Chapter 2 Adjusting and using your monitor
This section will give you information on adjusting and using your monitor.
Comfort and accessibility
Good ergonomic practice is important to get the most from your personal computer
and to avoid discomfort. Arrange your workplace and the equipment you use to suit
your individual needs and the kind of work that you perform. In addition, use
healthy work habits to maximize your performance and comfort while using your
computer.
Arranging your work area
Use a work surface of appropriate height and available working area to allow you to
work in comfort.
Organize you work area to match the way you use materials and equipment. Keep
your work area clean and clear for the materials that you typically use and place the
items that you use most frequently, such as the computer mouse or telephone, within
the easiest reach.
Equipment layout and setup play a large role in your working posture. The
following topics describe how to optimize equipment setup to achieve and maintain
good working posture.
Positioning and viewing your monitor
Position and adjust your computer monitor for comfortable viewing by considering
the following items:
●Viewing distance: Optimal viewing distances for monitors range from
approximately 510mm to 760mm (20 in to 30
in) and can vary depending on ambient
light and time of day. You can achieve different viewing distances by repositioning
your monitor or by modifying your posture or chair position. Use a viewing distance
that is most comfortable for you.
●
Monitor height: Position the monitor so your head and neck are in a comfortable
and neutral (vertical, or upright) position.
If your monitor does not have height
adjustments, you might have to place books
or other sturdy objects under the base of
the monitor to achieve the desired height. A
general guideline is to position the
monitor such that the top of the screen is at
or slightly below your eye-height when
you are comfortably seated. However, be sure to optimize your monitor height so
the line of site
between your eyes and the centre of the monitor suits your
preferences for visual distance and comfortable viewing when your eye muscles are
in a relaxed stated.
●
Tilt
: Adjust the tilt of your monitor to optimize the appearance of the screen
content and to
accommodate your preferred head and neck posture.
●
General location: Position your monitor to avoid glare or reflections on the
screen from overhead lighting or nearby windows.
The following are some other tips for comfortable viewing of your monitor:
●
Use adequate lighting for the type of work you are performing.
●
Use the monitor brightness, contrast, and image adjustment controls, if equipped,
to optimize the image on your screen
to meet your visual preferences.
●
Keep your monitor screen clean so you can focus on the screen’s contents.
Any concentrated and sustained visual activity can be tiring for your eyes.
Be sure to
periodically look away from your monitor screen and focus on a far object to allow
your eye muscles to relax. If you have questions on eye fatigue or visual discomfort,
consult a vision care specialist for advice.
2-1 P27h-20 Flat Panel Monitor User’s Guide

Health Administration
Prolong exposure to computer screens may cause temporary visual fatigue. Factors
including working environment, working habit and posture, screen flicker and blue light
contribute to this condition. To minimize visual fatigue certain adjustments can be made on
the work stations or using suitable computer screens with features that alleviate eye strain.
Environment
Visual fatigue is affected by the working environment. Glare reductions and appropriate
lighting situations help minimize this condition.
●Glare reduction
Glare can be reduced by
a) Changing position of any light source that is causing the glare.
b) Fitting the light sources with appropriate diffusers or lampshade.
c) Using curtains or blind on windows to minimize glare from direct sunlight.
d) Adjusting monitor position to be perpendicular to the source of light or windows.
e) Using an anti-glare screen - ThinkVision monitors have anti-glare surface treatment that
scatters light for a reflection-free work usage.
●Lighting
Adequate lighting is necessary to avoid glare and eye fatigue. Excessive or insufficient
lighting makes the display on screen harder to see. Generally, lighting level should not
exceed 750 lux and levels ranging from 300 to 500 lux are most appropriate for computer
desk work. Recommended lighting arrangement includes positioning work stations away
from direct sunlight or using overhead lighting with baffles or louvers that reduces glare.
Working Habits
Long exposures to computer screens may cause eye strain. Symptoms include headache,
burning eyes, blurred vision and discomfort.
To minimize eye strain, computer users can
adjust working habits to let their eyes relax and recover.
●
Break Times
Computer users should take
some time away from the screen especially if working for
prolong hours. Generally, it is recommended to take short breaks (5 – 15 mins) after 1 –2
hours of continuous computer works. Taking short and frequent breaks is
more advised
than longer breaks.
●
Looking at Distant Objects
Users often blink less when in front of monitor screen. To
minimize eye strain and dryness,
users should rest the eye periodically by focusing on objects
that are far away.
●
Eye and Neck Exercises
Certain exercise reduces eye strain and prevent early onset of musculo-skeletal disorders.
It
is recommended to repeat these exercises often. However, should symptoms persists it is
recommended to consult a physician.
Adjusting and Using your monitor 2-2

