9. Troubleshooting
If you encounter issues with your MOUNTUP Triple Monitor Mount, please refer to the following common solutions:
- Monitor Sags or Won't Stay Up: Adjust the gas spring tension. Turn the screw counter-clockwise ('+') to increase tension for heavier monitors. Ensure the monitor weight is within the specified range (4.4-19.8 lbs per arm).
- Monitor Floats Up or Won't Stay Down: Adjust the gas spring tension. Turn the screw clockwise ('-') to reduce tension for lighter monitors.
- Monitors Are Not Level: Check that the VESA plates are securely attached and that the arms are properly aligned on the pole. Minor adjustments can be made by slightly loosening and re-tightening the VESA plate screws or arm clamps.
- Mount Feels Unstable: Ensure the C-clamp or grommet mount is tightened securely to the desk. If using a C-clamp on a thin table, consider using a reinforcement plate (not included) to prevent damage and improve stability.
- Difficulty Adjusting Movement: Check all pivot points and ensure they are not overtightened. Lubrication may be applied to moving parts if necessary, following manufacturer guidelines.
