A:Answer Hi Thefoo, Thank you for considering the QN90A for your gaming needs. It is equipped with 4 HDMI ports, all of which support Auto Low Latency Mode (ALLM), Dynamic Metadata (HDR10+), and Variable Refresh Rate (VRR). High Frame Rate (HFR) 4K@120Hz is supported in “HDMI In 4”. The other ports will still give you Game Mode, but will not be 4K@120Hz. The “HDMI In 3” port further supports eARC. ^Val
