You can connect the projector to three computer sources or 
four video sources—up to a total of four sources altogether. 
You can include an independent sound channel for each 
source. (See the Quick Setup poster or the User’s Guide for 
complete setup instructions.)

The following types of connections are possible, depending on 
the kinds of signals your equipment generates and its available 
output ports.

Note that the projector’s Computer and BNC ports accept a 
variety of input signals. If you’re connecting to one of these 
ports, you’ll need to make sure that the correct input signal 
setting is selected, or your image won’t display properly. 

To change the input signal setting, do the following:

1. After turning on the projector, press the 

Menu

 button. The 

menu screen appears.

2. Select the 

Setting

 menu.

3. Change the 

Computer Input

 or 

BNC Input

 setting as 

needed to match the signal generated by your computer or 
video equipment. (See the User’s Guide for more 
information.)

You can also cycle through the settings by repeatedly pressing 
the source button for your device on the remote control.

You can play sound through the projector’s speaker system or 
you can attach an external speaker system.

Two types of audio cables are included with the projector: 

❏ If your computer or video equipment is connected to the 

Computer

 or 

DVI

 port, use the stereo mini-jack cable.

❏ If your equipment is connected to the 

Video

 or 

S-Video

 

port, or to the 

BNC

 ports, use the RCA-style audio cable.

If you’ve connected a computer to the projector, you can use 
the projector’s remote control as a wireless mouse by 
connecting the USB cable that came with the projector. 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. See the User’s Guide for more 
information.

You can use an external monitor to display images from any 
connected computer source. This lets you view your 
presentation close-up, as well as on the projection screen. 

To use an external monitor, connect it to the projector’s
