  1. HDMI ARC: What is it and Why You  Should Care?  If you buy a new TV or soundbar, you might have come across                           the new label about “ARC” while setting up the HDMI adapters.                       That indicates one of the best features which saves your                     money, reduces cable web and makes your set up more                     simplified.      What Is ARC?  Ever since the HDMI 1.4 was introduced in the market, ARC is                         available on TVs, soundbars, and other gadgets. It is a protocol                       which offers two-way communication between devices over a                 single HDMI connection. This port lets you use HDMI as both                       an input and an audio output.    1​​

  2. It came in 2009 and became a common standard. Majorly you                       would find it with all types of TVs, soundbars, and receivers.                       All the devices which support HDMI 1.4 would support ARC.  Things You Can Do With ARC:  It provides a two-way flow of sound means that you can use it                           for things which require extra cables.  1. First and foremost, you will be able to connect your audio                       system with a single ​HDMI cable​. For that, connect your soundbar to the TV with the ARC-capable port. After that,                                         you can use it for every device that connects with TV. It                         includes Blu-ray players, game consoles, and other               devices. Plus, it does all of these through the TV itself.                       You do not require a separate audio receiver.  2. You can run the connections mentioned above through                 the soundbar itself. It allows you to shift the multiple                     HDMI connections from the TV to the soundbar without                   any additional setup. In some cases when your TV is wall                       mounted and you can’t access all of the HDMI ports or                       simply want a clean look which includes fewer cables, the                     arc capable ports are perfect. It requires lesser cable                   installations.  2​

  3. 3. ARC system also comes handy when you connect the TV                     with a soundbar or speaker system. You can also use the                       ARC connection to deliver audio from the TV to your                     speakers. Without the HDMI Arc, you will need to go into                       the TV settings to activate the “Receivers” or “External                   Speakers”. But with the ARC, it automatically sends the                   TV’s audio to whatever external device is connected with                   it.  4. With ARC supported system you can deliver sound to                   your soundbar without any other connector with a                 dedicated audio cable.  5. With HDMI-CEC (Consumer Electronics Control) like             Blu-ray players or satellite boxes, you can use ARC to                     reduce both the number of cables used and the number           of controls needed for your system.            How To Setup:  To set up ARC completely with the system, you can follow the                         steps given in the guidelines below. Depending on the model                     and manufacturer, it might take some time to activate it.    3​

  4. Determine   the   ARC   port   on   your   system.   Most   TV   manufacturers offer ARC output over HDMI port instead of all                     three or four port on the set. Mostly they try to indicate it                           with labels. If ​HDMI adapters ports don’t have proper labeling, check the TV manual. It will help you navigate to the HDMI                                             ARC that you can use.    Activate the ARC output on the TV to start leveraging it. You                         can find this feature in the settings menu under audio. In                       many TVs, this feature auto-detect devices with ARC capacity.                   While in others you need to turn on the feature manually.    One thing to keep in mind while plugging in your stuff is that                           ARC-enabled port should be there with your external audio                   device.    Paradoxically…  Even   our   brand-new   iPhone   model   would   have   some   drawbacks. Just like that, the simplicity of ARC and audio over                       HDMI is viable, but it has some disadvantages as well. The                       main aim behind designing this stuff was to replace S/PDIF                     4​

  5. digital audio outputs. Thus, it supports each and every audio                     format that wouldn’t normally pass through S/PDIF. For                 instance, Dolby Digital, DTS and PCM audio. It can handle TV’s                       regular two-channel audio and 5.1 surround sound without                 any troubles.    Even though it replaces the S/PDIF standard, it can’t send HD                       or high-bit-rate audio with high standards like Dolby Atmos                   and DTS:X. It can be little overwhelming as the downstream                     audio over HDMI can carry the signal without any obstacles.                     This is ARC related disadvantage only which is one of the                       major limitations of the ARC specifications.    Some TVs actually downgrade the audio output over ARC by                     converting everything to two-channel sound even if it                 originates as 5.1 audio. Depending on your TV model you might                       wind up with the lower sound quality even after using ARC. In                         this case, if you want, you can connect an extra audio cable or                           two which may cause more trouble for you but will be worth                         it.    5​

  6. The Power Of HDMI ARC  In the present scenario, many TVs dumb down and compress                     audio signals before passing them down to HDMI cables while                     others do support more channels. Dolby Atmos albeit uses a                     compressed codec like Dolby digital plus instead of Dolby True                     HD. Now that requires much bandwidth. But with ARC, you                     can send the original, full-resolution audio signal via HDMI                   cables.   Which   produces   the   best   sound   without   any   compromises.    This Article is Originally Posted here;  https://www.sfcable.com/blog/hdmi-arc-what-why-you-ca re    If you found this article useful, here are some other Articles                       that may be of interest.    Difference between an RCA, DVI and HDMI cable  FAQs About HDMI Technology Answered  A Guided Tour on HDMI Cables, Their Types, and  Functionalities  6​
