Unpacking the Projector
After unpacking the projector, make sure you have all these parts: 
Save all packaging in case you need to ship the projector. Always use 
the original packaging (or the equivalent) when you need to send the 
projector to another location. See page 65 for transportation 
instructions. If you are moving the projector by hand, consider using 
an optional carrying case, available as an accessory from Epson (see 
page 11.)

Additional Components
Depending on how you plan to use the projector, you may need 
additional components:
■To receive a video signal from a computer with a USB port, you’ll 
need a USB cable. One may be provided with your computer, or 
you can purchase one from Epson. See “Optional Accessories” on 
page 11.
■To receive a component video signal from a DVD player or other 
video device, you’ll need a component-to-VGA video cable. One 
may be provided with your video equipment, or you can purchase 
one from Epson. See “Optional Accessories” on page 11.
■To receive an S-Video signal, you’ll need an S-Video cable. One 
may be included with your video equipment, or you can purchase 
one from Epson. See “Optional Accessories” on page 11.
■To receive an audio signal, you’ll need an RCA-type audio cable 
with two male plugs, or a stereo mini-jack audio adapter cable.
Positioning the Projector
If the projector 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. 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.
Keep these considerations in mind as you position the projector:
■Place the projector on a sturdy, level surface.
■Make sure there is plenty of space for ventilation around and 
under the projector.
■Make sure the projector is within 5.9 feet (1.8 meters) of a 
grounded electrical outlet or extension cord.

Projector Placement Options
When projecting from the front, you should place the projector 
directly in front of the center of the screen, facing the screen squarely. 
The center of the lens should be about level with the bottom of the 
screen.

note

connect a Kensington 
MicroSaver
® anti-theft 
device to the lock port on the 
projector. You can purchase 
this from Epson; see 
page 11.
Front projection 
						

							18Setting Up the ProjectorIf you place the projector below screen level, you may need to tilt it up 
by extending the front adjustable foot. Tilting the projector causes the 
image to become “keystone” shaped, but you can correct the 
distortion (see page 33).
You can also install the projector in three other viewing setups: ceiling 
projection, rear projection onto a semi-transparent screen, or 
rear/ceiling projection.
To project from overhead, you’ll need the optional ceiling mounting 
hardware (see page 11). You’ll also need to select the appropriate 
Projection setting in the projector’s Extended menu to orient the 
image correctly (see page 50).
Connecting to a Computer
You can connect the projector to a Windows® computer using the 
projector’s 
TypeB USB port. This lets you carry a lightweight cable 
with you when you transport the projector.
You can also connect the projector to any computer that has a 
standard video output (monitor) port, including desktop models, 
PC notebook computers, Macintosh PowerBook
® and iBook® 
computers, and hand-held devices. See page 20 for instructions.
To play sound through the projector, connect an audio cable (see 
page 26).
You may be able to use your remote control as a wireless mouse when 
projecting from a computer (see page 41).

Connecting to the USB Port
You can connect a Windows Vista, XP, or Windows 2000 (SP4) 
computer to the projector’s 
TypeB (square)  USB port and 
project your computer’s display. A USB 2.0 connection 
(recommended) provides better picture quality and response than 
USB 1.1.
The first time you connect a computer to the projector’s USB port, 
software from the projector is installed on your computer. 
1. Follow the instructions beginning on page 26 to turn on the 
projector.
2. Make sure the 
USB Type B setting on the Extended menu is set 
to 
USB Display (see page 50).
3. Turn on your computer.
4. Connect the square end of a USB cable to the projector’s 
TypeB 
(square) USB port.
5. Connect the flat end of the cable to any available USB port on 
your notebook or desktop computer.
Messages appear on your computer screen as the projector is 
recognized and the software is installed automatically.
6. Follow the instructions on the screen to install the Epson USB 
Display software. If you see a “Digital Signature Warning,” select 
Continue or Continue Anyway. (You will see these instructions 
only the first time you connect.)

							20Setting Up the ProjectorAfter the software is installed, you see your computer’s current 
desktop displayed by the projector. You can switch the projector 
to other image sources using the 
Source Search button on the 
remote control or the projector.
7. You can connect an optional audio cable if you want to play 
sound through the projector (see page 26). 
When you’ve finished making connections, see Chapter 2 for 
instructions on displaying and adjusting the image.
When you’re done projecting from your computer, disconnect the 
USB cable.
Connecting to the VGA Computer Port
You can connect to the projector using the VGA computer cable that 
came with it (the monitor port on your computer must be a D-sub 
15-pin port). 
1. Connect one end of the VGA computer cable to the projector’s 
Computer (Component Video) port and the other end to your 
computer’s monitor port.
 
2. You may need to change the Input Signal setting in the 
projector’s Signal menu to 
RGB(see page 48).
3. You can connect an optional audio cable to play sound through 
the projector (see page 26). 
4. You may also be able to use the remote control as a wireless mouse 
(see page 40).
caution
Don’t try to force a 
connector to fit a port with a 
different shape or number of 
pins. You may damage the 
port or connector.
