Controlling other devices through CEC
Consumer Electronics Control (CEC) enables your TV and other CEC-compatible home
entertainment components to control one another 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.
Discover 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 are 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 > System > Control other
devices (CEC) and then select Search for CEC devices. Press OK to repeat the
discovery process, if necessary.
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.
Enable 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 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 > System > Control other devices (CEC), and then highlight HDMI
ARC. Press OK to enable or disable the feature.
Note: Enabling HDMI ARC also enables System audio control. After enabling HDMI ARC,
you can disable System audio control if you prefer.
