so looking at this the problem seems kinda basic.
You have 2 TV's called Smart TV and it looks like you are using teh Denon AVR in both rooms? can you please confirm? It looks like they connected the HDMI 1 and HMDI 4 in the living room TV both to the zone 1 and zone 2 outputs of the denon AVR.
Since I am not there to trace the wires - i need you to. Can you please tell me the following:
Denon Zone 1 output is connect to which room? And which HDMI on the TV?
Denon Zone 2 output is connect to which room? and which DHMI on the TV?
If you can trace this, I can fix it in composer. but it totally makes sense what is going on.
Your dealer also didn't enable driver auto update - so I enabled that for you.
If you tell me how this is wired I will ask for payment via paypal https://paypal.me/ghctim or venmo @gchtim and it will be $30
