HX Arm for 42-Inch Displays

The Ergotron HX desk monitor arm supports screens up to 42 inches and mounts to a VESA 100 x 100mm pattern. It provides 75-degree tilt, pan and rotation so the display can be positioned for comfortable viewing. The bright white finish suits light-coloured workspaces. It is sold as a single unit.

Upgrade from Fixed Stands

A fixed stand locks the screen at one height and angle, forcing the user to adapt posture to the hardware. The HX arm replaces that limitation with full motion — extension, retraction and height adjustment — so the display moves to the user. The change is worth it when neck strain, desk clutter or shared workstations make a static position impractical.

Build Integration and Clearance

The arm clamps or bolts to the desk and lifts the monitor off the surface, freeing the footprint for documents, peripherals or a second screen. Its post design keeps the range of motion close to the mounting point, reducing the depth needed behind the display. Compatibility requires a VESA 100 x 100mm pattern on the monitor and a desk thick enough for the supplied clamp or grommet hardware.

Questions about this item

What desk thickness and mounting style does the HX 45-475-216 arm require?

The HX arm uses a post design that clamps to the desk edge or bolts through a grommet hole; both hardware sets are included for desks up to typical commercial thickness.

Which step do installers most often skip when fitting the HX arm to a VESA 100 x 100 mm monitor?

Many forget to set the spring tension to match the screen weight before tightening the VESA plate, so the arm drifts instead of holding position.

What part of the HX arm is most likely to need attention after several years of daily height changes?

The gas-spring cylinder inside the post provides the 10-year limited warranty coverage; if lift force fades, the cylinder is the replaceable module.
