Compatible 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 match the projector’s
native resolution; 800 × 600 (PowerLite S5) or 1024 × 768
(PowerLite 77c). If this resolution isn’t available, select another
compatible format.

Positioning the Projector

Follow these guidelines to get the best results when projecting:

❏ Place the projector on a sturdy, level surface, between

3 and 34 feet (PowerLite 77c) or between 3 and 39 feet
(PowerLite S5) from the screen.

❏ 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 vent under the projector.

❏ Make sure the projector is within 6 feet (1.8 meters) of a

grounded electrical outlet or extension cord.

❏ Face the projector squarely toward the screen.

The projector supports 4 viewing setups, as shown below. If it is
installed in a rear or overhead position, you need to select the
correct projection option from the Extended menu after you
turn it on.

Table

Convenient for temporary front
projection. Choose Front from the
menu.

Front/Ceiling

Professional installation
recommended. Choose Front/Ceiling
from the menu.

Rear

For projecting behind a translucent
screen. Choose Rear from the menu.

Rear/Ceiling

Professional installation behind a
translucent screen recommended.
Choose Rear/Ceiling from the menu.

If the projector is tilted in the front or the back, you may need
to adjust the image shape. See page 7.

Image Size and Projection Distance

The distance between the projector and the screen determines
the basic size of the projected image, as shown below. The
diagrams show approximately how big your image will be, based
on where you set up the projector. Because other adjustments—
such as those made with the zoom ring—also affect the size of
the image, the numbers shown in the illustration should be
considered as general guidelines, not exact measurements.

PowerLite S5 Series

Turning On the Projector

Make sure your projector and other equipment are set up and
connected correctly. Then turn on your projector, as described
below.

If you turn on your connected computer or video equipment
before starting the projector, the projector automatically detects
and displays the image source. If you turn on the projector first,
or have multiple pieces of equipment connected, you may have
to select the image source manually. See “Adjusting the Image
and Presentation” on page 7.

Follow these steps to plug in and turn on the projector:

1. Open the

A/V Mute slide (lens cover).

PowerLite 77c

For more help determining the size of your image or where to
position the projector, try the Image Size Calculator on the
Drivers and Downloads page for your projector on Epson’s
website.

2. Connect one end of the power cord to the projector’s power
inlet.

3. Connect the other end to an electrical outlet.

The power light on top of the projector turns orange,
indicating that the projector is receiving power but not yet
turned on.

4. Turn on your computer or video source if you have not
already.

5. Press the P

Power button on the projector or remote

control to turn it on.

Power button

The projector beeps and the power light flashes green as the
projector warms up. The projector lamp comes on in about
4 seconds and the power light stays green.

Warning:

Never look into the lens when the lamp is on. This can damage
your eyes, and is especially dangerous for children.

❏ If you’re using a computer, you should see your

computer display projected after a moment or two. If not,
you need to select the image source, as described in the
next column.

(Windows only: If you see a message saying that it has
found a plug-and-play monitor, click

Cancel.)

❏ If you’re projecting a video, you may need to press the

Source Search button on the projector or remote

control to switch to your video source. Then press the
Play button on your DVD player or other device.

❏ If you are prompted to enter a password, enter it now.

To focus and adjust the image, see page 7. If a projected image
fails to appear, see “What To Do If You See a Blank Screen” in
the next column.

When you’re done with your presentation, shut down the
projector as described on page 6.

Selecting the Image Source

Selecting the image source lets you switch between images input
from different pieces of equipment connected to the projector
(such as a computer and DVD player). If you don’t see the
image you want, press the

Source Search button on the

remote control or projector until the correct device image is
projected. (The name of the selected source appears in the
upper right corner on the screen.)

Projector control panelRemote control

If a projected image fails to appear, see the next section for help.

What To Do If You See a Blank Screen

If you see a blank screen or a blue screen with the message

No Signal after turning on your computer or video source, try

the following:

❏ Make sure the cables are connected correctly to the selected

input source.

❏ Make sure the power light is green and not flashing and the

A/V Mute slide is open.

❏ Make sure you’ve selected the correct image source; see the

previous section. Allow a few seconds for the projector to
sync up after pressing the button.

❏ Check the projector’s Signal menu to make sure the correct

input source is selected. (See your User’s Guide for more
information.)

❏ Press the Help button on the projector or remote control

and select “Image is not displayed” from the menu.
