55 Inch Class LG QNED AI Mini LED QNED75B 4K Smart TV 2026

Product Description:

The LG 55-Inch QNED AI QNED75B (55QNED75BUA) is a 2026-model Mini LED 4K smart TV that brings LG's precision Mini LED backlighting, Dynamic QNED Color with certified 100% Color Volume, Dolby Vision, Dolby Atmos, and the α7 AI Processor 4K Gen9 to the most versatile living room screen size. At 55 inches, the QNED75B fits comfortably in living rooms, family rooms, bedrooms, and multi-purpose spaces while still delivering the immersive viewing experience and cinematic HDR performance that smaller screens struggle to provide. The QNED75B sits one tier above the 74B in LG's 2026 QNED lineup, adding Dolby Vision and Dolby Atmos support, a third HDMI input with eARC passthrough, Apple AirPlay and Google Cast, Dynamic Tone Mapping, and FILMMAKER MODE with Ambient Light Technology — meaningful upgrades that justify the step up for buyers who want a more complete cinematic package.

The Mini LED backlight packs thousands of tiny LEDs into dimming zones that can be controlled with far greater precision than traditional LED panels, allowing the TV to brighten highlights and darken shadows on a zone-by-zone basis. On a 55-inch display, Mini LED's precision dimming enhances every type of content — dark movie scenes reveal shadow detail instead of washed-out gray, bright HDR highlights pop with intensity and clarity, and the overall image gains a sense of depth and dimension that standard LED panels at this size simply cannot match.

Dynamic QNED Color delivers certified 100% Color Volume to the DCI-P3 color space, ensuring vivid, accurate color reproduction that maintains its saturation across the entire brightness range. Dolby Vision — the industry's leading HDR format — adds dynamic scene-by-scene and frame-by-frame metadata that optimizes brightness, contrast, and color for every moment of supported content from Netflix, Disney+, Apple TV+, and other Dolby Vision sources. Dolby Atmos creates immersive spatial audio through the TV's built-in speakers, placing sounds above and around you for a cinematic listening experience without a soundbar. Together, Dolby Vision and Dolby Atmos deliver the sight-and-sound quality that the QNED74B's HDR10 Pro alone cannot match. Dynamic Tone Mapping further refines HDR performance by adapting brightness and color gradation in real time.

The α7 AI Processor 4K Gen9 continuously analyzes on-screen content and automatically optimizes picture quality — enhancing textures, reducing noise, improving contrast, and upscaling lower-resolution content to near-4K clarity with AI Super Upscaling 4K. FILMMAKER MODE with Ambient Light Technology preserves the director's original creative intent while automatically adjusting picture settings based on your room's ambient lighting conditions — the director's vision adapts to your environment instead of requiring you to darken the room. AI Sound creates immersive virtual surround from the built-in speakers.
