Connecting a computer sourceRequired computer connectionsConnect one end of the provided computer cable (see page 16 for connect-
ing video devices) to the blue M1 Computer In connector on the projector. 
Connect the other ends (USB and VESA) to the USB and VGA ports on your 
computer. If you are using a desktop computer, you will need to disconnect 
the monitor cable from the computer ’s video port first (you can connect this 
monitor cable to the Monitor Out connector on the projector, see below). 
This USB connection allows you to advance slides in a PowerPoint presen-
tation using the remote. USB drivers must be installed to use the USB fea-
ture. For more information, see page 15.
Connect the black power cord to the Pow e r connector on the side of the pro-
jector and to your electrical outlet.
NOTE: Always use the power cord that shipped with the projector. Optional computer connections To have sound with your presentation, connect an audio cable (optional 
cable, not included) to your computer and to the red and/or white Audio In 
connectors on the projector.
If you are using a desktop computer and want to see the image on your 
computer screen as well as on the projection screen, connect the computer ’s 
monitor cable to the Monitor Out connector on the projector.

Displaying a computer source image Remove the lens cap.
Toggle the Pow e r switch on the side of the projector to the On position.
The LED flashes green and the fans start to run. When the lamp comes on, 
the start up screen displays and the LED is steady green. It can take a 
minute for the image to achieve full brightness. 
? No start up screen? Get help on page 21.
Turn on your computer.
The computer ’s image should appear on the projection screen. If it doesn’t, 
press the Computer button on the projector ’s keypad. 
If your computer has Windows 98 as its operating system, see “Using the 
projector with Windows 98 for the first time” on page 14 regarding the 
driver setup process.
Make sure your laptop’s external video port is active. 
Many laptops do not automatically turn on their external video port when a 
projector is connected. Usually a key combination like FN + F8 or CRT/LCD 
key turns the external display on and off. Locate a function key labeled 
CRT/LCD or a function key with a monitor symbol. Press FN and the 
labeled function key simultaneously. Refer to your laptop’s documenta-
tion to learn your laptop’s key combination. 
? No laptop image? Try pressing the Auto Image button on the key-
pad. Get help on page 22.

Using the projector with Windows 98 for the first 
timeThe first time you connect a computer running Windows 98 to the projector, 
the computer recognizes the projector as “new hardware” and the Add 
New Hardware Wizard appears. Follow these instructions to use the Wiz-
ard to load the correct driver (which was installed with your Windows 
operating system).
If you are running Windows 2000, Windows ME, or Windows XP, skip these 
steps and go to “Adjusting the image” on page 13.aClick Next to begin searching for the driver.bMake sure “Search for the best driver” is selected, then click Next.cUncheck any checked boxes, then click Next. Windows automatically 
locates the driver. If this driver has been removed, reload the driver using 
your Windows operating system CD.dWhen Windows finds the driver, you are ready to install it. Click Next.

For Windows 98:
 If you connected the USB cable, the Add New Hardware Wizard 
appears again. Drivers must be installed to use the USB functionality. 
The Wizard launches three times. 
The first time it detects a USB Composite Device. 
The second time a USB Human Interface Device (for the keyboard). 
The third time it detects a USB Human Interface Device (for the 
mouse). 
For Windows 2000, Windows ME, and Windows XP:
 The USB drivers are automatically installed.

Connecting a video deviceYou can connect video devices such as VCRs, DVD players, camcorders, 
digital cameras, video game consoles, HDTV receivers, and TV tuners to the 
projector. There is also an audio input via the red and white A/V connec-
tors. You can connect the audio directly to the projector to get sound from 
the built-in speaker, or you can bypass the projector ’s audio system and 
connect the audio directly from your source to a stereo or home theater sys-
tem.
You can connect the projector to most video devices that can output video. 
You cannot directly connect the coaxial cable that enters your house from a 
cable or satellite company, the signal must pass through a tuner first. Exam-
ples of tuners are digital cable boxes, VCRs, digital video recorders, and sat-
ellite TV boxes. Basically, any device that can change channels is considered 
a tuner.
Before connecting your projector, you should decide which aspect ratio you 
want to use. The projector ’s Aspect Ratio setting is accessed through the 
projector ’s Picture Menu. See page 35 for more information.What is Aspect Ratio?Aspect ratio is the ratio of the image width to image height. TV screens are 
usually 4:3, which is the default for this projector. HDTV and most DVDs 
are 16:9. If you’re projecting onto a screen, the size/shape of the screen may 
determine which aspect ratio to use. If you are projecting onto a blank wall, 
you don’t have the screen size restriction. What you plan to project will also 
help you choose between 4:3 and 16:9. Most TV shows are 4:3, while most 
movies are 16:9.
If you have a 16:9 screen then you should select an aspect ratio of 16:9 for 
anamorphic movies or HDTV, and Native for 4:3 content. If you have a 4:3 
screen you should still use 16:9 for anamorphic movies or HDTV, but you 
also have the option of using either 4:3 (to fill the screen) or Native (for 
direct pixel mapping) for 4:3 content. Keep in mind that anamorphic movies 
only appear correctly if the DVD player is set to output to a 16:9 television.

Video device connectionsComposite video connectionPlug the provided A/V cable’s yellow connector into the video-out connec-
tor on the video device. Plug the other yellow connector into the yellow 
Video 2 connector on the projector. 
Plug a white connector into the left audio out connector on the video device 
and plug a red connector into the right audio out connector on the video 
device. Plug the remaining white connector into the white audio in connec-
tor on the projector, and plug the remaining red connector into the red 
audio in connector on the projector.
Keep in mind that video output from composite connections is not as high 
quality as S-video.S-video connectionIf your video device uses a round, four-prong S-video connector, plug an 
S-video cable (available as an optional accessory) into the S-video connector 
on your video device and into the S-video connector on the projector. Use 
the A/V cable’s red and white audio connectors as described directly above 
(the yellow connectors on the A/V cable are not used).
Keep in mind that S-video delivers higher quality video output than com-
posite.

VGA connectionIf your video device has a 15-pin VGA output, plug one end of the included 
computer cable into the VGA connector on your video source. This connec-
tor may be labeled “To Monitor” on the video source. Plug the M1 computer 
end of the cable into the Computer In connector on the projector. Do not 
plug the USB end of this cable into the video device.
Use the A/V cable’s red and white audio connectors as described on the 
previous page (the yellow connectors on the A/V cable are not used).M1 to Component adapterTo connect a progressive scan DVD or HD source, use an M1 to Component 
adapter (available as an optional accessory). Connect one end of a compo-
nent cable (not provided) into the adapter. Connect the M1 end of the 
adapter into the Computer In connector on the projector.
Connect the power cord to the Pow e r connector on the side of the projector 
and to your electrical outlet.
NOTE: Always use the power cord that shipped with the projector.
