Picture Quality

The QN90B elevates picture quality to new heights with its innovative combination of Mini LED backlighting and Neo QLED technology. Here’s a breakdown of these advancements and their impact on your viewing experience:

  • Mini LED Backlighting: The QN90B utilizes Mini LEDs, significantly smaller than traditional LEDs used in backlighting. This allows for more precise control over individual lighting zones behind the screen. Imagine a starry night scene; Mini LEDs can dim specific zones, creating deeper blacks for the stars to truly shine against. The result? Enhanced contrast with inky blacks and brighter highlights for a more realistic and immersive picture.

  • Neo QLED Technology: Samsung’s Neo QLED technology combines Quantum Dot technology with the Mini LED backlighting. Quantum Dots are tiny nanoparticles that enhance color reproduction and viewing angles. Together, these technologies aim to deliver a more vibrant, realistic, and immersive picture. Imagine a nature documentary; Neo QLED technology strives to showcase the full spectrum of colors with exceptional detail, bringing the natural world to life on your screen.

The QN90B supports High Dynamic Range (HDR) formats like HDR10, HDR10+, and HLG, ensuring compatibility with most HDR content. HDR offers a wider range of colors and brightness compared to standard definition content, further enhancing the viewing experience. Imagine a scene with an explosion; HDR allows for incredibly bright highlights without sacrificing detail in the shadows, creating a more realistic and visually impactful experience.

Sound Quality

The QN90B features a built-in 2.0 channel sound system that delivers decent audio quality for everyday viewing. However, due to the TV’s slim design, the speakers might not offer the most powerful or immersive sound experience, especially for movies or music. Here’s a breakdown to consider:

  • Suitable for Casual Viewing: For casual TV shows, news broadcasts, or even gaming, the built-in speakers might be sufficient. They offer clear dialogue reproduction and decent audio quality for everyday use.

  • Limited Bass: The built-in speakers might struggle to reproduce deep bass, which can be important for an immersive movie experience or music with strong bass lines. Imagine an action movie with a car chase; the deep rumble of the engines might be less impactful.

  • External Options for Enhanced Audio: The QN90B offers various options for connecting external sound systems, including HDMI ARC (Audio Return Channel) and optical digital output. This allows you to connect a soundbar or home theater system for a more impactful and immersive audio experience. Imagine watching a concert; a soundbar or home theater system could create a more room-filling and realistic soundscape, transporting you to the heart of the performance.


The Samsung QN90B goes beyond exceptional picture quality, offering a robust feature set designed to cater to various entertainment needs and preferences. Here’s a look at some additional functionalities that enhance the overall user experience:

  • Gaming Features:

    • Auto Low Latency Mode (ALLM): This feature is a boon for gamers. ALLM automatically detects when a gaming console is connected and optimizes the TV’s settings for the lowest possible input lag. This translates to a more responsive gaming experience, where your actions on the controller are reflected on the screen with minimal delay. Imagine playing a twitch-based shooter game; ALLM can help ensure your reflexes and actions translate precisely in-game.

    • Motion Xcelerator Turbo+: This technology aims to minimize motion blur during fast-paced scenes, often encountered in racing games or action movies. Motion Xcelerator Turbo+ works by inserting additional frames between the original frames, creating a smoother and more visually fluid experience. Imagine a high-speed car chase; Motion Xcelerator Turbo+ can help maintain clarity and detail, even during rapid movements on the screen.

  • Smart TV Features:

    • App Selection: The Tizen smart TV platform offers a vast library of apps, catering to diverse interests. Popular streaming services like Netflix, Disney+, Hulu, HBO Max, and YouTube are all readily available. Additionally, the platform offers access to music streaming services, fitness apps, and even gaming apps, transforming your TV into a versatile entertainment hub. Imagine wanting to unwind after a long day; you can access your favorite streaming service, listen to music, or even follow a workout routine – all directly on your QN90B.

    • Multi-View: This feature allows you to split your TV screen and display content from two sources simultaneously. Imagine watching a sports game on one half of the screen while keeping an eye on live news updates on the other. Multi-View offers a convenient way to multitask and stay informed while enjoying entertainment.

  • Connectivity:

    • HDMI ARC (Audio Return Channel): This allows for a single-cable connection to compatible soundbars or AV receivers. With HDMI ARC, you can control the volume of your soundbar or receiver using the TV’s remote, simplifying your setup and eliminating cable clutter.

    • Wireless Connectivity: The QN90B offers built-in Wi-Fi and Bluetooth connectivity. This allows you to connect the TV to the internet for accessing streaming services and smart features. Additionally, Bluetooth connectivity lets you wirelessly stream music from your smartphone or other Bluetooth-enabled devices, offering a convenient way to play music through your TV’s speakers.

These are just some of the key features that the Samsung QN90B boasts. The combination of a powerful smart TV platform, gaming-centric features, and versatile connectivity options aims to create a comprehensive entertainment experience that caters to movie buffs, gamers, and casual viewers alike.


The Samsung QN90B Neo QLED 4K Smart TV positions itself as a top-tier contender in the home entertainment arena. It boasts cutting-edge features like Mini LED backlighting and Neo QLED technology, delivering a visually stunning picture with deeper blacks, brighter highlights, and vibrant colors. The QN90B also offers a robust smart TV platform with access to popular streaming services, voice control capabilities, and gaming-centric features like ALLM and Motion Xcelerator Turbo+.

However, the decision to invest in the QN90B hinges on your budget and viewing priorities:

Ideal for:

  • Viewers seeking a top-tier TV experience with exceptional picture quality, a wide range of features, and a sleek design.
  • Movie enthusiasts who prioritize the most vibrant colors, deepest blacks, and brightest highlights for an immersive viewing experience.
  • Gamers seeking a TV with features like ALLM and Motion Xcelerator Turbo+ for a smooth and responsive gaming experience.

Consider alternatives if:

  • Budget is a primary concern: Less expensive 4K TVs might offer a very good viewing experience, especially for casual viewers. While they might not achieve the same level of contrast or brightness as the QN90B, they can still deliver a clear and crisp picture suitable for everyday viewing.
  • Sound quality is a major priority: While the QN90B’s built-in speakers are decent for casual viewing, they might not be ideal for movie buffs or music lovers seeking a truly immersive audio experience. Exploring options with better built-in sound systems or factoring in the cost of a separate soundbar might be preferable.
  • You don’t necessarily need the absolute cutting-edge features: If you primarily use your TV for watching shows or movies and don’t prioritize the absolute top-of-the-line features like Mini LED backlighting or the latest smart TV functionalities, a less expensive 4K TV might be sufficient.

The Samsung QN90B is a premium 4K TV with a stunning picture, a wide range of features, and a sleek design. However, its premium price tag might not be suitable for everyone. If you’re a discerning viewer who prioritizes exceptional picture quality and cutting-edge features, the QN90B is a compelling choice. But if you’re on a budget or don’t necessarily need the absolute top-of-the-line features, exploring less expensive 4K TV options might provide a very good viewing experience that meets your needs. Ultimately, the best choice depends on your individual needs and budget.
