- Rotation: Rotate your monitors 360° for landscape or portrait orientation.
- Tilt: Tilt the monitor ±80° up or down to reduce glare and optimize viewing angles.

Gas Spring Tension Adjustment
The gas spring tension needs to be adjusted according to the weight of your monitors to ensure they stay in place and move smoothly.
- For Lighter Monitors: If the arm tends to rise too easily or does not stay down, turn the adjustment screw counter-clockwise (towards the "-" sign) to decrease the gas spring tension.
- For Heavier Monitors: If the arm tends to sink or is difficult to raise, turn the adjustment screw clockwise (towards the "+" sign) to increase the gas spring tension.

Cable Management
To maintain a clean and organized workspace, utilize the integrated cable management system:
- Plug the power cord into the cable case (Z1) and snap it into the arm.
- Screw back any screws you removed earlier to secure the cable cases.
- Finish the rest of the cable cases (Z1) and fasten the cable case cap (Z2).
- Plug all power cables into the wire clip (G) on the pole.
Maintenance
Regular maintenance ensures the longevity and safe operation of your monitor mount.
- Cleaning: Wipe the mount with a soft, damp cloth. Avoid abrasive cleaners or solvents that may damage the finish.
- Check Tightness: Periodically check all screws and connections to ensure they are securely tightened. Loose connections can affect stability and safety.
- Gas Spring: If you notice changes in arm movement or stability, re-adjust the gas spring tension as described in the Operating Instructions.
Troubleshooting
Here are solutions to common issues you might encounter with your triple monitor arm.
Common Problems and Solutions
- Arm Sinking / Unable to Lift: If the monitor arm sinks or is difficult to lift, the gas spring tension needs to be increased. Rotate the adjustment screw clockwise (towards the "+" sign) using the provided wrench until the arm holds the monitor's weight.
- Monitor Head Sinking: If the monitor itself tilts downwards or cannot maintain its angle, the tilt mechanism needs tightening. Use a wrench to tighten the head of the bracket clockwise.
- Arm Bouncing / Difficult to Press Down: If the arm bounces up or is difficult to press down, the gas spring tension is too high. Rotate the adjustment screw counter-clockwise (towards the "-" sign) to reduce air pressure until the arm moves smoothly.
