LG C4 65" vs LG OLED B3 65"
The Verdict
Both deliver excellent OLED picture quality in 65 inches, but diverge significantly in processing and brightness. LG C4 features the latest α9 Gen 7 AI processor with 1300 nits peak brightness versus B3's 600 nits, making it superior for bright rooms and delivering noticeably enhanced contrast with Dolby Vision IQ. Gaming performance heavily favors C4 with 1ms input lag compared to B3's 7ms, plus superior audio with 60W 2.2ch versus 20W 2.0ch. B3 compensates through lighter weight (41.7 lbs), more affordable pricing ($500 savings), and webOS 23 functionality that remains capable despite being one generation behind. For competitive gaming or bright living spaces, C4 justifies its premium. Budget-conscious buyers accepting lower brightness and gaming lag should choose B3.
