What is CEC?
For those not familiar CEC or Consumer Electronics Control is the ability to control another device over HDMI. There are quite a few different controls that work with CEC although not every manufacture supports this protocol the same way or has their own version of it.
For the purpose of Cisco’s TelePresence endpoints CEC mode is implemented in TC software as a way to control power management of displays attached to either codecs such as the SX20 as their primary display or in the case of MX series extended displays.
Enabling CEC mode
Turning on CEC mode is pretty simple. Its just a matter of accessing the web UI and enabling the feature.
This feature, because of the variation on consumer displays may work but it carries no guarantee that it will. With new displays coming on and off the market all the time its really up to the display manufactures to support this protocol in a standard fashion which depending on the model may or may not happen.
So if you decide to head down the consumer grade display road make sure that the display will work with your AV gear and supports the protocols you need it to. That 80 incher at Costco may look good but it may not work for your conference room.
