“The HDMI input that supports eARC does not support HDMI 2.1 and thus does not support 4K video at 120 Hz. So it seems to me that I need two HMDI cables between my AVR and the TV. One for the 120 Hz video and one for eARC. Is that correct?”

• It is recommended to connect audio systems to the HDMI eARC port, and external devices cable of 120Hz directly to one of the HDMI ports that supports it. Hope this helps! Thank you, TCL Customer Support
