Smooth movement and great reach
The extension arm is long enough to pull the screens right up to my face when needed, then push them back against the wall. The friction holds the position perfectly without drifting down over time. Very happy with this purchase.

Solid build quality for dual setups
This stand is incredibly sturdy. I have two 27-inch monitors mounted on it, and there is absolutely no wobble. The mechanical lift mechanism makes height adjustments smooth and effortless. Highly recommended for anyone looking to clean up their desk space.

Perfect for my All-in-One PC
I was worried about compatibility with my All-in-One computer, but the VESA adapter kit included worked perfectly. The cable management clips keep everything tidy. It feels very premium compared to other plastic arms I've tried.

Transformed my workspace
Best investment for my home office. The ability to rotate screens vertically is great for reading documents. The black finish looks professional and matches my monitors perfectly. Installation was straightforward with the provided tools.

Great value, minor assembly quirks
Overall a fantastic monitor arm for the price. The range of motion is excellent, allowing me to switch between landscape and portrait modes easily. Assembly took about 20 minutes; just make sure you tighten the tension screws correctly based on your monitor weight.

Good ergonomics, heavy duty
This arm definitely improved my posture. Being able to adjust the height so precisely helps reduce neck strain during long coding sessions. The only reason for 4 stars is that the clamp is quite large, so ensure your desk edge can accommodate it.
Q: Will this work with a curved 32-inch monitor?
A: Yes, as long as your curved monitor weighs under 9kg and has a VESA mounting pattern of 75x75mm or 100x100mm, the AM400P will support it securely.
Q: Does the package include cables for connecting the monitors?
A: No, this package contains only the mechanical stand, mounting hardware, and cable management clips. You will need to purchase HDMI, DisplayPort, or USB-C cables separately to connect your monitors to your computer.
Q: Does this stand support two separate monitors or just one?
A: The AM400P is designed as a single-arm mechanical lift stand. While it supports heavy loads up to 9kg which could technically hold a dual-monitor bracket attached to it, it is primarily sold as a single monitor solution. For native dual-screen support, please check our dual-arm models.
Q: What is the maximum thickness of the desk this clamp can fit?
A: The C-clamp included with the AM400P can accommodate desk thicknesses ranging from 10mm up to 60mm. If your desk is thicker, you may need to use the grommet mount option if your desk has a hole.
Q: Can I mount an Apple iMac on this stand?
A: Yes, newer iMacs have built-in VESA holes. For older models without VESA patterns, you will need a specific third-party VESA adapter kit for iMacs, which can then be attached to this arm.
