Which displays can the HX Desk Monitor Arm support?
The HX is intended for one flat or slightly curved ultrawide display up to 49 inches diagonal and weighing 20–42 lb. Check the target monitor’s actual weight and mounting pattern before installation.
What VESA mounting patterns are compatible?
The listing identifies 75×75, 100×100, 200×100, and 200×200 mm VESA patterns as compatible. Larger patterns require the separate 97-759 VESA Bracket Adaptor Kit, so confirm your display’s hole spacing and adapter need first.
How much can the monitor be repositioned?
The arm provides 11.5 inches of lift, raises the screen up to 17.8 inches above the desktop, rotates 360 degrees, and tilts 75 degrees. These figures describe the arm’s stated adjustment range.
What warranty and support are advertised?
The Amazon product page says Ergotron products carry a 10-year warranty and that expert technical support is available. Review the linked warranty terms for the exact coverage, exclusions, and process before relying on that statement.
Is the HX suitable for a curved ultrawide monitor?
The product listing identifies compatibility with flat or slightly curved ultrawide monitors. It does not establish compatibility with every curve radius or larger VESA pattern, so verify those details for the specific display before buying.
