Sorry, there was a problem. Please try again later.Thanks for asking! HDMI 2.1 is a somewhat complicated specification, so to better help our customers with their TV decision-making, we highlight the specific features supported by each TV model. All 4 HDMI ports on the QN900C are capable of Auto Low Latency Mode (ALLM), Dynamic Metadata (HDR10+), Variable Refresh Rate (VRR), 4K@120Hz (All HDMI), as well as 8K@120Hz. HDMI port 3 offers Enhanced Audio Return Channel (eARC). ~ Samsung Specialist
