LG B4 2024 Overview

For a more intelligent way to play games or watch your favorite shows and movies, consider the LG OLED B4 55" 4K HDR Smart TV. Powered by the a8 AI Processor 4K, the quality of your content is automatically handled, as the processor auto-adjusts settings based on what you're watching. With the image fine-tuned, you can maximize the immersive realism that millions of self-lit OLED pixels offer in stunning 4K resolution.

Gamers should love the B4 too, as it offers a snappy 0.1 ms response time, 120 Hz refresh rate, and a host of technologies for high-end gameplay.

Smart TV
Powered by the a8 AI Processor 4K and webOS 24, the B4 delivers a host of smart TV functionality. Starting with streaming over your home network via Wi-Fi 5 (802.11ac) or Ethernet, choose from a long list of services, such as Netflix, Max, Disney+, YouTube, Prime Video, ESPN, Apple TV, Sling TV, and more. You can also choose 300+ free LG Channels that encompass sports, fitness, cooking, and more. Control and browse it all with the included remote, LG ThinQ remote app, or use your voice. The B4 works with Google Assistant and has Amazon Alexa built-in.
The Ultimate in Gaming
Gamers rejoice, as the B4 is an ideal platform to vanquish villains and dominate your opponents online. Equipped with NVIDIA G-Sync, AMD FreeSync Premium, ALLM, and VRR, you can achieve a silky smooth refresh rate along with a lightning fast 0.1 ms response time for accurate and responsive control. Connect one or more next-gen consoles to the four HDMI 2.1 inputs, and use LG's Game Dashboard and Game Optimizer to fine tune your experience.
Seamless Design
With an almost invisible bezel, the B4 all but disappears into your living room or home theater space, letting you watch or play without distraction. When the TV is not in use, there's no reason you have to live with a black rectangle in your space. The B4 lets you use it to display your favorite artwork and photos.

LG B4 2024 Reviews

Great product! Worths every cent!

By Nik
Rated 5 out of 5

I couldn’t be happier with this TV. The picture quality is crisp, vibrant, and incredibly clear — the kind of clarity that instantly makes you notice how much you were missing with your old screen. Blacks are deep, colors pop, and HDR content looks phenomenal. The sound is also impressive, with enough depth and balance that I haven’t felt the need for an external soundbar (though I might still get one for the full cinematic effect). This was a major upgrade from my previous TV, and the difference is night and day. The user interface is fast and intuitive, and the smart features make streaming effortless. If you're looking for a high-quality OLED experience without breaking the bank, the B4 is an excellent choice.

Fabulous Image Quality!

Arrived on schedule, easy to install, easy to start up. Works great. Instructions are a bit vague.