Exercises for the eye:
1. Alternate looking up and looking down while keeping the body and head upright.
2. Slowly roll your eyes to look to the left and right.
3. Roll eyes to look at objects on the upper right corner and then on lower right. Do same
thing to look at objects on the upper left and lower left.
Exercises for the neck:
1. Relax arm at the side. Bend head forward to slightly stretch the neck. Hold for 5 seconds.
2. Relax arm at the side. Turn head to the right. Hold for 5 seconds. Then turn head to the
left.
3. Relax arm at the side. Swing head to the left. Hold for 5 seconds. Then swing head to the
right.
Working Posture
Appropriate working position helps minimize eye discomfort. Seating position and ideal
placement of monitor are essential for a comfortable working experience.
●Seating Position
Placing the monitor too far or too close may lead to eye strain. Far viewing distance causes
users to lean forward to see small texts, which strain the eyes and torso. Close viewing
distance, on the other hand, strains the eye resulting from exerting more effort to focus and
also causes the user to sit in awkward body
posture (i.e. tilting the head, typing with
outstretched arms, etc.)
Recommended viewing distance between the eye and the monitor screen is 1.5 x the diagonal
of the screen. Solutions in meeting this required distance in cramped office situations include
pulling desk away from wall or divider to make room for monitor, using flat panel or compact
displays placing the monitor in the desk corner, or placing the keyboard in an adjustable
drawer to create a deeper working surface.
ThinkVision monitors are design to maximize work space (e.g. having thin profiles,
compatible for ThinkCentre Tiny back mount, practical cable management, etc).
2-3 P27h-20 Flat Panel Monitor User’s Guide

●Viewing Angle
Neck fatigue and pain may result from prolong turning of the head to see objects on the monitor
screen. To minimize this, position the monitor directly in front so the head, neck and torso face
forward to the screen. It is recommended that monitor should not be more than 35 degrees to the
right or left of the head.
Monitors should also not be placed
too high or too low as this contributes to awkward posture which
results to muscle fatigue.
Reduce Flicker
Monitor flickers refer to repeated changes in monitor light intensity. It is caused by several factors
including but not limited to voltage fluctuations. Reducing flicker minimizes eye strain and
headaches. ThinkVision monitors allow users to use high frequency display modes that can
effectively reduce flicker.
Low Blue Light
Concerns on blue light affecting eye health have risen over the years. Blue light have
wavelength between 300 nm to 500 nm. The monitors have a factory setting that reduces blue
light emissions. Users can enable low blue light mode on these monitors from the OSD
settings.

meet the requirements of Energy Star.
Energy Star is an energy saving program for consumer electronics led by the U.S.
government. It was launched in 1992 by EPA and DOE to reduce energy consumption and
greenhouse gas emissions. Energy Star logo is a symbol of energy conservation and
environmental protection. It improves the concept of energy efficiency of consumers and
manufacturers, and effectively guides the market.
The regulation of Energy Star improves energy efficiency and reduces air pollution by
using more energy-efficient equipment in homes, offices and factories. One way to achieve
this goal is to use management to reduce energy consumption when products are not in
use.
The default settings for monitors conform to Energy Star certification. Any changes
by
users for more features and functionalities may increase power consumption, which will
exceed the limitation of Energy Star’s standard. If the user changes the options related to
energy efficiency when using, such as brightness, color mode, etc., select
All Reset Factory
or choose the Energy Star option, the power
consumption will be restored to the energy
efficiency with Energy Star standard.
For more information, please refer to (www.energystar.gov/products). All products of
Energy Star will be posted online and can be
accessed directly by governments, public
institutions and consumers.
