How much weight can this mount hold?
This arm has a maximum load capacity of 22 lb (9979.03 g), with a minimum requirement of 4 lb. It accommodates a wide range of monitor weights, from lightweight LED panels to heavier professional displays with built-in speakers or additional hardware.
Is this monitor arm height adjustable?
Yes, the LX Pro features full height adjustment along its tall pole design. This allows users to raise or lower the monitor to match their eye level, which is essential for maintaining proper posture and reducing neck strain during long work sessions.

How does the grommet mount installation work?
The grommet mount involves drilling a hole in your desk (typically 1.5 to 3 inches in diameter) and securing the arm's base through it with included hardware. This provides a stable, permanent attachment that doesn't require clamping to the desk edge, ideal for thicker or reinforced work surfaces.
What adjustment ranges does this arm offer?
It provides 360° rotation, panning from 180° to 360°, and tilting from 15° to 70°. These ranges allow full positional flexibility—you can rotate the monitor for shared viewing, pan it side-to-side for multi-task alignment, and tilt it to reduce glare or match your sight line.
