The Ergotron HX is a heavy-duty desk clamp arm that carries two large monitors side by side. Its Constant Force hinge lets you move each screen with a fingertip and keeps it where you leave it, and the hinged center bow lets you swing both screens toward a colleague for screen sharing. It is built for 32-inch and heavier panels, so it costs more and takes more desk edge than lighter dual arms from Ergotron's LX line or budget brands. Owners rate the build and smooth movement highly; the main complaints are setup effort and the desk space the clamp and base need.

Owners and reviewers treat the HX as a premium dual arm that does its job for years. They praise the smooth Constant Force movement and the screen-sharing hinge, and most criticism lands on installation and the space the mount takes.
The Ergotron HX Desk Mount Dual Monitor Arm holds two monitors up to 32 inches on a single desk-mounted arm. It has a matte black finish.
Constant Force Technology makes it easy to reposition the monitors. A hinged bow lets you pan the monitors, which helps when sharing your screen with others.
