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: 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 comer, or placing the keyboard in an adjustable
drawer to create a deeper working surface.
1.5 times of screen diagonal
● 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.

Chapter 2. 2-2
Quick tips for healthy work habits
The following information is a summary of some important factors to consider to help you remain
comfortable and productive while you use your computer.
Good posture starts with equipment setup: The layout of your work area and the setup of your
computer equipment have a large effect on your posture while using your computer. Be sure to
optimize the position and orientation of your equipment by following the tips outlined in
“Arranging your work area” on page 2-1 so you can maintain a comfortable and productive posture.
Also, be sure to use the adjustment capabilities of your computer components and office furniture to
best suit your preferences now and as your preferences change over time.
Minor changes in posture can help avoid discomfort: The longer you sit and work with your
computer, the more important it is to observe your working posture. Avoid assuming any one
posture for an extended period of time. Periodically make minor modifications in your posture to
help deter any discomforts that might arise. Make use of any adjustments that your office furniture
or equipment provide to accommodate changes in posture.
Short, periodic breaks help ensure healthy computing: Because computing is primarily a static
activity, it is particularly important to take short breaks from your work. Periodically, stand up from
your work area, stretch, walk for a drink of water, or otherwise take a short break from using your
computer. A short break from work gives your body a welcome change in posture and helps to
ensure you remain comfortable and productive while you do work.
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.

Chapter 2. 2-3
●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.
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.

Chapter 2. 2-4
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).

Chapter 2. 2-5
●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.
1. Press to open the main OSD menu.
