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
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 and viewing your monitor
Position and adjust your computer monitor for comfortable viewing by considering
the following items:
v 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.
v 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.
v Tilt: Adjust the tilt of your monitor to optimize the appearance of the screen
content and to accommodate your preferred head and neck posture.
v 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:
© Copyright Lenovo 2008.
2-1
v Use adequate lighting for the type of work you are performing.
v Use the monitor brightness, contrast, and image adjustment controls, if
equipped, to optimize the image on your screen to meet your visual preferences.
v 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.
v 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.
v 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
v 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.

Selecting a supported display mode
The display mode the monitor uses is controlled by the computer. Therefore, refer
to your computer documentation for details on how to change display modes.
The image size, position and shape might change when the display mode changes.
This is normal and the image can be readjusted using automatic image setup and
the image controls.
Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or
Flat Panel technology is inherently flicker-free.
Note: If your system has previously been used with a CRT monitor and is
currently configured to a display mode outside the range of this monitor, you may
need to re-attach the CRT monitor temporarily until you have re-configured the
system; preferably to 1280 x 1024 at 60 Hz, which is the Native Resolution Display
mode.

Understanding power management
Power management is invoked when the computer recognizes that you have not
used your mouse or keyboard for a user-definable period. There are several states
as described in the table below.
For optimal performance, switch off your monitor at the end of each working day,
or whenever you expect to leave it unused for long periods during the day.
