2.3 Mounting the Stand to Your Desk
The stand offers two installation methods: C-clamp or grommet mounting. Both methods are suitable for desk thicknesses between 0.4 inches and 3 inches (10-74.5mm).
Method 1: C-Clamp Installation
- Position the C-clamp base on the edge of your desk.
- Tighten the C-clamp screw until the stand is firmly secured to the desk. Ensure it is stable and does not wobble.
Method 2: Grommet Mounting (Perforated Installation)
- If your desk has a grommet hole, insert the grommet base through the hole.
- Secure the base from underneath the desk using the provided plate and screw.

3. Operating Instructions
The HEMUDU monitor arm provides various adjustment options to customize your viewing experience.
3.1 Height Adjustment
The monitor's height can be adjusted by repositioning the VESA plate along the vertical pole. Loosen the safety lock screw, slide the monitor to the desired height, and then re-tighten the screw to secure it.
