Normally, you would need separate connections for audio input and output, but ARC allows audio to flow both ways through the same HDMI cable, making setup simpler and reducing clutter.
The significant advantage of ARC is that it allows your television to send audio signals back to your audio device without requiring additional cables. This feature is incredibly useful for enjoying high-quality sound from built-in television apps or broadcast audio.
Identifying an HDMI Cable that Supports ARC
Now that we’ve laid the groundwork, let’s explore different methods to determine if your HDMI cable supports ARC.
Check the Specifications of Your HDMI Cable
The most reliable way to confirm whether your HDMI cable supports ARC is to check its specifications. Almost all HDMI cables produced after 2009 include ARC support as part of the HDMI 1.4 and newer standards. If you bought your cable after this date, there’s a high likelihood it supports ARC.
Many manufacturers will explicitly mention ARC support on the packaging or product description. Look for terms such as:
- HDMI 1.4 or higher: ARC support was integrated starting from HDMI version 1.4.
- Audio Return Channel (ARC): Explicit mentions will confirm its capability.
For those with older cables, it’s unlikely to have ARC support if it is an HDMI 1.3 or earlier version.
Look for the HDMI Logo and Version Markings
Most HDMI cables will have the manufacturer’s logo and specifications printed on them. Here are some characteristics to look for:
1. HDMI Logo
Check for the official HDMI logo printed on the cable’s connectors. Cables that have the HDMI logo usually indicate they comply with HDMI standards.
2. Version Numbers
If you find version information printed on the cable, check if it says “HDMI 1.4” or “HDMI 2.0”. HDMI 1.4 introduced ARC, while HDIM 2.0 and beyond also maintain this feature.
Testing Your HDMI Setup
If you want to be more hands-on in determining whether your HDMI cable supports ARC, you can do some practical testing with your devices. Here’s how:
- Connect your HDMI Cable: Plug the cable into an HDMI ARC-enabled port on both your television and soundbar.
- Enable ARC Features: Go into your television’s audio settings and check if an option for ARC or eARC (Enhanced ARC, offering higher bandwidth) appears. If it does, your cable supports ARC.
If you’re able to return audio from your TV to the audio device without additional connections, congratulations! Your HDMI cable supports ARC.
