A:Answer Hi there,
Thank you for considering this TV for your gaming! The TU690T has 2 HDMI ports that each support HDR10+ and Auto Low Latency Mode (ALLM/Auto Game Mode). The “HDMI In 2” port further supports eARC.
However, if you are looking to game at 4K@120fps (FRL), take a look at our 85” CU8000 Series and above.
