Looks like it can do 4k 120hz, but since it's limited to HDMI 2.0 it will have to rely on 4:2:0 chroma subsampling to get there. Unfortunately the lack of HDMI 2.1 might be down to politics, the RDNA3 GPU they're using should support it in hardware, but the HDMI Forum has blocked AMD from releasing an open source HDMI 2.1 implementation.

It seems it supports DP 1.4 as well, so perhaps you could get an adapter if your display only supports HDMI 2.1
I'm not sure that would work. From what I can tell, the adapters are basically dumb straight through cables, they aren't converting anything. And it's the actual GPU that's outputting a HDMI signal over the Displayport connector, which the adapter than rewires in to a HDMI shaped connector.

There are two kinds of DP to HDMI adapters. The passive ones are like you said, they need special support on the GPU (these ports are usually labelled as DP++), IIRC they only do some voltage level shifting. The active ones work on any DP port (they don't need AFAIK any special support on the GPU), and they do the full protocol conversion.
I was able to use this adapter to get my 2070s DisplayPort output to send 4k120hz to my TV, which only has HDMI ports.

... but isn't it using a wireless dongle to connect to the headset to the PC so HDMI doesn't get involved?
It seems to me the wireless is pretty important. I have an MQ3 and I have the link cable. For software development I pretty much have to plug the MQ3 into my PC and it is not so bad to wander around the living room looking in a Mars boulder from all sides and such.
For games and apps that involve moving around, particularly things like Beat Saber or Supernatural the standalone headset has a huge advantage of having no cable. If I have a choice between buying a game on Steam or the MQ3 store I'm likely to buy the MQ3 game because of the convenience and freedom of standalone. A really good wireless link changes that.

I'm talking about the Steam Machine here. In theory you could pipe 4k120 to the headset assuming there's enough wireless bandwidth, yeah.
