HX Ultrawide Monitor Arm 28-42 lbs

The Ergotron HX Ultrawide Monitor Arm is a desk mount designed for ultra-wide and curved screens weighing between 28 and 42 pounds. It targets professionals and gamers who need to reposition large displays frequently for immersive viewing or ergonomic comfort while reclaiming desk space occupied by bulky stock stands.

Desk integration and mounting flexibility

The arm includes both a desk clamp and a grommet mount base for secure attachment to various work surfaces. It supports VESA 75 and 100 millimeter patterns via an included plate and uses a heavy-duty tilt pivot to handle the depth of curved monitors measuring 6 to 12 inches deep. The extension arm provides 11.5 inches of height adjustment to suit sitting or standing positions.

Sustained load stability and durability

Built for continuous heavy-duty use, the arm maintains stable positioning across its full range of motion without drifting under the maximum 42-pound load. The professional-grade construction is backed by a 10-year warranty, ensuring the tilt pivot and lift mechanism retain consistent tension and smooth articulation through years of daily adjustments.
