Setting Up the Projector 13
Setting Up the Projector
Follow the instructions in this section to choose a location for the projector, connect the
cables, and display an image.
Choosing a Location
You can install the projector for various viewing setups, as shown below.
Center
Ceiling
Side

14 Setting Up the Projector
Ideally, place the projector at a height where
its lens is between the top and bottom of the
screen. That way, you can keep the projector
level and use the vertical lens shift dial to
position the image. This produces the
best-looking picture.
If you place the projector above or below
screen level, you’ll have to tilt it up or down to
aim the image at the screen; this distorts the
shape of the image, but you can correct its
shape using the projector’s Keystone function
(see page 25).
If you place the projector off to the side, aim it straight ahead (rather than at the center of the
screen), then use the horizontal lens shift dial to center the image on the screen. Do not place
the projector too far to the left or right, or your image won’t be rectangular.
Caution: Do not try to move the lens by hand, or you may damage the projector. Always use the
lens shift dials to change the lens position.
Vertical lens shift dialHorizontal lens shift dial

Setting Up the Projector 15
The maximum size of the image is determined by the distance from the projector’s lens to the
screen. Depending on your display settings and how you use the Zoom ring, the actual size
may be smaller. Use this table as a rough guide for projector placement:
To determine the exact image size when you know the projection distance (or the exact
projection distance when you know the desired image size), you can use the Projection
Distance Calculator. You can download this program from the Epson website at
epson.com/support.
Also keep these considerations in mind:
■Make sure there is plenty of space for ventilation around and under the projector. Do not
set the projector on top of loose materials that could block the vents underneath.
■Make sure the projector is within 9.8 feet of a grounded electrical outlet or extension
cord.

16 Setting Up the Projector
Installing the Projector
To install the projector, you first need to determine the location, based on the size of your
screen (maximum diagonal image size). Use the table on page 15 as a guide to locating the
projector. Note the following dimensions:
■Distance from the center of the lens to the mounting bracket holes: 2.32 inches (59 mm),
0.34 inch (8.6 mm) maximum vertical lens shift
■Distance from the center of the lens to the center of the projector: 4.33 inches (110 mm),
0.30 inch (7.7 mm) maximum horizontal lens shift
The following illustrations show the dimensions of the projector:

Setting Up the Projector 17
You will need the optional projector mount designed for the projector. See page 11 for
ordering information.
Warning: When installing or adjusting the ceiling mount, do not use adhesives to prevent the
screws from loosening and do not use any type of oil or lubricant. These may cause the projector
casing to crack and the projector may fall, causing serious injury and serious damage to the
projector.
Follow the instructions included with the mount to install the projector, which weighs
11.5 pounds. The wall or ceiling where you install it must be capable of supporting a weight
of 58 pounds.
In addition to the tools supplied with the projector mount, you will need a Phillips head
screwdriver and a drill to use on the wall or ceiling.
If you install the projector on the ceiling, you will need to
invert the picture so that it appears right side up. Follow
these steps:
1. Press the Menu button on the remote control.
2. Press the menu navigation buttons to open the
Settings menu, then select Projection.
3. Use the navigation buttons to select Front/Ceiling.
4. Press the Menu button when done.
If you are planning to use an AV controller with the projector,
refer to the table of ESC/VP21 command codes on page 65.

18 Setting Up the Projector
Connecting the Cables
You can connect the projector to any type of video equipment, such as a VCR, DVD player,
digital tuner, cable or satellite box, video game console, camcorder, or digital camera. You can
also connect it to a desktop or laptop PC or Apple®Macintosh®system.
You can connect up to five pieces of video equipment at the same time, using any of the
commercially available cables shown below:
* For details on compatible video formats, see page 63.
Port name Video equipment connection* Computer connection*
HDMI Use an HDMI cable:
Component Use a component video cable (with
RCA-style connectors):
Connect the cable to the three
component video ports. Match
corresponding colors between the
cable and the ports.

Setting Up the Projector 19
For best results, connect your video equipment to the HDMI (High-Definition Multimedia
Interface) port, if possible. If your equipment doesn’t support HDMI, connect it to one of the
following ports (highest quality listed first): Component (for component video), S-Video, or
Video (for composite video).
If you connect to the Component port, be sure to select the correct Input Signal setting for
your equipment, or the image may not display properly (see page 22).
Making Other Connections
Connect the power cable and other cables described below, depending on how you plan to
use the projector.
■Plug the power cable into the projector and a grounded electrical outlet.
Connect video equipment to one
of these ports
Connect a computer to one
of these ports

20 Setting Up the Projector
■The Trigger out port outputs a 12-volt DC signal
when the projector is turned on. This lets a central
control system monitor whether the projector is on
or off, and can be used to raise or lower your
projection screen automatically when the projector
is in use.
Connect a 3.5-mm mini jack to the port, as shown.
Installing Batteries in the Remote Control
The remote control uses 2 AA batteries.
Warning: Keep batteries away from children. If a battery is swallowed, contact your doctor
immediately.
1. Release the tab and lift open the cover.
2. Insert 2 new AA batteries as shown.
3. Insert the tab on the cover and press it down until it
clicks into place.
Aim the remote control at the front or back of the
projector. Make sure you are within 30 feet of the
projector with the remote aimed within a 30° angle from
the infrared receivers.
When you suspect the batteries are weak, take the
remote control to a darkened room and press the illumination button. If the buttons do
not glow red, replace the batteries.
