What monitors are compatible with the Ergotron LX Desk Monitor Arm?
The LX is designed for one flat, curved, or ultrawide monitor up to 34 inches diagonal and weighing 7 to 25 pounds. The display must use a VESA 75 x 75 mm or 100 x 100 mm mounting pattern.
What desk thicknesses can the LX clamp or grommet mount accommodate?
The included two-piece desk clamp fits work surfaces from 0.4 to 2.4 inches thick. The included grommet mount passes through a surface hole and fits desks up to 2.25 inches thick, so check both the thickness and available hole clearance before installation.
How much height and movement adjustment does the LX provide?
The arm provides 13 inches of lift and can raise the monitor up to 17.3 inches above the work surface, depending on the setup. It also provides 360-degree rotation and up to 75 degrees of tilt for positioning the screen.
What durability testing and warranty does the LX Desk Monitor Arm have?
Ergotron states that the LX passes a 10,000-cycle motion test and includes a 10-year warranty. These are manufacturer-stated durability and coverage terms; retain the purchase documentation and consult Ergotron for the warranty's applicable conditions.
Does the LX include cable management?
Yes. The LX's design includes built-in cable management to help route monitor cables along the arm and keep the workspace more orderly. The arm is sold as a single-monitor mount, so cable routing should be planned around that configuration.
