4. Setup and Installation
Follow these steps to install your HUANUO HNSS8-E monitor arm.
Step 4.1: Choose Mounting Option
The monitor arm offers two installation methods: C-clamp or Grommet mount.
- C-Clamp Installation: Suitable for desks with edges. Attach the C-clamp base to the desk edge and tighten the knob until secure.
- Grommet Mount Installation: Requires a hole in the desk (diameter 10-50mm). Insert the grommet base through the hole and secure it from underneath the desk with the provided plate and nut.

Step 4.2: Attach VESA Plate to Monitor
Align the VESA plate with the mounting holes on the back of your monitor (75x75mm or 100x100mm). Secure the plate using the appropriate screws and washers from the hardware kit. Ensure the screws are tightened firmly but do not overtighten.
Step 4.3: Mount Monitor to Arm
Slide the VESA plate with the attached monitor onto the arm's mounting head. Ensure it clicks securely into place. For safety, it is recommended to have assistance when lifting and mounting larger monitors.

Step 4.4: Adjust Gas Spring Tension
The gas spring tension needs to be adjusted to match the weight of your monitor. Use the provided Allen key to turn the adjustment screw on the arm. Turn clockwise to decrease tension (for lighter monitors) or counter-clockwise to increase tension (for heavier monitors). Adjust until the monitor stays at any desired height without drifting up or down.
Step 4.5: Cable Management
Route your monitor cables (power, video, etc.) through the integrated cable management clips on the arm and along the pole. This helps maintain a tidy and organized workspace.
5. Operating the Monitor Arm
The HUANUO HNSS8-E monitor arm offers full-motion adjustments for optimal viewing comfort.
5.1 Height Adjustment
Gently push or pull the monitor to your desired height. The gas spring mechanism allows for smooth and effortless vertical movement. The arm can reach a maximum height of 62 cm (from the desk surface to the center of the VESA plate) and a minimum height of 36 cm.

5.2 Tilt, Swivel, and Rotation
The monitor arm allows for flexible positioning:
- Tilt: Adjust the monitor screen from +85° to -30° to reduce glare and find the best viewing angle.
- Swivel: Rotate the arm 180° at the base and 360° at the joint to share your screen with others.
- Rotation: Rotate the monitor 360° between landscape and portrait orientation.

6. Maintenance

- Clean the monitor arm with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Do not lubricate the gas spring mechanism. It is designed to be maintenance-free.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor sags or does not stay at desired height. | Gas spring tension is too low for the monitor's weight. | Increase gas spring tension by turning the adjustment screw counter-clockwise with the Allen key. |
| Monitor is difficult to move or too stiff. | Gas spring tension is too high for the monitor's weight. | Decrease gas spring tension by turning the adjustment screw clockwise with the Allen key. |
| Monitor wobbles or feels unstable. | Mounting clamp/grommet is not securely tightened, or VESA plate screws are loose. | Ensure the desk clamp/grommet mount is firmly secured to the desk. Check and tighten all VESA plate screws. |
| Cables are disorganized. | Cables are not routed through management clips. | Utilize the integrated cable management clips on the arm and pole to organize cables. |
