Hi Liam, HDMI 2.1 is a complicated matter. The TU6980 has eArc functionality in HDMI port 2, which is part of the HDMI 2.1 feature set. Those looking for ALLM, 4K @ 120fps, and other video game oriented HDMI 2.1 standards would be better suited with the Q70T shown here: https://www.bestbuy.com/site/samsung-75-class-q70t-series-qled-4k-uhd-smart-tizen-tv/6402404.p?skuId=6402404 Thanks, ^Scott
