The 2025 mainstream LG OLED keeps the same connectivity profile as the C4 — four full HDMI 2.1 ports at 48 Gbps with 4K@144Hz, VRR and ALLM, eARC on HDMI 2 — and adds the new Alpha 9 Gen 8 processor. Three USB-A 2.0 ports, optical, 10/100 Ethernet, RF antenna and the LG-style 3.5mm AV/headphone combo jack live on the rear-left bay. There is still no DisplayPort and no USB-C input.
