4.1. Assemble the Vertical Pole

- Attach the assembled pole to the tempered glass base using the provided screws and Allen wrench.
4.2. Choose and Install Mounting Method
The stand offers two primary mounting options: C-Clamp or Grommet. Select the method suitable for your desk.

C-Clamp Mounting:
- Attach the C-clamp bracket to the desk edge and tighten the knob until secure.
Grommet Mounting:
- If your desk has a grommet hole, use the grommet base hardware to secure the stand through the hole.
4.3. Attach VESA Plates to Monitors
- Carefully place your monitor face down on a soft, clean surface.
- Align the VESA plate with the mounting holes on the back of your monitor.
- Secure the VESA plate using the appropriate screws and spacers provided. Ensure all four screws are tightened.
4.4. Mount Monitors to the Stand

- Secure each monitor head in place using the locking knobs or screws.

4.5. Cable Management
Use the included cable clips to route your monitor cables neatly along the back of the vertical pole. This helps maintain a clean and organized workspace.
5. Operating Instructions
5.1. Height Adjustment
The monitor stand features 13 distinct height settings, allowing you to position your monitors at an ergonomic level. To adjust the height, loosen the locking mechanism on the monitor head, slide the monitor to the desired position, and then re-tighten the lock.

5.2. Tilt Adjustment
Adjust the monitor's vertical angle with a tool-free tilt range of -15° to +10°. This allows you to reduce glare and find the most comfortable viewing angle.

5.3. Swivel and Rotation
The monitor mount allows for a +/-50° swivel, enabling you to share your screen easily. Additionally, smaller monitors can be rotated 360° for instant portrait or landscape orientation.

6. Maintenance
- Regularly check all screws and connections to ensure they remain tight and secure.
- Clean the stand and base with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the finish.
- Ensure cables are properly managed to prevent strain or damage.
7. Troubleshooting
7.1. Monitor Wobbles or Sags
- Solution: Ensure all screws, especially those connecting the monitor heads to the pole and the VESA plates to the monitors, are securely tightened. Verify that the total weight of your monitors does not exceed the 44 lbs (20 kg) maximum load capacity.
7.2. VESA Plate Does Not Fit Monitor
- Solution: Double-check your monitor's VESA mounting pattern. This stand supports 50x50mm, 75x75mm, and 100x100mm. If your monitor has a different pattern, it may not be compatible. Ensure you are using the correct screws and spacers for your monitor's depth.
7.3. Difficulty Adjusting Monitor Position
- Solution: Loosen the relevant adjustment screws or knobs slightly before attempting to move the monitor. Once in the desired position, re-tighten them firmly.
