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.
    Here are some additional tips for comfortable viewing of your display:

  • Use adequate lighting for the type of work you do.

  • Use display brightness, contrast, and image controls (if available) to optimize the image on the screen for your visual needs.

  • Keep the display screen clean so that you can see the content clearly.

Long periods of focused visual activity tend to strain the eyes. Be sure to periodically move away from the display screen and gaze at a distant object to relax your eye muscles. If you have any questions about eye strain or visual discomfort, consult vision care professional for advice.
Tips on Healthy Work Habits
The following is a summary of some important factors that are useful to keep you comfortable and productive while using your computer.

  • Good posture comes from equipment placement: The layout of your work area and the placement of your computer equipment can have a significant impact on your posture while using the computer. Be sure to follow the tips listed in ” Arrange Your Working Area” on pages 2-1 to optimize the placement and orientation of your equipment so you can maintain comfortable posture and efficiency. In addition, be sure to use the adjustment features of your computer components and office furniture to meet your needs, and adjust them over time as your needs  change.

  • Slight changes in posture help keep you comfortable: the longer you sit in front of a computer, the more important it becomes to pay attention to your work posture. Avoid maintaining one posture for long periods. Regular slight changes in posture can help prevent possible discomfort.
    Use the adjustment function provided by office furniture or equipment to adapt to changes in posture.

  • Regular short breaks help ensure healthy computing: Because computing is primarily a static activity, it is especially important to take short breaks during the workday. Take regular breaks to stand in front of your work area, stretch your limbs, walk around or have a drink, or otherwise taka short break from using the computer. Taking short breaks during work allows for changes in body posture that can help you stay comfortable and productive while working.

Low Blue Light
Concerns on blue light affecting eye health have risen over the years. Blue light have wavelength between 300 nm to 500 nm. The monitors under default setting modereduce blue light emissions. The monitors achieve the requirement of Low blue Light (Hardware Solution).
Select Supported Display Modes
The display mode used by the display is controlled by the computer. Therefore, you should refer to the computer’s documentation for detailed information on how to change the display mode.
When the display mode is changed, the image size, position, and shape may change. This is normal and the image can be readjusted using the automatic image settings and image controls.
Unlike CRT displays, which require high refresh rates to minimize flicker, LCD or flat panel technology is inherently flicker-free.
Note: If the system has previously been used in conjunction with a CRT display and is currently configured for a display mode outside the range of that display, you may need to temporarily reconnect the CRT display until the system has been reconfigured; it is best to set it to 1920×1080 (100Hz), the normal display mode.
The display modes shown below are factory optimized.
