I have a 2015 4k Samsung TV, and I cannot get the HDMI CEC feature to work for me for anything.
I have CEC enabled in the Samsung menu, and it finds my Mi Box just fine, and then from there I can control the Mi Box with my Samsung remote and all, but that's not what I want. From there, I want to be able to turn on my TV with the Mi Box remote. I'm not worried about turning it off with the remote (I've heard that feature doesn't work at the moment), but I can't even get it to turn on at all. Every time I do start up the TV with my Samsung remote (my only current option), CEC doesn't work until I go to the menu, search for the device, and manually connect it. I can then once again control the Mi Box with my Samsung remote, but still cannot turn the TV on when it's off.
Any help would be greatly appreciated. I am completely confused with why this simple feature just doesn't want to work for me.
