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
Step 1: Check the monitor's weight and VESA hole pattern against the arm's specification.
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.
Step 3: Slide the pole and the arm onto the clamp.
Step 4: Screw the VESA plate to the back of the monitor, using spacers if the back of the screen is curved or recessed.
Step 5: With the arm in its lowest position, hook or slide the monitor onto the arm and lock it.
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.
