Special notes on LCD monitors

The following are normal characteristics of LCD monitors and do not indicate a problem:

• Screen flicker during initial use due to the nature of fluorescent lighting. Turning the power switch off and on again should resolve this.
• Slightly uneven brightness on the screen, depending on the desktop pattern used.
• The LCD screen has 99.99% or more effective pixels. It may include blemishes of 0.01% or less, such as a missing pixel or a pixel that is always lit.
• An afterimage of a previous screen may remain after switching images, or when the same image is displayed for hours. The screen can be recovered slowly by changing the image or turning off the power switch for a few hours.

Tips and information for comfortable use

Computer users may complain of eyestrain and headaches after prolonged use. Users are also at risk of physical injury after long hours of working in front of a computer. Long work periods, bad posture, poor work habits, stress, inadequate working conditions, personal health, and other factors greatly increase the risk of physical injury.

Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis, or other musculoskeletal disorders. Symptoms may appear in the hands, wrists, arms, shoulders, neck, or back, including numbness, burning or tingling sensations, aching, soreness, tenderness, pain, swelling, throbbing, stiffness, tightness, coldness, or weakness.

If you experience these symptoms, or any other recurring or persistent discomfort and/or pain related to computer use, consult a physician immediately and inform your company's health and safety department.

The following section provides tips for more comfortable computer use.

Finding your comfort zone

Adjust the viewing angle of the monitor, use a footrest, or raise your sitting height to achieve maximum comfort.

• Refrain from staying too long in one fixed posture.
• Avoid slouching forward and/or leaning backward.
• Stand up and walk around regularly to remove strain on your leg muscles.

Taking care of your vision

Long viewing hours, incorrect glasses or contact lenses, glare, excessive room lighting, poorly focused screens, very small typefaces, and low-contrast displays could stress your eyes. The following suggestions may help reduce eyestrain:

• Rest your eyes frequently.
• Give your eyes regular breaks by looking away from the monitor and focusing on a distant point.
• Blink frequently to keep your eyes from drying out.

Display Adjustments:

• Keep your display clean.
• Position your head higher than the top edge of the display so your eyes point downward when looking at the middle of the display.
• Adjust display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity.
• Eliminate glare and reflections by:
  • Positioning your display so its side faces a window or light source.
  • Minimizing room light using drapes, shades, or blinds.
  • Using a task light.
  • Changing the display's viewing angle.
  • Using a glare-reduction filter.
  • Using a display visor (e.g., a piece of cardboard extended from the display's top front edge).
• Avoid adjusting your display to an awkward viewing angle.
• Avoid looking at bright light sources, such as open windows, for extended periods.

Developing good work habits

• Take short breaks regularly and often.
• Perform some stretching exercises.
• Breathe fresh air as often as possible.
• Exercise regularly and maintain a healthy body.
