LG's C4 model is discounted, but for budget-conscious buyers, we recommend this OLED TV alternative instead.
**LG B4 48-inch OLED TV Offers High-End Gaming Features at an Affordable Price**
In the ever-evolving world of technology, LG has introduced the B4 48-inch OLED TV, a top-tier gaming display that promises premium features at a budget-friendly price. Currently available for £520 on Amazon, this compact OLED TV offers exceptional gaming performance and a smart platform, making it an appealing choice for budget-conscious consumers.
### Key Features and Improvements
The B4 48-inch OLED TV delivers rich black levels, vivid colours, and excellent contrast, thanks to its OLED panel technology. The picture quality is described as "punchy" with "exceptional shadow detail" and good colour accuracy, particularly in LG's Filmmaker mode, making it suitable for movies and bright rooms. However, it has somewhat lower peak brightness (~656 nits) than higher-end LG models.
Equipped with four HDMI 2.1 ports, the B4 supports 4K resolution at 120Hz, catering to the demands of modern gaming. It also supports Variable Refresh Rate (VRR), including AMD FreeSync Premium and Nvidia G-Sync, reducing screen tearing and stutter. The TV features Auto Low Latency Mode (ALLM) and Dolby Vision Gaming, enhancing responsiveness and visual fidelity for gamers. It includes HGiG (HDR Gaming Interest Group) support for better HDR game rendering, and a very low input lag of around 9.1ms with Boost Mode activated, ideal for fast-paced gaming. A Game Optimizer menu simplifies the adjustment of gaming settings.
Running on LG's webOS, the B4 offers a user-friendly interface, smooth navigation, and a wide variety of apps. It also features Bluetooth connectivity for peripherals like controllers, enhancing gaming and media control experiences. The TV has received recent software updates, with the latest version 23.22.65 released in June 2025, ensuring ongoing feature improvements and stability.
The built-in sound system is serviceable but not outstanding, with limited bass and Dolby Atmos effects. Pairing with a good soundbar is recommended for an immersive audio experience.
### Summary
The LG B4 48-inch OLED TV stands out as a budget-friendly OLED with premium gaming features, including full HDMI 2.1 support for 4K@120Hz, VRR, ALLM, and Dolby Vision gaming. Its excellent picture quality and low input lag make it a top choice for gamers who want OLED performance without the high price tag. The smart platform (webOS) is robust and regularly updated, further enhancing usability. However, its brightness and built-in sound are not best-in-class compared to more expensive LG OLED models.
This combination of features and value makes the LG B4 an excellent option especially for gamers and OLED enthusiasts looking for affordability without major compromises. With its HDMI eARC socket for pairing external sound systems and the upgraded LG Alpha 8 AI Processor, the B4 48-inch TV offers a compelling package for those seeking a high-performing OLED monitor that fits on a desk.
