Not really. That same link talks about how Intel and nvidia drivers can provide HDMI 2.1 on Linux but it is via their non-free firmware blob.

AMD doesn't (can't? won't?) do the same but there is a workaround: a DisplayPort to HDMI adapter using a particular chip running hacked firmware. That'll get you 4K 120 Hz with working FreeSync VRR.

Some of us would like our expensive hardware to work without hacked third party dongles.


All of us would like our expensive hardware to work without hacked third party dongles. But given that this isn't possible with AMD open source drivers at the present time, this is the best we'll get for now.

I don't remember where,but somebody explained that the adapters also have some kind of limitation. I can't remember what but they went into deep details and the whole thing is revolting. Governments should protect open source.
