There was a time when my living room felt incomplete, lacking that central hub for entertainment that truly brought movies, shows, and games to life. The picture quality on my old TV was simply inadequate, with murky blacks and washed-out colors that pulled me right out of the immersive experience. This problem desperately needed a solution; otherwise, every evening would continue to be a compromise, with visual details lost and the full impact of cinematic content severely diminished. I wished I had known about the LG 77-Inch Class OLED B4 Series Smart TV 4K Processor Flat Screen with Magic Remote AI-Powered with Alexa Built-in (OLED77B4PUA, 2024) back then, as it would have significantly elevated my home viewing and gaming.

Navigating the Television Landscape: Pre-Purchase Considerations
When embarking on the quest for a new television, one is often driven by the desire to overcome common shortcomings of older sets, such as poor contrast, sluggish performance, or limited smart features. A new TV, especially one in the premium category, promises to resolve these issues, delivering crisp visuals, vibrant colors, and seamless access to a world of digital content. The ideal customer for an advanced television like an OLED would be someone who values absolute picture fidelity, particularly deep blacks and vibrant colors, and prioritizes a responsive, future-proof display for both cinematic experiences and high-performance gaming. They appreciate cutting-edge technology and are willing to invest in a premium viewing experience.
Conversely, this specific product category might not be ideal for someone on a very tight budget, or those who simply need a basic display for casual viewing without a strong emphasis on picture perfection or advanced gaming features. For such individuals, a more affordable LED or QLED television might suffice, as they offer good picture quality at a lower price point, albeit without the infinite contrast of OLED. Before making any purchase, a discerning buyer should consider several factors: screen size relative to viewing distance, the primary use (movies, sports, gaming), resolution (4K is standard, 8K is emerging), refresh rate for smooth motion, smart TV platform and app availability, sound quality (and if a soundbar is needed), connectivity options (especially HDMI 2.1 ports for next-gen consoles), and the overall design aesthetic to complement their living space.

Unveiling the Star: A Close Look at the LG OLED B4 Series
The LG 77-Inch Class OLED B4 Series Smart TV stands as a testament to LG’s continued innovation in the display market. It’s LG’s 2024 “entry-level” OLED offering, promising an exceptional 4K viewing experience with self-lit pixels that deliver unparalleled blacks and vibrant colors. Upon purchase, you receive the impressive 77-inch flat-screen TV itself, the intuitive Magic Remote MR24 (complete with AA batteries), a power cable, and essential guides to get you started. While often positioned as the more accessible sibling to LG’s C-series OLEDs (like the C4), the B4 series still packs a significant punch, offering many of the premium features that define LG’s OLED line, often at a more attractive price point. Compared to previous iterations like the B8, the B4 boasts significant advancements in brightness and processing power, making it a truly modern display.
This particular OLED B4 TV is ideally suited for home theater enthusiasts who crave cinematic immersion, as well as serious gamers demanding ultra-low input lag and high refresh rates. It’s for those who appreciate seeing every detail, from the darkest shadows to the brightest highlights, without compromise. However, it might not be the best choice for those whose primary viewing involves static content for extremely long durations, although burn-in concerns have significantly diminished with newer OLED generations.
Here’s a quick look at the pros and cons:
Pros:
* Stunning Picture Quality: Self-lit OLED pixels deliver infinite contrast, true blacks, and 100% Color Volume and Fidelity.
* Exceptional Gaming Performance: Features a 144Hz refresh rate, 0.1ms response time, NVIDIA G-Sync, AMD FreeSync Premium, and VRR support across all four HDMI 2.1 inputs.
* Advanced AI Processor: The α8 AI Processor 4K optimizes picture and sound automatically.
* Intuitive Smart TV Experience: webOS 24 with a vast array of streaming apps and 300+ free LG Channels, plus a versatile Magic Remote.
* Cinematic Audio and Visuals: Supports Dolby Vision, Filmmaker Mode, and Dolby Atmos for an immersive experience.
Cons:
* Processor Speed (Relative): While powerful, the α8 AI Processor is slightly less robust than the α9 found in higher-tier LG OLEDs (like the C4), leading to marginally slower app loading or menu navigation.
* Remote Design Changes: The Magic Remote no longer stands upright and lacks dedicated play/pause buttons, which can be a minor inconvenience for some users.
* HDMI Port Placement: Two of the four HDMI ports are located on the back rather than all on the side, which can make cable management challenging for wall-mounted setups.
* Sound Quality (Out-of-the-box): While improved with AI Sound Pro, some users might still find the built-in speakers average compared to dedicated sound systems, necessitating a soundbar for true audiophiles.
Deep Dive into Performance: Features and Their Advantages
Self-Lit Pixels: The OLED Difference
The core of the LG OLED B4 Series Smart TV lies in its self-lit pixel technology. Unlike traditional LED TVs that rely on a backlight, each of the B4’s over 8 million pixels generates its own light. This means individual pixels can turn completely off, resulting in true, inky blacks with no light bleed or “blooming” around bright objects. The benefit is immediately apparent: scenes with high contrast, like stars in a night sky or explosions against a dark backdrop, are rendered with breathtaking clarity and depth. Colors pop with incredible accuracy and vibrancy, boasting 100% Color Volume and Fidelity, meaning colors remain consistent and rich even at varying brightness levels. This creates an unbelievably immersive and realistic picture that truly pulls you into the content.
