Connecting to a Computer
Caution :
When connecting the projector to a computer, be sure to check the following.
 Turn off the power for both the projector and the computer before connecting them. If 
the power for either device is on at the time of connection, damage may result.
 Check the shapes of the cable connectors and the device ports before making the 
connections. If you try to force a connector to fit a device port with a different shape or 
number of terminals, damage to the connector or port may result.
Eligible Computers
The projector cannot be connected to some types of computer, or projection of 
images may not be possible even if actual connection is possible. Make sure 
that the computer you intend to use satisfies the conditions given below.
Condition 1: The computer must have a video signal output port.
Check that the computer has a port such as an RGB port, monitor port or CRT 
port which can output image signals. 
If the computer has a built-in monitor, or if using a laptop computer, it may 
not be possible to connect the computer to the projector, or alternatively you 
may need to purchase a separate external output port. Refer to the 
documentation for your computer under a heading such as Connecting an 
external monitor or similar for further details.
Condition 2: The display resolution and frequency of the computer must be 
listed in the List of Supported Monitor Displays.
See “Appendix: List of Supported Monitor Displays”(P.106)
Some computers may have functions for changing the output resolution. For 
details, refer to the section of the documentation provided with your computer 
and change the setting to within a range given in the list of supported 
resolutions.

Projecting Images from the Computer
The shape and specifications of the computer’s monitor port will determine 
which projector port and what type of cable should be used. Check the 
following to see which type of port your computer has.
Use the accessory computer cable to connect the Computer 2/Component Video 
port at the rear of the projector to the monitor port of the computer.
If you are connecting two computers with analog RGB output to the projector, 
use the optional DVI analog cable to connect the monitors of the two computers 
to the Computer 1 port at the rear of the projector.
See “Appendix: Optional Accessories” (P.100)
When connecting to the Computer 2/Component Video port
Tip :
 After making the connections, change the Comp2/YCbCr Input setting in the Setting 
menu to Analog-RGB. (P.69)
 Do not bind the power cord and the computer cable together, otherwise image 
interference or errors in operation may result.
 You may need to purchase a separate adapter to connect the computer to the projector, 
depending on the shape of the computers monitor port. Refer to the documentation for 
the computer for details.
 A commercially-available adapter is required in order to connect the projector to a 
Macintosh computer. 
 If the computer and projector are too far away from each other for the accessory cable 
to reach, or if you would like to project computer images at UXGA resolution, use the 
optional computer cable. See “Appendix: Optional Accessories” (P.100)

If the computer has a standard DVI or DFP-compliant digital video card or 
video output port, use an optional digital video cable or DVI analog cable to 
connect the monitor port of the computer to the Computer 1 port at the rear of 
the projector. The type of connection cable used will vary depending on the 
specifications for the computers monitor port.
See “Appendix: Optional Accessories” (P.100)
Tip :
 You may need to change the computer settings when switching the computer output to 
digital RGB. Refer to the documentation for the computer for details.
 If you are connecting a computer with a mini D-Sub 15-pin output port to the projector 
at the same time, connect the computer with the mini D-Sub 15-pin output port to the 
Computer 2/Component Video port of the projector.
 After making the connections, change the Comp1 Input setting in the Setting menu to 
Digital-RGB. (P.69)

Some workstation-type computers have a 13w3 monitor port.
Use a commercially-available 13w3 ⇔ D-Sub 15-pin adapter cable to connect 
the Computer 2/Component Video port at the rear of the projector to the 
monitor port of the computer.
Tip :
 After making the connections, change the Comp2/YCbCr Input setting in the Setting 
menu to Analog-RGB. (P.69)
 Do not bind the power cord and the computer cable together, otherwise image 
interference or errors in operation may result.
 Some workstations may require a special cable. Consult the workstation manufacturer 
for further details.

Playing Sound from the Computer
The projector has a single built-in speaker with a maximum output of 5W. You 
can use this built-in speaker to output the audio signals from a computer by 
using any one of the following three connection methods, depending on the 
shape of the computers audio output port and the type of cable you have.
 By using the accessory A/V cable (white/red) to connect the computers audio 
output ports to the Audio 2 port (RCA jack) at the rear of the projector
 By using a commercially-available audio cable to connect the computers 
audio output ports to the Audio 1 port (stereo mini jack) at the rear of the 
projector. It is recommended that you use an audio cable with a 3.5 mm 
diameter stereo mini jack.
 For a computer which is capable of USB
 audio output, by using the 
accessory USB cable to connect the computers USB port to the USB port at 
the rear of the projector.

Tip :
 After making the connections, change the Audio Input setting in the Audio menu to 
either Audio1, Audio2 or USB, depending on which input port you are using. (P.67)
 You can also connect external speakers to the projector in order to reproduce the audio 
signals. (P.34)
 The USB cable can only be connected to computers with a standard USB interface. If 
using a computer which is running Windows, the computer must have had a full 
version of Windows 98/2000/Me installed. If the computer is running a version of 
Windows 98/2000/Me that has been upgraded from an earlier version of Windows, 
correct operation cannot be guaranteed. If using a Macintosh computer, the computer 
must be running OS9.0 – 9.1. It may not be possible to use the USB audio function 
under some versions of both the Windows and Macintosh operating systems.
 If using a USB cable to output sound from the computer, you may need to change the 
computer settings. For details, refer to the section of the documentation provided with 
your computer.
Using the Remote Control to Operate the Mouse Pointer
You can use the remote control as a wireless mouse to control the mouse pointer 
on the computer screen. To do this, you must use a mouse cable to connect the 
mouse port of the computer to the mouse port or the USB
port at the rear of 
the projector.
Example of PS/2 mouse connection
Turn off the power for both the projector and the computer before connecting 
them. If the power for either device is on at the time of connection, errors in 
operation or damage may result.
