INTRODUCTION
The In Focus®LP™750 lightweight multimedia projector com-
bines powerful and sophisticated features with easy-to-use, intui-
tive controls. Built-in multimedia features include audio, a
palette of 16.7 million colors and active matrix liquid crystal dis-
play (LCD) technology. It delivers crisp, clear XGA 1024x768
images. The LP750 is ideal for high-performance business, train-
ing and imaging applications that demand exceptional color
quality.
Image Resolution
NOTE: The projector automati-
cally expands 640x480 and
800x600 images to 1024x768.
You can display these images at
their original resolutions by turn-
ing off the Auto Resize feature.
See “Auto Resize” on page 29 for
more information.
The XGA resolution of the LP750’s projected image is 1024x768.
Screen resolutions between 1024x768 and 1280x1024 are com-
pressed to 1024x768. The projector cannot compress screen reso-
lutions above 1280x1024. If your computer’s screen resolution is
higher than 1280x1024, reset it to a lower resolution before you
connect the projector.
Compatibility
The projector is compatible with a wide variety of computers and
video devices, including:
•IBM-compatible computers, including laptops, up to 1280x1024
resolution at 75 Hz.
•Apple Macintosh and PowerBook computers up to 1280x1024
resolution.

Usage Guidelines
•Do not look directly into the projection lens when the projector
is turned on. The bright light may harm your eyes.
NOTE: If you turn the projector
off then back on again, it takes
about 30 seconds for the lamp to
light.
•Do not block the grills on the projector. Do not place the projec-
tor on cloth table coverings, as they may get sucked up to the
vents. Restricting the air flow can cause it to overheat and turn
off.
•Handle the projector as you would any product with glass
components. Be especially careful not to drop it.
•Avoid leaving the projector in direct sunlight or extreme cold
for extended periods of time. If this happens, allow it to reach
room temperature before use.
•This projector is not intended for use in a mainframe computer
room as defined in the Standard for the Protection of Electronic
Computer/Data Processing Equipment, ANSI/NFPA 75.
•Transport the projector in a vendor-approved hard or soft case.
Part numbers for these cases are listed on page 50. Call your In
Focus dealer to order.

SETTING UP THE PROJECTOR
1Place the projector on a flat surface.
•The projector must be within 10 feet (3 m) of your power
source and within 8 feet (2.4 m) of your computer.
NOTE: An optional extension
cable, sold separately, lets you
increase the distance between the
projector and your computer to
68 feet (21 m). See “Optional
Accessories” on page 50.
•If you want to project from behind a translucent screen, set
up the projector behind your screen. See “Rear Projection”
on page 32 to reverse the image.
•If you are installing the projector on the ceiling, refer to the
LP750 Ceiling Mount Installation Guide that comes with the
Ceiling Mount Kit for more information. To turn the image
upside down, see “Ceiling Projection” on page 31. The Ceil-
ing Mount Kit is sold separately; see page 50.
2Position the projector the desired distance from the screen.
•The distance from the lens of the projector to the screen
determines the size of the projected image. Figure 3 shows
three projected image sizes using the lens at maximum
zoom. For more information about image size, see “Pro-
jected Image Size” on page 56.
3Make sure the projector and your computer are turned off.

Setting up the Projector
Connecting the CableWizard™3to the Projector
CAUTION: Turn off the
computer, monitor and projector
whenever you connect or
disconnect cables.
The CableWizard3(referred to as “CableWizard” in this manual
for brevity) simplifies the connection process by providing a cen-
tral hub for all the connections between the projector and your
computer. The connectors on the CableWizard are labeled with
icons. The CableWizard also has an LED that lights solid green
when the projector is on and CableWizard is functioning prop-
erly. A slowly blinking LED indicates CableWizard is waiting to
initialize with the projector; a rapidly blinking LED indicates a
problem with CableWizard.
Connect the end of the CableWizard cable to the
connector on the projector’s connector panel (Figure 4).
NOTE: The LP750 is optimized
for use with newer CableWizards
(2 and 3). If you have a
CableWizard 1from older models
of In Focus projectors, we do not
recommend using it as image
quality is reduced. The label on the
bottom reads CableWizard or
CableWizard II or CableWizard3.FIGURE 4

Preparing to Connect Your Equipment to the Projector
NOTE: Before you continue,
make sure the projector and your
equipment are turned off. If you’re
connecting a computer, make sure
the distance between it and the
projector is 10 feet or less.
Now you’re ready to connect your equipment. Computers are
either connected to the CableWizard or directly to the projector
via the VESA connector. Video players and other equipment,
such as external speakers, are connected directly to the projector.
Steps for connecting the different types of equipment are given
on the pages listed below.
NOTE: In some older computers,
the monitor connector does not
have a hole for Pin 9. If you have
trouble connecting the CableWiz-
ard cable to your computer, con-
tact In Focus Technical Support.
