“While looking at the 4 HDMI ports, only HDMI ports 3 and 4 say "4K @ 120Hz”. So does that mean HDMI ports 1 & 2 can’t display 4K @ 120Hz? Or are all 4 HDMI ports 4K @120Hz capable and ready?”

• Hi MizzGoku. HDMI 3 and HDMI 4 on the LG NanoCell 90 Series 2020 55 inch Class 4K Smart UHD NanoCell TV w/ AI ThinQ® (54.6'' Diag), Model # 55NANO90UNA are HDMI 2.1 ports that support HDMI 2.1 features so they will also support 4K @ 120Hz. HDMI 1 and HDMI 2 are not HDMI 2.1 ports so they only support 4K @ 60Hz....^IFV
