LG G4 OLED Review

LG G4 OLED Review: The Ultimate 2025 OLED TV That Sets New Standards

The LG G4 OLED Review reveals why this flagship television stands as one of 2025’s most impressive displays. After spending three weeks testing every aspect of this premium OLED TV, I can confidently say the G4 delivers exceptional picture quality, gaming performance, and smart features that justify its premium price point.

Is the LG G4 OLED Bright Enough for Daytime Viewing?

The LG G4 OLED reaches a peak brightness of 1,600 nits — the highest of any OLED TV in its class. In a dark or dimly lit room, this is more than enough to make HDR content look spectacular, with highlights that genuinely pop. However, peak brightness only applies to a small 10% window of the screen. Full-screen brightness drops to around 170 nits, which becomes noticeable in a sunlit living room. In mixed lighting — curtains half open, lamps on — the G4 holds up well and most viewers will be satisfied. But in a room with large windows and direct afternoon sunlight, Mini LED televisions like the Hisense U8N (3,000 nits) and Samsung QN90D (2,500 nits) will look significantly punchier and more vivid. The bottom line: if you watch mostly in the evenings or in a controlled lighting environment, the LG G4’s brightness is excellent and its OLED contrast will beat any Mini LED. If your living room gets flooded with daylight, a Mini LED TV will serve you better.

LG’s G4 OLED represents a significant leap forward from its predecessor. The combination of second-generation MLA technology, the powerful Alpha 11 AI processor, and enhanced brightness capabilities creates a viewing experience that’s simply stunning.

Quick Verdict: Should You Buy the LG G4 OLED?

Rating: 9.2/10

The LG G4 OLED excels in nearly every category. Its brilliant picture quality, excellent gaming features, and sleek design make it a top choice for discerning buyers. While the price is steep, the performance and future-proofing justify the investment.

Best For: Home theater enthusiasts, serious gamers, and anyone wanting the best OLED technology Skip If: Budget is tight, or you don’t need premium features

LG G4 OLED Design and Build Quality

Premium Aesthetics Meet Practical Function

The G4’s design immediately catches attention. Unlike typical ultra-thin OLED panels, LG increased thickness to just over half an inch. This might sound like a step backward, but it’s actually brilliant engineering.

The added thickness provides several benefits:

• • Enhanced stability reduces wobbling and safety concerns

• • Elegant silver band around the edges creates a jewelry-like appearance

• • Improved thermal management keeps the display running cooler

• • Better port accessibility makes connections easier

At 56.7 x 32.5 inches and 52.5 pounds (65-inch model), the G4 maintains an impressive presence without feeling bulky.

Stand Innovation Finally Gets It Right

LG fixed a major complaint from the G3 generation. The G4 includes a well-designed stand that offers:

• • Dual height options – Position screen close to surface or leave room for soundbar

• • Wide stability base extends forward and backward

• • Built-in cable management keeps wires organized

• • Quick assembly takes just minutes to set up

For wall mounting, the proprietary system creates virtually no gap between TV and wall, maintaining that “gallery” aesthetic the G-series is known for.

Picture Quality Performance

MLA Technology Delivers Stunning Brightness

The second-generation Micro Lens Array (MLA) technology represents the G4’s biggest advancement. These microscopic lenses sit above each OLED pixel, directing more light toward viewers.

Real-world impact:

• • Peak brightness: Up to 1,488 nits (10% window)

• • Improved HDR performance makes highlights pop

• • Better daylight viewing reduces glare issues

• • Enhanced color accuracy across all brightness levels

Alpha 11 AI Processor: Intelligence Meets Performance

LG’s new Alpha 11 chip brings significant processing improvements:

AI Scene Detection:

• • Automatically optimizes settings for content type

• • Recognizes faces, text, and objects for better clarity

• • Adjusts brightness and contrast in real-time

Upscaling Excellence:

• • 1080p content looks remarkably close to native 4K

• • AI fills in missing detail intelligently

• • Reduces compression artifacts effectively

HDR Support: Almost Complete Coverage

The G4 supports three major HDR formats:

• • HDR10 – Universal standard

• • Dolby Vision – Premium dynamic metadata

• • HLG (Hybrid Log Gamma) – Broadcast standard

Missing: HDR10+ support due to LG’s commitment to Dolby Vision

Color Performance Analysis

Technical Measurements:

• • Rec. 2020 Coverage: 72.9% (good)

These numbers translate to incredibly lifelike colors across all content types.

Low Latency Gaming Excellence
