Axiom Home Page Forums General Discussion Home Theater HDMI CEC: does it work?

The answer is: it depends.

For devices from the same manufacturer and the same model year. It works pretty well.

As those two factors diverge, so does the compatibility. Even if the design specs say that shouldn't be the case.

For power on/off, your chances of it working are pretty good. But still the only way to know is to check the manuals of the components to find out how to enable CEC, and the what options it supports. Then try it.
