A:Answer Hi,
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 U7900 has 2 HDMI ports, both of which support HDR10+ and Auto Low Latency Mode (Auto Game Mode). HDMI port #2 further supports eARC. If you’re looking for a TV capable of 4K@120Hz, please consider a step up to the 55-85” Q8F TV, which supports this feature in all HDMI ports.
