We always hook our lap top into the HDMI input on back of TV. We bring a universal remote and HDMI cable and can then watch Netflix, Amazon Prime etc. etc.
If you have any problem just call maintenance and ask for an electrician to come to your cabin and help....they will.
We just used our Firestick on Navigator and the cabin remote gave us some problems but an electrician came and put a code into the cabin remote and it easily let us use it instead of our laptop.
Problems, just ask their very helpful and was told they do this all the time for guests.
