How to install a monitor arm

A monitor arm clamps to the edge of a desk or through a grommet hole and holds the screen by its VESA mounting holes. The two things to get right are the clamp on a solid desk edge and the spring tension set to the screen's weight.

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Desk clamp or grommet mount
  • Pole and arm sections
  • VESA plate
  • Monitor screws of the right size and spacers
  • Cable clips

Step by step

  1. Step 1: Check the monitor's weight and VESA hole pattern against the arm's specification.

  2. Step 2: Fit the clamp to a solid part of the desk, away from thin edges or glass, and tighten it firmly with a protective pad underneath.

  3. Step 3: Slide the pole and the arm onto the clamp.

  4. Step 4: Screw the VESA plate to the back of the monitor, using spacers if the back of the screen is curved or recessed.

  5. Step 5: With the arm in its lowest position, hook or slide the monitor onto the arm and lock it.

  6. Step 6: Adjust the spring tension until the screen stays where you put it, then route the cables through the clips.

Common mistakes

  • Clamping to a thin or hollow desktop, which bends or cracks it.
  • Using screws that are too long, which can damage the monitor.
  • Adjusting spring tension with no monitor fitted, so the arm snaps up.

Safety notes

  • Gas-spring arms can move quickly when unloaded; keep the arm in its lowest position while fitting or removing the screen.
  • Stay within the arm's weight rating.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
