Finding your comfort zone
Find your comfort zone by adjusting the viewing angle of the monitor, using a
footrest, or raising your sitting height to achieve maximum comfort. Observe
the following tips:
• refrain from staying too long in one fixed posture
• avoid slouching forward and/or leaning backward
• stand up and walk around regularly to remove the strain on your leg
muscles
• take short rests to relax your neck and shoulders
• avoid tensing your muscles or shrugging your shoulders
• install the external display, keyboard and mouse properly and within
comfortable reach
• if you view your monitor more than your documents, place the display at
the center of your desk to minimize neck strain

Long viewing hours, wearing 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 sections provide suggestions on
