“In my research TCL hasn't specified what cable will be needed for the HDMI port with eARC. Will a high bandwidth HDMI 2.1 cable be required to get the most out of this TV?”

• To support all the features of HDMI 2.1, including 8K support, high speed cables with Ethernet are needed. To support eARC, auto game mode and other features, the current high speed HDMI cables work just fine. Hope this helps! Thank you, TCL Customer Support
