Modern TVs pass audio digitally out one of the HDMI inputs to an attached receiver. This feature is called ARC, and the enhanced version that can carry more than 2 channels of uncompressed digital audio is called eARC. If the new LG was made recently, it will support ARC and eARC, and you'll probably want a receiver that supports eARC. The RX-V4A handles both. If the LG can handle 4k@120Hz signals, save yourself some headache and grab a $15 8K HDMI cable for eARC. You'll be able to plug in 8K and 4K HDMI sources (game consoles?) to either the TV or receiver and enjoy 5.1 uncompressed audio. NOTE: The TV may have a digital out via something called Toslink or SPDIF. Don't bother with this. HDMI adds a feature called CEC which allows you to control the volume, power status, and inputs of the receiver using the TV remote. Toslink doesn't do this.
Sorry, there was a problem. Please try again later.
