Even a well-installed monitor arm can develop issues. Here is how to diagnose and fix the most common problems.

Monitor Sinks Down Slowly

This usually means the gas spring tension is too low. Use the hex key that came with the arm to tighten the tension screw clockwise. Keep adjusting until the monitor stays at the height you set. If the tension screw is maxed out and the monitor still sinks, the gas spring may need replacement.

Clamp Leaves Marks

Tightening the clamp too hard can dent or scratch your desk. Always use the protective pads between the clamp and the desk surface. If the included pads are thin, add felt furniture pads for extra cushioning. For existing marks, a damp cloth followed by a furniture repair marker can help.

Arm Is Stiff

If the joints are hard to move, loosen the tension screw counterclockwise. If it is still stiff after that, dirt may have accumulated in the joints. Blow compressed air into the joint gaps and apply a small amount of silicone lubricant.

Monitor Is Not Level

A tilted screen is usually caused by an uneven VESA plate attachment. Remove the plate, check it with a level, and reattach it. Some arms have a tilt adjustment at the joint — use that to fine-tune the angle.

Desk Wobbles

If your whole desk shakes when you move the arm, try repositioning the clamp closer to the desk frame where the surface is more rigid. If the desk itself is unstable, add stabilizing brackets to the legs.

Most monitor arm problems have simple fixes. Address them promptly to keep your setup safe and comfortable.
