LG OLED - B5 series 48" Class B5 Series 2025 Review

The LG B5 OLED delivers 93rd percentile gaming and audio performance for just $650. You get four HDMI 2.1 ports, 120Hz, and perfect OLED blacks. The catch? Its picture quality sits at the 47th percentile, so it's not the brightest star in the TV sky, but it's a stellar value for the right setup.

The LG B5 is a 48-inch OLED that punches way above its price tag in a few key areas. It lands in the 93rd percentile for gaming performance and audio, and its connectivity is in the 96th percentile. That means you're getting a TV that's built for modern consoles and sound systems without any compromises. For $650, that's a lot of TV. But it's not perfect across the board. Its picture quality percentile is a more modest 47th, which tells us it's good, but not the absolute best in its class. Think of it as the enthusiast's entry point into OLED.

Let's talk about where this thing shines. Gaming performance is its superpower, sitting in the 93rd percentile. That 120Hz panel with FreeSync and G-Sync compatibility means buttery smooth gameplay with no tearing. The Alpha 8 AI Processor Gen2 kicks in to optimize the picture on the fly, which is a nice touch. Audio is another high point, also in the 93rd percentile, thanks to Dolby Atmos support. It sounds way better than most built-in TV speakers. The four HDMI 2.1 ports put its connectivity in the 96th percentile, so hooking up a PS5, Xbox, soundbar, and a spare port is no problem. The trade-off? While OLED inherently delivers perfect blacks, its overall picture quality score is only at the 47th percentile. That means other TVs, even some non-OLEDs, might offer more pop or brightness in a bright room.

At $650, the value proposition is pretty clear. You're getting near-top-tier gaming features, excellent connectivity, and great audio in an OLED package. That's a combo you usually have to pay a lot more for. Compared to its bigger, more expensive siblings like the LG C5, you're giving up some peak brightness and maybe a few processor tricks, but you're saving a significant chunk of change. For the price, it's one of the most compelling ways to get into the OLED world.

Stacked against the competition, the B5 carves out a niche. The LG C5 evo will have better picture quality and brightness, but costs more. The Samsung S85D OLED is a direct competitor, often trading blows on price and performance; the B5 might have a slight edge in smart features with webOS. Against mini-LED TVs like the Hisense U6 or TCL QM8, you lose sheer brightness and size-for-dollar, but you gain the perfect blacks and pixel-level control that only OLED can offer. For a dedicated gaming setup or a media room where lights are controlled, the B5's strengths outweigh its weaknesses.

If your main living room is flooded with sunlight, you might want to think twice. The B5's picture quality percentile of 47th means it can't compete with the peak brightness of high-end mini-LED TVs. Also, if you're looking for a massive 75-inch-plus centerpiece for movie nights, the 48-inch screen size simply isn't the right fit. This TV is built for more intimate, controlled environments.

If you're a gamer or a movie watcher who values perfect blacks and responsive performance over sheer, blinding brightness, this TV is a fantastic buy. The data shows it excels exactly where it needs to for those use cases. Its weaknesses in overall picture quality percentile (47th) are real, but they're the trade-off for getting OLED tech at this price. We'd recommend it in a heartbeat for a bedroom, office, or secondary living space where its 48-inch size and gaming chops make perfect sense.
