A:Answer HDMI 2 on the LG LG 65 Inch Class QNED80T Series 4K QNED TV with webOS 24, Model # 65QNED80TUC is an HDMI eARC port so you can connect it to a soundbar with an HDMI ARC port using an HDMI cable.
To take advantage of eARC, you’ll need a TV and a soundbar or receiver that support this feature. You’ll also need an HDMI cable that’s capable of transmitting eARC signals. Not all HDMI cables are created equal, so make sure to choose one that’s specifically designed for eARC.
eARC, or enhanced Audio Return Channel, is a feature that allows for the transmission of high-quality audio signals from a TV to a soundbar or home theater system through an HDMI connection. Unlike ARC (Audio Return Channel), which has limited bandwidth and can only support up to 5.1 channels of audio, eARC can support up to 8 channels of audio, including Dolby Atmos® and DTS:X.
It’s also worth noting that eARC may not work with all devices, such as older soundbars or home theater systems that do not support eARC. In these cases, you may need to use a different type of audio connection, such as optical audio or analog audio. However, if you have a newer TV and soundbar or home theater system that both support eARC, you should be able to use eARC without any issues...^Ivan.
