LG G4 77" vs Vizio P-Series Quantum 65"
The Verdict
LG's 77-inch G4 OLED dominates with superior picture quality, delivering 2100 nits peak brightness, perfect blacks via OLED technology, and LG's advanced α11 AI upscaling processor. Gaming performance excels with 1ms input lag versus Vizio's 8ms, paired with comprehensive VRR/ALLM support. Audio capabilities far exceed the competition at 4.2ch/60W with Dolby Atmos versus Vizio's basic 2.0ch/20W setup. However, Vizio's 65-inch P-Series offers exceptional value at $999,quantum dot technology delivers strong color vibrancy and adequate 1200-nit brightness for most viewing conditions. Full-array local dimming provides decent contrast control. Both support 120Hz and Wi-Fi 6, though LG's webOS 24 with ThinQ AI outperforms Vizio's SmartCast platform. Size matters here: LG's 77 inches versus 65 inches justifies much of the premium for home theater enthusiasts. Vizio suits budget-conscious buyers seeking solid 4K performance without OLED's premium pricing. For picture quality and gaming, LG G4 wins decisively; for value-conscious shoppers, Vizio delivers impressive specifications at half the price.
