  • Our take on the Ergotron LX Dual Side-by-Side Arm

    The Ergotron LX Dual Side-by-Side Arm mounts two monitors up to 27 inches each on one desk or wall base, with full-motion arms that lift, tilt, swivel and rotate to portrait. It carries up to 39.9 lb total and uses Ergotron's constant-force spring, so each screen holds its position without knobs to retighten. It suits people who want two screens at eye level without a fixed dual stand eating desk space. Against cheaper dual arms it is heavier built and easier to adjust one-handed; against Ergotron's taller HX line it has less reach and a lower weight ceiling.

    Pros
    • Constant-force spring holds each arm in place with little effort
    • Independent arms let each screen sit at its own height and angle
    • VESA compatible with most 75 mm and 100 mm monitors
    • Desk clamp and grommet mount included; wall mount option
    • Built to Ergotron's sturdier standard than budget dual arms
    Cons
    • 27-inch screen limit rules out larger monitors
    • 39.9 lb total capacity is shared across both arms
    • Needs a solid desk edge or wall stud for safe mounting
    • Cable routing is basic compared with premium arms
    • Assembly and tension tuning take time

    Questions and answers

    Will it hold two 27-inch monitors?
    Yes, if the two monitors together stay within 39.9 lb and each is VESA compatible. Check each monitor's weight with its stand removed before mounting.
    Can I mount it on a wall instead of a desk?
    Yes. It supports desk clamp, grommet and wall mounting, so you can choose based on your desk and stud placement.
    Does each arm move independently?
    Yes. The two arms are separate, so each screen can be set at its own height, distance and angle, including portrait rotation.
    Is it worth it over a fixed dual monitor stand?
    If you adjust your screens often or want them off the desk, the full-motion arms justify the step up. A fixed stand is simpler and cheaper if you set screens once.
    What's in the box?
    The arm assembly, VESA mounting plates, desk clamp and grommet hardware, and cable clips. A wall mount bracket is sold separately.
    How does it compare with the Ergotron HX?
    The HX is built for heavier, larger monitors with more reach. The LX Dual is lighter duty and better suited to two standard office monitors.
    Where is the Ergotron LX Dual Side-by-Side Arm cheapest?
    At Amazon, for $324.99, 33% under what the other stores charge, as of our latest check.
    Where can I buy the Ergotron LX Dual Side-by-Side Arm?
    13 stores we checked sell it, including Connection, colamco.com, Ergotron, CDW, ErgoDirect.com.
