3. Make sure the DVI/VGA 
switch on the back panel is 
flipped to the right, as shown. 
If necessary, use the tip of a 
ballpoint pen to slide it over. 
4. Connect the other end of the 
computer video cable to the video port on the Macintosh. If it 
doesn’t fit, you may have to use the Macintosh desktop adapter 
included with your projector. 
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.
Replace the cover and connect the 
adapter to the free end of the computer 
video cable. Then plug the cable (with 
the adapter) into the video port on your 
Macintosh.

switch on the back panel is 
flipped to the right, as shown. 
If necessary, use the tip of a 
ballpoint pen to slide it over. 
note
PowerBook configurations 
vary, so the location of your 
computer’s ports may not 
match the illustrations. See 
your PowerBook manual for 
the port locations if necessary.

note
Some older PowerBooks may 
need a Macintosh desktop

projector) and a special 
video-out cable (available 
from Apple). Check your 
PowerBook manual to 
determine the type of 
connections needed.

							30Setting Up the Projector3. Connect the other end of the cable to the video-out port or 
monitor port
 on your Macintosh. If you can’t connect the cable to 
your Macintosh, you may need to use the Macintosh desktop 
adapter that came with your projector. 
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.
Replace the cover and connect the 
adapter to the free end of the computer 
video cable. Then plug the cable (with 
the adapter) into the video port on your 
Macintosh.
If your Macintosh requires a video-out cable, connect its larger 
end to the adapter, as shown below. Then plug the video-out 
cable into the video port on your Macintosh.
4. Tighten the screws on the connectors.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 39 for instructions.

Making Other Computer Connections
If you want to connect a computer using the BNC cable or connect a 
high-end workstation or a Digital Visual Interface (DVI) source, 
follow the instructions below.
Connecting a Computer Using the BNC Cable
Follow these steps to connect a computer to the Computer 2/
Component Video
 interface using the BNC cable:
1. Connect the VGA (D-sub 15-pin) end of the cable to your 
computer’s video port.
2. Connect the five connectors at the other end of the cable to the 
projector’s 
R/Cr/Pr (red), G/Y (green), B/Cb/Pb (blue), H/C Sync 
(horizontal sync), and 
VSync (vertical sync) ports, shown below. 
3. To display images properly, make sure the BNC parameter in the 
projector’s Setting menu is set to 
RGB. See page 69.
4. If you want to hear computer-audio through the projector, you’ll 
need an RCA-to-3.5 mm stereo cable (available for purchase from 
your electronics store or video dealer). Insert the cable’s 3.5-mm 
plug into your computer’s audio-out port. Then attach the RCA 
connectors at the other end of the cable to the 
S-Audio and 
Audio2 ports of the projector.

							34Setting Up the Projector
Connecting to a High-End Workstation
Your PowerLite projector is capable of remapping input resolutions 
up to 1600
×1200 pixels. Since 1280×1024 pixels is the default 
resolution for most leading workstations, your projector is ideal for 
displaying workstation video output.
There is no standard for workstation video output. Workstations that 
follow the SXGA standard and use the HD15 (standard VGA) 
connector won’t need an adapter cable or any special connection 
device. However, your system may vary; contact your computer dealer 
if you need help connecting your workstation.
Connecting to a DVI Video Source
The projector’s Digital Visual Interface (DVI) receives pictures 
directly from your computer in digital format. This lets the projector 
display images of greater clarity than can be achieved using a standard 
analog VGA connection. 
To project images in digital video format, follow these steps:
1. Connect the computer’s DVI cable to the projector’s DVI port. 
2. Using the tip of a pen or a small screwdriver, slide the DVI/VGA 
interface switch to the left. (If you need to use the projector’s 
VGA port again, be sure to slide the switch back to the right.)
If you want to connect audio for this computer, you can use the 
Audio port on the back of the projector.
note
You won’t be able to view 
images on a separate monitor 
when the DVI port is in use.
