Our take on the Ergotron LX Dual Monitor Arm White

The Ergotron LX Dual is a desk-mounted arm that holds two monitors side by side on independent arms. Each arm lifts, tilts, swivels and rotates to portrait, with a stated capacity of 20 kg (44.1 lb) split across the two mounts. It suits people who want their screens off the desk and at eye level, and it is sturdier than most budget dual arms. Owners rate it highly for build quality and smooth movement; the main complaints are the clamp footprint and the effort of setting tension.

Questions and answers

Can it hold two 27-inch monitors?
Yes, if the combined weight of both screens and mounts stays within the 20 kg (44.1 lb) limit. Check each monitor's weight with its stand removed.
Does it work on a glass desk?
Only if the glass is thick and rated for a clamp load. Ergotron also sells a grommet mount for desks with a drilled hole.
Can one screen be portrait and the other landscape?
Yes. Each arm rotates independently, so you can mix orientations.
How much desk depth does it need?
Leave room behind the desk for the arms to fold back. A wall or shelf close behind limits how far the screens can swing.
Is it better than a single dual-monitor stand?
It offers far more positioning freedom and frees the desk surface, but it costs more and takes more setup.
What is in the box?
Two arms, a desk clamp, VESA mounting plates and cable clips. VESA adapters for non-standard hole patterns may be needed separately.
