Chapter 2. Adjusting and Using the Display

This section describes how to adjust and use this display.

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.

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.

For comfortable viewing of the display, the following factors should be considered

when placing and adjusting computer displays:

Chapter 2. Adjusting and Using the Display 2-1

 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.
