The Ergotron LX Dual Desk Mount Stacking Arm is a polished aluminum monitor mount designed to securely hold two displays on your desk. It accommodates monitors up to 40 inches with 75 x 75 or 100 x 100mm VESA patterns, weighing between 7 and 20 pounds each. This mount utilizes Constant Force lift-and-pivot motion technology, allowing for easy adjustment of your displays with up to 13 inches of lift, 75 degrees of tilt, and 360 degrees of pan and rotation for optimal viewing comfort.
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 $540.
Monitor mounts have zero ongoing costs. Once installed and tensioned correctly, they operate for years with no maintenance.
