Specs and performance comparison


The LG C4 is a high-end TV, and the brand boosts it with advanced AI features, a superior processor, and enhanced sound quality. These attributes set a clear boundary between the two, with the C4 designed to cater to a more enthusiastic audience. While the B4 is a more subtle TV; the entry-level panel offers a processor from a lower category which won’t have the AI boost other users might prefer.

The inclusion of the next-generation Alpha 9 AI processor in the C4 promises a more responsive and immersive viewing experience. This feature dynamically optimizes audio settings to match the content, ensuring an unparalleled auditory experience whether you’re watching movies, playing games, or streaming music. Both systems use the latest version of LG’s webOS 24 operating system and built-in Chromecast, which now seems to be a standard among the next gen of LG OLED TVs.

Furthermore, the LG C4 OLED distinguishes itself with a 144Hz refresh rate, a notable leap from the B4’s 120Hz. This specification is particularly enticing for gamers, offering smoother gameplay and an edge in fast-paced action that can be fully appreciated on high-performance PCs. 

Performance and brightness

The main distinction between the LG C4 and the LG B4 is the C4 featuring LG’s OLED Evo panel. This advanced panel technology sets the C4 apart, offering significantly enhanced brightness levels compared to the standard OLED panels found in the B4. Despite the absence of LG’s cutting-edge Micro Lens Array (MLA) technology, which is exclusive to the brand’s higher-tier G4 and W4 models for 2024, both the C4 and B4 stand out for their picture quality.

For viewers, this means the C4 is capable of delivering more vibrant images and a wider range of colors, making it particularly well-suited for brightly lit rooms or content with dynamic lighting conditions.

LG C4 OLED vs LG B4 – price

LG’s approach to the C4 OLED’s pricing showcases a commendable consistency, with little deviation from the C3’s cost. This strategy might suggest a focus on maintaining customer loyalty through predictable pricing. However, the B4’s pricing remains a mystery, fueling speculation that it could slightly exceed that of its predecessor, the B3, following LG’s pricing pattern.

48-inch $1,599

The introduction of 48-inch sizes in the B4 series adds an intriguing variable to the mix, especially since this size option was absent in the B3 lineup. The price point for this new size could play a crucial role in distinguishing B4’s value proposition, potentially offering a fresh alternative within LG’s OLED offerings.

Is the LG C4 better than the LG B4?

The C4 stands as the ideal option for the tech-savvy enthusiast or the high-end user who demands the latest in AI enhancements, superior refresh rates, and expansive size options. Its prowess extends from the living room to the gaming den, making it a perfect choice for those pushing the limits of their viewing and gaming experiences, especially with the exclusive 83-inch model for expansive setups and the compact 42-inch variant tailor-made for PC gaming.

On the other hand, the LG B4 positions itself as a more accessible entry into the OLED market without compromising on quality. It’s the go-to choice for the everyday user who seeks a reliable, high-performance TV for a range of activities from console gaming and binge-watching favorite shows to hosting karaoke nights. 


The B4 combines LG’s renowned picture quality with a price point that’s easier on the wallet, ensuring you don’t have to sacrifice a premium viewing experience for affordability. In sum, whether you’re drawn to the cutting-edge technology and versatility of the C4 or the balanced excellence and value of the B4, LG offers a tailored solution to elevate your home entertainment.
