What is CEC?
CEC stands for Consumer Electronics Control and is a feature of HDMI that allows devices to control each other. For example, a CEC-enabled device such as Airtame can automatically power a CEC-enabled screen on and off.
Requirements
-
The Airtame screen needs to be running firmware version 4.1.0 or higher.
-
Ensure that CEC is enabled on your display (it is often disabled by default.)
Considerations
-
CEC is an industry-standard term and yet many screen manufacturers have renamed this feature, meaning CEC might be called something else on your display. If in doubt, check the user manual for your display.

CEC support varies among screen manufacturers. Not all displays support CEC and some only support certain functionality. For example, some displays will revert to Airtame as the default input source, but won’t automatically power off when idle. Other displays support CEC, but only on specific HDMI ports. Check the specifications within the display manufacturers’ manuals.
-
The Airtame device must be plugged directly into the display via HDMI to support CEC. If the Airtame device is plugged into an HDMI switch or video conferencing hardware, CEC will not work.
Use cases and benefits
-
CEC, used together with Sleep Schedule, enables remote screen management through Airtame Cloud. You can use Sleep Schedule to automatically power displays on and off at specific times of the day or after being idle for a specific amount of time. This saves on energy consumption as well as the time and effort otherwise wasted on manually turning screens on and off within corporate and educational environments.

When CEC is enabled, the Airtame device will turn a display on as soon as a presenter connects. The display will also revert back to Airtame as the main input source, even if changed the last time the display was used. This means less hassle when starting a meeting or class, as presenters don’t have to spend time changing the input source.
