Maintenance
Regular maintenance ensures the longevity and safe operation of your monitor stand.
- Cleaning: Wipe the stand with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Check Tightness: Periodically check all screws and connections, especially the desk clamp/grommet and VESA plate screws, to ensure they remain tight.
- Gas Spring Tension: If monitors sag or do not hold their position, adjust the gas spring tension using the provided Allen key. Turn clockwise to increase tension for heavier monitors, and counter-clockwise to decrease tension for lighter monitors.
Troubleshooting
Here are solutions to common issues you might encounter:
- Monitor Sags or Won't Stay Up:
This indicates insufficient gas spring tension. Use the Allen key to turn the adjustment screw clockwise to increase tension. Test the arm's movement after small adjustments until the monitor holds its position. - Monitor is Difficult to Move Down:
The gas spring tension might be too high for your monitor's weight. Use the Allen key to turn the adjustment screw counter-clockwise to decrease tension. - Stand Wobbles:
Ensure the desk clamp or grommet mount is securely tightened to the desk. Check that the desk itself is stable and not prone to movement. The wider VESA plate and gap-free arm/post connection are designed to minimize wobbling. - Monitors Not Level:
Adjust the tilt and rotation mechanisms on the VESA plate to align your monitors. Ensure the VESA plates are securely attached to the monitors.
