Manufacturer description

The Ergotron HX Premium Heavy Duty Monitor Arm is built for the screens most arms cannot hold: single displays up to 49 inches diagonal weighing 20 to 42 pounds, including flat and slightly curved ultrawides. In the box you get the arm, extension, standard monitor pivot, and mounting hardware, with a two-piece desk clamp that grips edges from 0.4 to 2.6 inches thick and a grommet option for routing through a desk hole. VESA support covers 75x75mm, 100x100mm, 200x100mm, and 200x200mm patterns. The low-profile clamp tucks into tight spaces and integrated cable management keeps the run behind…

Frequently Asked Questions

Will this hold a 49-inch ultrawide monitor?

Yes, the HX supports single screens up to 49 inches diagonal. For the Samsung 49-inch Odyssey G9 specifically, Ergotron requires the separate HX Heavy Duty Tilt Pivot (98-540-216), or you can buy the bundled version that includes the HD Pivot in the box (45-647-224 or 45-647-216).

What monitor weight range does the HX support?

The arm is rated for 20 to 42 pounds. That is a minimum as well as a maximum, so very light monitors below 20 lbs are not a good match for this model.

Which VESA mounting patterns does it fit?

It fits 75x75mm, 100x100mm, 200x100mm, and 200x200mm VESA patterns out of the box. For larger patterns, Ergotron sells a VESA Bracket Adaptor Kit (97-759) separately.

Can I mount this through a grommet hole instead of clamping the desk edge?

Yes. The HX ships with both a two-piece desk clamp for edges 0.4 to 2.6 inches thick and a grommet mount for installing through a hole in the desk surface.

How much height and movement does it actually give me?

You get 11.5 inches of lift, with the screen able to rise 17.8 inches above your desktop, along with 360 degrees of rotation and 75 degrees of tilt.
