Handling Instructions
Do not support the monitor within
the screen area. The Liquid Crystal
Display is glass and can be damaged
by rough handling or excessive
pressure.
1. Lift the monitor by placing your hands where indicated below.
2. Before using your monitor for the first time, remove the clear
protective film from the front of the screen.

Workplace Preparation
This section gives advice on
what you should consider
before you set up your monitor.
Height
Position the monitor so that the top of the screen is slightly below your eye
level when you sit at your workstation.
Orientation
Choose a position that gives the least reflection from lights and windows,
usually at a right angle to any windows. Position the monitor directly in
front of you so that you do not have to twist your body to use it. Tilt the
monitor to a comfortable viewing angle.
Adjusting the Monitor Position
The monitor offers the adjusting height, rake, and rotation possibility that
enable the monitor to be optimally adjusted for the respective user and the
respective situation.
T120
You can tilt the screen backward and forward, as well as lift up and
down as shown below:
Working Practices
This section gives advice on
how you can work comfortably
and reduce fatigue.
Rest
Take regular breaks. Vary your posture, stand up and stretch occasionally
as prolonged use of computer workstations can be tiring.
4
Back
Sit back in your chair and use the backrest.
ENGLISH
Hands
Adjust the seat height so that your forearms are approximately horizontal
and your wrists are straight when using the keyboard. Your upper arms
should be relaxed with your elbows near your body.
Use a light touch on the keyboard, keeping your hands and fingers
relaxed. Allow a space in front of the keyboard to rest your wrists when
not typing. Consider using a wrist pad.
Eyesight
Working with monitors, in common with any prolonged close work, can be
visually demanding. Look away from the screen periodically and have
your eyesight checked regularly.
Screen settings
Set the screen brightness and contrast to a comfortable level. You may
have to adjust this as the lighting changes during the day. Many
application programs let you select color combinations which can help you
to view in comfort. See the User controls section on page 15 for more
information.
Caring for your Monitor
Be sure to turn off the power before you perform any maintenance on the
monitor. Clean your monitor as follows:
Gently wipe the device covers and the screen with a soft cloth.
Remove finger marks and grease with a damp cloth and mild
Never use flammable cleaning material to clean your IBM monitor or
detergent; do not use solvents or abrasives.
any other electrical apparatus.

Connecting your Monitor for Analog
Be sure to read the 'Safety'
Information located in the Monitor
Safety and Warranty Guide before
carrying out this procedure.
1. Turn off your computer and all attached devices.
2. Tilt the monitor all the way forward.
3. Connect the analog signal cable to the VGA video port on the back of
your computer.
This port might be directly attached to your computer (figure A), or it might
be part of a video adapter card (figure B). The analog video port on your
computer or video adapter card is normally blue to match the blue
connector on your monitor’s analog video cable.
4. Attach the power cord at the back of the monitor where it says “AC
IN”. The arrow in the drawing below indicates the approximate area:
Insert the power plug into a properly grounded electrical outlet.

The
only applies to the current
screen mode. When a new
mode is selected, repeat this section
to reset the monitor.
AUTO SETUP process
Auto setup is not required when using digital input
When you first use your monitor you must perform Auto Setup. This
procedure sets up your monitor to process the video signals from your
computer without image discoloration or smearing. After you perform Auto
Setup, the settings are stored and used each time you turn on the
monitor.
To optimize the displayed image a set-up utility is provided on the CD.
Operation of the utility is dependent on the operating system on your
computer. For correct operation locate the operating system on your
computer from the table below and follow the appropriate instructions.

Auto Setup for DOS
If the monitor is in power
saving mode, it may
automatically turn off while
you are waiting for it to warm up. If
this happens, switch off the monitor
and switch it on again after a few
seconds.
If you are using PC-DOS/V,
change to U.S. mode by typing
‘CHEV US’ and pressing
ENTER at the command prompt.
The size and diversity of the
dot pattern varies with the
screen resolution.
To set up the monitor automatically in DOS, do the following:
1. Turn on the monitor first; then turn on the computer.
If the message Attention No Signal is displayed, or if nothing is
displayed, check:
• That the video interface cable is connected properly.
• The correct video adapter card is installed.
• The correct supported display mode is selected for your computer.
2. Wait approximately 15 minutes, until the monitor warms up.
3. Insert the User’s Guide and Installation Files CD into the computer
CDROM drive.
4. Display the command prompt screen of the DOS full-screen display.
5. Type d:\ (change the drive letter to match your CD-ROM drive if it is
not drive D).
6. Type TESTPATD and press ENTER.
7. Select from the screen the number for the color or text mode you
want to set up.
8. Select from the screen the number for the video mode you want to
set up. You can repeat this process for as many of the color and
video modes as you need.
9. When the dot pattern appears, press the AUTO button at the bottom
of the monitor. This activates the
AUTO SETUP procedure, which will
optimize the display settings with the provided dot-patterns.
The screen will momentarily turn black while auto adjustment
proceeds.
10. When finished, the Auto Adjustment menu disappears and the
screen returns to a normal display.
11. Press the ESCAPE key to exit the test pattern program.
12. Type
at the command prompt to return to Windows.

General Information
ENGLISH
Display modes
The display mode the monitor uses is controlled by the computer.
Therefore, refer to your computer documentation for details on how to
change display modes.
The image size, position and shape might change when the display mode
changes. This is normal and the image can be readjusted using
SETUP
and the monitor controls.
Unlike CRT monitors, which require a high refresh rate to minimize flicker,
TFT technology is inherently flicker-free. If possible, configure your
computer for 1600 ×1200 address ability at 60Hz vertical refresh rate.
For the display modes listed on the next page, the screen image has been
optimized during manufacture.
AUTO
20
To optimize image quality,
you may want to run AUTO
Setup after switching
between modes shown in this
section. AUTO SETUP can fix the
problems in most cases. See Auto
Setup for DOS on page 13 for
details.

Power Management
If your computer has
previously been used with a
CRT monitor and is currently
configured to a display mode
outside the range that the Flat
Panel monitor can display, you may
need to re-attach the CRT monitor
temporarily until you have
re-configured the computer,
preferably to 1600 x 1200 at 60Hz.
To benefit from power management, the monitor must be used in
conjunction with a computer that implements the Video Electronics
Standards Association (VESA) Display Power Management Signalling
(DPMS) Standard.
The power management feature is invoked when the computer recognizes
that you have not used your mouse or keyboard for a user-definable
period. There are several states as described in the table below.

Notice: This mark applies only to countries within the European Union (EU) and Norway.
This appliance is labeled in accordance with European Directive 2002/96/EC concerning waste electrical
and electronic equipment (WEEE). The Directive determines the framework for the return and recycling of
used appliances as applicable throughout the European Union. This label is applied to various products to
indicate that the product is not to be thrown away, but rather reclaimed upon end of life per this Directive.
In accordance with the European WEEE Directive, electrical and electronic equipment (EEE) is to be
collected separately and to be reused, recycled, or recovered at end of life. Users of EEE with the WEEE
marking per Annex IV of the WEEE Directive, as shown above, must not dispose of end of life EEE as
unsorted municipal waste, but use the collection framework available to customers for the return,
recycling, and recovery of WEEE. Customer participation is important to minimize any potential effects of
EEE on the environment and human health due to the potential presence of hazardous substances in
EEE. For proper collection and treatment, contact your local IBM representative.
