LG B3 Series 77-Inch Class OLED Smart TV OLED77B3PUA, 2023 Review: My Long-Term Experience with AI-Powered 4K and Alexa

Stepping into the world of truly immersive home entertainment can be a game-changer, and for me, the nagging issue of a lackluster viewing experience had become unbearable. My old television simply couldn’t deliver the crisp visuals and vibrant colors that modern content demanded, making movie nights and gaming sessions feel less than spectacular. If only I had known about the LG B3 Series 77-Inch Class OLED Smart TV OLED77B3PUA, 2023 sooner; it would have drastically improved my quest for cinematic excellence and prevented countless moments of visual disappointment that ultimately diminished my enjoyment. The problem needed solving because a truly engaging display is fundamental to enjoying today’s high-definition media, and without it, one misses out on the full artistic intent of creators, transforming potential spectacle into mere background noise.

When embarking on the journey to purchase a new smart TV, one is often driven by the desire to elevate their home entertainment. Whether it’s to experience movies with cinematic fidelity, dive into games with unparalleled responsiveness, or simply enjoy everyday broadcasts with superior clarity, a good TV solves the problem of visual compromise. The ideal customer for an advanced smart TV, particularly one with OLED technology, is someone who values picture quality above all else – a cinephile, a dedicated gamer, or simply someone who appreciates vivid colors, true blacks, and wide viewing angles. They are often willing to invest more for this premium experience. On the other hand, if you’re primarily watching standard definition content, have a very bright room with uncontrollable ambient light, or are on a very strict budget, an OLED might be overkill. In such cases, a high-quality QLED or LED TV might offer better value or brightness for your specific environment. Before making your purchase, consider screen size relative to your viewing distance, the display technology (OLED, QLED, LED) and its pros/cons, refresh rate for smooth motion, smart TV platform features, connectivity options (especially HDMI 2.1 for gaming), audio capabilities, and crucially, your budget. Thinking about how and where you’ll use the TV will help you pinpoint the perfect fit.

Presenting the product

The LG B3 Series 77-Inch Class OLED Smart TV OLED77B3PUA, 2023 is LG’s entry-level 77-inch OLED offering for 2023, promising an unparalleled viewing experience with perfect blacks and infinite contrast, typically only found in premium displays. It arrives with a Magic Remote (complete with AA batteries), a power cable, and a quick start guide, ensuring you have everything needed for initial setup. While LG’s C3 and G3 series are considered the market leaders in their respective segments for brighter panels and advanced processors, the B3 stands out by bringing the core OLED benefits at a more accessible price point, often seen as a significant upgrade from its predecessor, the B2, especially in processing power. This specific product is ideal for those who prioritize stunning picture quality for movies, streaming, and gaming without breaking the bank on the absolute flagship models. It’s less suited for individuals who need the brightest possible TV for a sun-drenched living room or those who are extremely budget-conscious and for whom any OLED is too expensive.

Pros:
* Perfect Blacks & Infinite Contrast: Self-lit pixels deliver unparalleled contrast and true black levels.
* Stunning 4K OLED Picture: Vibrant colors, incredible depth, and sharp 4K resolution.
* Excellent for Gaming: Native 120Hz refresh rate, 0.1ms response time, G-Sync, FreeSync Premium, VRR, and four HDMI 2.1 ports.
* Powerful AI Processing: α7 AI Processor Gen6 enhances picture and sound quality automatically.
* Intuitive Smart Platform: webOS 23 with Quick Cards and Magic Remote for easy navigation.

Cons:
* Lower Peak Brightness: Not as bright as the higher-tier C3 or G3 LG OLED models, which might impact HDR in very bright rooms.
* Heavy and Awkward for Setup: Its thin panel and large size make it challenging to unbox and mount with fewer than two or even three people.
* Initial Pixel Refresh Needed: Some users reported faint lines requiring a pixel refresh cycle (which is normal operation but unexpected initially).
* Magic Remote Pointer Cannot Be Disabled: A minor inconvenience for some users who prefer not to use the on-screen pointer.

