The LG B4 OLED 55 and the LG G5 OLED represent two distinct tiers within LG’s 2025 OLED lineup, each targeting different priorities in picture performance and overall value. Public reviews and manufacturer specifications show the B4 delivering strong contrast, accurate color, and reliable motion handling at a more accessible $1,099.99 price point, while the G5 commands $2,499.99 with a larger 65-inch panel, brighter peak output, and a more rigid, gallery-style mounting system that reduces visible hardware. Brightness measurements, input lag figures, and build details drawn from aggregated expert tests highlight the G5’s edge in premium construction. And screen size, yet many observers note the B4 remains competitive for typical living-room viewing distances. The short version: choose the B4 if budget. And 55-inch fit are primary concerns, or step up to the G5 when the larger panel and refined chassis justify the added cost.

Verdict: The B4 wins on price ($1,099.99 vs $2,499.99) while the G5 wins on size (65 in vs 55 in) and premium build.

Winner: LG G5 OLED

LG B4 OLED 55: 7.2/10

LG G5 OLED: 8.4/10
