If you are wondering what is CEC. CEC is a communications protocol built into the HDMI standard allowing CEC-enabled HDMI devices to exchange information and send/receive control messages. This allows a user to control more than one device using a single interface. For instance, CEC-capable devices such as DVD players or game consoles, or in our case industrial computers, are able to send a power signal to a connected display when the device is turned on, without any user interaction with the display itself.
