LG B4 55" vs LG OLED C3 65" (Evo)
The Verdict
Both are premium OLED TVs, but they serve different priorities. LG B4 offers exceptional value at 55 inches with superior brightness (1100 nits vs 900), making it ideal for brighter rooms and a smaller viewing space. It includes Filmmaker Mode and delivers 1ms input lag for competitive gaming. LG C3 Evo justifies its $600 premium through a larger 65-inch screen, more advanced OLED Evo panel technology, Wi-Fi 6 connectivity, and webOS 24 vs 23. However, C3's 6ms input lag is marginally higher, and 200 nits less brightness could disappoint in well-lit environments. At 55 inches, the B4 provides outstanding performance and value for most buyers; upgrade to the C3 only if you need the larger size and can justify the substantial price difference. For most living rooms, the B4 is the smarter choice.
