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 center 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.
