Setting Up the Projector
This chapter tells you how to set up the projector and connect it to a
computer or video source. You can connect up to four devices
simultaneously: four video sources, one computer and three video
sources, or two computers and two video sources.
You’ll find instructions for the following in this chapter:
â– Positioning the projector
â– Connecting to a computer
â– Connecting to video sources
14 Setting Up the Projector
Positioning the Projector
Before connecting the projector, you
need to decide where to place it. If
you’re setting up the projector yourself
and it isn’t already installed in the
room you’re using, you’ll probably
want to place it on a table in front of
the screen, as shown.
This lets you stand in the front of the room, face the audience, and
remain close enough to the equipment to be able to control it. Try to
leave as much space as possible between the projector and the screen to
get a good-size image.
Place the projector somewhere between 3 and 48 feet from the screen.
Use the figure below to help you determine exactly how far. Image size
increases with distance, but can vary depending on how you’ve
adjusted the optical zoom and other settings.
Also keep these considerations in mind:
â– Place the projector on a sturdy, level surface.
â– Make sure there is plenty of space for ventilation around and
under the projector. Do not set the projector on top of loose
papers that could block the vents under the projector.
â– Make sure the projector is within 6 feet of a grounded electrical
outlet or extension cord.

note
You can download the
Projection Distance
Calculator program from
the Drivers & Downloads
link for your projector at
http://support.epson.com.
Setting Up the Projector 15
Try to place the projector directly in front of the center of the screen,
facing the screen squarely. If the projector isn’t positioned this way,
the image will be “keystone” shaped, instead of square or rectangular.
If you place the projector below the level of the screen, you’ll have to
tilt it up by extending the front adjustable foot, as described on
page 37. This also causes the image to lose its rectangular shape, but
the Auto Keystone feature corrects the distortion automatically. If the
image does not regain its rectangular shape, the tilt angle is greater
than 15° or the Auto Keystone feature may have been disabled. To
turn it on, see page 58. To adjust it manually, see page 38.
Other Installations
You can also project from behind the screen or from the ceiling, with
the projector mounted upside-down:
To project from overhead, you’ll need the optional ceiling mount
hardware. (See page 12 for ordering information.) You’ll also need to
select Front/Ceiling or Rear/Ceiling for the Projection option in the
Extended menu. To project from the rear, select Rear. See page 59 for
more information.
note
The Auto Keystone feature
corrects vertical distortion
automatically. For more
information, see page 38.

16 Setting Up the Projector
Connecting to a Computer
You can connect the PowerLite projector to any computer that has a
standard VGA or BNC monitor port, including PC notebook
computers, Macintosh PowerBooks and iBooks, and hand-held
devices. You can connect two computers at the same time.
Follow the instructions in this section to:
â– Connect the projector to your computer with the VGA cable
included with the projector.
â– Connect the projector to your computer with a
commercially-available VGA–5BNC cable.
After connecting the projector to your computer, you may also
want to:
â– Connect the USB cable that came with your projector so that you
can use the remote control as a wireless mouse; see page 19.
â– Connect a monitor to the projector so you can view your
presentation close-up as well as on-screen (not necessary if you’re
using a notebook); see page 20.
â– Connect a commercially-available computer audio cable to play
computer audio; see page 21.
Connecting with the VGA Cable
Follow these instructions to connect to your computer with the VGA
cable that came with your projector. Before you start, make sure your
computer and the projector are turned off.
1. If you are connecting the projector to a desktop computer,
disconnect the monitor cable from your computer.
2. Locate the VGA computer cable that
came with the projector.
note
If you have an iBook with
an RCA video-out port,
follow the instructions for
connecting to a video device
on page 23.
note
You cannot connect your
computer to the projector
using only a USB cable. To
receive signals from the
computer, you must connect
it with the VGA cable that
came with your projector or a
VGA–5BNC cable.
Connecting the USB cable
lets you use the remote control
as a wireless mouse.

3. Connect one end of the cable to the projector’s
Computer1/Component Video1 or the
Computer2/Component Video2 port. If you are going to
connect your computer monitor to the projector for simultaneous
display, use the Computer1/Component Video1 port.
4. Connect the other end of the cable to your computer’s video-out
or monitor port.
If you’re using a PowerBook or iBook and you can’t connect the
cable, you may need to use the Macintosh desktop adapter as
shown below (available from Epson; see page 12).
To use the adapter, remove its cover as
shown and set its DIP switches according
to the resolution you want to use, such as
16-inch mode. See your Macintosh
documentation for instructions.
Replace the cover and connect the
adapter to the free end of the computer
video cable. Then plug the cable (with
the adapter) into the video port on your
Macintosh.
5. Tighten the screws on the connectors.
If you want to view the display simultaneously on your computer
monitor and the projector screen, see “Connecting an External
Monitor” on page 20.
18 Setting Up the Projector
If you don’t need to make any other connections, you can plug in
your projector and turn it on. See page 30 for instructions.
If more than one device is connected to the projector, select the
correct source after projection starts by pressing the Source Search
button on the projector or the Comp1 Comp2 or button on the
remote control. See page 32.
Connecting with a VGA-5BNC Cable
If your computer provides video output through BNC connectors,
follow these instructions to connect the projector to your computer
with an optional VGA-5BNC cable. Before you start, make sure your
computer and the projector are turned off.
1. Disconnect the monitor cable from your computer.
2. Connect the cable’s VGA connector to the projector’s
Computer1/Component Video1 or the
Computer2/Component Video2 port. If you are going to
connect your computer monitor to the projector for simultaneous
display, use the Computer1/Component Video1 port.
3. Connect the BNC connectors to your computer’s BNC ports.
4. Tighten the screws on the VGA connector.
If you want to view the display simultaneously on your computer
monitor and the projector screen, see “Connecting an External
Monitor” on page 20.

Setting Up the Projector 19
If you don’t need to make any other connections, you can plug in
your projector and turn it on. See page 30 for instructions.
If more than one device is connected to the projector, select the
correct source after projection starts by pressing the Source Search
button on the projector or the Comp1 Comp2 or button on the
remote control. See page 32.
Connecting the USB Cable for Remote Mouse
Control
Using the remote control as a wireless mouse lets you click through
slideshow-style presentations, such as PowerPoint, from up to 20 feet
away. This makes it easy to deliver your presentation, since you won’t
need to stand near your computer.
To use the wireless mouse function, your system must have a USB
port and the full version of one of these operating systems:
1. If you are using a desktop computer, disconnect the mouse cable
from your computer.
2. Locate the USB mouse cable that came with the projector and
connect the square end of the cable to the projector’s USB
