LG 49NANO85UNA NanoCell 85 Series 4K UHD TV Review: A Leap Forward in LED Picture Quality
The LG 49NANO85UNA, part of LG’s 2020 NanoCell 85 Series, is a 49-inch 4K Smart TV that promises to elevate the LED viewing experience with advanced NanoCell technology, AI-driven performance, and robust gaming features. Designed for cinephiles, sports enthusiasts, and gamers alike, this TV aims to bridge the gap between premium LED and OLED displays—without the premium price tag. Let’s dive into what makes this model stand out in a crowded market.
NanoCell Display: The Heart of Lifelike Visuals
At the core of the 49NANO85UNA is LG’s proprietary NanoColor technology, which leverages nanoparticles integrated into the display to filter out dull colors and enhance purity. This results in a natural, lifelike color palette that avoids the oversaturation common in standard LED panels. The Real 4K NanoCell Display boasts over 8.3 million active pixels, delivering four times the resolution of Full HD—ideal for streaming 4K content from Netflix, Disney+, or Apple TV+.
Complementing NanoColor is Nano Accuracy, which ensures consistent color fidelity even at wide viewing angles (up to 178 degrees). This is a significant upgrade over conventional LED TVs, where colors often wash out when viewed off-center. Whether you’re hosting a movie night or catching a football game with friends, the picture remains vivid and uniform.
Local Dimming: Precision Contrast for Deeper Blacks
Unlike edge-lit LED TVs, the 49NANO85UNA employs Local Dimming, which dynamically adjusts backlighting across specific zones of the screen. This balances brightness and shadow in real-time, enhancing contrast and delivering deeper blacks—a critical feature for dark scenes in films or games. While not as granular as OLED’s per-pixel dimming, the result is still impressive for an LED panel, reducing halo effects and preserving detail in shadows.
AI-Powered Performance: The α7 Gen 3 Processor
The TV’s α7 Gen 3 Processor 4K is the brains behind its seamless performance. Leveraging AI Picture and AI Sound, the processor analyzes content frame-by-frame to optimize clarity, color, and contrast. For lower-resolution content, 4K Upscaling sharpens details and minimizes noise, ensuring even older DVDs or HD streams look crisp on the 4K display.
AI Sound, meanwhile, adapts audio based on content type (e.g., dialogue-heavy dramas vs. bass-heavy action scenes) and uses virtual surround technology to simulate a multi-dimensional soundscape. While built-in speakers won’t replace a dedicated soundbar, they’re surprisingly robust for everyday use.
Immersive Dolby Vision IQ & Dolby Atmos
The TV supports Dolby Vision IQ, an intelligent HDR format that adjusts brightness and contrast based on ambient lighting and genre-specific metadata. Whether you’re watching a sun-drenched nature documentary or a dimly lit thriller, Dolby Vision IQ ensures optimal HDR performance without manual tweaking.
For audio, Dolby Atmos creates a convincing illusion of height and depth, making explosions, rain, or orchestral scores feel immersive. Combined with AI Sound, the audio experience is cinematic for a TV of this size.
Smart Features: webOS & Magic Remote – Simplicity Redefined
The 49NANO85UNA runs LG’s webOS platform, one of the most intuitive smart TV interfaces available. It aggregates content from popular apps like Netflix, Prime Video, HBO Max, and YouTube into a sleek, customizable dashboard. The platform’s AI-powered recommendation engine suggests new content based on viewing habits, streamlining discovery.
The Magic Remote is equally impressive, combining voice control, motion gestures, and a scroll wheel for effortless navigation. Use voice commands via Alexa Built-in to search for titles, adjust volume, or control smart home devices—or simply point and click like a laser pointer. The remote’s ergonomic design and minimal button layout keep the experience clutter-free.
Gaming Optimization: Speed Meets Fluidity
Gamers will appreciate the TV’s HDMI 2.1-ready ports (though not fully confirmed in the 2020 model), which support Auto Low Latency Mode (ALLM) and variable refresh rate compatibility for smoother gameplay. Input lag is minimized, making fast-paced titles like Call of Duty or Fortnite feel responsive. The combination of Local Dimming and 4K resolution ensures vibrant visuals with minimal motion blur—critical for competitive gaming.
Design & Connectivity
The 49NANO85UNA sports a minimalist design with slim bezels and a versatile stand, fitting seamlessly into modern living rooms. Connectivity options include:
- Wi-Fi & Bluetooth: Wireless streaming and peripheral pairing.
- HDMI & USB Ports: For consoles, soundbars, or external drives.
- Wireless Surround Sound Compatibility: Pair with compatible LG speakers for expanded audio.
Notably, the TV ships with a remote control, power cable, and e-manual, ensuring quick setup.
Who Is This TV For?
The LG 49NANO85UNA is ideal for:
- Movie Buffs: NanoColor and Dolby Vision IQ deliver cinematic HDR.
- Gamers: Low input lag and 4K clarity enhance next-gen console gaming.
- Casual Viewers: webOS and Alexa streamline daily entertainment.
- Small to Mid-Sized Rooms: The 49-inch size suits apartments or bedrooms.
Limitations to Consider
While the NanoCell 85 excels in most areas, its Local Dimming can’t match OLED’s infinite contrast, and peak brightness falls short of QLED rivals like Samsung. The 60Hz refresh rate (without confirmed HDMI 2.1) may deter hardcore gamers seeking 120Hz support.
Final Verdict: A Premium LED Experience
The LG 49NANO85UNA NanoCell 85 Series redefines what mid-tier LED TVs can achieve. Its NanoColor accuracy, Local Dimming, and AI-enhanced processor create a visually stunning experience, while Dolby Atmos and Vision IQ add cinematic flair. For those seeking OLED-like color fidelity without the OLED price—or gamers prioritizing responsive 4K gameplay—this TV is a compelling choice.
Though not flawless, it’s a testament to LG’s innovation in LED technology, blending smart features, immersive audio, and razor-sharp visuals into a sleek, accessible package. If you’re upgrading from a 1080p TV or an older 4K model, the NanoCell 85 Series delivers a transformative step up—one that justifies its place at the forefront of 2020’s LED lineup.
