Setup and Installation
The HUANUO Dual Monitor Stand offers two primary installation methods: C-Clamp and Grommet. Choose the method best suited for your desk.
1. Choose Installation Method

Figure 2: C-Clamp and Grommet Mounting Options
This image illustrates the two available installation methods for the monitor stand. The C-Clamp mounting option is suitable for desks with a maximum thickness of 3.3 inches, clamping directly to the edge of the desk. The Grommet mounting option requires a pre-existing hole in your desk (or drilling one) and supports desk thicknesses up to 2.7 inches.
C-Clamp Installation
- Attach the C-clamp bracket to the main pole using the provided screws.
- Position the C-clamp on the edge of your desk.
- Tighten the C-clamp screw until the stand is securely fastened to the desk. Ensure it is stable and does not wobble.

This video demonstrates the step-by-step process for installing the monitor stand using the C-Clamp method. It shows how to attach the clamp to the pole and secure it to the desk edge, highlighting the maximum desk thickness of 3.1 inches for this method.
Grommet Installation
- If your desk does not have a grommet hole, you may need to drill one (consult a professional if unsure).
- Insert the main pole through the grommet hole.
- Attach the grommet base plate and tighten the screw from underneath the desk to secure the stand.

Operating and Adjustments
The HUANUO Dual Monitor Stand offers various adjustment options to achieve your optimal viewing experience.
- Height Adjustment: Loosen the collar on the main pole to slide the monitor arms up or down. Retighten the collar to secure the desired height. Each monitor can also be individually adjusted vertically by up to 3 inches using the screw mechanism on the VESA plate.
- Swivel: The monitor arms can swivel horizontally to adjust viewing angles.
- Tilt: Adjust the tilt angle of your monitors (up to 45 degrees) to reduce glare and improve ergonomics.
- Rotation: Rotate your monitors from landscape to portrait orientation as needed.

Maintenance
Regular maintenance ensures the longevity and safe operation of your monitor stand.
- Cleaning: Wipe the stand with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Tightening: Periodically check all screws and connections, especially those securing the stand to the desk and the monitors to the VESA plates. Tighten any loose fasteners to maintain stability.
- Lubrication: If joints become stiff, a small amount of silicone-based lubricant can be applied to pivot points, though this is generally not required for normal operation.
Troubleshooting
If you encounter issues with your monitor stand, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor sags or does not hold height. | Screws securing the monitor arm to the pole or the VESA plate to the monitor are loose. Monitor weight exceeds capacity. | Ensure all screws are securely tightened. Verify monitor weight is within the 26 lbs per arm limit. For individual monitor height adjustment, ensure the screw mechanism is fully tightened after setting the desired height. |
| Stand is wobbly or unstable. | Desk clamp or grommet mount is not tight enough. Desk surface is too thin or unstable. | Retighten the C-clamp or grommet screw. Ensure your desk meets the minimum thickness requirements and is sturdy. Consider adding a reinforcement plate if your desk is thin. |
| Monitor adjustments (swivel, tilt) are too stiff or too loose. | Tension screws for joints are incorrectly adjusted. | Use the provided hex keys to adjust the tension screws on the joints. Tighten for more resistance, loosen for less. Adjust gradually until desired movement is achieved. |
| Missing parts or damaged components. | Manufacturing defect or shipping damage. | Do not attempt to assemble. Contact HUANUO customer support immediately for replacement parts. |
