Compatible Video Formats
The projector supports NTSC, PAL, and SECAM international
video standards, as well as the monitor and HDTV display
formats listed below.
To project images output from a computer, the computer’s
video card must be set at a refresh rate (vertical frequency) that’s
compatible with the projector; see the following table for
compatible formats. If necessary, images are automatically
resized to display in the projector’s “native” format (such as
XGA for the 74c or SVGA for the 54c). In addition, the
frequencies of some computers may not allow images to display
correctly; see your computer’s documentation for details.

Positioning the Projector
Before connecting the projector, you need to decide where to
place it. The location you choose depends on the size of the
room and what you are projecting.
❏ Place the projector on a sturdy, level surface, between
2.9 and 34.4 feet from the screen.
❏ Make sure there is plenty of space for ventilation around and
under the projector. Leave at least 8 inches between the
projector and a wall.
❏ Make sure the projector is within 6 feet of an electrical outlet
or extension cord and within 5 feet of your computer and/or
video source.
❏ Place the projector directly in front of the center of the
screen, facing the screen squarely. Otherwise, your image
will not be rectangular.
Note
It’s easier to position the projector when the screen is directly in
front of the room. If the screen is placed diagonally in a corner, it’s
much more difficult to aim the projector correctly at the screen and
get a rectangular image.
Use the figure below as a guideline to help you determine how
far from the screen to place the projector. Image size generally
increases with distance, but may vary depending on how you
position the zoom ring and whether you have adjusted the
image size with other settings.
30.1 to 34.4 feet 5.9 to 6.8 feet 2.9 to 3.4 feet
To calculate exact measurements, use the following formulas:
❏ To find the projection distance when you know the screen’s
diagonal dimension:
Wide (inches) = ((3.0625
× diagonal screen size [inches]) –
2.4655) / 2.54
Tele (inches) = ((3.5063
× diagonal screen size [inches]) –
2.0063) / 2.54
❏ To find how large a screen’s diagonal dimension will be
when you know the projection distance:
Wide (inches) = (Projection distance [inches]
× 0.82937) +
0.80505
Tele (inches) = (Projection distance [inches]
× 0.7244) +
0.57219
If you place the projector below the level of the screen, you’ll
have to tilt it up by extending the feet as shown. Tilting the
projector upward causes the image to lose its rectangular shape,
but the Auto Keystone feature corrects the distortion
automatically. If the image does not regain its rectangular shape,
the Auto Keystone feature may have been disabled. To turn it
on, see page 6.

EPSON PowerLite 54c/74c Projector
If you place the projector level with the bottom of the screen,
the image will be rectangular and you won’t have to adjust it. If
you place the projector higher than the bottom of the screen,
the image will still be rectangular, but you won’t be able to fill
the whole screen with the image.
Starting Up 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 connected equipment, you may have
to select the image source manually (as described on page 5).
Follow these steps to plug in and turn on the projector:
1. Remove the lens cap.
Caution
Do not use the projector with the lens cap in place. The heat
generated by the lamp can damage the cap.
2. Connect one end of the power cord to the projector’s power
inlet. Then 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. Wait until the light stops flashing, but stays lit
orange.
3. Press the P
Power button on top of the projector or on the
remote control.

The power light flashes green as the projector warms up, and
the projection lamp comes on in about 30 seconds. The
power light stays green.
War n in g
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, turn it on or restart it. In a
few moments, you should see your computer display
projected.

❏ If you are prompted to enter a password, see “Starting the
Projector with a Password” on page 10.
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 7. Shutting down the projector
correctly prevents premature lamp failure and possible damage
from overheating.

What To Do If You See a Blank Screen
If you see a blank screen or the No Signal message after turning
on your computer or video source, try the following:
❏ Make sure the cables are connected correctly.
❏ Make sure the power light is green and not flashing and the
lens cover is off.
❏ Press the
correct source. See page 5 for more information about
selecting the image source.
❏ If you have connected a device to one of the projector’s
Computer/Component Video ports, check the
Input Signal setting in the Image menu to make sure it is
correct for the device.
If you’re using a PC laptop:
❏ Hold down the Fn key and press the function key that lets
you display on an external monitor. It may have an icon such
as or it may be labelled
for the projector to sync up after pressing it. Check your
laptop’s manual or online help for details.
On most systems, the or
between the LCD screen and the projector, or display on
both at the same time.
❏ Depending on your computer’s video card, you might need
to use the Display utility in the Control Panel to make sure
that both the LCD screen and external monitor port are
enabled. See your computer’s documentation or online help
for details.

Selecting the Image Source
If multiple devices are connected to the projector, you can
switch between them as follows:
❏ On the projector, press the
Source button until the correct
device image is projected.
❏ On the remote control, press the

select the device connected to the Computer1/Component
Video1 or Computer2/Component Video2 port. For the
S-Video or Video port device, press the
S-Video/Video

After you select a source, the screen goes dark for a moment
before the image appears. The name of the selected source (such
as
Computer1 or S-Video) appears briefly on the screen.
Adjusting the Image
Once you see your image, you may need to make certain
adjustments, as described in this section.
Focusing and Zooming Your Image
