No, it does not have HDMI 2.1. Only the 6 series and up have HDMI 2.1. This TV also doesn't have 120Hz refresh rate either. Not the best for gaming.
Sorry, there was a problem. Please try again later.TCLs 5 Series supports powerful new HDMI features, including eARC and an Auto Game Mode assuring not only fast gaming response, but also a great cinematic picture that gamers demand! Hope this helps! Thank you, TCL Customer Support
