Can I stack two monitors vertically on a monitor arm?

Vertical stacking (one monitor directly above another) is possible with specialized dual-monitor stacking arms designed for this configuration. A stacking arm has two VESA plates — one at the end of the arm and one on a secondary plate above it — both connected to a single pole or clamp. This configuration is popular with software developers, financial analysts, and content creators who need a primary horizontal monitor and a secondary reference screen above it. Ensure the combined weight of both monitors is within the arm's weight rating. OfficeFurniture2go.com can advise on stacking monitor arm configurations — call 1-800-460-0858.
