The LG 55" Class QNED75 is a 4K UHD Mini LED Smart TV featuring LG's QNED display technology, which combines Quantum Dot and NanoCell color science with Mini LED backlighting to deliver a wide color gamut and enhanced contrast. The display delivers a native 60Hz refresh rate at 3,840 x 2,160 resolution, and Dimming Pro dynamically adjusts backlighting to maintain deep black levels and minimize halo effects.

Powered by the α5 AI Processor Gen6, the TV performs AI-based 4K upscaling to sharpen lower-resolution content, adjusts picture contrast and color based on room lighting, and up-mixes 2-channel audio into virtual 5.1.2 surround sound via AI Sound Pro. Filmmaker Mode presents cinematic content exactly as directors intended, preserving the original frame rate and color grading. HDR support includes HDR10 and HLG formats.
