LG B4 55" vs LG OLED C2 55" (Evo)
The Verdict
Both deliver exceptional OLED picture quality at 55 inches, but with distinct strengths. LG B4 features the newer α8 Gen 7 processor, superior brightness (1100 nits vs 800), and webOS 24 with enhanced AI capabilities,ideal for bright rooms and demanding viewers. Meanwhile, the C2 Evo remains a solid performer with true WOLED technology, faster Wi-Fi 6 connectivity, and slimmer design (1.6-inch bezel). Gaming lag is minimal on both (1ms vs 6ms). Audio capabilities are comparable with Dolby Atmos support. Where B4 excels is peak brightness and latest software, making it better for HDR content and gaming. C2 Evo justifies its $100 premium primarily through build quality and design elegance rather than performance gains. For most buyers, the B4's superior brightness, newer processor, and identical gaming responsiveness deliver better value and future-proofing at a lower price point.
