Chapter 2. 2-1
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. For more detailed
information on any of these topics, visit the Healthy Computing Web site at: http://www.
lenovo.com/healthycomputing/.
Arranging your work area
Use a work surface of appropriate height and available working area to allow you to work in
comfort.
Organize your 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 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
510 mm to 760 mm (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 state.
• 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 reections on the screen from
overhead lighting or nearby windows.

Chapter 2. 2-2
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 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.
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 ofce 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
modications in your posture to help deter any discomforts that might arise. Make use
of any adjustments that your ofce 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.
