What this arm holds

The Ergotron HX Desk Monitor Arm supports displays up to 42 inches and weighing 20 to 42 lb. It mounts to 75 x 75 mm through 200 x 200 mm VESA patterns. The polished aluminum finish suits professional workspaces.

Who should choose it and who should not

This arm suits users who need full articulation for a single heavy monitor on a desk up to 2.59 inches thick or a grommet up to 2.25 inches thick. It is not for buyers who want to mount multiple screens, need a wall-mount solution, or have displays outside the supported weight and size range.

How it fits your build

The clamp and grommet hardware are included, so no extra mounting kit is required. Up to 11.5 inches of height adjustment and -5 to 70 degrees of tilt free up desk space and enable ergonomic positioning. The arm pivots for landscape or portrait orientation.

Questions about this item

What desk thickness can the clamp handle for the Ergotron HX arm?

The clamp fits desks from .4 inches to 2.59 inches thick, so measure your top before ordering.

Will my older 75 x 75 mm VESA monitor attach to this arm?

Yes, the arm accepts patterns from 75 x 75 mm up to 200 x 200 mm, covering that older standard.

How do I confirm the arm holds its position once I mount a 20 lb screen?

Set the monitor at the desired height and angle; if it stays put without drifting, the internal spring tension is correctly balanced for that weight.
