HDMI ARC vs HDMI eARC: Are there any differences?

We all love the latest and greatest technology that comes out in the form of a new TV.

HDMI ARC and HDMI eARC are added in the later versions of the HDMI 2.1 specification.

Both these standards are meant to solve the same problem in the HDMI ecosystem.

However, there are some differences between these two standards.

In this blog, I will compare HDMI ARC vs HDMI eARC with all the details you need to know.

Let’s get started!

HDMI ARC vs HDMI eARC

What is HDMI ARC?

HDMI ARC is the acronym for Audio Return Channel, which transmits video and audio signals in one interface.

It does not convert analog or digital (digital) sound to another type but outputs the same signal via the HDMI connection.

When to use HDMI ARC?

Because the single interface transmits both video and audio signals, it is suitable for those who want to reduce the number of cables and those who want to switch between sounds because no separate cable has to be connected.

How to use HDMI ARC?

Connect the external device that supports “HDMI ARC” according to the instructions included with the device.

Connect your TV and other devices using an HDMI cable, then set your TV’s input source to display video from the external device.

You may need to use a separate remote control for this operation; check your TV’s instructions.

What is HDMI eARC?

This feature eliminates the need for a receiver that has an Audio Return Channel input.

In addition to this, HDMI eARC allows the TV to send audio to the receiver over the HDMI cable when the TV is in standby mode.

If you have a TV with this feature, the audio will not be cut out when you turn the TV off.

When to use HDMI eARC?

eARC stands for ‘Enhanced Audio Return Channel’ and is the newest technology to HDMI.

It’s great for your TV usage, but you will need a TV compatible with the technology to use it. 

If you have a TV compatible with eARC, you’ll benefit from having a quicker and easier way to get the sound from your TV to your soundbar.

It’s an excellent feature for people who have a lot of input on their TV.

There’s only one input needed for your TV and soundbar to communicate, so you can get rid of many wires and keep your room organized.

Pros and Cons of HDMI eARC

Here are the pros and Cons of HDMI eARC below:

Pros

• Better quality sound transmission due to the higher bandwidth of transmission and speed.
• Supports high bitrate modern Audio formats like Dolby Atmos, DTS:X, and lossless codecs like DTS HD Master, etc., for an Ultimate Audio experience.
• This technology can allow users to send audio from television back to a sound system, eliminating the need for a separate audio cable. 
• HDMI eARC can also send 4K video from the TV to the soundbar or sound system and 3D video.
• In addition, HDMI eARC is backward compatible with HDMI 1.4, which means that you can use it with both new and older HDMI devices.

Cons

• Does not work with any HDMI cables. It needs High-speed HDMI cables with Ethernet.
• Not all products support HDMI eARC. So, you need to check the HDMI eARC compatibility of your TV and Soundbar.

Pros and Cons of HDMI ARC

Here are the pros and cons of HDMI ARC below:

Pros

• It consumes less power compared to connecting a different audio system because it only uses the HDMI cable.
• It allows you to control multiple devices with a single remote.
• Requires one less remote control for controlling your devices, where you can change channels or volume by using the TV’s remote control instead
• It is an easy way to connect all your HDMI devices and enjoy them on a single TV.
• It reduces the number of cables needed to connect devices.

Cons

• HDMI ARC only supports video and audio via an HDMI cable, so you cannot enjoy them on a TV without an HDMI ARC port by using other types of connections.
• It requires additional setup time for each device.
• If the external device does not support an HDMI-ARC connection, you can only use your TV’s speaker to output audio.
• You cannot use other devices connected via HDMI cable simultaneously when connecting an external device that supports “HDMI-ARC.”

HDMI ARC vs HDMI eARC: Which is better?

HDMI ARC and HDMI eARC are similar in several ways.

However, a difference between the two technologies should be considered to eliminate confusion when making a purchase decision.

The main difference exists in the interoperability between devices supporting these technologies.

HDMI eARC replaces HDMI ARC, which uses the same technology but with an updated interface.

Although porting HDMI eARC into your system will be relatively easy, it’s important to remember that some older devices are not compatible with the new standard.

To ensure successful communication between your device and TV, you must upgrade them both to the latest version.

Is HDMI ARC the same as HDMI eARC?

HDMI ARC and HDMI eARC are the same things.

The HDMI ARC and HDMI eARC technology transmit audio to a home theatre receiver (HT) and streaming services like Amazon Music and YouTube and Netflix, and others. 

The ARC (Audio Return Channel) technology allows you to send the audio from your TV back to your home theatre receiver instead of using an optical cable.

The ARC technology was introduced in HDMI 1.4 and HDMI 2.0.
