ROG Ally Z1 Extreme Dock for 4K/1440p/60/120fps/VRR streaming and emulation

Hi all, I'm looking to mainly use my Ally docked for emulation and Moonlight streaming and am looking for the goldilocks of docks. I have searched but there doesn't seem to be a great answer on which dock to get.

I'm looking for the following:

  • 1440p at 120hz
  • 4K at 60hz, ideally 120hz
  • VRR? Is this even possible on any of the docks?
  • Gigabit Ethernet at minimum
  • A few USB-A/C for dongles/USB hard drives

Any one have any great luck with one?
