The LG B4 OLED 55 and the LG G5 OLED 83 inch TV represent two distinct tiers within LG’s 2025 OLED lineup, differing in size, panel technology, refresh rate capability, and overall performance expectations. Public reviews and manufacturer specifications show the LG B4 OLED 55 relying on a standard WOLED panel with 120 Hz native refresh. And solid brightness for its class, while the LG G5 OLED 83 inch TV uses the brighter OLED EVO panel, supports 165 Hz with variable refresh rate. And scales its processing and heat management to the much larger chassis. Contrast, color accuracy, and motion handling remain excellent on both sets, yet the G5’s larger surface area. And higher peak luminance deliver a visibly more immersive picture in brighter rooms or at greater viewing distances. The short version: choose the LG G5 OLED 83 inch TV only if the space and $5,299.99 budget align with its technical advantages; otherwise the LG B4 OLED 55 remains the rational pick for most buyers.

Verdict: Pick LG G5 OLED 83" TV if you have the space for an 83-inch screen and the budget for the $5,299.99 price tag to get the OLED EVO panel and 165Hz VRR. The G5 is the superior piece of technology, but the B4 is the rational choice for most room sizes and budgets.

LG B4 OLED 55 lists at $29.94 while LG G5 OLED 83" TV lists at $4,738.1 — LG B4 OLED 55 undercuts LG G5 OLED 83" TV by $4,708.16 (15725%).