Features & Benefits

SELF-LIT OLED 4K Display

The core of the LG OLED77B3PUA‘s visual prowess lies in its self-lit OLED 4K display. Unlike traditional LED TVs that rely on a backlight, each of the LG OLED’s over 8.3 million pixels can turn on and off individually. This fundamental difference is what enables “perfect black,” meaning when a pixel is off, it emits absolutely no light. The benefit of this is immediately apparent: scenes with deep shadows or starry nights are rendered with astonishing realism, as there’s no light bleed to muddy the dark areas. This level of precise light control also leads to “infinite contrast,” where the brightest whites can sit directly next to the deepest blacks without any haloing or blooming. For the viewer, this means an incredibly immersive picture, bursting with vibrant colors and rich detail that truly pops off the screen. Whether you’re watching a visually stunning nature documentary, a suspenseful film noir, or a vibrant animated movie, the dynamic range is simply breathtaking. Furthermore, the native 120Hz refresh rate ensures that fast-moving action, be it in sports or high-octane gaming, is displayed with exceptional smoothness and clarity, minimizing motion blur and providing a truly lifelike experience. This makes the B3 an outstanding choice for viewers who demand the highest fidelity in their visual entertainment, offering a clarity and depth that simply cannot be matched by conventional display technologies.

a7 AI Processor Gen6

At the heart of the LG B3 Series OLED TV‘s intelligence is the α7 AI Processor Gen6. This powerful chip is the brain behind the TV’s optimized performance, using artificial intelligence to constantly analyze and enhance both picture and sound quality in real-time. What this means for the user is an effortlessly superior viewing experience. The AI Picture Pro feature intelligently detects the type of content you’re watching – whether it’s a fast-paced sports match, a dialogue-heavy drama, or a vibrant animated film – and then applies optimal settings to improve resolution, color, and contrast. AI Upscaling takes lower-resolution content and intelligently scales it up to near-4K quality, ensuring that even your older DVDs or standard cable broadcasts look remarkably clear and detailed on the large 77-inch screen. Beyond visuals, the processor also enhances audio through AI Sound Pro, which can virtualize surround sound, making dialogue clearer and sound effects more impactful, pulling you deeper into the action. This sophisticated processing eliminates the need for manual adjustments, as the TV intelligently adapts to deliver the best possible picture and sound, taking the guesswork out of optimizing your entertainment and allowing you to simply sit back and enjoy a truly immersive experience from the moment you turn it on.

webOS 23 & LG Channels

The smart capabilities of the LG B3 are powered by webOS 23, the latest iteration of LG’s renowned smart TV platform. This intuitive operating system is designed for effortless navigation and quick access to your favorite content. The user interface is clean and highly customizable, allowing you to group your most-used apps into “Quick Cards” for instant access. This significantly reduces the time spent searching and increases the time spent streaming your preferred shows, movies, and sports. Coupled with the innovative Magic Remote, which offers a point-and-click interface much like a mouse, navigating through menus and selecting content becomes incredibly fluid and enjoyable. No more endlessly pressing directional buttons; simply point, click, and you’re there. Beyond the major streaming services like Netflix, Disney+, Prime Video, and Hulu, the LG B3 also offers LG Channels, providing instant access to over 300 free channels, ranging from news and sports to entertainment and fitness, directly integrated into the TV’s interface. This expansive selection of content, combined with the seamless user experience, ensures that you’ll always find something to watch, catering to a wide variety of interests and making your TV the central hub of your home entertainment. The integration of Alexa Built-in also means hands-free control for many functions, adding another layer of convenience.

