Additional Components
Depending on how you plan to use the projector, you may need 
additional components:
■To receive an S-Video signal, you need an S-Video cable. One is 
usually provided with your video device or you can purchase it 
from Epson. See page 13.
■To receive a component video signal from a VCR or other video 
device, you need a D-sub, 15-pin, component-to-VGA video 
cable, which is available from Epson. See page 13.
■Some older PowerBooks and Macintosh desktop models may 
need a Macintosh video adapter; see your computer dealer. Older 
iMac systems may need a special adapter to provide a VGA output 
port; see your computer dealer.
■To receive an audio signal, you need a commercially available 
audio cable; see your computer or electronics dealer.

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, or two computer and two video 
sources. 
You’ll find instructions for the following in this chapter:
■Positioning the projector
■Connecting to a computer
■Connecting to video sources 
						

							16Setting 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 30 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: 
■Place the projector on a sturdy, level surface.
■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. 
■Make sure the projector is within 6 feet (2 meters) of a grounded 
electrical outlet or extension cord.

							Setting Up the Projector17
Try to place the projector directly in front of the center of the screen, 
facing it toward 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 39. This also causes the image to lose its rectangular shape. You 
can adjust the shape using the buttons on the projector (see page 40), 
or using the projector’s menu system (see page 49). 
The Auto Keystone feature corrects the distortion automatically. See 
page 57 for more information about Auto Keystone correction. If 
necessary, you can adjust the image shape manually as described on 
page 40. 
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 13 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 58 for 
more information.

							18Setting Up the Projector
Connecting to a Computer
You can connect the projector to any computer that has a standard 
VGA or BNC monitor port, including PC notebook and laptop 
computers, Macintosh PowerBooks and iBooks, and hand-held 
devices. 
Follow the instructions in this section to:
■Connect the projector to your computer with the VGA cable 
included with the projector.
■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:
■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 laptop); see page 21
■Connect the projector to your computer with a commercially 
available audio cable to play computer audio; see page 22.
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 25.

							Setting Up the Projector19
Connect one end of the cable to the projector’s Computer1 or 
Computer2 port.
3. 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 an optional Macintosh video adapter; 
see your computer dealer.
4. If you connected the computer to the 
Computer1 port and you 
want to view the display simultaneously on your computer 
monitor and the projector screen, see “Connecting an External 
Monitor” on page 21.
5. To play audio from your computer through the projector 
speakers, see “Playing Sound Through the Projector” on page 22.
6. Tighten the screws on the connectors.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 34 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 remote control. See page 36.
