Preface
Lighting
Proper lighting and comfortable display viewing angle can reduce eye strain and muscle fatigue in your neck and
shoulders.
• Position the display to avoid glare or reflections from overhead lighting or outside sources of light.
• Keep the display screen clean and set the brightness and contrast to levels that allow you to see the screen clearly.
• Position the display directly in front of you at a comfortable viewing distance.
• Adjust the display-viewing angle to find the best position.
