Desk Mount for Screens up to 46 Inches

The Ergotron LX HD arm supports displays weighing 14 to 30 lbs and measuring up to 46 inches. It attaches to a desk using either a clamp or a grommet base, freeing the work surface from a fixed stand. The arm suits users who alternate between sitting and standing while they work.

Sit-Stand Motion with 20-Inch Height Range

A 20-inch vertical lift lets the monitor move with the user’s posture without tools. The arm extends up to 33 inches and folds back to 4.5 inches from the desk rear, reclaiming depth in tight layouts. Integrated cable clips route cords along the aluminium structure.

Sustained Adjustment via Patented CF Motion

Patented CF motion technology holds the screen steady at any point within the 80-degree tilt, 360-degree pan and 90-degree rotation range. Locking connections between arm, extension and base prevent drift during daily height changes. The 17.50-lb aluminium build resists fatigue under continuous repositioning.

Questions about this item

How much weight can the arm support before it starts to sag under sustained use?

The arm is rated for monitors weighing 14 to 30 lbs, so it will hold steady within that range.

Does the arm generate any noise or heat when adjusted repeatedly throughout the day?

The mechanism uses passive CF motion technology with no motors or fans, so it runs silently and produces no heat.

What mounting hardware must already be on the desk for this arm to install?

You need either a desk edge up to 2.4" thick for the clamp base or a 12 mm grommet hole for the through-desk mount.
