LG’s OLED lineup continues to evolve each year, bringing subtle but meaningful improvements in brightness, processing, and smart features. The LG C4 (2024) set a high bar as one of the most balanced OLED TVs in its class, while the LG C5 (2025) refines that success with a new processor, enhanced brightness, and longer software support.
Positioned above the LG B5 and below the LG G5, the LG C5 sits at the heart of LG’s 2025 OLED family — offering premium picture quality and gaming features without the flagship price tag. On the other hand, the LG C4 remains an excellent value choice from the previous generation. In this article, we’ll break down exactly how the two differ and help you decide which model fits your needs best.
LG C5 (2025) Short Overview
The LG C5 represents LG’s latest evolution of the C-series — refining everything that made the C4 great while adding meaningful enhancements for 2025. It’s powered by the new α9 AI Processor Gen 8, which delivers improved AI scene detection, more precise tone mapping, and faster response across menus and image rendering.
A major step forward this year is the inclusion of Brightness Booster technology, which increases peak luminance and enhances performance in bright-room environments — a feature previously exclusive to the G-series. Combined with LG’s OLED evo panel, it produces spectacular contrast, rich color depth, and superior clarity in both dark and well-lit rooms.
For gamers, the C5 remains one of the most complete options available. It supports 4K at up to 144 Hz, has four full-bandwidth HDMI 2.1 ports, and includes VRR, G-Sync, and FreeSync Premium for ultra-smooth gameplay. Its updated webOS 25 platform brings faster navigation, a cleaner layout, and extended software support for future updates.
In LG’s 2025 OLED hierarchy, the C5 stands above the B5 and below the G5, balancing high-end performance with excellent long-term value.

LG C4 (2024) Short Overview
The LG C4 continues to be a standout choice for those who value pure OLED picture quality and a proven performance track record. Powered by the α9 AI Processor Gen 7, it delivers beautiful contrast, accurate color tones, and excellent motion handling. The OLED evo panel provides deep blacks and cinematic image depth, making it perfect for dark-room viewing.
However, unlike the newer C5, the C4 does not include Brightness Booster technology, meaning its peak brightness is slightly lower — though it still performs impressively under typical indoor lighting. The C4 features four HDMI 2.1 ports, 4K @ 144 Hz support, and all major gaming features like VRR, G-Sync, and FreeSync Premium.
With webOS 24, it remains smooth, intuitive, and well-integrated with popular streaming platforms. Available in 42″, 48″, 55″, 65″, 77″, and 83″, the C4 still represents incredible value for anyone looking for an OLED that balances affordability with top-tier quality.

The Differences Between LG C5 and C4
While both models share the same OLED evo foundation and outstanding gaming support, several meaningful distinctions set them apart:
- Processor Upgrade — The C5 features the newer α9 Gen 8 processor, which improves tone mapping, upscaling accuracy, and overall responsiveness.
- Brightness Booster — Exclusive to the C5, this feature delivers higher peak brightness for better performance in daylight or bright-room conditions.
- Panel Efficiency — The C5’s OLED evo panel is more power-efficient and thermally optimized, allowing for higher sustained luminance.
- Smart Platform — The C5 runs on webOS 25, offering a cleaner interface, improved speed, and extended update support compared to webOS 24 on the C4.
- Price and Value — The C4 remains the more affordable option, offering similar picture quality and gaming features for less.
Why is LG C5 a Better Choice?
The LG C5 stands out as the better choice if you’re after the latest refinements in OLED performance. With its α9 Gen 8 processor, Brightness Booster technology, and webOS 25 platform, it delivers smoother HDR tone mapping, brighter visuals, and a faster, more intuitive smart experience. It also benefits from longer software support and sits in the perfect sweet spot between the B5 and G5 — offering near-flagship quality at a lower cost. For buyers who value brightness, responsiveness, and longevity, the LG C5 is the superior option for 2025.

However, the LG C4 still holds remarkable value as a proven performer. It offers nearly identical gaming features, the same 4K 144 Hz capability, and outstanding OLED picture quality at a more approachable price point. If you mostly watch content in dim lighting and prefer saving a few hundred dollars without sacrificing much in visual quality, the LG C4 remains an excellent alternative that continues to compete strongly in 2025.
