Appendix A: Projector 
Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
Placement and Mounting Guidelines
The projector can be installed for four different viewing setups: front 
projection, ceiling mounting, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need the optional ceiling mounting 
hardware; see page 12 for ordering information. You’ll also need to 
select 
Ceiling in the projector’s Advanced1 menu to flip the image 
upside-down. To project from the rear, select 
Rear Proj (see page 72).
If the projector is positioned at screen-height (anywhere between the 
bottom and the top of the screen), you can use the 
Len Shift function 
to adjust the position of the image on-screen (see page 39). Using the 
Front projection

Rear projectionRear/ceiling projection
note
See page 14 for more 
information on projector 
placement. 
						

							112Appendix A: Projector Installation
Lens Shift is better than angling the projector up or down to position 
the image, since it won’t produce keystone distortion, which must be 
eliminated electronically. 
If you mount the projector on the ceiling above screen level, you’ll 
have to tilt it down to center the image on the screen. This causes the 
image to lose its square shape, but you can correct the distortion by 
using the 
Keystone function in the projector’s menu system (see 
page 67) or by pressing the 
Keystone button on the projector’s 
control panel. 
Image Size and Projection Distance
For standard lens usage, refer to the table below to help you determine 
projector placement if you know the size of image you want to display. 
(For information about using other lenses, see page 113.)
* The projector’s native aspect ratio is 4:3. When you display a 16:9-sized image, the image height is 
reduced. See page 115.
** Projection distance refers to the horizontal distance from the lens to the screen. The image size will 
differ if you tilt the projector up or down at the screen or use the projector’s Keystone function.
note
If you’ve installed the 
wide-angle rear projection 
lens, you won’t be able to use 
the projector’s Focus, Zoom, 
or Lens Shift functions. You 
must position the projector 
itself to obtain the desired 
image height, size, and focus 
(but Keystone correction can 
still be used).

Image Size Calculations (For All Lenses)
Use the formulas in this section to estimate the required screen size 
and placement of the projector, depending on the type of lens with 
which your projector is equipped. For all lenses except Rear Projection 
Wide, the image size can be adjusted with the Zoom function, as 
indicated by the minimum and maximum calculations.
Standard Lens (V12H004S02)
Image size: 22 to 600 inches (0.56 to 15.24 m)
Projection distance (focal range): 41 to 1218 inches (1.04 to 30.94 m)
■To find the image size when you know the projection distance:
Maximum diagonal size = (0.6709 × projection distance) + 2.6
Minimum diagonal size = (0.4908 × projection distance) + 1.8
■To find the projection distance when you know the image size:
Maximum projection distance = (2.037 × diagonal size) – 3.8
Minimum projection distance = (1.490 × diagonal size) – 3.8
Rear Projection Wide Lens (V12H004R02)
Image size: 55 to 120 inches (1.40 to 3.05 m)
Projection distance (focal range): 37 to 84 inches (0.94 to 2.13 m)
■To find the image size when you know the projection distance:
Diagonal size = (1.399 × projection distance) + 3.6
■To find the projection distance when you know the image size:
Projection distance = (0.7148 × diagonal size) – 2.6
Wide Zoom Lens (V12H004W02)
Image size: 40 to 600 inches (1.02 to 15.24 m)
Projection distance (focal range): 40 to 896 inches (1.02 to 22.76 m)
■To find the image size when you know the projection distance:
Maximum diagonal size = (0.9454 × projection distance) + 2.5
Minimum diagonal size = (0.6671 × projection distance) + 1.7
■To find the projection distance when you know the image size:
Maximum projection distance = (1.4990 × diagonal size) – 2.5
Minimum projection distance = (1.0578 × diagonal size) – 2.7
note
All variables are in inches. 
The image size refers to the 
diagonal dimension of a 4:3 
image. If you need to 
determine the diagonal of an 
image from its width or 
height, or work with 
16:9-sized images, see 
page 115.

							Appendix A: Projector Installation115
Converting Between Diagonal Size and Width 
or Height
The calculations on the previous pages use the diagonal length of an 
image to indicate its size. 
■Use these formulas if you want to find out the diagonal size of a 
4:3 image from its width or height:
Diagonal size = 5/4 × width
Diagonal size = 5/3 × height
■Use these formulas if you want to find out the width or height of 
a 4:3 image from its diagonal size:
Width = 4/5 × diagonal size
Height = 3/5 × diagonal size
Converting Between 16:9 and 4:3 Image Sizes
The image size calculations on on the previous pages assume that 
you’re projecting a 4:3-sized image. If you want to project a 16:9 
(widescreen) image, you’ll first need to determine the corresponding 
size of a 4:3 image before using the calculations.
Since the projector’s native aspect ratio is 4:3, the image height is 
reduced when you project a 16:9 image:
If you know the height of the 16:9 image you want to project, 
multiply it by 20/9 to determine the diagonal of the corresponding 
4:3 image. Then use the image size calculations to determine the 
projection distance. 
If you’ve already used the projection distance to calculate the diagonal 
of a 4:3 image, multiply it by 9/20 to determine the height of the 
corresponding 16:9 image.
16:9 image
4:3 image
16:9 image is 75% as high as 4:3 image

Installing the Rear Cable Cover
If you’re mounting the projector 
on the ceiling, install the rear 
cable cover to enhance the 
appearance of the system. To 
install the cover, insert its tabs 
into the slots as shown, then 
push the cover against the 
projector until it locks into place.
To remove the cover (when 
replacing the lamp and 
connecting or disconnecting 
cables), release the locking tab on 
the bottom of the cover as shown:
Installing Multiple Projectors
If multiple projectors are installed in one room, you can assign to each 
projector a separate ID number. This lets the presenter use the remote 
control to operate each projector independently (see page 48). 
If you have multiple projectors installed at your place of business and 
want to be able to monitor and control them over a network, see 
“Managing the Projector from a Remote Computer” on page 73.
To open, 
release the 
locking tab
note
A remote control cable set 
is available that lets you 
operate the projector from 
extended distances (see 
page 12).
