Overview

The LG 55QNED85UQA combines two display technologies that address the core weakness of conventional LED TVs: color volume and contrast. Quantum Dot NanoCell color filtering extends the panel's color gamut beyond what standard white-LED backlighting can achieve, producing more saturated reds and greens that make HDR content look genuinely vibrant rather than just bright. The Mini LED backlighting system — using LEDs roughly 40x smaller than traditional LEDs — enables finer local dimming zones, which translates to deeper blacks and better separation between bright highlights and dark shadows in the same frame. The a7 Gen5 AI Processor 4K handles both upscaling for non-4K content and dynamic picture/sound adjustment, with Dolby Vision IQ adapting the HDR tone mapping in real time based on ambient light levels in your room.

For everyday use, the 120Hz refresh rate keeps motion smooth across sports, gaming, and action-heavy content, while Filmmaker Mode gives movie watchers a clean, processing-free presentation. The smart TV platform covers essentially every major ecosystem: Alexa, Google Assistant, Apple AirPlay 2, and HomeKit are all built in, meaning this TV fits into an existing smart home setup without requiring a separate streaming device. It is a well-rounded 55-inch 4K TV that sits meaningfully above the commodity LED tier in picture quality while stopping short of OLED pricing — the right call for living room or dedicated viewing room setups where a reliable, feature-complete upgrade from an older set is the goal.

Pros & Cons

👍 Pros

  • Mini LED backlighting with precision dimming delivers contrast that standard LED TVs at this size and price cannot match — dark scenes gain real depth without crushing shadow detail.
  • Quantum Dot NanoCell color technology produces wider color gamut coverage that makes HDR content look visibly more saturated and accurate than conventional LCD panels.
  • 120Hz native refresh rate benefits both cinematic motion handling and gaming performance on current-gen consoles.
  • Dolby Vision IQ and Dolby Atmos support covers the full premium streaming ecosystem — Disney+, Netflix, Apple TV+, and Prime Video all serve supported HDR and audio formats.
  • Alexa, Google Assistant, AirPlay 2, and HomeKit built-in means this TV integrates with virtually any smart home ecosystem without an external streaming box.

👎 Cons

  • Mini LED with precision dimming can still produce a mild halo effect around very bright objects on pure black backgrounds — it is reduced versus conventional LED but not fully eliminated as it would be on OLED.
  • The 2022 model year means this TV predates some of LG's improvements in gaming features and HDMI 2.1 port count available on newer QNED series — worth checking port specs if gaming is the primary use case.
  • webOS smart TV software, while capable, receives fewer streaming app updates than Roku or Fire TV-based platforms, and some niche streaming apps may be absent from the LG Content Store.
  • The a7 Gen5 AI processor's automatic sound and picture adjustments can occasionally over-process content in ways that require manual mode tuning to correct — not set-and-forget for all viewing scenarios.
  • At 55 inches, the Mini LED advantage in contrast is less dramatic at typical living room viewing distances than it would be at 65 inches or larger, where you sit closer relative to screen size.

Frequently Asked Questions

Standard LED TVs use a relatively small number of large LEDs behind the panel, which limits how precisely the TV can brighten bright areas while keeping dark areas truly dark. This TV uses LEDs approximately 40x smaller, packed in far greater density, allowing the dimming zones to be much smaller and more precise. The practical result is noticeably deeper blacks and better highlight detail when bright and dark content appear on screen simultaneously — think a night scene with a bright moon, or subtitles over a dark background.
Yes, the TV supports 120Hz which benefits PS5 and Xbox Series X games that output at 120fps. Verify HDMI 2.1 port availability on this model for 4K/120Hz gaming specifically, as not all HDMI ports on a TV support the full bandwidth required for 4K at 120fps — check the input labeling in the manual.
Filmmaker Mode disables all motion smoothing, sharpness enhancement, and real-time image processing to present content as the director graded it — with natural motion cadence and accurate colors. For movies and scripted TV, most videophiles strongly prefer it. For sports or live content, the standard or sports preset with motion enhancement active tends to look better.
Yes — AirPlay 2 is built into the TV's webOS smart platform, so you can mirror or cast directly from an iPhone, iPad, or Mac without any additional hardware. HomeKit integration also lets you add the TV to your Apple Home setup for voice and automation control through Siri.
It matters most for upscaling lower-resolution content — the processor uses machine learning to improve detail and reduce compression artifacts in 1080p and SDR streams, which is where most streaming services still deliver a portion of their catalog. For native 4K HDR content the source quality is the dominant factor, but the processor visibly improves non-4K material.
