A:Answer This TV supports powerful HDMI features, including eARC and Motion Rate 240 with MEMC Frame Insertion, ensuring not only amazingly fast gaming response, but also a great cinematic picture that gamers demand. For this 58S5F, the HDMI ports can support up to 4K/60Hz. This model does not support HDMI 2.1. Hope this helps! Thank you, TCL Customer Support
