Step 2: Choose and Install Desk Mount Method
Option A: Desk Clamp Installation
- Assemble the desk clamp base according to the diagrams in the included manual.
- Position the clamp base at the desired location on your desk edge.
- Tighten the clamp screw until the base is firmly secured to the desk. Ensure the desk thickness is within the specified range (typically 10-90mm).

Option B: Grommet Mount Installation
- If your desk has a grommet hole, or if you plan to drill one (consult a professional if drilling), use the grommet mount base.
- Assemble the grommet base components as shown in the manual.
- Insert the grommet base through the desk hole and secure it from underneath with the provided plate and nut.

Step 3: Attach Monitor to Arm
- Carefully lift the monitor (with the VESA plate attached) and slide it onto the mounting head of the articulated arm.
- Ensure the monitor is securely seated and tighten any locking screws if present.
Step 4: Connect USB Cables
- Locate the two integrated USB 3.0 ports on the base of the monitor arm.
- Connect the provided USB 3.0 cables from the arm's base to available USB ports on your computer. This enables the arm's USB ports for data transfer and charging.

4. Operating Instructions
The ELG F90USB monitor arm provides flexible adjustments for optimal ergonomic positioning.
Gas Spring Tension Adjustment
The gas spring allows for smooth, tool-free height adjustments. It must be calibrated to your monitor's weight for proper function.
- If the monitor drifts down, the tension is too low. Use the provided Allen key to turn the adjustment screw clockwise (towards '+') to increase tension.
- If the monitor floats up or is difficult to push down, the tension is too high. Turn the adjustment screw counter-clockwise (towards '-') to decrease tension.
- Adjust gradually until the monitor stays at any desired height with minimal effort.

Monitor Positioning
- Height Adjustment: Gently push or pull the monitor to raise or lower it. The gas spring will assist in holding the position. The arm allows for a height adjustment range of 150mm to 400mm.
- Tilt: Tilt the monitor screen up or down to achieve the desired viewing angle. The tilt range is +85° to -30°.
- Swivel: Rotate the monitor horizontally (left or right) up to 220° at the arm joints.
- Rotation: Rotate the monitor 360° from landscape to portrait orientation.

Cable Management
The ELG F90USB features integrated cable management to keep your workspace tidy. Route your monitor's power and video cables, as well as the USB cables, through the designated clips or channels along the arm. Close the covers to conceal the cables.
Using the USB Ports
The two USB 3.0 ports on the base of the arm provide convenient access for connecting peripherals or charging devices. Once the arm's USB cables are connected to your computer, these ports will function as standard USB ports.

5. Maintenance
- Cleaning: Wipe the mount with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Regular Checks: Periodically check all screws and fasteners to ensure they remain tight. Re-tighten if necessary.
- Gas Spring: If the gas spring performance changes over time, re-adjust the tension as described in the Operating Instructions.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor drifts down or cannot hold position. | Gas spring tension is too low for the monitor's weight. | Increase gas spring tension by turning the adjustment screw clockwise with the Allen key. |
| Monitor floats up or is difficult to push down. | Gas spring tension is too high for the monitor's weight. | Decrease gas spring tension by turning the adjustment screw counter-clockwise with the Allen key. |
| Monitor is wobbly or unstable. | Mounting screws are loose, or desk clamp/grommet is not tight. | Check and tighten all mounting screws, including those securing the VESA plate to the monitor and the base to the desk. |
| USB ports on the base are not working. | USB cables from the arm are not connected to the computer, or there is a cable issue. | Ensure the USB 3.0 cables from the arm's base are securely connected to functional USB ports on your computer. Try connecting a different device to test the ports. If issues persist, try different USB cables. |
| Monitor cannot be rotated 360 degrees. | Obstruction or incorrect VESA plate attachment. | Ensure no cables or parts are obstructing the rotation. Verify the VESA plate is centered and correctly attached. |
