Save Your Neck & Eyes
The Crestview Align Dual Monitor Arm enables monitors to be ergonomically positioned for increased comfort and productivity while working. Adjust the height, tilt, distance, and alignment of screens to reduce stress on the neck, shoulders, and torso—and to keep eyes from straining to see a monitor that is too far away.
Distance: Place your monitor screen roughly an arm's length (fingertip reach) away. Positioning the screen too far away will cause you to have trouble seeing the monitor and your eyes will pull your head forward causing you to extend your neck; this often leads to neck, back, and shoulder discomfort.
Height: Make sure that the top line of your monitor is at or just below eye level. Tilting your head backward to read your screen leads to discomfort.
Vertical Angle: Adjust the vertical screen angle to minimize glare from windows and other light sources.
Horizontal Angle: For the monitors that are positioned not directly in front of you, adjust the horizontal angle so that they're more perpendicular to your perspective and less parallel to your desk.
