Connecting a computer sourceRequired computer connectionsConnect one end of the provided computer cable (see page 15 for connect-
ing video devices) to the blue M1-DA connector on the projector. Connect 
the other ends (USB and VESA) to the USB and VGA ports on your com-
puter. If you are using a desktop computer, you will need to disconnect the 
monitor cable from the computer ’s video port first. 
This connection allows you to advance slides in a PowerPoint presentation 
using an optional remote. USB drivers must be installed to use the USB fea-
ture. 
For more information, see page 14.
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 (not 
included) to your computer and to the red and/or white Audio In connec-
tors on the projector.

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 20.
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 13 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 21.

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 or Windows ME, skip these steps and go 
to “Adjusting the image” on page 12.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 connect the audio to your stereo system via 
the Audio Out connector.
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 33 for more information.What is Aspect Ratio?Aspect ratio is the ratio of the image width to image height. HDTV and 
most DVDs are 16:9, which is the default for this projector. This projector is 
not intended for use with 4:3 screens. When in 4:3 mode the projector places 
black bars on both sides of the image. Native mode centers the image and 
turns off the internal scaler so that any resolution larger than 854x480 is 
cropped on the edges. Letterbox expands the image to fill the screen.
If you are projecting onto a screen, the size/shape of the screen may deter-
mine 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. For example, 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 and 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 or Native 
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 (RCA) video connectionPlug the provided composite A/V cable’s yellow connector into the video-
out connector on the video device. Plug the other yellow connector into the 
yellow Video 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 are not as high 
quality as S-video or component video.S-video connectionIf your video device uses a round, seven-prong S-video connector, plug the 
S-video cable 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, but not as high as component video.

Component (RCA) connectionTo connect a progressive scan DVD or HD source, use the component con-
nector. Connect a component video cable with red, green, and blue RCA 
connectors (available at Consumer Electronic stores) into the source device’s 
component connector. Connect the other three ends of the component cable 
into the Component connector on the projector.
Use the composite 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).
Keep in mind that component video delivers higher quality video output 
than s-video or composite video.DVI connectionIf your video device uses a DVI connector, plug the DVI end of the M1-D 
cable (sold separately) into the video-out connector on the video device. 
This connector may be labeled “To Monitor” on the video source. Plug the 
M1 computer end of the cable into the M1-DA connector on the projector. 
Use the composite 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).
Keep in mind that DVI video delivers the highest quality video output.
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.
