■■■■ DDC (Plug & Play)
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.

Caution:
• Pressure from hands on the LCD panel could cause damage.
• Be careful not to allow your fingers to be pinched.
1) Height adjustment
Adjust to an easy to view height.
Approx. 60mm
3) Rotation (long height/width)
The display can be rotated for a long height or width to suit the displayed content.
• 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.
• 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.
To set to long height
Gently turn in the clockwise direction (to 90°).

CHAPTER 2. CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS
1. CONNECTING THE MONITOR AND TURNING THE MONITOR ON AND OFF
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.
2. Run cable along the back of the stand.
Pass cable in front of the stand, and then bring it through the back.
3. Refit the cover.
Be careful not to pinch the cable.
• 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.)
• 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.
• 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
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 (comm ercially available)
and the digital signal cable to the 2-input cable.
Macintosh conversion adapter
Note: If connecting to the Sun Ultra series, a conversion adapter (com-
mercially available) may be required.
■■■■ Digital connection
Connect the digital signal cable to the digital RGB output terminal of the
computer.
• For digital RGB connection, the monitor has an input for connecting
to a computer with a DVI-compatible output connector (DVI-D 24 pin
or DVI-I 29 pin) and UXGA output capability.
(Depending on the type of computer to be connected, the display may
not work correctly.)
• Use the accessory digital signal cable or an NL-C04J cable (sold separately).
If using other commercially available digital signal cables, correctly
display may not be achieved. UXGA resolution m ay not be av ailable
when using the NL-C01E digital signal cable.

■■■■ Arms or stands able to be used
Attachments must satisfy the following.
• Compatible with the VESA standard.
• Have a gap of 100 mm x 100 mm between the screw holes on the
section to be attached.
• Not be likely to fall off or break off after being attached to the monitor.
■■■■ 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.
4. Remove the four screws and then remove the stand from the monitor.
Note:
• The stand is specially made for use with this monitor. Once having
removed the stand, never attempt to attach it to another device.
• 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.
Caution:
Do not disassemble the stand. Parts may spring out and cause
injury.
5. Attach the arm to the monitor with the four screws.
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.
LL-T2020 CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS
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.
