The LG B4 OLED 55 and the Sony A80K 55 are both 55-inch OLED televisions that rely on self-emissive pixels for deep blacks. And accurate color reproduction, yet they diverge in processing priorities and feature sets according to aggregated reviewer measurements and manufacturer specifications. Public data shows the LG B4 OLED 55 ships with confirmed 120 Hz panel support, four HDMI 2.1 ports, and variable refresh rate compatibility that reviewers consistently cite for console and PC gaming, while its α7 processor emphasizes motion handling and upscaling. The Sony A80K 55, built around the Cognitive Processor XR, receives praise in early coverage for natural color gradation. And sound-from-screen acoustic design, though official 120 Hz confirmation and peak brightness figures remain unpublished at the time of most comparisons. Differences in smart platform — webOS versus Google TV, also shape daily navigation and app ecosystems as noted across retail and editorial sources. The short version: choose the LG B4 OLED 55 if 120 Hz gaming performance at the current $1,099.99 price is the priority, or the Sony A80K 55 if brand familiarity and pending specification details matter more.

Verdict: Pick LG B4 OLED 55 if you need confirmed 120Hz gaming performance and know the price ($1,099.99). Pick Sony A80K 55 if you prefer Sony’s brand and can wait for official specs. Neither publishes peak brightness yet.

LG B4 OLED 55 lists at $29.94 while Sony A80K 55 lists at $39.99 — LG B4 OLED 55 undercuts Sony A80K 55 by $10.05 (34%).

Winner: LG B4 OLED 55