α8 AI Processor 4K: The Brains Behind the Beauty
At the heart of the LG B4 is the α8 AI Processor 4K. This intelligent chip is constantly working behind the scenes to optimize your viewing experience. With AI Picture Pro, it automatically identifies the type of content you’re watching—be it a movie, sports, or a video game—and fine-tunes the picture settings in real-time for the best possible visual fidelity. This means less fiddling with settings and more time enjoying perfectly optimized content. The processor also enables features like Multi View, allowing you to split your screen into two distinct views, which is fantastic for multitasking, like watching a sports game while keeping an eye on a social media feed or a game guide. While it’s slightly less powerful than the α9 processor found in LG’s C-series OLEDs, its performance is still exceptional, delivering crisp, clear images with impressive upscaling of lower-resolution content to 4K. The difference in daily use is often imperceptible to the average viewer, with only the most demanding power users noticing a marginal delay in app loading times compared to the C4.
Dolby Vision, Filmmaker Mode & Dolby Atmos: Cinematic Immersion
The LG 77-Inch OLED B4 truly brings the magic of the cinema into your home. It comes loaded with Dolby Vision, a premium HDR format that optimizes color, contrast, and brightness scene by scene, ensuring that every detail, from the brightest highlights to the deepest shadows, is displayed with stunning accuracy. Coupled with Dolby Atmos, which creates multi-dimensional sound that flows all around you, the experience is incredibly immersive. You don’t just watch the action; you feel like you’re in the center of it. Additionally, the inclusion of FILMMAKER MODE allows you to see films exactly as the director intended, preserving original aspect ratios, colors, and frame rates. This suite of technologies transforms casual viewing into a truly cinematic event, elevating everything from blockbuster movies to nature documentaries.
webOS 24 & LG Channels: Seamless Smart Experience
LG’s webOS smart TV platform has long been praised for its intuitive interface, and webOS 24 on the LG 77-Inch Class OLED B4 Series continues this tradition. It’s incredibly user-friendly, making it easier than ever to browse all your favorite streaming apps like Netflix, Disney+, Prime Video, and Apple TV. The layout is smart and easy to customize, allowing quick access to your most-used services. Furthermore, LG Channels provides access to over 300 free channels covering sports, fitness, cooking, and more, offering a vast array of content without extra subscriptions. The integrated web browser is also robust, capable of blocking many native ads, which is a surprisingly useful feature. The operating system is snappy and responsive, making navigation a breeze, though as noted, some users coming from higher-tier processors might notice a fractional difference in speed.
Gaming Prowess: A Gamer’s Dream
For gamers, the LG B4 OLED TV is nothing short of exceptional. It’s packed with features designed to give you a competitive edge and an incredibly smooth experience. The native 120Hz refresh rate, which can go up to 144Hz for Variable Refresh Rate (VRR) content, ensures fluid motion without tearing or stuttering. Coupled with an astonishing 0.1ms response time, input lag is ridiculously low, making every command instantly register on screen. All LG OLED TVs, including the B4, support NVIDIA G-Sync, AMD FreeSync Premium, and VRR, further enhancing gaming quality by synchronizing the TV’s refresh rate with the console or PC’s frame rate. With four HDMI 2.1 inputs, you can connect all your next-gen consoles and gaming PCs, enjoying 4K at 120Hz (or 144Hz with VRR). The LG Game Dashboard and Game Optimizer put all your gaming controls and settings at your fingertips, allowing for quick adjustments mid-game. However, one minor frustration some users noted is the placement of two of the four HDMI ports on the back of the TV, which can be awkward for wall-mounted setups where side-facing ports are much more accessible. This is a design choice that could be improved for better user convenience.
Magic Remote and AI-Powered Voice Control
The included Magic Remote MR24 is another standout feature, enhancing the overall user experience. Its unique point-and-click functionality acts like a mouse, making navigation through menus and typing much faster than traditional directional buttons. While some users might not always prefer the pointer, it can be easily deactivated if not desired. The voice activation feature is excellent, allowing you to search for content not just across the entire TV’s ecosystem but also within specific apps, which is a significant time-saver. The remote feels good in hand with a satisfying weight. One common point of feedback, however, is that LG removed the dedicated play and pause buttons, requiring users to rely on the central scroll wheel for these functions. Additionally, unlike older Magic Remote versions, the MR24 doesn’t stand upright, which some users found less convenient for tabletop placement. Despite these minor design shifts, the remote remains a highly functional and intuitive control device.
webOS Re:New Program: Future-Proofing Your Investment
A significant advantage for longevity and value is LG’s webOS Re:New Program. This program guarantees new software updates and feature refreshes for five years. This commitment from LG means that your B4 series TV will continue to evolve and receive performance improvements and new functionalities long after your purchase. In a world where technology rapidly advances, having a TV that continues to get smarter and more capable over time is a tremendous benefit, ensuring your investment remains relevant and optimal for years to come. This commitment to continuous improvement stands out compared to other brands that may cease software updates much sooner, ensuring that the apps continue to run smoothly and features remain current.
Voices from the Living Room: What Users Are Saying
Having scoured the internet, it’s clear that real users are overwhelmingly positive about the LG 77-Inch Class OLED B4 Series Smart TV. Many first-time OLED owners express absolute shock at the picture quality, noting the profound difference in blacks and overall clarity compared to their previous non-OLED 4K sets. The deep, inky blacks and vibrant colors are frequently highlighted as transformative. Several users were particularly impressed by the AI sound feature, stating it delivers surprisingly rich and room-filling audio, often negating the immediate need for an external soundbar. The Magic Remote, despite minor design changes like the absence of dedicated play/pause buttons, receives praise for its intuitive pointer and voice search capabilities. Gamers consistently laud the incredibly low input lag and high refresh rates, declaring it perfect for their needs. While some mention the slight processor difference from higher models, or the inconvenient placement of some HDMI ports for wall mounting, the consensus is that the B4 offers phenomenal value and an unparalleled viewing experience for what’s considered an “entry-level” OLED. Many shared sentiments about being completely spoiled by the OLED picture and never wanting to return to conventional LED displays.
