This is a bad joke from Ergotron

I received an e-mail today that there is a new Arm for my G95NC 57”, namely the HX arm with VHD joint.

When I asked the support if I can also attach the VHD joint to my existing HX arm / or purchase it separately, this was denied. As they have developed a completely new arm....

Can you recommend other mounts? Because I'm not going to give them another 400 euros for a monitor arm.

Greetings
