## Description

The HX Monitor Arm is the perfect accessory to save desk space and add superior ergonomics to a large monitor up to 42 lbs (19 kg). In the box: HX arm, extension, monitor pivot, VESA adapter, desk clamp, grommet mount and attachment hardware. Connects to VESA hole patterns 75x75mm, 100x100mm, 200x100mm, 100x200mm and 200x200mm. Display depth greater than 6 inches (15 centimeters) will reduce weight capacity to 28 lbs (12.7 kg). For a curved monitor, consider the arc’s depth to determine compatibility.

Review: 長いアームの先のくそでかモニターが空中でぴたっと止まる。位置調整すすーーっとしても、またピタッ。 どういう仕組みかわからないけど魔法のようなアームです。物理の法則が壊れてるように見えます😨 大型ペンタブレットを浮かせるためにこういうのが必要でした。揺れにくいし、わがままな配置を叶えてくれます！💕

## Questions & Answers

**Q: Does it raise high enough to have two ultra wide monitors on top of each other?**
A: If anyone is looking for a double mount, still, there is actually a mount made just for this purpose. "Peerless B-MIS38426 1x2 Bolt Down Desktop Mount for 43" & 49" Ultrawide Curved Monitors ".  I found it while looking for a mount like the Ergotron.

**Q: How thick should a table be in order to securely position the arm and screen?**
A: I've had it clamped to 1/2" desk and it is solid as a rock. The arm tells you where to set the clamp depending on the size of the desk, so yes you can go less than 1" and 1/2" works fine.

**Q: Does the installation requires this to be screw to the wall?**
A: It does not require you to attach it to the wall.  It is attached to the desk and is very sturdy.

**Q: It says for ultra wide moniters but can i use this with a 32 inch odyssey neo g7?**
A: Yes,  is the HX Ultrawide is  compatible with the  32 inch odyssey neo g7.

*by D***L on 7 April 2022*

Love it, it's fantastic. Does exactly what it says it does. The lower arm only pivots 180 degrees, from left to right, over the desk. It will not pivot behind the desk. It's clearly in the description and images but I still missed it.
