LG OLED B3 65" vs Samsung QN90C 65" (4K Neo QLED)
The Verdict
LG's B3 OLED delivers exceptional contrast and perfect blacks at an attractive $1299 price point, with 600 nits peak brightness and excellent gaming performance (7ms input lag). Samsung's QN90C Neo QLED counters with dramatically superior brightness,2000 nits peak,making it superior for bright rooms, plus superior audio (60W vs 20W), faster gaming response (6ms), and Wi-Fi 6E connectivity. However, QN90C's $500 premium and heavier build feel less justified given OLED's superior color accuracy and infinite contrast ratio. For dark room viewing or gaming-focused setups, LG's B3 represents outstanding value. Those prioritizing brightness, sports content, or gaming at the absolute highest levels should consider Samsung, though the price differential is significant. LG B3 edges ahead overall for most consumers seeking best-in-class picture quality at a reasonable price.
