A:Answer Hi Talia! You can definitely play the Xbox Series X on the TU8300. Auto Low Latency Mode (ALLM/Auto Game Mode) is available on all 3 HDMI ports for this series. The “HDMI In 2” port additionally supports eARC.
However, if you are looking to game at 4K@120fps (FRL), take a look at the Samsung QLED Q70T Series and up. These series in 55" and larger offer 4K@120fps on HDMI 4, as well as have Variable Refresh Rate (VRR) and FreeSync. If we can further help, please call us at 1-800-SAMSUNG.
