If you have had to deal with TV-related electronics in recent times, you might have noticed the ARC label. These labels can be found in the HDMI inputs and have some kind of meaning to them. Today, we try to understand what ARC is, what it does, and how to convert HDMI to HDMI ARC. 

What is HDMI ARC? 

The ARC in HDMI ARC stands for Audio Return Channel. This means that HDMI ARC is capable of interfacing audio between two audio channels. To have HDMI ARC running, it is necessary to have ARC capability on both sides. Ever since HDMI 1.4 came out, ARC has been available to PCs and TVs.

Different Types of HDMI

You have probably heard of HDMI a lot. But have you heard of all its types? Let’s take a look at the various types of HDMI and what they all do.

  1. HDMI Standard:
    This is the most common type of HDMI cable, and it is designed for standard home theater use. It supports 1080p video and up to 8-channel audio. This is the one that comes with most Laptops and computers.
  2. HDMI High-Speed
    This type of HDMI cable supports 1080p video. It also supports up to 8-channel audio, but it also supports 3D video and 4K resolution.

  6. HDMI with CEC
    This type of HDMI cable supports Consumer Electronics Control (CEC). Thich allows devices to be controlled with a single remote control. This feature was made a part of HDMI in 2005. It was made to control Blu-ray players or audio receivers with a single remote control. 

Is HDMI capable of sharing Audio? 

If you want to share audio using HDMI, it’s necessary to have HDMI ARC. In most modern devices, the HDMI version is higher than HDMI 1.4. Therefore, in most modern devices, HDMI IS capable of sharing audio. However, if your HDMI version is older than HDMI 1.4, you won’t be able to share audio with HDMI. 

One of the most common questions asked is, “How do I know if my cable is ARC?”. 

Most devices with an ARC port will come with a label on the ARC port that looks somewhat like this: <add an image please>

In the case of wires, HDMI wires with versions greater than 1.4 will have HDMI ARC. 

How to Convert HDMI to HDMI ARC ?

To be able to use HDMI ARC, you should have HDMI ARC ports and Capable HDMI wires. There are multiple ways to use these ports if you actually have them. But, if you don’t have these ports, there is not much you can do. So, If you don’t have HDMI ARC capable ports, you won’t be able to use HDMI ARC. But, if you have HDMI ARC ports on both ends, there is good news. You will be able to use HDMI ARC. The only thing that is possibly stopping you is the wire that you’re using to connect it. If you are using a wire that is not HDMI ARC capable, you won’t be able to use it. 

You might be asking the question, “Will a splitter not work?”. The problem with using a splitter with a port without ARC is that the Splitter is incapable of adding ARC to the port. For this, you’ll have to swap the entire port on your TV. And that proves to be a little more than a simple task.
