The Ergotron LX Dual Desk Mount Stacking Arm in Matte Black is a robust monitor mount designed to elevate two displays up to 40 inches each, weighing up to 20 lbs per screen. Constructed from durable steel and aluminum, this mount offers extensive adjustability including 360° rotation and swivel, 75° tilt, and 13 inches of height adjustment, allowing for both landscape and portrait orientation. It securely attaches to desks via a clamp (0.5 to 2.6 inches) or grommet mount (0.5 to 2.5 inches width, 0.78 to 2.25 inches depth), providing an ergonomic and space-saving solution for your workspace.
Match the mount's weight capacity to your monitor; too heavy and it droops, too light and it shoots upward. Gas spring arms offer easy adjustment, while pole mounts are cheaper and static. Available from $529.
Monitor mounts have zero ongoing costs. Once installed and tensioned correctly, they operate for years with no maintenance.
