These buttons are used to adjust backlight brightness.

5. Power button

This monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for carrying out Plug & Play functions on the
monitor or PC. It transfers information such as degree of resolution
between the monitor and PC. You can use this function if your PC is
DDC compliant and if it is set so that it can detect the Plug & Play monitor.
There are many varieties of DDC due to the differences between systems. This monitor works with DDC2B.

6. Power LED

This LED is lit green when in use and
orange when in power-saving mode.

7. DVI-I input terminal

The computer's digital RGB output terminal
or analogue RGB output terminal can be
connected here.
For a digital signal input: It can be connected to a computer with a DVI-compatible
output terminal (DVI-D24 pin or DVI-I29 pin)
and which has UXGA output ability.
Depending on the computer to be connected, correct display may or may not be
possible.

3) Rotation (long height/width)

Caution:
• Pressure from hands on the LCD panel could cause damage.

The display can be rotated for a long height or width to suit the displayed content.

• Be careful not to allow your fingers to be pinched.

• Before rotating, move the display to its uppermost position. If the display is rotated while it is set low, it will contact the stand and could
lead to damage.

1) Height adjustment
Adjust to an easy to view height.

• The display can only be rotated through a range of 90°. Applying
excessive force may cause malfunction.
• Do not apply excessive force when the cable is connected.
Approx. 60mm

To set to long height
Gently turn in the clockwise direction (to 90°).

1. CONNECTING THE MONITOR AND TURNING THE MONITOR ON AND OFF
3. Refit the cover.
Be careful not to pinch the cable.

Caution:
• When connecting, ensure that both the monitor and computer are
switched off.
• Be careful not to overly bend the cable or add extension cords as
this could lead to a malfunction.

Cable storage
If necessary, excess cable can be housed in the stand.
1. Remove the cover.
Gently pull the top of the cover towards yourself.

• If the cover is hard to refit, do not force it.
Check whether cables are trapped.
Caution: If the display is to be rotated, first house the cable, and then
check while gently turning the display. If it cannot be turned,
rehouse the cable with sufficient slack. (If there is insufficient
cable length, rotation will be impossible. Forcing rotation may
cause cable disconnection.)

1-1. Connecting the monitor to a computer
The accessory signal cable enables connection of two computers.
(One analog and one digital connection.)

2. Run cable along the back of the stand.
Pass cable in front of the stand, and then bring it through the back.

• To achieve an analog and digital connection for two computers, a
separately sold signal cable is required.
• The separately sold 2-input cable enables connection of two computers to the DVI-I input terminal.
• When using the 2-input cable, set the connecting input terminal
[INPUT-1] or [INPUT-2] to [2LINES] under the MODE SELECT-1
Menu.

■ Analog connection
Connect the analog signal cable to the analog RGB output terminal of
the computer.

Input terminal 1 and 2
You can connect to
either side.
• If the display is to be rotated, first house the cables with the display in the long height position, so there is sufficient length when
the display is turned.

■ When connecting using a separately sold 2-input cable

If connecting to a D-sub 15 pin 2 row Apple Power Macintosh, attach a
Macintosh conversion adapter (commercially available) to the analog
signal cable.

The separately sold 2-input cable (NL-C03J) enables connection
between the DVI-I input terminal on the monitor and the two PCs.
(One analog and one digital connection.)
1. Connect the 2-input cable to the DVI-I input terminal of the monitor,
and then connect the analog signal cable (commercially available)
and the digital signal cable to the 2-input cable.

Note:
• If a USB cable is required, please use the one included.
• Before connecting, ensure that the shape of the USB cable connector is correct.

• If the input terminal to which the computer is connected has not
been selected, the screen will not be displayed. If necessary, perform input terminal switching. (right column)

• For information regarding the USB function (such as set-up) please
refer to the operation manual of the computer to be connected.

Notes: (when using an analog signal)
• Some computers, OS and other devices may not be able to be activated. To ascertain a certain device's USB compatibility, please
contact the manufacturer of the device.

• If using the monitor for the first time or after having changed the
system settings during use, perform an automatic screen adjustment.
• When connecting to a notebook, if the notebook computer's screen
is set so that it is displaying at the same time, the MS-DOS screen
may not be able to display properly. In this case, change the settings so that only the monitor is displaying.

1-7. Instructions for attaching a VESA compliant arm

• The stand is specially made for use with this monitor. Once having
removed the stand, never attempt to attach it to another device.

An arm or stand based on the VESA standard (commercially available)
can be attached to the monitor.
Procurement of the arm or stand is at the customer's discretion.

• Once having removed the screws, store them together with the
stand and if the stand is ever re-attached be sure to use the original
screws.
Using different screws could lead to a malfunction.

■ Arms or stands able to be used
Attachments must satisfy the following.
• Compatible with the VESA standard.

Caution:

• Have a gap of 100 mm x 100 mm between the screw holes on the
section to be attached.

Do not disassemble the stand. Parts may spring out and cause
injury.

• Not be likely to fall off or break off after being attached to the monitor.
5. Attach the arm to the monitor with the four screws.

■ How to attach the arm or stand
• Be careful not to overly bend the cable or add extension cords as this
could lead to malfunction.
• While following these instructions, please also refer to the installation
instructions in the operation manual included with the arm or stand.
1. Remove the cable.
2. Spread out a soft cloth on a suitable horizontal surface.
3. Being careful not to damage the monitor, gently lay the monitor on it
display-side down.

Note: The screws used to attach the arm should be M4 screws with a
length of 6 mm ~ 8 mm protruding from the surface to be
attached. Using different screws could lead to malfunction or
may lead to the monitor falling off, internal damaged, personal
injury.

Caution:
Securely grasp both the display and stand, and gently tip over.
When the monitor is inclined, the stand may suddenly pop out and
cause injury.
