The 30-Second Version

The LG B5 65" OLED delivers stunning contrast and perfect blacks for movies, paired with elite 120Hz gaming features like G-Sync and FreeSync. It's a 99th percentile gaming TV that also scores in the 98th percentile for overall display quality. At around $1,200, it brings premium OLED tech down to a very competitive price point. If you want a cinematic, responsive all-rounder for a dimmer room, this is one of the best values in TVs right now.

Overview

If you're looking for a TV that makes you feel like you've snuck into the back row of a movie theater, the LG B5 65" OLED is a serious contender. It's LG's play to bring that legendary OLED contrast—where blacks are truly black, not just dark gray—to a more accessible price point. It's packing over 8.3 million self-lit pixels and LG's second-generation Alpha 8 AI processor, which means it's smart enough to tweak the picture and sound on the fly.

This TV is built for people who care about picture quality but also want a living room that doesn't feel like a dedicated home theater. It's for the movie buff who also logs serious hours on a PlayStation 5 or Xbox Series X. The gaming features are a huge part of the story here, with a 120Hz refresh rate and support for both NVIDIA G-Sync and AMD FreeSync, which is basically a cheat code for smooth, tear-free gameplay.

What makes it interesting is the balance. It's not LG's absolute top-tier model, but it takes the core OLED magic—perfect blacks, infinite contrast, and wide viewing angles—and pairs it with a processor and gaming chops that punch way above its weight class. You're getting a display that scores in the 98th percentile for picture, but it's the 99th percentile gaming score that really turns heads.

Performance

Let's talk about what those percentile rankings mean in your living room. A 98th percentile display score and a 94th percentile HDR score translate to a picture that's stunningly immersive. The OLED panel delivers that 'wow' factor with deep, inky blacks that make colors pop, especially with Dolby Vision content. The Alpha 8 AI processor does a solid job upscaling lower-resolution content, so your old DVDs or standard-def streams won't look quite as rough. Our data shows it's rated 85.9/100 for movies, which feels about right—it's a fantastic film-watching experience.

The real shocker is the gaming performance. A 99th percentile score isn't a typo. The combination of a 120Hz native refresh rate, a near-instantaneous 0.1ms response time, and variable refresh rate (VRR) support from both major GPU brands makes this one of the most responsive big-screen gaming displays you can buy. It's rated 94.2/100 for gaming, which puts it in the same conversation as dedicated gaming monitors twice the price. The only slight letdown is the audio, which lands in the 80th percentile. The built-in speakers are fine for everyday TV, but for movies or gaming, you'll want a soundbar or a proper surround setup to match the visual spectacle.

Pros & Cons

Pros

  • OLED picture quality with perfect blacks and infinite contrast, scoring in the 98th percentile for display quality. 99th
  • Elite gaming performance (99th percentile) with 120Hz, VRR, and support for both G-Sync and FreeSync. 96th
  • Excellent HDR support (94th percentile) covering Dolby Vision, HDR10, and HLG for vibrant, dynamic content. 96th
  • Strong smart TV platform with webOS 25, which is intuitive and has wide app support, ranking in the 85th percentile. 95th
  • Future-proofed connectivity with 4 HDMI ports, Wi-Fi 6E, and Bluetooth 5.3, scoring 93rd percentile.

Cons

  • Built-in audio is the relative weak point at the 80th percentile; it's adequate but doesn't match the visual grandeur.
  • Picture quality score of 45th percentile suggests it may not reach the absolute peak brightness of more expensive OLEDs or high-end Mini-LEDs.
  • Not a bright room champion; OLEDs can struggle with glare in very sunny spaces compared to some LED competitors.
  • While good, the social proof score of 67th percentile indicates it's less reviewed or discussed than some flagship rivals.
  • At 65 inches and 38 pounds, it's not what you'd call portable (rated 50.5/100), but let's be real, you're not moving it often.

The Word on the Street

4.5/5 (28 reviews)
👍 Owners are consistently blown away by the picture quality, specifically calling out the inky black levels and vibrant colors, especially when watching HDR or Dolby Vision content.
👍 Gamers report an exceptionally smooth and responsive experience, with the 120Hz refresh rate and variable refresh rate support eliminating screen tearing and making fast-paced games feel incredibly fluid.
🤔 While the picture gets universal praise, several users note that the built-in speakers are merely adequate, describing them as 'okay' or 'fine,' leading many to immediately budget for a separate sound system.
👍 The webOS smart platform receives positive feedback for being intuitive and easy to navigate, with users appreciating the wide selection of streaming apps and the convenience of the Magic Remote.

