When should I get a dual monitor arm instead of two single arms?

A single arm holds one display on one adjustable bracket. A dual arm holds two displays — either on two independent arms from one base, or on a horizontal crossbar with two mount points. The dual arm advantage: it frees up the desk from two monitor stands, keeps both screens at a consistent height, and lets you adjust each independently. For any side-by-side dual monitor setup, a dual arm is cleaner and more practical than two singles. FindOfficeFurniture.com carries both — call 888-719-4960 to match the setup to your monitor sizes.
