Sorry, there was a problem. Please try again later.All four of the HDMI inputs on the LG 48-inch Class LG OLED AI B5 4K Smart TV 2025, Model # OLED48B5PUA, are HDMI 2.1 ports, so they all support 4K @ 120 Hz. They support full 4K gaming at 120Hz, along with features like VRR (Variable Refresh Rate, up to 120 Hz) and ALLM (Auto Low-Latency Mode). HDMI 3 is specifically designated for eARC (enhanced Audio Return Channel)...^Ivan.
