Is the TVs HDMI CEC enabled?
Some manufacturers call it differently
Well the streamers (android tv), that are connected to the different TVs can control the streamer but also the TV which let’s me believe CEC is activated.
Just to make sure the stuff I bought, is the same as yours
This is what you bought ?
Yes, the same hdmi pcb
So basically it isn’t the hw. Now would you be so kind as to make some photos what you connected to what ?
I went through it multiple times but maybe you can show in your environment to make sure.
