The article mentions that the Club3D adapters don't exist anymore (=the popular ones), only off-brand alternatives. VRR is not officially supported via adapters, a big problem for a gaming device.
I have it, it does not. Well, it may. It depends on the firmware you install on the cable. Depending on the firmware, different things will be broken. I tried them all. There's no version that will consistently support 2160p@120 and 4:4:4/RGB and HDR and VRR, and without random handshake issues.
