Workplace Preparation
Positioning the Monitor
Choose a suitable place to position the monitor where it is not near
fluorescent desk lighting or any equipment that produces magnetic fields
that could cause interference. Ensure that the furniture or equipment can
support the weight of the monitor. Allow at least 50mm (2 in.) ventilation
space around the 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.
- Tilt the monitor to a comfortable viewing angle.
Working Practices
Rest
Take regular breaks. Vary your posture, and stand up and stretch
occasionally as prolonged use of computer workstations can be tiring.
Back
Sit back in the chair and use the back rest.
Hands
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 wristpad.
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.
Precautions

A3
Precautions
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.
Power Cord
For safe operation, use the power cord supplied with the unit.
Notes
Do not install the monitor in a location near heat sources such as
radiators or air ducts, or in a place subject to direct sunlight, or
excessive dust or mechanical vibration or shock.
Save the original shipping carton and packing materials, as they will
come in handy if you ever have to ship your monitor.
To keep the monitor looking new, periodically clean it with a soft cloth.
Stubborn stains may be removed with a cloth lightly dampened with a
mild detergent solution. Never use strong solvents such as thinner,
benzene, or abrasive cleaners, since these will damage the cabinet. As
a safety precaution, always unplug the monitor before cleaning it.

Troubleshooting
No image appears
❐Is the power cord of the
monitor connected?
❐Is the power indicator light
on?
❐Is the power on and the
power indicator green?
❐Is the power indicator
flicking?
❐you see an "OUT OF
FREQUENCY" message
on the screen?
❐Do you see a "SELF
DIAGNOSITICS" message
on the screen?
•Check and see if the power cord is connected properly to
the power outlet.
•Press the Power button.
•Adjust the brightness and the contrast.
•If the monitor is in power saving mode, try moving the
mouse or pressing any key on the keyboard to bring up
the screen.
•message appears when the signal from the PC (video
card) is out of horizontal or vertical frequency range of the
monitor. See the 'Specifications' section of this manual
and configure your monitor again.
•This message appears when the signal cable between
your PC and your monitor is not connected. Check the
signal cable and try again.
❐Is the vertical frequency
less than 70Hz or is your
monitor set to the
interlaced mode?
❐Do you have any
magnetic material such
as adapter, or high-
voltage line near to your
monitor?
❐Do you hear a "~ding"
sound while the monitor
is flickering?
•Set the vertical frequency to 72Hz or higher, and
consult the video card user manual for instructions on
converting to a non-interlaced mode.
(You can set this option under the Display icon of the
Control Panel.)
•Remove magnetic sources, such as power adapters,
speakers, or high-voltage lines, away from the
monitor.
•Use the normal degaussing function. This function
clears the screen and reduces any screen blur that
may occur due to the surrounding magnetic field. The
screen may flicker for about 5 seconds, accompanied
by a "~ding" sound.
The screen is flickering.

A14
Troubleshooting
❐Do you see basic
discoloration (16 colors)?
❐Is the screen color
unstable or monochrome?
❐Do you see a partial
blurring on the screen?
•Set the color depth to 256 colors or higher: use 'Control
Panel' ->'Display' ->'Settings' ->'Color Palette'
•Check the connection of the signal cable.
•This happens due to interference from surrounding
magnetic fields, as created when speakers, steel
structures, or high-voltage lines are placed near the
monitor. Remove any such materials from the immediate
vicinity and use the DEGAUSS icon on the screen
adjustment menu to fix the screen.
❐Do you see the after-
image even when you
turn off the monitor?
•A premature aging of the monitor pixels may cause the
prolonged display of a single image on the screen. Be
sure to use a screen saver to maximize the service life of
the monitor.
The screen color is not normal.
I see an after-image on the screen.
❐Do you see the wave
directly on the screen? •This occurs in inverse proportion to the screen focus,
which can be caused by a particular frequency or video
card. Brighten the screen and use the 'MOIRE' icon on
the screen adjustment menu to adjust the screen.
I see waves on the screen.
❐Have you installed the
monitor driver? •Be sure to install the monitor driver from the Lenovo
Monitor CD that comes with your monitor.
