If you’re looking for a premium speaker, you may wonder what ARC does on a TV. Learning about HDMI-ARC connections ensures you get the best sound quality from an advanced soundbar or HDMI TV. The HDMI-ARC port simplifies your entertainment center by eliminating your setup’s composite audio or optical cables. So, if you want to know what HDMI ARC means, read this guide.
Learning how to make your sound louder often involves changing your AV receiver and revising your cable management. Using an ARC-capable HDMI input is an integral part of how to make all speakers work on surround sound. Additionally, you can learn how to control a soundbar with a TV remote control once your AV equipment utilizes an ARC HDMI connection.
You shouldn’t invest in a new ultra-high-speed HDMI cable for ARC or eARC ports if your current HDMI cable is newer than four years old.
Consider investigating HDMI vs. Bluetooth for a soundbar if you want access to high-quality audio formats like Dolby Digital and Dolby Atmos. Unless you use HDMI 2.1, the results might surprise you.
Introduced alongside the HDMI 1.4 standard, ARC (Audio Returned Channel) allows for two-way communication between your connected sound system and TV with a single HDMI cable. An ARC-compatible audio system only needs an HDMI cable, and you no longer need additional audio connections like components, composite, or optical audio cables.
In addition to simplifying your cable management, you can control your entire entertainment setup with a single remote control.
As the HDMI 2.1 standard hit the market in 2018, an enhanced audio return channel (eARC) launched alongside it.
If your audio device predates HDMI 1.4, it likely will not work with ARC or eARC devices.
Enhanced audio return channel (eARC) launched alongside HDMI 2.1, an upgrade from the HDMI 1.4 standard. HDMI 2.1 supports higher bitrates than HDMI 1.4 for higher resolutions, framerates, and automatic modes for video game consoles.
ARC’s lower-quality audio capabilities prevent users from accessing modern audio technology like Dolby Atmos and other uncompressed audio signals. Thanks to eARC, users can enjoy full-resolution channels of audio from current Blu-ray players and game consoles.
