You’re projector’s specs boasted two 5-Watt speakers and promised that their sound could be heard from several feet away. However, when you connected it to your laptop to watch a movie, you could barely hear its soundtrack, let alone the audio.
Alternatively, maybe you found that the projector you bought didn’t have built-in speakers at all! Many high-quality projectors, like JVC units, don’t have speakers as they’re meant to be connected to a sound system.
You’re realizing you may need to connect your projector to an external audio device, and that a soundbar may be the best option since it produces high-quality sound and is easy to connect.
However, many modern soundbars use HDMI ARC or eARC, but do projectors even support this feature?
Yes, many projector models are ARC/eARC compatible. That said, not all projectors will support ARC/eARC.

ARC vs eARC: What’s the Difference?
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.
