When we talk about 4K OLED TVs in 2025, two models that deserve top mention are LG G5 and LG C5. Both are part of LG’s 2025 OLED lineup, bringing refinements in brightness, processing, and gaming performance over their predecessors.
The LG G5 is available in five screen sizes: 97-inch (OLED97G5WUA), 83-inch (OLED83G5WUA), 77-inch (OLED77G5WUA), 65-inch (OLED65G5SUB), and 55-inch (OLED55G5SUB). Meanwhile, the LG C5 comes in six options: 83-inch (OLED83C5PUA), 77-inch (OLED77C5PUA), 65-inch (OLED65C5PUA), 55-inch (OLED55C5PUA), 48-inch (OLED48C5PUA), and 42-inch (OLED42C5PUA).
It’s clear from their naming that the LG G5 is positioned above the C5. But is it worth paying more? Let’s take a closer look at how they differ to help you decide which model suits you better.
LG G5 Short Review
The LG G5 steps in as the successor to last year’s G4, carrying forward the gallery-style design and introducing key upgrades under the hood. It uses an advanced OLED Evo panel enhanced with Brightness Booster Max and the new Micro Lens Array 2 (MLA2) technology, which further boosts peak brightness and efficiency. As with all OLED displays, the G5 achieves perfect black levels and infinite contrast, thanks to pixel-level dimming that lets every pixel control its own light output.
The OLED Evo panel also produces a wide color gamut with 100% color fidelity, ensuring accurate color reproduction across all shades. Wide viewing angles make it an excellent choice for group watching or bright living rooms.
Powering the LG G5 is the brand-new α11 AI Processor 4K Gen 2, which works with AI Super Upscaling 4K to deliver superior detail and clarity from any source. The upgraded processor improves color mapping, depth control, and real-time HDR tone balancing. The G5 supports Dolby Vision, HDR10, and HLG, so every HDR scene pops with vibrant realism.
In terms of motion handling, the G5 takes it up a notch with a native 165 Hz refresh rate. Combined with VRR (Variable Refresh Rate), ALLM, FreeSync, G-Sync, and HGiG, it’s ready for both console and PC gamers who demand lightning-fast responsiveness.
Running on webOS 25, the G5 provides a smoother and more customizable smart experience than before. It comes equipped with Wi-Fi 6E, which ensures faster wireless performance for 4K streaming and cloud gaming. Control options are versatile — including the Magic Remote, Google Assistant, Amazon Alexa, and Apple HomeKit/AirPlay 2.
Sound quality also receives an upgrade. The G5 integrates a 4.2-channel 60-watt audio system powered by α11 AI Sound Pro. It supports Dolby Atmos, WiSA, Bluetooth Surround Ready, and eARC, offering flexibility for high-quality sound setups.

LG C5 Short Review
The LG C5 continues the legacy of the hugely popular C-series as the direct successor to the C4.
It’s designed for those who want premium OLED performance without paying flagship prices. Like its sibling, it uses an OLED Evo panel that produces infinite contrast and perfect black through Pixel Level Dimming. The C5 also features Brightness Booster technology to enhance luminance, although not to the same level as the G5’s Max version. Color accuracy remains excellent, supported by Wide Color Gamut and Wide Viewing Angle performance for consistent tones from every seat.
Under the hood, the C5 is powered by the updated α9 AI Processor 4K Gen 8, delivering improved AI picture tuning, object recognition, and scene-by-scene enhancement. The α9 AI Super Upscaling 4K engine refines lower-resolution content to near-4K clarity. It also supports Dolby Vision, HDR10, and HLG for dynamic HDR presentation.
For motion and gaming, the C5 offers a native 144 Hz refresh rate — still extremely smooth and ideal for fast-action scenes or next-gen consoles. It’s also fully compatible with VRR, ALLM, FreeSync, G-Sync, and HGiG, ensuring tear-free gameplay.
The webOS 25 platform comes standard, bringing LG’s latest interface design, quicker app loading, and access to countless streaming services. The C5 supports Wi-Fi 5 for network connectivity and can be voice-controlled through Google Assistant, Alexa, or Apple HomeKit.
For sound, LG C5 is equipped with a 2.2-channel 40-watt speaker setup enhanced by α9 AI Sound Pro. While not as powerful as the G5, it still produces clean and balanced audio, and supports Dolby Atmos, WiSA, Bluetooth Surround Ready, and eARC for easy expansion.

The Differences Between LG G5 and C5
From the table above, we can identify several key distinctions between LG G5 and C5. Let’s break them down below.
- Brightness Enhancement
The biggest difference lies in the brightness system. LG G5 uses Brightness Booster Max with Micro Lens Array 2, while the C5 relies on the standard Brightness Booster. As a result, the G5 achieves noticeably higher peak brightness, producing more impactful HDR highlights and improved visibility in bright rooms.
- Picture Processor
The G5 is driven by the flagship α11 AI Processor 4K Gen 2, whereas the C5 runs on the α9 AI Processor 4K Gen 8. The α11 chip introduces stronger AI scene analysis and object recognition, resulting in more refined contrast control and detail accuracy.
- Refresh Rate and Gaming
While both TVs are superb for gaming, the G5 offers a slightly higher 165 Hz refresh rate versus 144 Hz on the C5. That extra headroom benefits competitive PC gamers and those who want the smoothest motion possible.
- Connectivity
LG G5 comes equipped with Wi-Fi 6E, which offers faster speeds and more stable data throughput compared to the Wi-Fi 5 connection of the C5. If you frequently stream high-bitrate 4K HDR content, the G5’s newer Wi-Fi standard will make a difference.
- Audio System
The G5 packs a more powerful 4.2-channel 60 W setup with α11 AI Sound Pro, while the C5 carries a 2.2-channel 40 W system. That means richer sound output and wider audio dispersion on the G5, ideal for larger living spaces.
- Price Range
Unsurprisingly, LG G5 commands a higher price across all sizes. It’s the premium choice in LG’s 2025 OLED family, while the C5 offers excellent performance at a lower cost. Checking current pricing is recommended, as retail offers often vary throughout the year.
Should You Choose LG G5?
So, should you go for LG G5? As the higher-end model, the G5 clearly delivers more — superior brightness, a faster processor, higher refresh rate, stronger sound, and newer connectivity features. If you’re after top-tier picture performance and cutting-edge features, the LG G5 is undoubtedly the model to pick. You’ll also benefit from richer audio and sleeker gallery design.

However, LG C5 remains a highly capable OLED that inherits many premium features from the G-series. Its slightly lower brightness and audio output are trade-offs for a much more approachable price. If you’re looking for top-class OLED quality on a tighter budget, the C5 will serve you exceptionally well.
