Two Ergotron LX Pro arms on one pole, each for a screen of 1.8 to 9 kg and up to 27 inches (18.1 kg in total). Constant Force lift through 33 cm per screen, 85 degrees of tilt, a two-piece clamp for desks 10 to 60 mm, and Ergotron's 10-year warranty.
Ergotron LX Pro Dual Side-by-Side
Two Arms, Each Doing Its Own Job
The LX Pro Dual Side-by-Side puts two full LX Pro arms on one pole, joined by a T-bracket. Each carries a screen of 1.8 to 9 kg and up to 27 inches, with 33 cm of lift and its own extension, so the screens can sit edge to edge or at different heights and depths.
Ergotron rates the pair at 18.1 kg in total.
Movement
Light to Move, Stays Put
Ergotron's Constant Force™ lift balances each screen on a spring, so moving it takes the same small effort through the whole range. Each screen tilts 85° (70° up, 15° down), pans 180° and rotates 360° for portrait work.
The base pans 360°, or 180° with the rotation stop engaged, which keeps the arms off a wall or partition.

Figures are from Ergotron's LX Pro specification sheets and dimension drawings (2025–2026). Where Ergotron's sheets differ between editions, the lower figure is shown. Weigh your screen without its stand. Ergotron's February 2026 dual sheet gives 65.6 cm of extension against 64 cm on the 2025 sheet.
Who It Suits
Two Screens, Each Set on Its Own
Because each screen has a full arm and extension, one can sit closer for reading while the other stays back, or one can turn to portrait for documents and code. It suits two monitors of up to 27 inches each, 18.1 kg between them.
Send us both screen models on 02 9640 0642 and we will check the weights and your desk before you order. The photo shows the white finish.

Frequently Asked Questions
If each screen weighs 1.8 to 9 kg without its stand, is 27 inches or smaller and has 75 or 100 mm VESA holes, it is within Ergotron's rating. Check the weights on the screen maker's specification sheet.
The two-piece clamp takes desks 10 to 60 mm thick and needs a clear back edge. For a grommet hole, Ergotron's grommet mount (98-728) is sold separately; call 02 9640 0642 and we will add it.
Side-by-side puts the screens next to each other, the usual set-up for two 24 to 27-inch screens. The LX Pro Dual Stacking Arm has a taller 30.4 cm pole to put one screen above the other, which saves desk width.
The LX Pro Dual gives each screen its own arm, up to 27 inches and 9 kg each. The HX Dual puts both screens on one heavy-duty arm with a hinged bow and handle and takes 32-inch screens, at a higher price.
10 years. Ergotron's warranty terms give a 10-year warranty on LX monitor arms, and the product's specification sheet states 10 years.
