CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTION

2 – 1

Caution:

•  Be sure to turn off the main power switch and disconnect the plug

from the power outlet before connecting/disconnecting cables.

Also, read the manual of the equipment to be connected.

•  Be careful not to mix up the input terminal with the output terminal

when connecting cables. Mixing up the input and output terminals

may cause malfunctions and the other problems.

•  Use a commercially available signal cable (DVI-D 24 pin) for the PC1

input terminal. Set DVI SELECT on the OPTION menu to PC (DIGI-

TAL) when using the PC1 input terminal.

•  Use a commercially available signal cable (Mini D-sub 15 pin) for the

PC2 input terminal.

• Use a commercially available signal cable (BNC) for the PC3 input

terminals. Set BNC SELECT on the OPTION menu to PC (ANALOG)

when using the PC3 input terminals.

• Use a commercially available audio cable (mini stereo jack) for the

PC audio input terminal. Use an audio cable without resistance.

Note:

•  Images may not be displayed properly depending on the computer

(graphics board) to be connected.

•  A screen with 1920 

×

 1080 resolution may not be displayed cor-

rectly on PC3 (BNC). In this case, check the settings of your com-

puter (graphics board) to verify that input signals conform to

specifications of this monitor (Hsync: 66.3 kHz, Vsync: 60 Hz, and

Dot frequency: 148.5 MHz).

•  If there is a check box to disable EDID in display control panel,

check it when using PC3 (BNC).

•  Use the automatic screen adjustment when a PC screen is dis-

played for the first time using PC2 or PC3, or when the setting of

the PC is changed.

•  The screen is adjusted automatically when SELF ADJUST in the

OPTION menu is set to “ON”.

•  Use a commercially available signal cable (DVI-D 24 pin) for the AV1

input terminal. Set DVI SELECT on the OPTION menu to AV (DIGI-

TAL) when using the AV1 input terminal.

• Use a commercially available component cable (BNC) for the AV2

input terminals. Set BNC SELECT on the OPTION menu to AV
(COMPONENT) when using the AV2 input terminals.

•  Use a commercially available video cable (BNC) for the AV3 input ter-

minal.

• Use a commercially available audio cable (RCA) for the AV audio

input terminals.

•  The AV1 input terminal is compatible with the video signals below:

1920

• Audio from the equipment connected to the AV audio input terminals

or PC audio input terminal is output. Connect to the audio input termi-
nals of the connected equipment using a commercially available

audio cable (RCA).

•  The audio output varies depending on the input mode selection. 

•  The volume level can be adjusted using the volume adjustment.

• Selecting FIXED of “AUDIO OUTPUT” from the OPTION menu fixes

the volume of sound output from the audio output terminals.

• Audio signals output from the PC/AV audio output terminals cannot

be adjusted using the AUDIO menu.

Video signals from PC1 and AV1 can be output to HDCP-compatible
external device. Use this terminal when you connect multiple moni-

tors in a daisy chain via DVI cable (commercially available). 

Images cannot be output to device that is not HDCP-compatible.

You can control the monitor from a PC by connecting a commercially

available RS-232C straight cable between this terminal and the PC.

Be sure to use external speakers with an impedance of 6 

Ω and a rated

input of at least 7W.

1) While pushing the tab, insert the tip of the cable.

2) Release the tab.

Note:

•  Be sure to connect the 

+

 and 

−

 terminals and the left and right

speakers properly.

•  Avoid short circuiting the 

+

 and 

−

 terminals.

You can connect multiple monitors (up to 5 monitors) in a daisy chain by

using the PC1/AV1 input terminals and PC/AV output terminals of this
monitor.

[Connection example]

Note:

•  The length of the signal cables or surrounding environment may

affect the image quality.

•  The screen may not display properly when using terminals other

than PC1/AV1 for the input mode. In this case, turn off the power to

all the monitors connected in a daisy chain and then turn the power
on again.

You can control this monitor from a PC via RS-232C (COM port) on the
PC. You can also connect multiple monitors via a daisy chain by using a
PC. By assigning ID numbers to each monitor, you can make input
mode selection/adjustment or can check the status of a specific monitor.

■ PC connection

Connect with RS-232C straight cable between the PC’s COM port
(RS-232C connector) and the RS-232C input terminal on the rear of the
monitor.

Connect with RS-232C straight cable between the PC’s COM port
(RS-232C connector) and the RS-232C input terminal on the rear of the

first monitor.

Next, connect RS-232C straight cable to the first monitor’s RS-232C
output terminal and to the second monitor’s RS-232C input terminal.

Connect in the same way to the third and subsequent monitors.

Up to 25 monitors can be connected. (Depending on the length of the
cable used and the surrounding environment.) 

■ Communication conditions

Set the RS-232C communication settings on the PC to match the

monitor’s communication settings as follows:

■ Mounting precautions

•  Since the monitor is heavy, consult your dealer before installation.

• When installing or moving the monitor, ensure that this is carried out

by at least 2 people.

•  When moving the monitor, be sure to hold it with the handles both on

the rear and the unit bottom. Do not hold the LCD panel. This may

cause product damage, failure, or injury.

•  Install the monitor with the surface perpendicular to a level surface. If

necessary, limit the tilt between 0 and 20 degrees downward.

• Mounting the monitor on the wall requires special expertise and the

work must be performed by an authorized SHARP dealer. You should

never attempt to perform any of this work yourself. Our company will

bear no responsibility for accidents or injuries caused by improper

mounting or mishandling.

•  This monitor should be used at an ambient temperature between 0°C

and 40°C. Provide enough space around the monitor to prevent heat

from accumulating inside.

If it is difficult to provide such space because the monitor is 

installed inside a housing or for other reasons, take other measures

to keep the ambient temperature between 0°C and 40°C such as

installing a fan in the housing.

•  Do not block any ventilation openings. If the temperature inside the

monitor rises, this could lead to a malfunction.

•  After mounting, it is recommended to take some measures to pre-

vent the monitor from falling down. Secure the monitor by fastening

the hooks at the top of the monitor to a wall or a pillar with strong

cord and brackets (not included).

•  Do not place the monitor on a device which generates heat.

•  This monitor is fixed to the temporary stand when shipped from the

factory. Please note that this stand is for temporary use only until

the monitor is properly mounted.

•  Be sure to use a stand or a wall-mount/ceiling-mount bracket

designed or designated for mounting the monitor.

•  This monitor is designed to be installed on a concrete wall or pillar.

Reinforced work might be necessary for some materials such as

plaster / thin plastic board / wood before starting installation.

This monitor and bracket must be installed on a wall which can

endure at least 4 times or more the weight of the monitor. Install by

the most suitable method for the material and the structure.

Prepare wall-hanging brackets or a stand to mount the monitor unit.

Read the manual for the brackets or stand for the proper mounting pro-
cedure. (The screw holes for mounting brackets (M10 x 4 holes) are

provided on the rear of the monitor.)

Caution:

•  The monitor is heavy. It must be handled by 2 or more people.

• This monitor is fixed to the temporary stand when shipped from the

factory. Please note that this stand is for temporary use only until the
monitor is properly mounted.

1)  Hold the monitor with the handles to prevent it from falling down,

and remove the stand fixing screws (4).

2)  Lift the monitor by holding it with the handles and the underside of

the unit.

3)  When the installation is complete, attach the included stand hole

protection covers, using the supplied screws.

(1)  Fold the sheet perpendicularly with the adhesive side inward.

(2)  Remove the adhesive cover and attach the sheet to the monitor.

• The temporary stand is specifically designed for this monitor. Do not

use for other devices.
