The HDMI ARC port on the LG 4K UHD HDR Smart LED TV - 43" Class (42.5" Diag), Model # 43UJ6200 is an input. It is labeled as HDMI IN?ARC meaning that it supports ARC functionality. ARC or Audio Return Channel is an HDMI feature that is built into many TVs, receivers, and sound bars. It uses a single HDMI connection to send audio from a TV to the Sound Bar or AV Receiver and that same HDMI cable can send Audio back to the TV from a Sound Bar or AV Receiver provided those devices also support ARC functionality and have an HDMI ARC port. It also allows you to use one remote to turn on everything in your system...^IFV
