Connecting a Component Video Source
1. Locate a component video cable (one may be included with your 
video equipment). 
Look at the connectors at one end of the cable. If they are 
bayonet-style (BNC) connectors, continue on to the next step. If 
they are RCA-style connectors, you’ll need to attach commercially 
available BNC adapters to plug the cable into your projector.  
2. Connect the cable (with the adapters) to your player and the 
BNC 
connectors on the projector. Match the Y/Cb/Cr (or Y/Pb/Pr) 
connectors on your player to the corresponding connectors on the 
projector.
3. If you want to play sound through the projector, see page 24 for 
instructions on connecting an audio cable.
4. If you don’t need to make any other connections, see Chapter 2 
for instructions on turning on the projector and adjusting the 
image. Once the projector is turned on, do the following:
■Enter the projector’s Setting menu, then change the BNC 
Input setting to 
YCbCr or YPbPr, as needed (see page 72).
■After exiting the menu system, press the remote control’s 
BNC button or repeatedly press the projector’s Video/BNC 
button to select 
BNC as the image source.

note
Be sure your video player is 
not an RGB video source. If 
you set the wrong source, 
image quality may suffer. 
Check your video player’s 
documentation.

Connecting an RGB Video Source
Follow these instructions to connect the projector to a video player 
that has an RGB video output port. Depending on the type of 
connector on your player, you’ll need to use the appropriate cable:
■If your player has a single VGA-style connector, see below.
■If your player has three connectors labeled R/G/B, see 
“Connecting Using a BNC-style Cable” on page 15.
Connecting Using a VGA-style Computer Cable
1. Locate the VGA computer cable provided with the projector. 
2. Connect the cable between the video port on your player and the 
Computer port on the projector.
3. If you want to play sound through the projector, see page 24 for 
instructions on connecting an audio cable.
4. If you don’t need to make any other connections, see Chapter 2 
for instructions on turning on the projector and adjusting the 
image. Once the projector is turned on, be sure to:
■Enter the projector’s Setting menu, then change the 
Computer Input setting to 
RGB-Video (see page 72).
■After exiting the menu system, press the remote control’s 
Comp button or the projector’s Computer/DVI button 
repeatedly to select the image source. (

Connecting to a Computer 
You can connect the PowerLite projector to any computer that has a 
standard video output (monitor) port, including desktop models, 
PC notebook and laptop computers, Macintosh PowerBooks and 
iBooks, and hand-held devices. You can connect up to three 
computers at the same time:
■To connect to the Computer port (standard VGA cable 
connection), see page 17.
■To connect using the BNC ports, see page 19.
■To connect using the DVI (Digital Video Interface) port, see 
page 20.
After connecting to the computer, you may also want to:
■connect a USB cable so you can use the remote control as a 
mouse; see page 22
■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 23
■connect an audio cable to play computer audio; see page 24 
note
If you connect a Windows-
based computer to the 
projector, you may see a 
New Hardware Wizard 
saying your computer has 
found a plug-and-play 
monitor; if so, click Cancel. 
						

							Setting Up the Projector17
Connecting to the Computer Port
Follow these instructions:
1. You can connect to the 
Computer port in three ways:
■using the VGA computer cable that came with the projector 
(the monitor port on your computer must be a mini D-sub 
15-pin port)
■using a commercially available 13w3 D-sub 15-pin cable, if 
your computer has a 13w3 monitor port
■using the optional BNC/VGA component video cable, if 
your computer provides video output through BNC 
connectors (see “Optional Accessories” on page 6). 
2. If you’re using the VGA computer cable, connect one end to the 
projector’s 
Computer port, and the other end to your computer’s 
monitor port. Then go to step 4.
 
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.

note
If you’re using a PowerBook 
or an older Macintosh and 
you can’t connect the cable 
to your computer, you may 
need to use the Macintosh 
desktop adapter as shown on 
page 21 (available from 
EPSON; see page 6). 
						

							18Setting Up the Projector3. If you’re using the optional BNC/VGA cable, connect the VGA 
connector to the projector’s 
Computer port and plug the BNC 
connectors into your computer’s monitor ports.

computer’s video card, you may have to connect to the projector’s 
V Sync and H/C Sync connectors too. (See your computer 
documentation for more information.)
3. Plug the connectors on the other end of the cable into the BNC 
video out connectors on your computer.
4. Optionally, you can connect an external monitor (see page 23),

Using the Macintosh Desktop Adapter
If you have an older desktop Macintosh or PowerBook, the VGA 
cable may not fit when you try to connect it. If so, you’ll need to use 
the Macintosh desktop adapter to connect the VGA cable to your 
computer. This is available from EPSON (see page 6). 
1. 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.
2. Replace the cover and connect the adapter 
to the VGA cable. Then plug the cable 
(with the adapter) into the video port on 
your Macintosh.
3. Tighten the screws on the connectors. 
						

							22Setting Up the Projector
Connecting the Cable for Remote Mouse 
Control 
If you’ve connected a computer as described in this chapter, you 
can use the projector’s remote control as a wireless mouse. This lets 
you control your computer and click through slideshow-style 
presentations, such as PowerPoint, from up to 30 feet away. 
The wireless mouse function is supported on systems with a USB port 
running Windows XP, 98, 2000, or Me, or Macintosh OS 8.6 to 
OS X 10.2. 
1. Locate the USB cable that came with your projector. 
2. Connect the square end of the cable to the projector’s   USB 
port. 
3. Connect the flat end of the cable to any available USB port on 
your laptop or desktop computer.
4. If necessary, configure your computer to work with an external 
USB mouse. See your computer documentation for details.
note
For details on using the 
remote control in place of 
your computer’s mouse, see
