In LG’s OLED lineup, the G-series represents the pinnacle of 4K picture performance — sitting above the C-series models. In 2024, the LG G4 stood proudly as one of the brightest and most refined OLED TVs available, positioned above the LG C4. For 2025, LG continues the legacy with the new LG G5, which now sits above the LG C5, introducing improvements in brightness, gaming capabilities, and overall processing refinement.
Both the LG G4 and LG G5 are designed for enthusiasts who demand top-tier performance, cutting-edge design, and long-term durability. However, while they share much of the same DNA, LG has made subtle but meaningful upgrades that push the G5 even closer to perfection. In this article, we’ll compare both models in detail to highlight what’s truly improved — and help you decide whether it’s worth moving up to the G5.
LG G5 (2025) Short Overview
The LG G5 represents the next evolution of LG’s premium “Gallery” OLED lineup. It continues to refine the minimalist One Wall Design that allows the TV to sit flush against the wall for a truly artistic look. Available in sizes ranging from 55 to 97 inches, the G5 also includes the wall-mount kit in the box — ensuring it’s ready for installation right out of the package.
At the heart of the G5 lies the new α11 AI Processor Gen2, which improves upon last year’s version with faster scene-by-scene analysis, more advanced AI tone mapping, and smarter upscaling. This translates into better detail recovery and improved shadow and highlight control in HDR content. It also makes the G5 more efficient at managing motion and color precision for various sources — from 4K Blu-ray to streaming content.
In terms of brightness, the G5 introduces Brightness Booster Max (or Ultimate) paired with a new four-stack OLED panel that achieves higher luminance than the G4. Early measurements show peak HDR brightness exceeding 2000 nits — a major leap for OLED technology. This makes the G5 significantly better suited for bright rooms while retaining the perfect blacks OLEDs are known for.
Gamers will also appreciate the upgrade to 165 Hz refresh rate support, available across all four HDMI 2.1 ports with full bandwidth (48 Gbps). Variable Refresh Rate (VRR), NVIDIA G-Sync, AMD FreeSync Premium, and Auto Low Latency Mode (ALLM) are all supported. Combined with LG’s Game Optimizer and minimal input lag, this makes the G5 one of the best gaming TVs available in 2025.
Rounding out the experience is webOS 25, which offers a cleaner interface, personalized profiles, and access to all major streaming services. The G5 supports Dolby Vision IQ, HDR10, and Dolby Atmos, ensuring top-tier cinematic performance for both movies and series.

LG G4 (2024) Short Overview
The LG G4 remains a stunning OLED TV that redefined what high-end home viewing could be in 2024. It was the first LG OLED to use the Micro Lens Array (MLA) technology, which improved brightness over previous generations by focusing more light toward the viewer. Combined with LG’s α11 AI Processor, it offered excellent picture clarity, contrast, and motion precision.
The G4’s design also reflected its premium positioning, featuring the slim Gallery Design that allowed for wall-mounting without gaps. Build quality is exceptional, and the bezel is nearly invisible, giving the panel a floating appearance that blends seamlessly with modern interiors.
For picture performance, the G4 excelled in delivering perfect blacks, vivid colors, and high HDR accuracy across all major formats. It performed exceptionally well in dark environments and provided a very bright image for an OLED — though still slightly behind what the newer G5 achieves.
Gamers found plenty to love, with four HDMI 2.1 ports, 120 Hz to 144 Hz refresh rate, VRR, ALLM, and G-Sync/FreeSync support. Combined with incredibly low input lag, the G4 was already considered one of the best gaming OLEDs of its time.
In short, the G4 remains a formidable performer that still rivals most 2025 OLEDs in real-world performance, making it a smart buy for those who want premium picture quality without stretching their budget to the latest model.

The Differences Between LG G5 and G4
Although the LG G4 and G5 share the same design philosophy and processing family, LG has introduced several meaningful improvements in the newer G5 model:
- Brightness and Panel Technology – The G5 achieves significantly higher peak brightness thanks to its four-stack OLED panel and Brightness Booster Ultimate system, resulting in punchier highlights and more visibility in well-lit rooms.
- Higher Refresh Rate – The G5 now supports up to 165 Hz for PC and next-gen gaming, offering smoother motion and even lower latency compared to the G4’s 144 Hz ceiling.
- Processor Upgrade – The α11 AI Processor Gen2 brings improved AI tone mapping, upscaling, and scene analysis, giving the G5 more accurate HDR rendering and better noise reduction.
- Software and Interface – The G5 ships with the latest webOS 25, offering a refreshed interface, multi-user profiles, and improved voice navigation.
- Design and Accessories – The G5 continues the flush-mount design but now includes the wall-mount kit as standard, while the G4 often required separate purchase depending on region.
