A:AnswerHi Bob, 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 QN800A are capable of Auto Low Latency Mode (ALLM), Dynamic Metadata (HDR10+), Variable Refresh Rate (VRR), High Frame Rate (HFR), 4K@120Hz (All HDMI), as well as 8K@60Hz. HDMI port 3 offers Enhanced Audio Return Channel (eARC). ^Val
A:AnswerGrapevineMike - The QN800A comes with a 2.5 meter One Connect cable and a 0.3 meter to use when you attach the Slim One Connect Box to the back of the TV. A longer version is not available currently. ^Gina
