ARC vs eARC: What’s the Difference?

HDMI ARC vs HDMI eARC and the white background

While ARC stands for Audio Return Channel, its successor, eARC, stands for Enhanced Audio Return Channel. 

Both ARC and eARC are used to connect audio devices to displays. Their main difference lies in how much data they can transmit and how fast it takes them to do so. 

eARC, the updated version of ARC, can transmit much more data than ARC, allowing it to support higher-quality sound. Remember, one device’s sound is transmitted to another via data, with low-quality sound requiring less data transmission and high-quality sound requiring more. 

Check out the table below for a more detailed comparison between these two formats. 

You can connect your ARC soundbar/amplifier to an eARC projector, but bear in mind that you may not have the highest quality sound due to the ARC’s data transmission limitations

So, if you want to have the best sound quality possible, it’s best to ensure all devices are eARC-compatible.

Step 3: Now it’s time to connect your soundbar to your projector. If you’re setting up an eARC connection, use a 2.1 HDMI cable. Otherwise, you’ll need at least a 1.4 HDMI cable to create an ARC connection. 

Plug one end of your HDMI cable into the soundbar’s HDMI ARC/eARC port. 

Then, connect the other end of the same HDMI cable to the projector’s HDMI ARC/eARC port. 

More often than not, only one of a projector’s HDMI ports will support ARC/eARC, so be sure to connect your HDMI cable to the correct port.
