Setup required to DIRECT play TRUE HD atmos or atleast DD+

Hey, thanks for getting back to me. Sounds about right, got the shield pro and will also hopefully just hook it up to my router for faster speed. I’m ranging from 25ft to possibly 50, waiting on my AV guy to come but I found these cables by RUIPRO that people have been saying work well for 40ft plus hdmi 2.1 etc. My plan is to setup everything up without any wall mounting and watch a few movies w 2-3 hdmi cable brands to test for steady true hd atmos with no drops etc.
