chip supports computer display formats.
To project images output from a computer, the computer’s
external monitor signal must be set at a refresh rate (vertical
frequency) that’s compatible with the projector; see the
following table for compatible formats. For best results, the
computer’s resolution should be set to 1024

Positioning the Projector
Follow these guideline when deciding where to place the
projector:
❏ 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 it on top of anything
that could block the vents under the projector.
❏ Make sure the projector is within 10 feet of a grounded
electrical outlet or extension cord.
Image size increases with distance, but varies depending on
how you’ve adjusted the optical zoom and other settings.
TBD
Calculating Image Size and Projection Distance
Use the formulas below either to find out how large your
image will be when you know the distance from the projector
to the screen, or to find out how far from the screen to place
the projector if you want an image of a certain size. Since the
size of the image can be changed by rotating the zoom ring,
formulas are given for calculating both the minimum and
maximum sizes.
Note: The formulas given here are for when the projector is placed
flat, without tilting it up at the screen. If you tilt it up by
extending the feet or use electronic keystone correction, your image
size may vary.
Wide Throw Zoom Lens (V12H004W03)
To determine the diagonal size of an image (in inches) when
you know the projection distance:
❏ Maximum diagonal size =
(((2.54
×
projection distance) / 100)
❏ Minimum diagonal size =
(((2.54
×
projection distance) / 100)
To determine the projection distance (in inches) when you
know the diagonal size of the screen image:
❏ Maximum projection distance =
(((diagonal size – 1.29) / 26.84)
❏ Minimum projection distance =
(((diagonal size – 2.13) / 36)

from screen
It’s best to place the projector directly in front of the center of
the screen, facing the screen squarely. If it isn’t placed this
way, the image will be “keystone” shaped, instead of
rectangular.
Screen
Projector
Overhead View
If you place the projector below screen level, you’ll have to tilt
it up by extending the front adjustable foot. This also causes
the image to lose its rectangular shape. To correct distortion,
see “Adjusting the Image Shape” on page 7.
Middle Throw Zoom Lens (V12H004M03)
To determine the diagonal size of an image (in inches) when
you know the projection distance:
❏ Maximum diagonal size =

Connecting the Projector
You can connect the projector to three computer sources or
four video sources—up to a total of four sources altogether.
You can include an independent sound channel for each
source. (See the Quick Setup poster or the User’s Guide for
complete setup instructions.)
Note: The preview featu re lets you see all the sources at a glance,
so you can easily switch among them. See page 5.
Types of Connections
The following types of connections are possible, depending on
the kinds of signals your equipment generates and its available
output ports.

The projector should automatically detect the correct source.
Note: If it fails to detect the source, make sure the

and BNC Input options in the Setting menu are set to
Auto. See the User’s Guide for more information.
Computer
If necessary, you can switch to the correct source by pressing
the corresponding source button on the remote control or
projector. See page 5 for details.
Playing Sound Through the Projector
You can play sound through the projector’s speaker system or
you can attach an external speaker system.
You can use either of these commercially available audio
cables:
❏ If your computer or video equipment is connected to the
Computer or DVI port, use a stereo mini-jack cable.
❏ If your equipment is connected to the
port, or to the
BNC ports, use an RCA-style audio cable.
Video or S-Video
Using the Remote Control as a Wireless Mouse
If you’ve connected a computer to the projector, you can
use the projector’s remote control as a wireless mouse by
connecting a USB cable to both the projector and your
computer. The wireless mouse function is supp orte d on
systems with a USB port running Windows XP, 98, 2000, or
Me; or Macintosh OS 8.6 to OS X 10.2. See the User’s Guide
for details.
Viewing Images on an External Monitor
You can use an external monitor to display images from any
connected computer source. This lets you view your
presentation close-up, as well as on the projection screen.
Note: Some LCD monitors may not be able to display the image
correctly. If you have trouble displaying the image, connect a
multiscan monitor. If you’re projecting computer images, make
sure the computer’s refresh rate is set to 65 Hz or greater.
The Monitor Out port will not display images from a video
source.

Epson PowerLite 7900p Projector
To use an external monitor, connect it to the projector’s
Monitor Out port, as shown:
External monitor
Follow these guidelines when using an external monitor:
❏ The monitor displays the currently selected computer
source. Press the
Preview button on the remote control if
you want to display all the active sources at once (see
“Previewing Image Sources” on this page).
❏ If you want, you can view (or preview) images on the
monitor while the projection screen is darkened by pressing
the
A/V Mute button.
❏ You can also view images on the monitor while the
projector is in standby mode (plugged in but not turned
on). Set the
Standby Mode setting to Network ON in the
Advanced1 menu.
Displaying an Image
If you turn on your computer or video equipment before
turning on the projector, the projector automatically selects
the connected source. If you turn on the projector first or you
have multiple sources connected, you may have to switch to
the desired source manually (see “Selecting the Image Source”
on this page).
Turning On the Projector
1. Remove the lens cap.
2. Plug in the projector.
3. Wait a few seconds until the P

(in about 20 seconds), the projector is ready for use.
Warning: Never look into the lens when the lamp is on. This
can damage your eyes.
5. If you’ve connected a Windows-based computer to the
projector, you may see a New Hardware Wizard saying
your computer has found a plug-and-play monitor; if so,
click
Cancel.
Selecting the Image Source

❏ Make sure the cables are connected correctly.
❏ Make sure the P
the lens cap is off.
❏ If you’ve connected more than one computer and/or video
source, you may need to press one of the
on the projector’s control panel or the remote control to

The Projector and Computer Don’t Display the Same Image
If you don’t see the same image on the projection screen and
on your computer screen, follow these guidelines.
If you’re using a Windows notebook computer:
❏ On most systems, there’s a function key that lets you toggle
between the LCD screen and the projector, or display on
both at the same time. It may be labeled
an icon such as . You may have to hold down the
key while pressing it. Allow a few seconds for the projector

❏ If the function key doesn’t permit you to display
simultaneously on both screens, you should check your
monitor settings to make sure both the LCD screen and the
external monitor port are enabled. From the Control Panel,
open the
box, click the
Display utility. In the Display Properties dialog
Settings tab, then click Advanced. The
method for adjusting the settings varies by brand; you may
need to click a

2. Once the image is positioned where you want it, release the
lever to lock the foot in position.
3. If necessary, you can finetune the height by turning
the projector’s rear feet.

Raising the projector may cause the im age to distort or
“keystone.” See the next section to correct this.
Adjusting the Image Shape
In most cases, you can maintain a rectangular image by
placing the projector directly in front of the center of the
screen with the base of the lens level with the bottom of the
screen.
Even if the projector is slightly tilted (within a range of 40° up
or down), the projector’s automatic keystone correction
function detects and corrects vertical keystone distortion.
