Troubleshooting HDMI devices with CEC

CEC (Consumer Electronics Control) is an HDMI feature that allows you to command and control other CEC enabled devices that are connected through HDMI, without user intervention.

Using Harmony with CEC devices

The CEC auto power and input feature can sometimes conflict with Harmony's ability to also power on and change inputs and can be safely disabled.

Different manufacturers have different names for CEC, each with slightly different capabilities. If you find your devices are powering on or off, or changing inputs incorrectly with Harmony, you may need to disabling various features under your CEC settings. Most manufacturers use their own unique name for CEC.
