Important Safety Information
WARNING: Never look into the projector lens when the lamp is turned on; the bright light can damage your eyes.
Never let children look into the lens when it is on. Never open any cover on the projector, except the lamp and
filter covers. Dangerous electrical voltages inside the projector can severely injure you. Except as specifically
explained in this User’s Guide, do not attempt to service this product yourself. Refer all servicing to qualified service
personnel.
WARNING: The projector and its accessories come packaged in plastic bags. Keep plastic bags away from small
children to avoid any risk of suffocation.
Caution: When you replace the lamp, never touch the new lamp with your bare hands; the invisible residue left by
the oil on your hands may shorten the lamp life. Use a cloth or glove to handle the new lamp.

Welcome
The Epson® PowerLite®7900p is a versatile, lightweight projector
designed to ensure that your presentations are easy and trouble-free,
whether you use it in the classroom or conference room. When space
is limited, you can project against a surface less than five and one-half
feet away. The projector’s keystone correction function automatically
corrects image distortion, and Epson’s unique Wall Shot™function
lets you project against blackboards and colored walls without loss
of image color, regardless of ambient lighting. In addition, the
PowerLite 7900p offers outstanding image quality, with up to 4000
lumens of brightness, a resolution of 1024 × 768 pixels, and a 700:1
contrast ratio.
Your Epson PowerLite projector can be connected to three computers
at the same time, or four video sources (up to a total of five sources at
the same time). You can include an independent sound channel for
each source. A preview feature lets you see all the sources at a glance,
so you can easily switch between them.
Use the remote control to take charge of your presentation. Freeze the
action, zoom in on part of the picture, or display a picture-in-picture
video. Use the remote as a pointer, or to draw on the screen. You can
even use it in place of your computer’s mouse to control your
computer and change slides in PowerPoint.
®
With the projector’s Easy Management™system, you can use a
Windows®PC to remotely monitor and control the projector.

10 Welcome
To prevent unauthorized use of your PowerLite 7900p, you can assign
a password, create a user logo which is displayed at startup to identify
the projector, and disable the projector’s buttons through the
Operation Lock feature. For more information about security features,
see page 77.
Getting the Most from Your Projector
Depending on your presentation, you can take advantage of any or all
of these options:
■Connecting to a notebook or other computer
If you want to connect the projector to a notebook or desktop
computer, see page 26. For additional presentation control, you
can connect the USB cable to the projector for running slide
shows, and connect an external monitor to view the presentation
on your computer simultaneously.
■Connecting to video sources
You can connect a DVD player, VCR, HDTV, camcorder, laser
disc player, digital camera, and other video sources to your
projector. See page 20 for instructions.
■Using the remote control
The remote control lets you switch from computer to video
sources, zoom in on part of your image, freeze or mute the
presentation, and adjust many other projector features. For
details, see Chapter 3.
■Including sound in your presentation
If your presentation includes sound, you can connect the audio
cable that came with your projector to use the projector’s built-in
speaker. See page 33.

Additional Components
Depending on how you plan to use the projector, you may need
additional components:
■To receive an S-Video signal, you’ll need an S-Video cable. One
may be provided with your video equipment, or you can purchase
one from Epson; see page 15.
■To receive a component video signal from a VCR or other video
device, you’ll need a component video cable. One may be
provided with your video equipment, or you can purchase one

■To receive an RGB video signal from a video device that has three
connectors labeled R/G/B, you’ll need a BNC-style video cable
(one may be included with your video equipment). See page 25
for details.
■Some older PowerBooks and Macintosh®desktop models may
need the Macintosh adapter set shown on page 30 (available from
Epson; see page 15). Older iMac®systems may need a special
adapter to provide a VGA output port; see your computer dealer.

Setting Up the Projector
This chapter gives you basic information on setting up the projector:
where to position it and how to connect it to a video source (such as a
VCR or DVD player) or to a notebook or desktop computer.
Follow the instructions in this chapter on:
■Positioning the projector
■Connecting to video equipment
■Connecting to a computer
■Connecting an external monitor
■Playing sound through the projector

18 Setting Up the Projector
Positioning the Projector
If you’re setting up the projector yourself and it isn’t already installed
in the theater or conference room you’re using, you’ll probably want
to place it on a table in front of the screen, as shown. x art below
This lets you stand in the front of the room, face the audience, and
remain close enough to the equipment to be able to control it. Try to
leave as much space as possible between the projector and the screen to
get a good-size image.
Use the figure below to help you determine placement. Image size
increases with distance, but can vary depending on how you position
the zoom ring and whether you’ve adjusted the image with other
settings.
Also keep these considerations in mind:
■Place the projector on a sturdy, level surface.
■Make sure there is plenty of space for ventilation around and
under the projector. Do not set the projector on top of loose
papers that could block the vents under the projector.
■Make sure the projector is within 10 feet of a grounded electrical
outlet or extension cord.
note
You can mount the projector
on the ceiling, or place it
behind a translucent screen
for rear projection. See
page 123 for details.
2.5 to 3.5 ft7 to 9.5 ft27 to 36.5 ft distance from screen
TBD

Setting Up the Projector 19
Ideally, you should place the projector directly in front of the center of
the screen, facing it toward the screen squarely. The base of the lens
should be at about the level of the bottom of the screen.
If you place the projector below screen level, you’ll have to tilt it up by
extending its feet. This causes the image to become “keystone” shaped,
but you can correct the distortion by pressing the Sync buttons on the
projector. See page 44 for detailed information about correcting the
image shape.
For instructions on installing the projector in a permanent location,
such as a theater or conference room, see page 123.
note
After positioning the
projector, you may want to
connect a Kensington
MicroSaver®anti-theft
device to the lock port on the
projector’s left side. You can
purchase this from Epson;
see “Optional Accessories” on
page 15.

20 Setting Up the Projector
Connecting to Video Equipment
You can connect up to four video sources to the projector at the same
time. Before starting, look at your video equipment to determine its
available video-output connections:
■If your video player has a yellow RCA-style video output
connector, see “Connecting a Composite Video Source” on
page 21.
■If your video player has an S-Video connector, see “Connecting
an S-Video Source” on page 22.
■If your video player has a component video port (three connectors
labeled either Y/Cb/Cr or Y/Pb/Pr), see “Connecting a
Component Video Source” on page 23.
■If your video player has an RGB video port (either a single
connector for a VGA-style monitor cable, or three connectors
labeled R/G/B), see “Connecting an RGB Video Source” on
page 24.
After connecting the video cables, you may also want to connect an
audio cable to play sound through the projector; see page 33.
