I Bet You Have No Idea What HDMI ARC is and its The Coolest Thing Your Not Using

I stumbled across this on a lazy Sunday morning reading this article on my Ipad, (yes newspapers are dead  as far as I am concerned) and before I had got half way through the article I rushed downstairs in my not so flattering dressing gown to check if my TV had one. Eureka it does but is the sound bar compatible ? I will tell you at the end. If I had no idea that this even existed I am sure that not many people will have so I just had to share this article from the nice people at Digital Trends

If you’re the owner of a newer HDTV, A/V receiver, sound bar, or home theater in a box, you may have noticed (and then promptly forgotten) a little symbol on one of the device’s HDMI inputs that says “ARC” or “HDMI ARC.” What does this mean? Hint: It has nothing to do with the reactor that powers Ironman’s suits.

ARC stands for Audio Return Channel, which is a little-understood protocol that started showing up on HDMI-equipped devices a few years back. Today, it is increasingly common. The technology is especially useful and has the potential to significantly simplify home entertainment systems. Unfortunately, few know it even exists, much less what it can do. Here, we’ll go over the basics of ARC so you can put its powers to work for you.#

The power of HDMI ARC

ARC can simplify your home theater system in two important ways. The first, and perhaps most useful feature HDMI ARC brings to the table is the ability to use one remote for all of your connected devices’ most common functions.

The most common example is for users who have added a soundbar (maybe one of our favorites?), home theater in a box (HTIB), or other secondary audio device to their TV. As long as both devices are equipped with ARC, simply connecting the HDMI cable to both devices’ ARC HDMI port will often allow for control of power, volume, and other features from your TV remote. In some cases, it will also simply transfer your TV audio to the unit automatically without having to deactivate the TV’s on-board speakers.


This feature is extremely useful for those who connect gaming consoles, Blu-ray players, set-top boxes, and other devices directly to the TV rather than an audio receiver. It allows for significantly better audio performance for all of your content than what you’ll get from a TV alone, but without having to think about the audio device.

Alternatively, ARC is also handy for other outboard components like streaming devices. Plugging a Google Chromecast into your TV’s ARC port, for instance, may allow you to automatically switch sources or even turn on your TV when you click the cast icon on your phone or tablet. You may find similar results with other components as well, including Blu-ray players.

If you are still wondering if my TV had the HDMI Arc port on then YES it did, I changed over the connections straight away and tried it, works a treat sound quality improved with the use of a single remote, perfect
