Troubleshooting
Common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor sags or does not hold position. | Tension adjustment is too loose for monitor weight. | Adjust the tension screw on the arm using the appropriate hex key until the monitor holds its position. Refer to the product's quick start guide for specific tension adjustment points. |
| Arm movement is too stiff. | Tension adjustment is too tight. | Loosen the tension screw slightly until movement is smooth. |
| Monitors are not level. | Minor misalignment during installation or adjustment. | Adjust the tilt and rotation mechanisms on the VESA plate to fine-tune monitor alignment. |
| Desk clamp feels unstable. | Clamp not tightened sufficiently or desk thickness incompatible. | Ensure the desk clamp is fully tightened. Verify your desk thickness is within the specified range (0.47-1.25 inches). |
