It supports an upward tilt of 85°, a downward tilt of 25°, 360° rotation, and 90° swivel left and right. With a maximum height of 42cm and an extension of 47.5cm, you can easily raise your monitor to eye level, providing greater freedom in monitor placement and saving valuable desk space.

3.2 LockSteady Technology
Experience smooth, effortless movement with just one finger, combined with stable locking at any desired position. The LockSteady technology ensures that your monitor stays exactly where you leave it, preventing unwanted sagging or drifting. This feature is ideal for users who frequently adjust their monitor position, as well as those who prefer a fixed setup.

4. Maintenance and Adjustment
4.1 Tension Adjustment with Window
Unlike traditional monitor arms that rely on guesswork for tension adjustment, the HUANUO HNDMA118 features a tension strength indicator window. This allows you to visually confirm the current tension setting, making precise adjustments straightforward. This ensures your monitor is always held securely at the desired height.

4.2 Adjusting Tension Steps
- Push the upper arm horizontally downwards to check the tension.
- Rotate the adjustment screw towards '+' to increase tension or '-' to decrease tension, adjusting the monitor's height.

4.3 Addressing Monitor Sagging
If your monitor sags or does not hold its position, it indicates that the tension needs to be increased. Use the provided Allen wrench to turn the tension screw towards the '+' direction. This will increase the tension, allowing the arm to firmly support your monitor.

4.4 Cable Management
The monitor arm includes integrated cable clips to help organize and conceal cables, maintaining a tidy and professional workspace.
5. Troubleshooting
- Monitor Sags/Doesn't Hold Position: Increase the tension using the adjustment screw as described in Section 4.3. Ensure the monitor weight is within the 2-9kg range.
- Arm is Too Stiff/Hard to Move: Decrease the tension using the adjustment screw. Ensure the monitor is properly mounted, as the arm's movement may feel stiff without the monitor's weight.
- Monitor Wobbles: Ensure all mounting screws (VESA plate, clamp/grommet base) are securely tightened. Check that the desk surface is stable.
- Installation Issues: Refer to the detailed Japanese instruction manual included with the product. Verify desk thickness and VESA compatibility.
