Mount an additional monitor to your LX Arm or Tall Pole with the polished aluminum Ergotron LX Extension Arm Kit . It supports displays up to 40" weighing 7 to 25 lb with 75 x 75 and 100 x 100mm VESA patterns, allowing compatibility with most monitors. It provides -70 to 5° of tilt and 360° of rotation, swivel, pivot, and roll adjustments, as well as up to 13" of height adjustment and up to 24" of arm extension, allowing you to position your monitor wherever you'd like within 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 $234.
Monitor mounts have zero ongoing costs. Once installed and tensioned correctly, they operate for years with no maintenance.
