Manufacturer description
The Ergotron HX HD Premium Heavy Duty Gaming Monitor Arm is built for the screens most arms buckle under: single displays up to 49 inches and 28 to 42 pounds, including 1000R curved ultrawides like the Samsung Odyssey G9. The HD pivot and extension give you 11.5 inches of lift, raising your screen 17.8 inches off the worksurface, with 360 degrees of rotation and 20 degrees of tilt so you can dial in the exact viewing angle for a long session. Mounting is covered either way: a two-piece desk clamp handles surface edges from 0.4 to 2.6 inches thick, and a grommet mount goes through a desk…
