4. Setup
4.1 Pre-Installation Checks
Before beginning installation, ensure your monitor and desk meet the compatibility requirements:
- Monitor Size: Compatible with ultrawide monitors up to 49 inches and standard flat/curved monitors up to 35 inches.
- Monitor Weight: Supports monitors weighing up to 33 lbs (15 kg).
- VESA Pattern: Supports VESA mounting patterns of 75x75mm and 100x100mm.
- Desk Thickness: Compatible with desks 0.39" to 1.77" (10mm to 45mm) thick for both C-clamp and Grommet Base installations.

This diagram illustrates the compatibility specifications for the monitor arm. It supports monitors from 13 to 49 inches, with VESA patterns of 75x75mm or 100x100mm, and a maximum weight capacity of 33 pounds per arm.
4.2 Mounting Options (C-Clamp / Grommet Base)
The monitor arm offers two installation methods: C-clamp for desk edges or Grommet Base for desks with a pre-drilled hole.

This image shows the two primary installation methods: the C-clamp and the Grommet Base. Both options are suitable for desks with a thickness ranging from 0.39 to 1.77 inches, providing versatile mounting solutions.
C-Clamp Installation:
- Attach the C-clamp to the main pole and secure it to the edge of your desk.
- Tighten the clamp screw until the mount is firmly secured to the desk.
Grommet Base Installation:
- Insert the grommet bolt through the desk hole and secure the base plate from underneath.
- Attach the main pole to the grommet base and tighten securely.
4.3 Attaching the Monitor and Gas Spring Adjustment
- Attach the VESA plate to the back of your monitor using the appropriate screws from the hardware kit.
- Slide the monitor with the attached VESA plate onto the arm's mounting head. Ensure it clicks into place securely.
- Gas Spring Tension Adjustment: Once the monitor is mounted, adjust the gas spring tension to match your monitor's weight. Use the provided Allen wrench to turn the adjustment screw.
- Turn clockwise (towards '-') for lighter monitors to reduce tension.
- Turn counter-clockwise (towards '+') for heavier monitors to increase tension.
- Note: Keep the arm in a horizontal level during adjustment for best results.

This illustration demonstrates the gas spring tension adjustment. To increase tension for heavier monitors, turn the screw counter-clockwise. For lighter monitors, turn it clockwise. Ensure the arm is held horizontally during adjustment.
5. Operating
5.1 Monitor Adjustments
The WALI Ultrawide Monitor Arm allows for flexible positioning to achieve optimal viewing angles and ergonomic comfort:
- Tilt: Adjust the monitor +450/-450 to reduce glare and find your preferred angle.
- Swivel: Swivel the monitor +900/-900 to share your screen or change viewing direction.
- Rotation: Rotate the monitor 1800 from landscape to portrait mode for different tasks.
- Height Adjustment: The gas spring arm allows smooth vertical height adjustments.

This diagram highlights the arm's full adjustability, allowing for a tilt range of +/-45 degrees, a swivel range of +/-90 degrees, and a full 360-degree rotation for optimal viewing angles.

This diagram indicates the maximum vertical reach of 21.7 inches and a maximum horizontal extension of 20.2 inches, providing ample adjustability for various desk setups.
5.2 Ergonomic Benefits
Proper positioning of your monitor can significantly improve comfort and reduce strain. Adjust the monitor arm so that the top of your screen is at or slightly below eye level, and your eyes are approximately an arm's length from the screen. This helps maintain a neutral posture and alleviates neck and eye fatigue.

These images illustrate the ergonomic benefits of using the monitor arm, showcasing how proper monitor positioning can reduce neck strain and improve overall comfort during extended use.
5.3 Cable Management
The monitor arm features integrated cable management clips to keep your workspace tidy. Route your monitor and power cables along the arm and through the clips to maintain a clean and organized setup.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your WALI monitor arm.
- Cleaning: Wipe the surface of the monitor arm with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Inspection: Periodically check all screws and connections to ensure they are tight and secure. Re-tighten if necessary.
- Gas Spring: The gas spring is designed for long-term use (over 20,000 fatigue tests). If you notice a significant change in tension or difficulty holding the monitor's position, re-adjust the gas spring tension as described in Section 4.3.
7. Troubleshooting
If you encounter issues with your monitor arm, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor arm sags or does not hold position. | Gas spring tension is too low for monitor weight. | Increase gas spring tension by turning the adjustment screw counter-clockwise (towards '+'). Refer to Section 4.3. |
| Monitor arm is too stiff to move. | Gas spring tension is too high for monitor weight. | Decrease gas spring tension by turning the adjustment screw clockwise (towards '-'). Refer to Section 4.3. |
| Monitor wobbles or feels unstable. | Mounting screws or clamp are loose. | Ensure all mounting screws (VESA plate, arm joints, desk clamp/grommet) are securely tightened. |
| Monitor does not fit the VESA plate. | Incorrect VESA pattern or adapter needed. | Verify your monitor's VESA pattern (75x75mm or 100x100mm). If different, a VESA adapter (sold separately) may be required. |
