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://

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.

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

Selecting a supported display mode

Addressability

Refresh rate

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 re­attach the CRT monitor temporarily until you have re-configured the system;
preferably to at 60 Hz, which is the Native Resolution Display mode.

The display modes shown below have been optimized at the factory.

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.
