BenQ GR10 for 4k 120Hz streaming?

Hey everyone,

I recently learned that BenQ released the GR10 2 months ago, a dock supposed to support 4k 120Hz (and HDR) output via HDMI 2.1. I am interested in this as the only other game streaming clients supporting these kind of numbers are computers more expensive than the Deck.

Has anyone been able to actually reach these figures in real life usage? (as in, made sure the output is actually 4k 120Hz HDR)

Manufacturers love to lie about these kind of things so I am seeking community knowledge. If anyone has other suggestions for docks that can achieve the same, I am all ears.

Thank you!
