- Screen Installation: Slide the monitors onto the arm heads. Ensure they are securely locked in place.
Adjustments
Once installed, you can fine-tune the monitor position:


- Tension Adjustment: Use the provided tool to adjust the tension of the arm. This ensures the monitor stays at the desired height.
- Tilt Adjustment: Use the screw at the back of the VESA plate to adjust the tilt angle of the monitor.
- Rotate Adjustment: You can rotate the monitor for portrait or landscape orientation. Warning: Do not fully loosen the screw at the top of the rotation joint to prevent the monitor from falling off.
Cable Management
To keep your workspace tidy, route the monitor cables through the plastic clips located on the arms. Ensure there is enough slack in the cables to allow for full range of motion without pulling on the connectors.
