Give your peepers a breather! Reduce eyestrain by taking regular vision breaks. Try looking into the distance two or three times an hour for 30 seconds.

Offering easy adjustment of the monitor's height and depth up to 12 inches, the M4 is an ideal monitor arm solution for the multiple-user workstation. When a new user sits down, he or she can reposition the monitor at an ergonomic height and distance in a matter of seconds. And when the computer is not being used, the monitor pushes away easily to create extra real estate on the work surface.
