Connecting to the USB Port
You can connect a Windows XP or Windows 2000 (SP4) computer to 
the projector’s Type B (square)  USB port and project your

software from the projector installs on your computer. 
1. Follow the instructions beginning on page 17 to turn on the 
projector and adjust the image.
2. Make sure the USB Type B setting under the projector’s 
Extended menu is set to 
USB Display (see page 150).

your notebook or desktop computer.
Messages appear as the projector is recognized and the software 
installation begins.
7. Follow the instructions on your computer screen to install the 
Epson USB Display software. If you see a “Digital Signature 
Warning,” select 
Continue. You will need to install the software 
only the first time you connect.

under the projector’s Extended menu to 
Wireless Mouse (see 
page 150), 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 20 feet 
(6 meters) away.

Connecting to Video Equipment 
You can connect several 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 45.
■If your video player has an S-video connector, see “Connecting an 
S-Video Source” on page 46.
■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 47.
■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 48.
After connecting video cables, you may also want to connect an audio 
cable to play sound through the projector; see page 50.
