Heavy-duty arm for ultrawide screens

The Ergotron HX single monitor arm supports displays up to 49 inches and 20 to 42 pounds. It provides 23.6 inches of extension and 11.5 inches of lift for flexible positioning. Up to 360-degree rotation and 75-degree tilt allow precise screen alignment. The arm is 10,000-cycle tested for long-term durability.

Polished aluminium with desk clamp and grommet

The mount includes two attachment methods: a desk clamp for edges up to 0.42 inches thick and a grommet mount. Integrated cable management keeps wires tidy along the arm. A streamlined profile frees desk space for other items. Professional-grade construction is backed by a ten-year warranty.

Check VESA pattern and display depth

Verify your monitor uses a compatible VESA pattern and weighs within the 20 to 42 pound range. Ensure the display depth is less than six inches for proper fit. Samsung 49-inch Odyssey G9 owners must add the HX Heavy-Duty Tilt Pivot accessory or choose the bundled solution. Confirm desk thickness suits the clamp or grommet installation.
