You get 11.5 inches of lift, a screen height reaching 17.8 inches above the desktop, 360 degrees of rotation, and 75 degrees of tilt, so you can drop the panel for focused work or raise and swivel it to share a spreadsheet with someone standing beside you.

Frequently Asked Questions
Will this hold my 49-inch ultrawide monitor?
Yes, for flat or slightly curved ultrawides up to 49 inches and 20 to 42 pounds. Note that the Samsung 49-inch Odyssey G9 specifically requires the separate HX Heavy Duty Tilt Pivot accessory (98-540-216), or you can buy the bundled 45-647-224 or 45-647-216 kit that includes the HD Pivot in the box.
What VESA sizes does the Ergotron HX support?
It fits 75x75mm, 100x100mm, 200x100mm, and 200x200mm patterns directly. For larger patterns, Ergotron sells a separate VESA Bracket Adaptor Kit (97-759).
Can I mount it without drilling into my desk?
Yes. The included two-piece desk clamp works on surface edges 0.4 to 2.6 inches thick with no drilling. A grommet mount is also included if you prefer to install through an existing hole in the desk.
How high does the monitor go and how much does it move?
The arm gives 11.5 inches of lift, raising the screen up to 17.8 inches above the desktop, with 360 degrees of rotation and 75 degrees of tilt for repositioning throughout the day.
Can I add a second or third monitor later?
Yes. Ergotron offers an optional dual monitor kit (97-783) and a triple monitor kit (98-009-026) to expand the workstation. These are sold separately and are not included with the single-monitor HX arm.
