Performance
The picture is the star here. Over 8.3 million self-lit pixels mean contrast is effectively infinite, and the B5's brightness is a genuine step up from older OLEDs. The Alpha 8 Gen 2 processor handles upscaling like a champ, so even cable TV and old YouTube clips look respectable. Motion handling is smooth, which matters if you watch sports or play fast games. Gaming gets 120Hz, G-SYNC, FreeSync, and HDMI 2.1 across all four ports, so no dongle roulette. The built-in 2.0 channel audio is fine for casual viewing, but it's not going to rattle your walls. Plan on a soundbar if you want the full experience.

vs Competition
The Sony BRAVIA XR XR77A95L is the natural rival, and it trades blows on picture processing but typically costs more. Samsung's Neo QLED QN75QN990FFXZA gets brighter in a bright room, but it can't match OLED's per-pixel contrast. The TCL QM7K and Hisense U8 are the value plays, offering big screens for less cash, but they're LED panels with blooming and off-angle compromises. If you want the OLED look without the Sony tax, the B5 is the sweet spot.

Value & Pricing
Pricing is all over the map right now. We're seeing USD 1,085 to USD 3,000 across seven US listings, which is a wild spread. If you can snag one near the low end, this is an absolute steal for a 77-inch OLED. At the high end, you're paying early-adopter tax on a 2025 model. Best Buy has open-box options that could land you in the sweet spot. Shop around before you commit.

Overview
The LG B5 is the OLED that makes you wonder why you waited so long. It's a 77-inch slab of self-lit pixels that nails the fundamentals: perfect blacks, punchy color, and motion so smooth it almost feels unfair. The Alpha 8 AI Processor Gen 2 does the heavy lifting behind the scenes, upscaling whatever junk you throw at it into something watchable.
This is the 2025 model, and LG clearly spent the year polishing rather than reinventing. You get Dolby Vision, a 120Hz panel, G-SYNC and FreeSync support, and webOS with a promise of five years of updates. It's not the cheapest 77-inch TV out there, but owners are basically glowing about it, and our sentiment data backs that up.
Common Questions
Q: Does this TV support 4K at 120Hz for gaming?
Yes, all four HDMI ports are HDMI 2.1 and support 4K at 120Hz, plus G-SYNC and FreeSync for tear-free gaming.
Q: Is the built-in audio good enough, or do I need a soundbar?
The 2.0 channel speakers with Dolby Atmos are fine for casual viewing, but a soundbar is recommended for movies and gaming.
Q: How does the B5 compare to the more expensive LG G series?
The B5 uses the Alpha 8 Gen 2 processor rather than the higher-end Alpha 11, so it's slightly less powerful for upscaling, but it still delivers excellent picture quality for most people.
Who Should Skip This
Skip this if you're putting it in a bright, sun-drenched room. OLEDs have come a long way, but a QLED like the Samsung QN75QN990FFXZA will fight glare better. Also skip it if you're on a strict budget, the TCL QM7K or Hisense U8 will get you a big screen for less, just without the OLED magic.
Verdict
Buy this if you want a big, beautiful OLED that handles movies, sports, and gaming without breaking a sweat. It's especially good for dark-room viewing, where those perfect blacks do their best work. The AI upscaling is a real bonus if you watch a lot of non-4K content. Pair it with a soundbar and you've got a setup that'll keep you happy for years.
