Overview
Key Features
QNED CONTRAST: TV entertainment never looked better, thanks to our Mini LED technology, for incredibly bright colors you can feel. Hundreds of miniature LED backlight zones operate independently, for movies with excellent dark-level detail and deep blacks, while minimizing halo effects.
QUANTUM DOT NANOCELL COLOR: Only LG Quantum Dot TVs add a nanocell layer that removes unwanted light for richer more colorful picture with extended contrast.
MINI LED BACKLIGHTING WITH PRECISION DIMMING: LG Precision Dimming controls MiniLEDs that are 40x smaller with thousands of dimming zones that can be individually controlled for better black levels and brighter colors.
DOLBY VISION, FILMMAKER AND DOLBY ATMOS: Experience the magic of the big screen right from your couch. LG QNED comes loaded with Dolby Vision for extraordinary color, contrast and brightness, plus Dolby Atmos* for wrap-around sound. Land in the center of the action with FILMMAKER MODE, allowing you to see films just as the director intended.
a8 AI PROCESSOR: Refined picture, powered by AI No more fiddling with picture settings. The a8 AI Processor 4K with AI Picture Pro identifies the type of content you're watching to automatically select the ideal setting and fine-tune the picture for the best watching experience and with Multi View with 2 screens lets you split your screen into two unique views so you can watch even more than before.

Pros & Cons
👍 Pros
- Mini LED with independent dimming zones delivers substantially better contrast than standard LED backlighting — dark scenes look genuinely cinematic.
- Quantum Dot NanoCell color layer produces rich, saturated colors without the green push some competing QLED panels exhibit.
- a8 AI Processor automates picture calibration so content looks good out of the box without manual tinkering.
- Dolby Vision and Dolby Atmos support means you get the best available HDR and audio from compatible streaming services.
- Alexa built-in eliminates the need for a separate voice assistant device.
👎 Cons
- Mini LED local dimming, while good, still produces some blooming around bright objects against very dark backgrounds — visible in high-contrast scenes like credits over black.
- The a8 processor sits a step below LG's flagship α9 chip, so AI upscaling and processing are capable but not best-in-class.
- At 75 inches, it requires a substantial wall mount or TV stand — factor in room size and furniture before purchasing.
- webOS smart platform, while user-friendly, includes pre-loaded apps and a content recommendation bar that some users find intrusive.
Frequently Asked Questions
Is the Mini LED backlighting on the QNED90T noticeably better than standard LED TVs?
Yes — and it's most apparent in dark scenes. Hundreds of independently controlled dimming zones let the TV produce deep blacks in shadow areas while keeping bright highlights bright at the same time. You won't get OLED-level black uniformity, but it's a clear step above edge-lit LCD sets.
Does the QNED90T support 4K 120Hz gaming?
The QNED90T runs a 120Hz native panel at 4K resolution, which supports high-frame-rate gaming from compatible sources. Check LG's HDMI specification for the specific port that carries the 4K/120Hz signal, as not all HDMI ports on the set are equal.
How does the a8 AI Processor handle upscaling of non-4K content?
The a8 processor applies AI-based upscaling to HD and FHD content, interpreting the source material and applying picture enhancements based on content type. Results vary — streaming at 1080p looks noticeably cleaner than it would on a basic upscaler, though native 4K content is still the optimal source.
How involved is the smart TV setup, and does Alexa require a separate device?
Setup through LG's webOS smart platform is straightforward — the guided setup walks you through Wi-Fi and streaming account connections in about 15 minutes. Alexa is built directly into the TV; no Echo or external device is required to use voice commands.
Is 75 inches too large for a standard living room?
For a typical viewing distance of 8–10 feet, 75 inches is right in the sweet spot for an immersive 4K experience — the resolution holds up at that size because 4K pixel density scales well to larger screens. Under 8 feet, some viewers find it overwhelming; over 10 feet, you start losing fine detail.
