Connecting to the Computer Port
Follow these instructions:
1. You can connect to the 
Computer port in the following 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 the optional BNC/VGA component video cable, if 
your computer provides video output through BNC 
connectors (see page 14). 
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.

							52Connecting to Computers, Cameras, and Other Equipment 3. 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.
4. Optionally, you can connect an external monitor (see page 57), 
play sound through the projector (see page 65), or connect a USB 
cable to use the remote control as a mouse (see page 56).
5. When you’ve finished making any connections, see Chapter 1 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 make sure 
Computer Input is set to 
Analog-RGB. See page 137.
■After exiting the menu system, press the remote control’s 
Comp1 button, or repeatedly press the Computer/DVI 
button on the projector’s control panel to select the correct 
source. 
Computer (Analog-RGB) should appear on the 
screen.

Connecting to the BNC Connectors
1. Obtain a commercially available standard BNC cable. 
2. Plug the BNC connectors into the projector’s 
B/Cb/Pb, G/Y, and 
R/Cr/Pr connectors as shown below. Depending on your 
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 57), 
play sound through the projector (see page 65), or connect a USB 
cable to use the remote control as a mouse (see page 56).
5. When you’ve finished making all necessary connections, see 
Chapter 1 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 make sure the BNC 
Input is set to 
Analog-RGB. See page 137.
■After exiting the menu system, press the BNC button on 
the remote control or repeatedly press the 
Video/BNC button 
on the projector’s control panel to select the correct source.

Connecting to the DVI Port
1. Obtain a DVI digital video cable (either DVI to DVI or DVI to 
DFP; see page 14 for details about ordering a cable from 
EPSON).
2. Connect the cable to the projector’s 
DVI port as shown. 
 
3. Connect the other end to your computer’s DVI port.
4. Optionally, you can connect an external monitor (see page 57),

cable to use the remote control as a mouse (see page 56).
5. When you’ve finished making any connections, see Chapter 1 for 
instructions on turning on the projector and adjusting the image. 
Once the projector is turned on, press the 
DVI button on the 
remote control, or press the 
Computer/DVI button on the 
projector’s control panel to select 
DVI as the image source. 
note
Various types of DVI cables 
are offered on the market. 
Be sure to use only a cable 
with DVI to DVI or DVI to 
DFP connectors.

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 13). 
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.

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. In the projector’s menu system, set the 
COM Port setting in the 
Advanced 2 menu to 
USB. See the instructions beginning on 
page 124 to use the menu system.
5. 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 
page 44.

Connecting an External Monitor
If you want to monitor your presentation close-up (on a monitor 
placed beside the projector) as well as on the screen, you can connect 
an external monitor. 
To attach an external monitor, connect it to the projector’s 
Monitor

 port, as shown:
 
Follow these guidelines to view images on the monitor:
■The monitor displays the currently selected computer source. 
Press the 
Preview button on the remote control if you want to 
display all the active sources at the same time (see page 36).
■You can also view images on the monitor while the projector is in 
Standby mode, if you’ve set 
Network ON in the Advanced 1 
menu (see page 138).

Connecting to Video Equipment 
You can connect up to four video sources to the projector at the same 
time. Before starting, look at your video equipment to determine its 
available video-output connections: 
■If your video player has a yellow RCA-style video output 
connector, see “Connecting a Composite Video Source” on 
page 59.
■If your video player has an S-video connector, see “Connecting an 
S-Video Source” on page 60.
■If your video player has a component video port (three connectors 
labeled either Y/Cb/Cr or Y/Pb/Pr), see “Connecting a 
Component Video Source” on page 61.
■If your video player has an RGB video port (either a single 
connector for a VGA-style monitor cable, or three connectors 
labeled R/G/B), see “Connecting an RGB Video Source” on 
page 62.
After connecting any video cables, you may also want to:
■connect a monitor to the projector so you can view your 
presentation close-up as well as on-screen; see page 57
■connect an audio cable to play sound through the projector; see 
page 65
