Setup and Installation
The Thermaltake Dual RGB Monitor Arm supports two installation methods: desk clamp and grommet mount. Choose the method suitable for your desk.
1. Desk Clamp Installation
- Attach the Clamp: Secure the desk clamp assembly to the edge of your desk. Ensure the clamp is tightened firmly to prevent movement. The clamp supports desk thicknesses from 10 mm to 85 mm.

- Insert the Main Pole: Place the main pole of the monitor arm into the clamp base. Tighten any securing screws on the clamp to hold the pole in place.
2. Grommet Mount Installation
- Prepare the Grommet Hole: If your desk has a grommet hole, ensure it is clear. If not, you may need to drill a hole (consult a professional if unsure). The grommet mount supports desk thicknesses from 10 mm to 48 mm.
- Assemble Grommet Components: Follow the instructions provided with the grommet mount components to secure the main pole through the desk hole. Tighten the bottom plate and nut securely from underneath the desk.
3. Attaching Monitor Arms and VESA Plates
- Attach Arms to Pole: Slide the monitor arms onto the main pole at your desired height. Secure them using the provided screws or levers.
- Attach VESA Plates to Monitors: Remove the VESA plates from the monitor arms. Attach one VESA plate to the back of each monitor using the appropriate screws from the hardware kit. Ensure the screws are tightened securely but do not overtighten. The VESA plates are compatible with 75x75mm and 100x100mm patterns.
- Mount Monitors: Carefully slide the monitors (with attached VESA plates) onto the monitor arms. Ensure they click into place or are secured with any locking mechanisms.

4. Cable Management
Route your monitor and power cables through the integrated cable management channels on the arms and main pole to maintain a tidy workspace.
Operation and Adjustments
The Thermaltake Dual RGB Monitor Arm offers extensive adjustability for optimal viewing comfort.
1. Gas Spring Tension Adjustment
The gas spring system allows for smooth height adjustment. If your monitor sags or springs up too easily, adjust the tension using the provided Allen wrench. Turn clockwise to increase tension (for heavier monitors) or counter-clockwise to decrease tension (for lighter monitors). Adjust gradually until the monitor stays in position when released.
2. Monitor Positioning
- Height Adjustment: Gently push or pull the monitor up or down to adjust its vertical position.
- Tilt: Tilt the monitor screen +50° upwards or -20° downwards to find your preferred viewing angle.
- Swivel: Swivel the monitor arm +90° to -90° horizontally.
- Rotation: Rotate the monitor screen +108° to -108° for landscape or portrait orientation.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your monitor arm.
- Cleaning: Wipe the arm surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or RGB components.
- Check Connections: Periodically check all screws and bolts, especially those securing the clamp/grommet mount and VESA plates, to ensure they remain tight.
- Gas Spring Adjustment: Re-adjust the gas spring tension if you change monitors or notice any sagging over time.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor sags or drops | Gas spring tension is too low for monitor weight. | Increase gas spring tension using the Allen wrench (clockwise). |
| Monitor springs up too easily | Gas spring tension is too high for monitor weight. | Decrease gas spring tension using the Allen wrench (counter-clockwise). |
| Arm is unstable or wobbles | Desk clamp/grommet mount is not tightened sufficiently. | Ensure the desk clamp or grommet mount is securely fastened to the desk. Check all connection points. |
| Monitors are not level | Minor misalignment during VESA plate attachment or arm installation. | Adjust the tilt/rotation of the VESA plate or arm connection point. Some arms have a small leveling screw. |
| RGB lighting not working | Power connection issue or internal fault. | Ensure the USB power cable for the RGB lighting is properly connected. If the issue persists, contact support. |
