Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your TV and other CEC-compatible home entertainment
components to control one other in various ways. First, the CEC-compatible devices must “discover” one
another and report their capabilities. After this, one device can control another according to the
features you enable. For example, playing a disc on a Blu-ray player could switch the TV to the Blu-ray
player’s input. Or, powering off the TV could also power off the Blu-ray player and the home theater
receiver.
Discovering connected CEC devices
To discover CEC devices:
1. Make sure that your CEC-compatible components are connected to the TV with a suitable high-
speed HDMI cable that supports HDMI ARC and CEC control.
2. Turn on each component and make sure all components have CEC enabled.
Tip: Some manufacturers have their own branded names for CEC functionality, so you might
need to read the product documentation to correctly identify the CEC features of the device.
3. On the TV’s Home screen menu, navigate to Settings > Control other devices (CEC) > Search for
CEC devices, and then press OK to start the discovery process.
When finished, the TV displays a list of CEC devices that are connected to each HDMI input, as well as
any devices that had previously been connected. The TV remembers the names of multiple CEC devices
even when they are no longer connected. If the list is longer than the allowed space, press  to see a
complete list in a scrollable window.
Enabling HDMI ARC
HDMI ARC is the audio return channel that is available on one of the TV’s HDMI ports. The audio return
channel enables you to send a Dolby Digital audio signal back to a home theater receiver that is also
sending an audio and video signal into the TV. Using HDMI ARC reduces the number of cables needed
and optionally lets you control the volume and mute state of the receiver by enabling system audio
control.
HDMI ARC is disabled by default. To enable HDMI ARC, in the Home screen menu, navigate to Settings >
Control other devices (CEC), and then highlight HDMI ARC. Press OK to check the adjacent check box.
Enabling system audio control
System audio control enables the TV remote control to change the volume and mute state of an
amplifier or sound bar connected through HDMI, and to display the external device’s volume and mute
status in the TV’s on-screen display.
