen. This reduces it in other areas. A viewing cone similar to that of a 
curved, front-screen installation is created. This type of screen is better suited for brightly 
lit rooms where the audience is situated within the viewing cone.
Screen size
Choose  a  screen  size  that  is  appropriate  for  your  lens  and  application.  The  size  of  the 
room  and  viewing  distance  are  the  defining  factors;  a  rule  of  thumb  is  that  the  primary 
viewing distance be 1.5 times the screen width.
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).

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.
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, 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, elevators, etc.
Throw distance
Throw distance is the distance measured from the projector’s lens 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  width  of  the  screen  and 
multiplying  it  by  the  lens  throw  ratio.  See  Figure  2.1.  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. For example, using a 0.75:1 lens, 
throw distance would roughly be 0.75 x screen width.

Vertical and horizontal position
The correct vertical and horizontal position of the projector in relation to the screen 
depends on the lens type and the screen size. Ideally, the projector should be positioned 
perpendicular to the screen. This way, the image will appear rectangular instead of 
keystoned (trapezoidal).
The 
vertical position  of the image can be offset – that is, moved above or below 
the optical axis (lens center) – by adjusting the fully motorized lens mount using the 
keypad. The amount of vertical offset available depends directly on the lens installed 
in the projector and can be slightly limited if horizontal offset has been applied.
Vertical offset can also be expressed as the percent of half the image height OR the 
number of pixels of shift from lens center. See Figure 2.2 for some illustrated examples 
of vertical offset.

The 
horizontal position of the image can be offset – that is, moved to the left or right of 
lens center – by adjusting the fully motorized lens mount. The amount of horizontal offset 
available depends on the lens installed and if the image has already been vertically offset. 
Horizontal  offset  can  also  be  expressed  as  the  percent  of  half  the  image  width  –  the 
number  of  pixels  of  shift  to  one  side  of  lens  center.  See  Figure  2.4  for  some  illustrated 
examples of horizontal offset.
Also refer to Tables 2.1, Table 2.2 and Figure 2.5, which shows the maximum horizontal 
offset of a lens or alternatively, how much of your projected image will appear to one side 
of lens center if the maximum horizontal offset is applied using that lens.
