Setup and Installation
Before beginning installation, ensure you have all components and tools as listed in the packaging. The AOC AM420G offers two primary mounting options: C-Clamp and Grommet.
1. Choose Your Mounting Option
Determine whether to use the C-Clamp or Grommet mounting base based on your desk type and preference. The C-Clamp is suitable for desk edges, while the Grommet mount requires a pre-drilled hole in your desk.
Figure 3: Illustration of the C-Clamp and Grommet mounting options for the monitor stand. The C-Clamp secures to the edge of a desk, while the Grommet mount passes through a desk hole.
- C-Clamp: Suitable for desktop thickness between 0.59" and 1.97" (1.5 cm to 5 cm).
- Grommet Mount: Requires a desk hole with a diameter greater than 2.36" (6 cm).
2. Assemble the Base
Follow the specific instructions provided in your product packaging for assembling the chosen mounting base to the main pole of the monitor arm.
3. Attach Monitor Arms
Slide the monitor arms onto the main pole. Ensure they are at the desired height before tightening the securing screws.
4. Mount Monitors
Attach your VESA-compatible monitors to the mounting plates on each arm. Ensure the VESA pattern (100x100mm or 75x75mm) matches your monitor. Secure the monitors firmly with the provided screws.
5. Adjust Tension
The monitor arm features a durable mechanical spring system. Adjust the tension using the integrated adjustment mechanism to match the weight of your monitors. This ensures smooth and stable positioning.

Operating Instructions
The AOC AM420G monitor stand provides extensive flexibility for ergonomic comfort. Once installed, you can easily adjust your monitors to your preferred viewing angles and positions.
Adjusting Monitor Position
- Height Adjustment: Gently push or pull the monitor up or down along the pole or arm to achieve the desired vertical position. The mechanical spring will assist in holding the position.
- Extension/Retraction: Extend or retract the arms to bring the monitors closer or further away from you. The maximum extension is 470mm.
- Tilt: Tilt your monitor screen up or down between -15° and +90° to reduce glare and optimize viewing angle. The optimized tilting structure ensures stable placement.
- Swivel: Swivel your monitor left or right between -90° and +90° for collaborative work or to change viewing orientation.
- Rotation: Rotate your monitor from landscape to portrait mode as needed.

Maintenance
The AOC AM420G monitor stand is designed for durability and requires minimal maintenance. Regular cleaning and occasional checks will ensure its longevity and optimal performance.
- Cleaning: Use a soft, dry cloth to wipe down the surfaces of the monitor arm. For stubborn marks, a slightly damp cloth with mild soap can be used, followed by drying. Avoid abrasive cleaners or solvents.
- Joint Checks: Periodically check all joints and screws to ensure they remain securely tightened. If any looseness is detected, gently tighten the corresponding screws. Do not overtighten.
- Spring Tension: If you notice that your monitor is not holding its position as firmly as before, or if it drifts, re-adjust the spring tension as described in the "Setup and Installation" section.
Troubleshooting
This section addresses common issues you might encounter with your AOC AM420G Dual Monitor Stand.
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor sags or does not hold position. | Spring tension is too low for the monitor's weight. | Increase the spring tension using the adjustment screw on the arm. Refer to the "Adjust Tension" step in the Setup section. |
| Monitor is difficult to move up or down. | Spring tension is too high for the monitor's weight. | Decrease the spring tension using the adjustment screw on the arm. |
| Monitor wobbles or feels unstable. | Mounting base or arm joints are not securely tightened. | Ensure the C-Clamp or Grommet mount is firmly secured to the desk. Check and tighten all screws on the arm joints and VESA plate. |
