HDIM Cable and ARC: Everything You Need to Know


If you have recently purchased a new television or audio system, you might have come across the term ARC (Audio Return Channel). ARC allows you to send audio from your TV to an external sound system, eliminating the need for additional cables connecting your devices. One of the fundamental components required for ARC to function is an HDMI cable. However, not all HDMI cables are created equal when it comes to ARC compatibility. In this article, we will delve into the world of HDMI cables and explore whether any HDMI cable works for ARC.

What is ARC?

Audio Return Channel, commonly referred to as ARC, is a feature available in certain HDMI-equipped televisions and sound systems. Traditional setups require a separate optical or analog audio cable to connect your TV to a home theater system or soundbar. However, with ARC, the HDMI cable you use to connect your devices facilitates both audio and video transmission, making it a convenient option for many users.

Understanding HDMI Cables:

HDMI (High-Definition Multimedia Interface) cables are the standard for transmitting high-quality audio and video signals between devices. They are widely used and come in various versions, ranging from HDMI 1.0 to the latest HDMI 2.1. Each new version brings advancements in capabilities and features, such as higher resolutions, increased refresh rates, and enhanced audio support.

The Different HDMI Cable Versions Explained:

To better understand the compatibility of HDMI cables with ARC, it is crucial to comprehend the different HDMI versions available. HDMI 1.0 was the first iteration, providing basic audio and video transmission. Over the years, subsequent versions have been introduced, each offering improvements and additional features.

HDMI 1.4 brought about the introduction of ARC. It allowed users to transmit audio from their TV back to the sound system through the same HDMI cable, simplifying connections. However, it is important to note that not all HDMI 1.4 cables have ARC functionality, as it is an optional feature in this version.

HDMI vs. ARC: Is There a Difference?

Many people often confuse HDMI with ARC, assuming they are the same thing. However, there is a difference between HDMI and ARC.

HDMI is the connection type that allows both audio and video to be transmitted between devices. It provides high-quality signals, supports multiple audio formats, and is backward compatible with older HDMI versions.

On the other hand, ARC is a feature that harnesses the capabilities of HDMI cables. It specifically enables audio to be sent from a TV back to a sound system using the same HDMI cable. ARC simplifies cable management, reducing the number of cables required in your setup.

ARC Compatibility: Factors to Consider:

While HDMI cables with ARC support simplify audio connections, not all cables guarantee compatibility. Here are a few factors to consider regarding ARC compatibility:

1. HDMI Version: As mentioned earlier, ARC was introduced with HDMI version 1.4. Therefore, it is imperative to ensure that both your TV and sound system support HDMI 1.4 or later versions.

2. ARC Support: Confirm that your TV and audio system explicitly mention ARC compatibility. Some devices might have HDMI ports, but not all of them necessarily support ARC.

3. Enabled ARC Setting: In addition to having ARC-compatible devices, it is essential to enable the ARC feature in your TV's settings. Manufacturers often have different names for this setting, such as 'HDMI-CEC,' 'Anynet+,' or 'Bravia Sync.'

4. High-Speed HDMI Cables: To ensure seamless ARC functionality, it is generally recommended to use high-speed HDMI cables. These cables meet certain performance standards and have sufficient bandwidth to handle the audio transmission.

Common Misconceptions about HDMI Cables and ARC:

When it comes to HDMI cables and ARC compatibility, there are several misconceptions that need debunking. Let's address some of the common myths:

1. All HDMI Cables are the Same: This is not true. While all HDMI cables have the same physical connectors, they come in different versions and consequently offer different capabilities. Older HDMI versions may lack ARC support or higher bandwidth required for certain audio formats.

2. Expensive HDMI Cables are Always Better: Price does not always indicate superior performance. An expensive HDMI cable does not necessarily guarantee better ARC compatibility or higher audio and video quality. It is essential to choose a cable that meets the necessary specifications for your specific setup.

3. ARC Works on Any HDMI Cable: While HDMI cables with ARC functionality ensure seamless audio transmission, not all HDMI cables support ARC. If your cable does not explicitly mention ARC, it is likely that it does not support the feature, regardless of its version.

Selecting the Right HDMI Cable for ARC:

To make the most of ARC functionality, it is vital to select an HDMI cable that meets the necessary requirements. Here are a few key points to consider:

1. HDMI 1.4 or Later: Choose an HDMI cable that supports HDMI 1.4 or later versions to ensure ARC compatibility.

2. Certified High-Speed HDMI: Look for cables that are certified as 'High Speed.' These cables guarantee sufficient bandwidth for audio transmission and support higher-quality video formats.

3. Length: While HDMI cables can be several meters long, longer cables may experience signal degradation. To maintain optimal performance, select an appropriate cable length for your specific setup.

4. Quality and Brand: Opt for cables from reputable brands known for their quality and reliability. Cables from trusted manufacturers are more likely to offer robust ARC support.


In conclusion, not every HDMI cable works for ARC. Only HDMI cables that support HDMI 1.4 or later versions, explicitly mention ARC compatibility, and meet the necessary performance standards can ensure seamless audio transmission. It is crucial to consider these factors while selecting an HDMI cable to maximize the ARC functionality in your audio setup. Remember, a reliable HDMI cable is a key component in achieving high-quality audio and video experiences.
