Steam Deck + Steam Dock question

you mean on the tv - i don't know but i'd be interested in the answer

If it acts like a normal pc, i can't see why it shouldn't?

Sure. And you can also use pads connected to the Deck via Bluetooth.

I mean, it's just 2 USBs and 1 HDMI/DP so it's not even that demanding. I suppose that even some basic third party hub with the needed ports would work just fine.

We played Dysmantle on it while connected to a TV, one controller having cabled and one bluetooth connection if I remember correctly.
It's just a mobile PC with the dock on hand :)
