Comment on Any hints on how to connect the steam deck to the tv

This may help you for the wireless option; but it may difficult to setup on the deck due to the immutable filesystem: miraclecast allows you to use a linux device as a miracast client. Basically if you can cast your phone to the tv, you can use miraclecast to cast the deck’s screen, most likely though you are gonna get a lot of latency.
