What is the best configuration for a three-monitor setup using arms?

A three-monitor setup is most commonly configured as: a center primary monitor flanked by two secondary monitors at a slight angle (15°–30° inward). This is achieved with: a triple monitor arm (one arm with three VESA plates at adjustable angles); or a combination of a dual arm for the left and center monitors and a single arm for the right monitor (or vice versa). A center monitor that is landscape and two flanking monitors in portrait orientation is popular for developers and financial analysts. Ensure the desk is at least 60" wide to accommodate three 24"–27" monitors without overlap.
