A:Answer With HDMI 2.1 being such a complex topic, we feel it’s clearer to highlight the specific features supported by each TV model. The Q60C has 3 HDMI ports, all of which support HDR10+ and Auto Low Latency Mode (Auto Game Mode). The “HDMI In 2” port further supports eARC. If you’re looking for a TV capable of 4K@120Hz, please consider a step up to the Q70C TV, which supports this feature in all HDMI ports.
