Tilt and Swivel
Adjust the monitor's tilt and swivel to reduce glare and find the most comfortable viewing angle.
- The monitor can tilt up to 70 degrees upwards and 15 degrees downwards.
- Swivel the monitor left or right as needed.

The increased tilt range provides an extra 10 degrees of downward tilt for the perfect viewing angle.
Rotation
The arm allows for 360-degree rotation at the base and 360-degree rotation at the monitor pivot, enabling portrait or landscape viewing.
- Rotate the monitor to switch between landscape and portrait orientations.

Tension Adjustment
The arm's tension can be adjusted to accommodate monitors of different weights, ensuring smooth and stable movement. The new tension indicator simplifies this process.
- Locate the tension adjustment screw on the arm.
- Rotate clockwise for heavier displays to increase tension.
- Rotate counter-clockwise for lighter displays to decrease tension.
- Use the tension indicator to set the level once and repeat for quick installation of multiple workstations.

Troubleshooting
If you encounter issues with your monitor arm, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor arm sags or does not hold position. | Tension is too low for monitor weight. | Increase tension using the adjustment screw (rotate clockwise for heavier displays). Refer to 'Tension Adjustment' section. |
| Arm is too stiff to move. | Tension is too high for monitor weight. | Decrease tension using the adjustment screw (rotate counter-clockwise for lighter displays). Refer to 'Tension Adjustment' section. |
| Monitor wobbles at the pivot point. | Loose connection at the monitor pivot or VESA plate. | Ensure all VESA mounting screws are securely tightened. Check the pivot joint for any accessible tightening points as per the assembly guide. |
| Desk clamp feels unstable. | Clamp not tightened sufficiently or desk surface is too thin/thick. | Re-tighten the desk clamp. Ensure your desk thickness is within the 0.4 to 2.4 inch range. |
