What is the difference between a single and dual monitor arm?

A single monitor arm holds one display on one adjustable arm. A dual monitor arm holds two displays — either on two independent arms from one base, or on a horizontal bar with two mounting points. Dual arms allow independent positioning of each monitor (different heights and angles). For side-by-side dual monitors, a dual arm keeps both displays at consistent heights and eliminates two monitor stands from the desk.
