This TV does not merely raise the standard for picture display; it is also designed to meet the demands of those seeking a premium entertainment experience, whether for watching movies, gaming, or general daily use.

Specifications and Real-World Functionality

Neo QLED and Mini LED Technology: A New Dimension of Brightness and Contrast

At the heart of the Samsung QN90D is Neo QLED technology combined with Mini LEDs, which are 40 times smaller than conventional LEDs. This allows for precise backlight control across numerous local dimming zones, resulting in vivid contrast, flawless deep blacks, and stunning brightness while fully preserving details in both dark and bright areas. This micro-level light management effectively reduces blooming, giving the picture unprecedented dimension and depth.

Neural Quantum Processor 4K: The Brilliance of AI

The QN90D is powered by the AI-driven Neural Quantum Processor 4K, which is the powerhouse behind its outstanding display performance. This processor utilizes 20 neural networks to analyze and optimize picture and sound quality in real time. Key standout functions include:

• **4K AI Upscaling:** Capable of upscaling the clarity of lower-resolution content to near-4K quality by intelligently analyzing and filling in missing pixels.
• **HDR Remastering:** Enhances the contrast and colors of SDR content to make it look as vibrant as HDR.
• **Scene Analysis:** Analyzes individual scenes to optimize brightness, color, and sharpness.
• **Real Depth Enhancer:** Adds depth to the picture by identifying the main subject and increasing the contrast around it.

The Ultimate Gaming Experience: Built for True Gamers

For gamers, the Samsung QN90D is a dream come true, packed with features designed specifically for gaming:

• **Up to 144Hz Refresh Rate (on select models/sizes):** Supports high-frame-rate gaming, delivering smooth, tear-free visuals—especially for PC games demanding peak performance.
• **4 HDMI 2.1 Ports:** Supports full HDMI 2.1 features such as 4K@120Hz, Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Enhanced Audio Return Channel (eARC)—perfect for next-gen consoles like the PS5 and Xbox Series X.
• **AMD FreeSync Premium Pro:** Prevents screen tearing and reduces stuttering, ensuring smooth gameplay even with fluctuating frame rates.
• **Game Bar:** An on-screen menu that gives gamers quick access to critical settings such as aspect ratio, input lag, or VRR without having to leave the game.
• **Motion Xcelerator Turbo Pro:** Minimizes motion blur in fast-paced scenes, ensuring maximum clarity.

Superior HDR Picture Quality and Vibrant Colors

The QN90D delivers an exceptional HDR experience with incredible peak brightness (exceeding 2,000 nits on select models/sizes), allowing details in the brightest highlights of HDR10+ content to stand out vividly. Combined with Quantum Dot technology that offers 100% Color Volume, colors are vibrant, lifelike, and accurate at all brightness levels. It also features Ultra Viewing Angle, ensuring the picture remains sharp and colors stay true even when viewed from the side.

Object Tracking Sound+ (OTS+): Immersive Audio Power

The OTS+ audio system is another standout feature that sets the QN90D apart. Built-in speakers placed around the screen work together to deliver sound that moves dynamically with the action on-screen, creating a more realistic and immersive soundstage. Whether it is the sound of a helicopter flying overhead or heavy rain pouring down, you can feel the precise direction of the audio, offering a deeply immersive viewing experience.

Smart TV Powered by Tizen OS: User-Friendly and Full-Featured

Samsung’s Tizen OS is highly intuitive, featuring a smooth interface and seamless access to all popular streaming applications. It supports voice commands via Bixby, Google Assistant, and Alexa. Additionally, versatile connectivity options, including Wi-Fi, Bluetooth, and Apple AirPlay 2, make connecting to other devices effortless.
