LG B4 55" vs LG QNED80 55"
The Verdict
LG's B4 OLED and QNED80 represent different value propositions at 55 inches. Picture quality heavily favors the B4, which delivers perfect blacks, infinite contrast, and superior color accuracy typical of OLED technology,critical for cinephiles and dark room viewing. Its 1100-nit peak brightness with Dolby Vision IQ processing surpasses the QNED80's 700-nit performance, though the QNED's quantum dot technology provides brighter overall presentation for bright rooms. Gaming performance slightly advantages the B4 with 1ms input lag versus 10ms, though both support VRR and ALLM. Audio differs notably: B4 offers 40W with Dolby Atmos versus QNED80's 20W without spatial audio. The QNED80 weighs 30% less and costs $500 less, making it attractive for budget-conscious buyers. Both share webOS 24 and comprehensive smart features. For picture quality and gaming, B4 dominates; for value and lighter installation, QNED80 appeals. Recommend B4 if display excellence justifies premium pricing, otherwise QNED80 delivers solid performance at budget-friendly cost.
