Hello, I took a "Xantron MA-HD-RGB" which I was able to get for 69.00 and the adapter for the vesa is the "Xantron VESA Adapter Plate" which I was able to get for 20.00.
Both products were purchased from digiec. The arm just needs to have the necessary strength to carry the weight of the screen (put a little margin) so equal for the type or brand. and the adapter is mandatory to be able to put this screen on an articulated arm type vesa. I hope I've answered your question.
Ps: the setup of this screen as a monitor with an articulated arm is just incredible for my use is a pure delight. Enjoy

Sorry, I don't use them.
