1Connect a DVI to 15-pin D-sub
adaptor to the projector.
2Connect the above adaptor to
an RGB cable.
3Connect the above cable to the
computer.
•Secure the connectors by tightening the
thumbscrews.
Note
•Refer to “Computer Compatibility Chart” on
page 66 for a list of computer signals
compatible with the projector. Use with
computer signals other than those listed may
cause some of the functions not to work.
•When connecting the projector to a com-
puter in this way, select “RGB” for “Signal
Type” on the OSD menu or press 
 on
the remote control. (See page 52.)
•A Macintosh adaptor may be required for
use with some Macintosh computers.
Contact your nearest Sharp Authorized
Service Center or Dealer.
•Depending on the computer you are us-
ing, an image may not be projected unless
the signal output setting of the computer is
switched to the external output. Refer to
the computer operation manual for switch-
ing the computer signal output settings.

RGB output Terminal
(DIGITAL INPUT)
1Slide the “DIGITAL INPUT
TYPE” switch on the back ter-
minal board to “PC”.
2Connect a DVI cable to the pro-
jector.
3Connect the above cable to the
computer.
•Secure the connectors by tightening the
thumbscrews.
Note
•Select DIGITAL INPUT mode when con-
necting to digital output terminal of the
computer. (See page 31.)
•Before switching the “DIGITAL INPUT
TYPE” switch and connecting, be sure to
unplug the power cord of the projector
from the AC outlet and turn off the com-
puter to be connected. After making all
connections, turn on the projector and
then the computer.
•Be sure that the computer is the last de-
vice to be turned on after all the connec-
tions are made.
“Plug and Play” function

This projector is compatible with VESA-standard DDC 1/DDC 2B. The projector and a VESA DDC
compatible computer will communicate their setting requirements, allowing for quick and easy setup.

Before using the “Plug and Play” function, be sure to turn on the projector first and the con-
nected computer last.
Note
•The DDC “Plug and Play” function of this projector operates only when used in conjunction with a
VESA DDC compatible computer.

Setup
 Caution
•Do not hold the lens when lifting, lower-
ing or rotating the projector.
•
When lowering the projector, be careful not
to get your fingers caught in the area be-
tween the Swivel Stand and the projector.
Note
•When the height or direction of the pro-
jector is adjusted, the image may become
distorted (keystoned), depending on the
relative positions of the projector and the
screen. See page 33 for details on the
keystone correction.
Using the Swivel Stand
You can adjust the angle and direction of the
projected image by using the Swivel Stand.
1Unlock the lever on the Swivel
Stand.
2Adjust the angle and direction
of the projected image as you
want by lifting up the projec-
tor and rotating the projector
on the Swivel Stand.
3Lock the lever on the Swivel
Stand.

Adjusting the Projection Distance
Setup
•Refer to pages 33 and 34 about the function of Keystone correction and placement of projector using the
correction.
•Decide the placement of the projector referring to the figures on the table and the diagram below
according to the size of your screen and input signal.

(d) Horizontal placement range when projection distance is minimum.
(e) Vertical placement range when projection distance is maximum.
(
 f ) Vertical placement range when projection distance is minimum.
Note
•The aspect ratio of the projected image shifts slightly when
the lens shift is at a position other than the top position.
•The aspect ratio of the projected image also shifts slightly
when the “H Keystone” and “V Keystone” functions are
adjusted simultaneously.
•When adjusting “H Keystone” and “V Keystone” at the same
time, the values of adjustable angles for each setting
become smaller.
•Keystone correction cannot be applied to On-screen
Display.
•When Keystone correction is applied, the resolution of image
can be deteriorated to some extent.
•There are errors of ±3% in the formulas below.

Upper and Lower Lens Shift Position
•This projector is equipped with a lens shift function that lets you adjust the projection height.
•Adjust the projection height to match the setup configuration.
•The screen can be moved maximum the length of one screen vertically using the lens shift.
Note
•Optimal image quality is produced with the projector positioned perpendicular to the screen with all feet flat and level.
Tilting or angling the projector will reduce the effectiveness of the lens shift function.

Rear Projection

Place a translucent screen between the projector and the au-
dience.

Use the projector’s menu screen to reverse the projected im-
age. (See page 56
for use of this func-
tion.)
Note
•Optimal image quality can be achieved when the projector is
positioned perpendicular to the screen with all feet flat and lev-
eled.
Projection using a mirror

Place a mirror (normal flat type) in front of the lens.
Info
•When using a mirror, be sure to carefully position both the
projector and the mirror so the light does not shine into the
eyes of the audience.
Ceiling-mount setup

It is recommended that you use the optional Sharp ceiling-mount
bracket for this installation.

Before mounting the
projector, remove the
Swivel Stand. (See pages
24 and 25 for removing and
attaching the Swivel Stand.)

Before mounting the
projector, contact your
nearest Sharp Authorized
Service Center or Dealer to
obtain the recommended ceiling-mount bracket (sold
separately). (AN-CM260 ceiling-mount bracket, AN-EP101B
extension tube for AN-CM260.)

When the projector is in the inverted position, use the upper
edge of the screen as the base line.

Use the projector’s menu screen to select the appropriate pro-
jection mode. (See page 56 for use of this function.)
