LG G4 77" vs LG OLED B3 65"
The Verdict
LG's flagship G4 77" OLED delivers superior brightness at 2100 nits with Micro Lens Array technology, making it exceptional for bright rooms and HDR content, while the B3 65" maxes out at 600 nits. Gaming performance favors the G4 with 1ms input lag versus the B3's 7ms, plus the G4 includes ALLM and VRR for competitive advantages. Audio capabilities differ substantially,the G4 provides 60W 4.2ch Dolby Atmos versus the B3's modest 20W 2.0ch system. Both feature webOS smart platforms and 120Hz refresh rates, though the G4 runs the newer webOS 24. Size and price create the primary trade-off: the G4's 77-inch immersion justifies its $3299 premium for enthusiasts seeking cutting-edge specifications, while the B3 65" at $1299 offers excellent OLED picture quality and smart features at half the price for budget-conscious buyers. Choose the G4 for maximum performance and screen real estate; select the B3 for genuine OLED quality without premium pricing.
