HDMI 2.1 ports allow for higher resolutions at higher frame rates than before. With With HDMI 2.1, you can get 4K at 120Hz, 8K at 60Hz, and right up to 10K resolution for industrial and commercial applications. The LG NanoCell 85 Series 2020 55 inch Class 4K Smart UHD NanoCell TV w/ AI ThinQ® (54.6'' Diag), Model # 55NANO85UNA features two HDMI 2.1 ports (HDMI 2 and HDMI 4). Your source has to be a 4K @ 120Hz signal and you will need an HDMI 2.1 cable...^IFV
