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 notebooks, 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 27.
■To connect using the BNC ports, see page 28.
■To connect using the DVI (Digital Video Interface) port, see 
page 29.
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 31
■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 notebook); see page 32
■connect an audio cable to play computer audio; see page 33 
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.
note
If you want to connect an 
external monitor to the 
Monitor Out port, your 
computer must be connected 
to either the 
Computer or 
BNC ports. The Monitor 
Out port does not support a 
DVI connection.

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 15). 
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 the instructions included with the adapter.
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.
