HDMI CEC (Consumer Electronics Control) is a feature that allows your HDMI connected devices to communicate with each other. The big benefit of CEC is that all your HDMI CEC connected devices can be controlled with one remote.
HDMI CEC is turned on by default on most TVs, but if you find that it is not working with your HDMI CEC compatible Zvox, the problem may be that CEC is turned off on the TV.
The table below shows the location of the CEC setting on most TV brands. It also shows what your TV's manufacturer calls CEC.
