My Samsung has this option, my Sony does not, as best as I can tell:
Not sure it would have helped you regardless but figured I’d mention it nonetheless. It’s interesting to see how very differently each company handles the CEC “standard.” Every recipe of various AV ingredients seems to have different results. When CEC works, it’s great (as this new feature attests.) It makes it easier to use easy remotes. But it can also be inconsistent across brands and TV models, and when it doesn’t work, it can be quite frustrating.
I’m really glad to see the Channels team forging ahead and making the best out of CEC, even though it works differently on different TV’s. That innovative and experimental spirit is what’ll keep me as a Channels customer for life.
