Then you run out of HDMI inputs and have to get a switch and then deal with the problem of all the fake "4k" stuff around. Fun being into tech so much.
I encountered that problem a while ago so I have a 5 port HDMI switch.
Just installed a Harmony Ultimate One remote and paired it with Alexa and that works pretty well.
"Alexa - turn on Bluray" which
1. turns TV on and sets to HDMI1
2. Turns on AVR - sets it to DVD
3, Switches HDMI switch to position 2
I think the Harmony remote can do bluetooth also which (to get back slightly on topic) can then control my Firestick 4K (must check)
