实测数据
Performance
Gaming is where this TV absolutely sings. A 120Hz panel with full HDMI 2.1 support, G-Sync, and FreeSync puts it in the 99th percentile of our database, and that 0.1ms response time feels instantaneous. The display itself is stunning, ranking in the 97th percentile, with those inky blacks OLED is famous for. But the picture quality score sits at a mediocre 36th percentile, dragged down by peak brightness that just can't compete with high-end QLEDs. The built-in 2.0 channel audio is a weak spot too, landing in the 46th percentile, so you'll definitely want a soundbar. The Alpha 8 processor does a solid job upscaling, but the smart TV experience is just average, a 67th percentile finish for webOS.

vs Competition
Stacked against the Sony BRAVIA XR A95L, the B5 gives up a lot in picture processing and brightness, but it's a much better pure gaming monitor. The Samsung QN900F is an 8K brightness monster that will crush the B5 in a bright living room, but it can't touch the LG's perfect black levels for movie watching. If you're on a tighter budget, the TCL QM7K and Hisense U7 are mini-LED alternatives that get significantly brighter for less money, though you'll lose the viewing angles and absolute contrast of OLED. The B5 carves out a niche as the big-screen OLED for dark-room enthusiasts who prioritize gaming.

价格
Value & Pricing
Pricing on this set is all over the map, with a wild spread from $2,700 to over $71,000 depending on the vendor. At the low end, you're getting a massive 83-inch OLED for a price that undercuts a lot of the competition, which is a serious value proposition. But if you're looking at the higher end of that range, you're stepping into territory where a brighter, more feature-rich OLED like LG's own C4 or a Sony A95L makes a lot more sense. Shop carefully and the B5 can be a steal.

Overview
LG's B5 is their entry-level OLED for 2025, and the 83-inch version is a statement piece. You get that perfect OLED contrast, over 8 million self-lit pixels, and the updated Alpha 8 Gen2 processor handling the heavy lifting. It's built for movie nights and gaming marathons in a light-controlled room, not for fighting a wall of windows at noon.
Common Questions
Q: Does this TV need an internet connection if I only use an Apple TV?
Nope, the TV itself can stay offline. Just plug your Apple TV into an HDMI port and make sure the Apple TV has its own internet connection, and you're all set.
Q: Is the LG B5 bright enough for a room with lots of windows?
Honestly, no. The B5's peak brightness is its main weakness, and it will look washed out in a bright room. You'd be much happier with a brighter QLED or a higher-tier OLED like the LG C4.
Who Should Skip This
Skip the B5 if this is going in your main, sun-drenched living room. The low peak brightness will drive you crazy during daytime viewing. You should also look elsewhere if you want a premium smart TV experience or booming built-in audio without a soundbar, as both are just average here.
Verdict
The LG B5 is a purpose-built machine. It's for the person with a dedicated media room or basement who wants the biggest possible OLED canvas for movies and games without paying for flagship processing they might not need. If that's you, and you find it at a price near the low end of its range, it's a fantastic buy.
