When exploring LG’s 2025 OLED TV lineup, two models often appear side-by-side — the LG C5 and the LG B5. They are both positioned below the flagship LG G5. Both deliver the stunning picture quality that OLED technology is known for: perfect blacks, infinite contrast, and vivid color reproduction. However, they cater to slightly different audiences based on performance, processing power, and budget.
In this comparison, we’ll break down exactly how the LG C5 and LG B5 differ — from their panels and processors to gaming capabilities and real-world performance — so you can confidently decide which model fits your viewing style best.
LG C5 Short Overview
The LG C5 stands as a mid-to-upper-tier model in LG’s 2025 OLED lineup. It features an OLED evo panel powered by the new α9 AI Processor Gen8, offering excellent peak brightness, refined color mapping, and more accurate tone control than its predecessors. Designed to perform well in both dark and bright environments, the C5 is also labeled “Bright Room Ready,” meaning it’s built to handle reflections and ambient light better than typical OLEDs.
Picture quality is among the best in its class — combining rich contrast, deep black levels, and natural-looking color balance that’s ideal for both cinematic and casual viewing. HDR performance is particularly strong, producing punchy highlights and excellent depth even in daylight conditions.
For gamers, the C5 is a true powerhouse. It supports up to 144 Hz refresh rate, 0.1 ms response time, and four HDMI 2.1 ports, along with full support for NVIDIA G-Sync, AMD FreeSync Premium, and VRR. Whether connected to a gaming PC or a next-gen console, motion remains buttery smooth with minimal input lag.
Available in 42-, 48-, 55-, 65-, 77-, and 83-inch screen sizes, the LG C5 blends flagship-level performance with a sleek, wall-friendly design that suits any modern living room.

LG B5 Short Overview
The LG B5 serves as the more affordable entry in LG’s 2025 OLED family. It uses a standard OLED panel (non-evo) and runs on the α8 AI Processor Gen2, which still delivers strong image clarity, detailed upscaling, and accurate color — though it doesn’t quite reach the brightness levels or processing refinement of the C5.
Despite being positioned as the “entry-level OLED,” the B5 maintains impressive gaming capabilities. It supports 120 Hz refresh rate, VRR, ALLM, and four HDMI 2.1 ports. Importantly, it’s also G-Sync Compatible and supports AMD FreeSync Premium, ensuring a smooth, tear-free gaming experience across a wide variety of systems.
In typical viewing, the B5’s perfect blacks and infinite contrast still make it a cinematic standout — especially in dark or dim environments. However, its lower peak HDR brightness means it performs best in controlled-lighting conditions rather than bright, sun-filled rooms.
With screen sizes ranging from 48 to 83 inches, the LG B5 offers a genuine OLED experience with all the essential modern features — at a price point that’s easier to reach.

The Differences Between LG C5 and B5
While both share the same OLED DNA and smart platform, several key factors set them apart:
- Panel Technology
The C5 uses an OLED evo panel, producing higher brightness and improved efficiency. The B5’s standard OLED panel lacks this enhancement, resulting in lower peak brightness. - Processing Power
The C5’s α9 AI Gen8 processor offers more advanced image refinement and upscaling. The B5’s α8 Gen2 is capable but slightly less powerful, especially for HDR tone-mapping and lower-resolution content. - Refresh Rate and Gaming Performance
The C5 supports up to 144 Hz for ultra-smooth gaming on PC or next-gen consoles. The B5 tops out at 120 Hz — still excellent, but less future-proof. - Brightness and Room Suitability
The C5 shines in bright rooms thanks to higher peak brightness and reflection handling, while the B5 performs best in darker spaces. - Value and Price Positioning
The B5 delivers true OLED quality at a lower cost, whereas the C5 justifies its premium with better processing, higher brightness, and advanced gaming flexibility.
Final Verdict: Why the LG C5 Stands Out?
If you’re looking for the more complete and future-ready OLED TV, the LG C5 is the clear winner. It combines the enhanced OLED evo panel, faster 144 Hz refresh rate, and the top-tier α9 AI Gen8 processor, offering superior HDR brightness, refined motion, and cleaner upscaling across all content types. It’s the better choice for bright living rooms, large viewing spaces, and serious gamers who want the smoothest, most responsive experience possible.

That said, the LG B5 remains an outstanding option for those who mainly watch in darker rooms or prefer to save on cost without sacrificing OLED picture quality. It still supports G-Sync Compatible, FreeSync Premium, and VRR, making it a great performer for both gaming and movie watching. While it lacks the extra brightness and higher refresh ceiling of the C5, it delivers almost the same OLED visual excellence at a more approachable price.
