Verdict: The LG OLED65C5 clearly leads with a brighter OLED‑Evo panel (≈800 nits vs ≈540 nits per RTINGS) and a newer α9 Gen 6 processor that improves AI upscaling and gaming latency (per Tom’s Hardware). While the C4 still offers true‑black performance and lower cost on the used market, its older panel and processor lag behind in bright‑room performance. For most buyers seeking the best picture and gaming experience, the C5 is the superior choice.

Winner: LG OLED65C5

LG OLED48C4: 7/10

LG OLED65C5: 8.5/10
