It's good, but meaningless at this point since no GPU makers incorporate CEC into their GPU ASICs and they have ignored CEC thus far. I suppose that might change with the next-gen GPUs and HDMI 2.1, but I'm not holding my breath. One of the issues with CEC is that it's not really implemented in a standardized fashion that makes things fully compatible/capable across different brands of electronics (Sony, Samsung, Vizio, etc.) as manufacturers use their own versions of it.

Are you sure? Afaik they just rebrand it, I've seen quite a bit of cross-brand CEC that works fine.

I know of some Sony stuff back then that refused to work with other brands (2010 maybe), but a guy on this forum said CEC in his newer Sony stuff worked fine cross-brand.
