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

• Rec. 709 Coverage: 98.5% (very good)

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