Value & Pricing

Priced around $1,200, the LG B5 sits in that sweet spot where premium OLED technology starts to feel attainable. You're not paying for the absolute brightest panel or the sleekest designer stand, but you are getting the core OLED viewing experience and a gaming feature set that rivals TVs costing hundreds more. It represents a classic 'value flagship' move from LG: take last year's top-tier tech, refine the processor, and offer it at a friendlier price.

Compared to the competition, this price puts it squarely against high-end Mini-LED TVs from TCL and Hisense, which can get brighter but can't match OLED's contrast. It's also notably less expensive than LG's own higher-end OLED evo models or Sony's premium offerings, which chase that last 5% of picture refinement. For the money, you're getting an outstanding balance of movie-watching immersion and cutting-edge gaming performance.

vs Competition

The most direct competitors are other TVs in the $1,000-$1,500 range. The TCL QM8 (QD-Mini LED) and Hisense U6 Series (Mini-LED) will beat the B5 in sheer peak brightness, making them better for very bright rooms. However, they can't physically turn off individual pixels like an OLED, so their black levels and contrast can't quite match the 'pop' of the LG. For dedicated dark room viewing, the B5's OLED panel has a clear advantage.

Then there's the step-up within LG's own lineup, like the OLED evo G5 series. You'll pay more for marginally better brightness and perhaps a sleeker design, but the core gaming features and OLED goodness are largely the same. The Sony BRAVIA 5 is another interesting foil, often praised for its superior motion handling and color accuracy out of the box, but it typically commands a higher price for similar screen tech. The B5's ace in the hole is its comprehensive gaming support, which is often more complete than what you find at this price point from Sony or Samsung.

Common Questions

Q: Do I need to connect this TV to the internet to use it with an external streamer, like an Apple TV?

Nope, you can use the TV just as a dumb display if you want. The HDMI ports will work regardless of internet connectivity. Your Apple TV (or other device) will need its own internet connection to stream content, but the LG B5 itself doesn't require one for basic passthrough functionality.

Q: How does this TV handle bright rooms?

This is the classic OLED trade-off. While its perfect blacks are unbeatable in dim or dark rooms, it doesn't get as eye-searingly bright as some high-end Mini-LED TVs. In a room with direct sunlight on the screen, you might notice more glare and a less impactful HDR image compared to a brighter alternative. For controlled lighting, it's phenomenal.

Q: Is the 120Hz refresh rate only good for gaming?

Not at all. While gamers benefit the most, a 120Hz panel also makes general UI navigation in webOS feel buttery smooth. For movie content, the TV's processor uses that high refresh rate to improve motion handling, reducing the 'soap opera effect' on lower frame rate content when you use the correct settings.

Q: What's the difference between this B5 and LG's more expensive C5 or G5 OLEDs?

The main differences usually come down to peak brightness and processor refinements. The higher-end models use LG's 'OLED evo' panels and more advanced processors to achieve slightly higher brightness, which can make HDR highlights pop a bit more. The B5 offers the same core OLED contrast, gaming features, and smart platform at a more accessible price, sacrificing that last bit of peak luminance.

Who Should Skip This

Skip the LG B5 if your TV is going in a sun-drenched, bright room with no way to control the light. The OLED's strengths are muted by glare, and you'd be better served by a very bright Mini-LED TV like the TCL QM8 or Hisense U6/U7 series. Also, if you are an absolute audiophile who refuses to use external speakers, the built-in audio here is good but not great. For pure, critical movie watching in a pitch-black room where you want the absolute best motion handling and color accuracy out of the box, you might find the step up to a Sony BRAVIA OLED worth the extra investment. The B5 is an incredible all-rounder, but specialists might find better tools for their very specific jobs.

Verdict

For the movie lover and hardcore gamer who watches in a controlled lighting environment, the LG B5 is an easy recommendation. It delivers the transformative OLED picture quality that makes films feel cinematic, backed by a gaming spec sheet that leaves little on the table. If your weekend involves switching between Netflix's latest Dolby Vision show and a marathon session of a fast-paced shooter, this TV feels like it was built for you.

However, if your living room has massive, un-shaded windows creating a ton of glare, you might want to look at a high-brightness Mini-LED option like the TCL QM8. Similarly, if built-in audio is a top priority and you don't plan to add a soundbar, the B5's speakers are just okay. But for everyone else, this TV offers a stunning combination of visuals and performance that's tough to beat without spending a lot more money.
