LG B4 55" vs Sony A80L 65" (OLED)
The Verdict
Both are premium OLED TVs, but they target different priorities. LG's B4 at 55 inches and $1199 delivers exceptional value with a brighter 1100-nit panel, superior gaming performance (1ms input lag vs Sony's 8ms), and LG's acclaimed webOS 24 with multiple AI assistants. Picture quality remains stunning with Dolby Vision IQ support and the α8 Gen 7 processor handling upscaling admirably. Sony's A80L, meanwhile, justifies its $1999 price through a larger 65-inch screen, superior audio engineering via Acoustic Surface Audio+ with dual subwoofers, and refined design with minimal bezels (2.1mm). Both offer 120Hz refresh rates and VRR for gaming. If gaming performance and budget-consciousness matter most, the LG B4 excels despite its smaller footprint. For those wanting maximum screen real estate, immersive audio, and willing to pay premium pricing, Sony's A80L delivers a more complete cinematic experience. Choose LG B4 for value and competitive gaming; choose Sony A80L for premium 65-inch immersion.
