Chapter 2. Adjusting and Using the Display
This section describes how to adjust and use this display.
Comfort and Assistance Functions
Good ergonomic designs are important for the comfortable use of your personal computer. Your
workplace and the equipment you use should be arranged appropriately for your personal needs and the
type of work you do. In addition, healthy work habits can help you achieve optimal efficiency and comfort
when using a computer.
Arrange Your Working Area
Use a work surface of the right height and enough work area so that you can work comfortably.
Arrange your work area according to the way you use materials and equipment. Keep frequently used
materials neatly organized in your work area, and place frequently used items (such as a computer mouse
or telephone) in an easily accessible location. The placement and setup of equipment are very important
to your work posture. The following topics describe how to optimize equipment settings to achieve and
maintain a good working posture.
Placing and Viewing the Display
For comfortable viewing of the display, the following factors should be considered when placing and
adjusting computer displays:
• Viewing Distance: The recommended viewing distance between your eyes and the display screen
is 1.5X the screen diagonal. Solutions to meet this required distance in a small office include:
keeping the desk a certain distance from the wall or partition to allow space for the display, using a
flat panel or smaller display and keeping the display in the corner of the desk, or placing the
keyboard in an adjustable drawer board to create a deeper work surface.
• Display Height: If your display is not height-adjustable, place your head and neck in a natural,
comfortable (vertical or upright) position. If your display is not height-adjustable, you can place a
book or other sturdy object under the base of the display to achieve the desired height. The general
rule is to sit comfortably with the top of the display screen at eye level or slightly lower. However,
it is important to optimize the height of the display so that the relative position between the eyes
and the center of the display provides the right visual distance and a comfortable viewing
experience when the eye muscles are relaxed.
• Tilt: Adjusting the tilt of your display optimizes the appearance of your screen content and keeps
your head and neck in the best possible position.
• Regular Location: Place the display in such a way that overhead lighting or nearby windows do
not cause glare or reflection on the screen.
