3. Setup and Installation
Follow these steps carefully to install your ErGear Dual Monitor Mount.
Step 3.1: Choose Mounting Type
The monitor mount supports two installation methods: C-Clamp and Grommet Mount. Choose the method that best suits your desk.
- C-Clamp Mount: Ideal for desks with an edge. Desk thickness compatibility: 0.39"-2.76" (10-70mm).
- Grommet Mount: Requires a hole in the desk. Desk thickness compatibility: 0.39"-2.76" (10-70mm). Hole diameter compatibility: 0.39"-2.36" (10-60mm).

Step 3.2: Assemble the Base
Assemble the chosen base (C-Clamp or Grommet) according to the detailed instructions in the included manual. Ensure it is securely fastened to your desk.
Step 3.3: Attach VESA Plate to Monitor
Carefully attach the VESA plate to the back of your monitors using the provided screws. Ensure the screws are tightened securely but do not overtighten.

If your monitor is not VESA compatible, use the Universal VESA Adapter Kit. This kit fits flat LCD LED OLED monitor screens with thickness from 1.18 inches to 2.95 inches. Please note it is not compatible with curved screens.
Step 3.4: Install Monitor Arms
Slide the monitor arms onto the central pole of the base. Adjust their height and orientation as needed. Secure the arms by tightening the designated screws.
Step 3.5: Mount Monitors
Carefully slide the monitors (with VESA plates attached) onto the ends of the monitor arms. Ensure they click into place or are secured with the locking mechanism.
4. Operating Instructions
The ErGear Dual Monitor Mount offers extensive adjustability for optimal viewing comfort.
4.1: Adjusting Spring Tension
The gas spring arms allow for smooth height adjustments. If a monitor sags or floats up, you may need to adjust the spring tension. Use the provided Allen key to turn the screw located on the arm. Turn clockwise to increase tension (for heavier monitors) and counter-clockwise to decrease tension (for lighter monitors).
4.2: Swivel, Tilt, and Rotation
Each monitor can be independently adjusted:
- Swivel: Rotate the monitor horizontally up to 360 degrees.
- Tilt: Adjust the vertical angle of the monitor from +90 degrees (upward) to -35 degrees (downward).
- Rotation: Rotate the monitor from landscape to portrait orientation (360 degrees).

5. Maintenance
To ensure the longevity and optimal performance of your ErGear Dual Monitor Mount, follow these simple maintenance tips:
- Regular Cleaning: Wipe down the mount with a soft, damp cloth to remove dust and debris. Avoid abrasive cleaners.
- Check Tightness: Periodically check all screws and bolts to ensure they remain tight. Re-tighten if necessary to maintain stability.
- Lubrication: The gas spring mechanism is designed for maintenance-free operation. Do not attempt to lubricate internal components.
6. Troubleshooting
If you encounter any issues with your monitor mount, refer to the following common solutions:
- Monitor Sags or Floats: Adjust the gas spring tension as described in Section 4.1. Ensure the monitor weight is within the specified range (up to 22 lbs).
- Difficulty Adjusting: Check if the tension is too high or too low for your monitor's weight. Adjust the spring tension accordingly. Ensure all joints are not overtightened, allowing for smooth movement.
- Mount is Unstable: Verify that the desk clamp or grommet mount is securely tightened to the desk. Ensure the desk surface is stable and can support the weight of the mount and monitors.
- VESA Adapter Issues: Ensure the monitor thickness is within the compatible range (1.18" to 2.95") and that it is a flat screen, as the adapter is not compatible with curved screens.
