It also says turn on Control For HDMI Feture on TV

I don't know what is it.

 

But what I got when I googled it, is this

 

ARC is supposed to let you have one connection between your TV and whatever you use to create sound: a receiver or a sound bar. You send video to the TV with an HDMI cable, and that same HDMI cable sends audio from the TV back down the same cable.

think of it as a duplex connection through HDMI. the cable can handle signals in

both directions through both connections at the devices. can transport video/sound

through both directions send and receive. most cables are "rated" as single pass or

omni-directional.

HDMI 1.4 introduces a feature called ARC (Audio Return Channel).

 

ARC is an audio link meant to replace other cables between the TV and the A/V receiver or speaker system. This direction is used when the TV is the one that generates or receives the video stream instead of the other equipment. A typical case is the running of an app on a smart TV such as Netflix, but reproduction of audio is handled by the other equipment. Without ARC, the audio output from the TV needs to be routed by another cable, typically TOS-Link or coax, into the speaker system.

 

The other one probably refers to CEC.

 

Consumer Electronics Control (CEC) is an HDMI feature designed to allow the user to command and control up-to 15 CEC-enabled devices, that are connected through HDMI, by using only one of their remote controls (for example by controlling a television set, set-top box, and DVD player using only the remote control of the TV). CEC also allows for individual CEC-enabled devices to command and control each other without user intervention.

Audio Return Channel (if I remember correctly) It sends audio from whatever is connected to your tv back to the sound system.
