4. Setup and Installation
Follow these steps to properly install your Secretlab Magnus Monitor Arm:
- Prepare Your Desk: Ensure your desk surface is between 10mm and 50mm thick for proper C-clamp installation. Clear the area where the monitor arm will be mounted.

- Mount the VESA Plate: Attach the VESA plate to the back of your monitor. This arm features an extra-secure VESA plate with a unique double lock mechanism. Twist Lock 1 clockwise to lock, then press down and turn each Lock 2 screw to fully tighten. This ensures your ultrawide monitor remains securely in place.
