LG B4 55" vs LG QNED85 55"
The Verdict
Both 55-inch LG models deliver excellent value at their respective price points, but serve different audiences. Picture quality diverges significantly: the B4 OLED produces superior contrast with perfect blacks, 1100-nit peak brightness, and Dolby Vision IQ for exceptional HDR performance. The QNED85 relies on quantum dot LCD technology with 700 nits, offering vibrant colors and good HDR but lacking OLED's infinite contrast. Gaming performance favors the B4 with 1ms input lag versus QNED85's 7ms, crucial for competitive players. Audio output differs notably,B4's 40-watt 2.0 system with Dolby Atmos substantially outperforms QNED85's 20-watt setup. The QNED85 runs webOS 23 versus the B4's webOS 24, though both support major voice assistants. At $1199 versus $799, the B4 commands a 50% premium but delivers OLED's transformative picture quality and superior gaming responsiveness. The QNED85 represents stronger value for budget-conscious buyers prioritizing brightness and general-purpose viewing. For serious enthusiasts and gamers, the B4 justifies its cost; casual viewers find excellent performance in the QNED85.