DOLBY VISION + HOME THEATER

For those who crave a true cinematic experience at home, the LG B3 Series 77-Inch Class OLED Smart TV delivers with its comprehensive home theater support. Every LG OLED comes loaded with Dolby Vision, a premium HDR (High Dynamic Range) format that goes beyond standard HDR10 to provide extraordinary color, contrast, and brightness, scene by scene. This dynamic metadata ensures that content is displayed exactly as the creators intended, with finer detail in both the brightest highlights and the darkest shadows. The result is a picture that boasts incredible depth and realism, making every frame feel more alive. Complementing the stunning visuals is Dolby Atmos audio, which provides multi-dimensional, wrap-around sound. While the B3’s internal speakers provide a solid foundation, pairing it with a compatible sound system allows you to experience soundscapes that envelop you, with audio cues coming from all directions, truly placing you in the center of the action. Furthermore, LG’s FILMMAKER MODE is a thoughtful inclusion for movie enthusiasts. This picture mode disables motion smoothing and other post-processing effects, preserving the original aspect ratios, colors, and frame rates of films. It’s designed to ensure you see movies precisely as the director intended, providing an authentic, unadulterated cinematic experience right from the comfort of your couch.

ULTIMATE GAMEPLAY

The LG B3 is not just a TV for movie buffs; it’s a serious contender for gamers, packed with features designed to give you the competitive edge. One of the most critical aspects for gaming is response time, and the B3 boasts an incredibly fast 0.1ms response time, virtually eliminating ghosting and motion blur. This, combined with the native 120Hz refresh rate, ensures crisp, smooth imagery, even in the most frantic gaming sequences. Input lag is also kept to a minimum, meaning your controller inputs translate almost instantaneously on screen, which is crucial for competitive gaming. What truly sets LG OLEDs apart for gaming is their support for advanced technologies: NVIDIA G-Sync, AMD FreeSync Premium, and Variable Refresh Rate (VRR). These technologies synchronize the TV’s refresh rate with your console or PC’s frame rate, preventing screen tearing and stuttering for an incredibly fluid and tear-free gaming experience. The presence of four HDMI 2.1 inputs is another huge advantage, allowing you to connect multiple next-gen consoles (like PS5 and Xbox Series X) and a gaming PC simultaneously, all while benefiting from the full bandwidth needed for 4K at 120Hz, VRR, and ALLM (Auto Low Latency Mode). Whether you prefer console gaming or delving into cloud gaming services, the LG Game Dashboard and Game Optimizer put all the essential gaming settings – from picture modes tailored for specific genres to VRR status and input lag measurements – right at your fingertips, offering unprecedented control and customization. This makes the B3 an exceptional display for any serious gamer looking for an immersive and responsive experience.

Social Proof

After scouring numerous online forums and customer reviews, it’s clear that owners of the LG B3 Series OLED TV are largely thrilled with their purchase. Many rave about the spectacular picture quality, noting the stunning clarity and vibrant colors that truly make content pop, especially when viewing from various angles. Users frequently highlight the incredible sound, attributing it to the AI Sound technology. While some found the TV’s thinness and considerable weight made initial setup a two- or even three-person job, and a few mentioned needing to run the pixel refresh cycle early on to clear faint lines, these were generally seen as minor hurdles. The consensus points to immense satisfaction with the value, especially for an OLED of this size, with many calling it the best TV they’ve ever owned.

Conclusion

The pursuit of an exceptional home entertainment experience often hits a wall with subpar displays that fail to capture the full beauty of modern media. Without a TV capable of true blacks, vibrant colors, and smooth motion, you’re constantly fighting visual limitations, leading to a less engaging and ultimately frustrating viewing experience. The LG B3 Series 77-Inch Class OLED Smart TV OLED77B3PUA, 2023 stands out as a superb solution to this problem. Its self-lit OLED pixels provide unparalleled contrast and color accuracy, the α7 AI Processor Gen6 intelligently optimizes every frame, and its robust gaming features ensure an incredibly responsive and fluid experience. For anyone seeking to transform their living room into a true cinematic and gaming hub without venturing into premium pricing, the LG B3 is an outstanding choice.
