Adjusting and using your monitor
This section will give you information on adjusting and using your monitor.
Comfort and accessibility
Arranging your work area
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.
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.
