Before Use
Furniture and posture – Sit in a chair with good back support and armrests. Adjust the level of the chair so your feet are
flat on the floor. A footrest may make you more comfortable. Sit with relaxed, upright posture — avoid slouching forward
or leaning far backward.
Viewing angle of the display – Position the display 18 to 26 inches directly in front of you, with the top of the screen at
or a little below eye level. Use the display's tilting feature to find the best position. You can reduce eye strain and muscle
fatigue by placing the display in the proper position.
Lighting – Choose a location where windows and lights do not create glare and reflection on the display. Use indirect
lighting to avoid bright spots on the display. You can also purchase accessories for your display that help reduce glare.
Proper lighting adds to your comfort and work effectiveness.
