5.2. Choosing Your Mounting Option

Image: Two installation options: Grommet Mount (desk thickness 0.39"-3.15", hole diameter 0.39"-2.36") and C-clamp Mount (desk thickness 0.39"-4.53").
5.3. Installation Steps (General)
- Attach VESA Plate to Monitor: Secure the VESA plate to the back of your monitor using the appropriate screws from the hardware kit. Ensure it is centered and tightened securely.
- Install Desk Mount Base:
- For C-Clamp Mount: Attach the C-clamp base to the edge of your desk. Tighten the clamp screw until the base is firmly secured to the desk.
- For Grommet Mount: Insert the grommet base through the cable management hole in your desk. Secure it from underneath the desk using the provided washer and nut.
- Attach Monitor Arm to Base: Slide the monitor arm onto the pole of the installed desk mount base.
- Mount Monitor to Arm: Carefully slide the monitor (with VESA plate attached) onto the VESA head of the monitor arm until it clicks into place. Ensure it is securely locked.
- Adjust Gas Spring Tension: After mounting the monitor, adjust the gas spring tension to match your monitor's weight. This allows for smooth height adjustment. (Refer to Section 6.1 for detailed adjustment instructions).
- Route Cables: Use the integrated cable management channels on the arm to route your monitor cables for a clean and organized workspace.

6. Operation and Adjustments
Your MOUNTUP monitor arm offers full motion capabilities for optimal viewing comfort and productivity.
6.1. Gas Spring Tension Adjustment
The gas spring is pre-set to mid-tension. Adjust it based on your monitor's weight for smooth movement.
- Monitor Raises Up Too Easily / Doesn't Stay Down: Turn the adjustment screw clockwise (-) to reduce tension for lighter monitors.
- Monitor Drops Down / Is Hard to Raise: Turn the adjustment screw counter-clockwise (+) to increase tension for heavier monitors.
- Note: Hold the arm in a horizontal position while adjusting. The number of turns depends on the display's weight; it may take up to 17 turns.

6.2. Tilt Angle Adjustment
- Loosen the tilting bolt (turn in "-" direction).
- Adjust the monitor to your desired tilt angle (+90° to -45°).
- Retighten the tilting bolt (turn in "+" direction).
6.3. Full Range Motion
The arm allows for various movements to customize your viewing experience:
- Rotation: 360° for landscape or portrait orientation.

7. Maintenance
Regular maintenance will ensure the longevity and optimal performance of your MOUNTUP monitor arm:
- Cleaning: Wipe the surface with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Check Connections: Periodically check all screws and bolts to ensure they remain tight. Retighten if necessary.
- Gas Spring: The gas spring is designed for long-term use and generally requires no maintenance. If you notice a change in performance, re-adjust the tension as described in Section 6.1.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor arm sags or won't stay at desired height. | Gas spring tension is too low for monitor weight. | Increase gas spring tension by turning the adjustment screw counter-clockwise (+). Ensure monitor is within weight capacity. |
| Monitor arm is too stiff or hard to move up. | Gas spring tension is too high for monitor weight. | Decrease gas spring tension by turning the adjustment screw clockwise (-). |
| Monitor tilts downwards. | Tilting bolt is not tight enough. | Loosen the tilting bolt, adjust to desired angle, then retighten firmly. |
| Mount is unstable or wobbles. | Mounting base is not securely tightened to the desk. | Re-tighten the C-clamp or grommet base. Ensure desk thickness is within specified range. |
| Cables are not neatly organized. | Cables not routed through channels. | Open the cable management covers on the arm and route cables through them. Close covers securely. |
