SAMSUNG QN55Q70AAFXZA 55 inch TV: In-Depth Review and Customer Opinions

The Samsung QN55Q70AAFXZA is a 55-inch QLED 4K smart TV that was released in 2021. QLED (Quantum Dot LED) is Samsung's proprietary display technology that aims to provide brighter and more vivid colors compared to standard LED-LCD TVs.

The QN55Q70AAFXZA is from Samsung's 2021 Q70A series, which sits in the upper-midrange of their lineup. It offers premium features like quantum dot technology for enhanced color, full array local dimming for deep blacks, and powerful AI upscaling for improving lower resolution content.

As a newer 2021 model, the QN55Q70AAFXZA includes Samsung's latest innovations like support for HDMI 2.1 ports, an ultra-wide viewing angle, and new smart TV features. The TV runs Samsung's Tizen-based operating system and comes with the company's SolarCell remote, which can be recharged by indoor lighting.

Overall, the Samsung 55-inch Class Q70A QLED 4K Smart TV aims to deliver a high-end viewing experience with exceptional picture quality and smart connectivity in the popular 55-inch screen size. This review will take a deeper look at the TV's design, display performance, features, sound and more.

Design

The Samsung QN55Q70AAFXZA has an attractive and modern design with an exceptionally thin profile and slim bezels around the display.

The TV itself has a thickness of just 0.8 inches, making it one of the slimmest 55-inch TVs on the market today. The thin design gives it a light and airy aesthetic that blends into any home decor.

The bezels around the screen are incredibly narrow, just a few millimeters wide. This creates a nearly edge-to-edge display that looks far more immersive and high-end than many competing models with chunkier plastic bezels. The slim bezels draw attention directly to the vibrant QLED screen.

With its elegant thin build and barely-there bezels, the QN55Q70AAFXZA makes a sophisticated statement whether wall-mounted or placed on a media stand. The streamlined profile is uniquely suited to mounting flush to the wall like a framed painting. For those placing it on furniture, the thin design minimizes its footprint and visual presence.

Overall, the trim figure and refined borders give this 55-inch Samsung a spectacular silhouette perfect for modern spaces. It achieves an airy, futuristic look that feels far more advanced than many bulkier and bezel-heavy LED TVs.

While the Samsung QN55Q70AAFXZA features an impressively slim design, other models like the TCL 55S421 also offer a thin, minimalist aesthetic. With a panel depth of just 2.4 inches, the TCL 55S421 is one of the thinnest 55-inch TVs at its price point. It has slim bezels around the display for an expansive viewing area. The lightweight unit can be readily wall mounted or placed on a TV stand. With sleek contours and compact dimensions, the TCL 55S421 is an affordable option for those wanting a super-slim 55-inch TV to blend seamlessly into their living space.

In terms of aesthetics, both the Samsung QN55Q70AAFXZA and TCL 55S421 feature fashionable ultra-thin designs with trim bezels. The Samsung has a slightly thinner overall profile at 0.8 inches versus 2.4 inches on the TCL model. However, the TCL offers a huge value advantage by providing a comparably slender modern form factor at a fraction of the price. Those seeking to balance aesthetics and affordability may want to take a close look at the elegantly designed TCL 55S421.

Display Quality

The SAMSUNG 55-inch QN55Q70AAFXZA comes with a striking 55-inch QLED 4K display that offers a superior viewing experience. It utilizes Samsung's quantum dot technology, which produces over a billion shades of color. The TV supports 100% color volume for rich, vibrant, and lifelike colors that pop on the expansive screen.

With a 4K UHD resolution (3840 x 2160 pixels), the display packs in 8 million pixels for stunning clarity and fine details. Whether you're watching movies, gaming, or streaming content, the 4K capabilities ensure every scene looks sharp. Small details really come through and images appear true-to-life on the large 55-inch screen.

The Q70A utilizes a direct full array backlight system. This allows for precise backlighting control to boost the brightness in light scenes and deepen the blacks in dark scenes. The result is outstanding contrast between bright and dark areas of the picture for a truly cinematic experience.

Overall, the QLED display with quantum dot technology provides an exceptional level of detail, vivid accurate colors, and excellent contrast on the 55-inch screen. It's built for an immersive viewing experience with movies, sports, and gaming.

If you're looking for a more budget-friendly 55-inch 4K TV option, check out the Hisense 55A6H. This model still delivers 4K resolution and HDR support. It uses DTS Virtual:X audio technology for an immersive sound experience. The 55A6H utilizes a ULED display, which helps boost color, contrast, and brightness. While it doesn't quite match the elite picture quality of the Samsung Q70A, the Hisense provides solid performance and features at a lower price point. The 55-inch screen size is great for most living rooms and gaming setups. Overall, the Hisense 55A6H is a great alternative 55-inch 4K smart TV if you want to save some money compared to premium options.

When shopping for a new TV, screen size and resolution are key factors. 55-inch 4K models like the Samsung Q70A and Hisense 55A6H provide ample screen real estate for an immersive viewing experience. 4K resolution ensures you get stunning clarity and detail from the latest movies, shows, games, and more. Both LED TVs also support high dynamic range (HDR) for enhanced contrast and expanded color. This helps images pop with vivid, accurate color.

Display technology is another consideration when choosing a new 4K TV. The Samsung Q70A features an advanced QLED display with quantum dot technology. This allows it to produce over a billion color shades for exceptional picture performance. The Hisense 55A6H utilizes ULED technology, which still delivers solid color, contrast and brightness, but not quite at the same level as quantum dot displays. So if your budget allows, the Q70A is the superior choice, but the Hisense 55A6H is great for those looking for good 4K picture quality at a more affordable price point.

With smart TV capabilities, you can access popular streaming apps like Netflix, Hulu, Disney+, HBO Max and more. This allows you to watch all of your favorite shows, movies and content in stunning 4K quality. You can also use the TVs for gaming, with the Samsung Q70A featuring auto low latency mode for a super responsive gaming experience. Ultimately, both the Samsung and Hisense 55-inch 4K TVs are great options that deliver gorgeous visuals and smart connectivity. Choose the Samsung Q70A for the best picture quality or go with the more budget-friendly Hisense 55A6H to save some money.

HDR Support

The Samsung QN55Q70AAFXZA supports the latest high dynamic range formats like HDR10+ and HLG (Hybrid Log-Gamma).

HDR10+ is an enhanced HDR standard that uses dynamic metadata to optimize brightness levels on a scene-by-scene basis. This allows for finer highlight details and more precise contrast across the range of light and dark areas in the picture. The TV can read the changes in metadata and adjust brightness accordingly. Compared to standard HDR10 which uses static metadata, HDR10+ creates a more life-like viewing experience.

HLG is a newer HDR format developed for broadcasting that doesn't require metadata. It's easier to integrate into the broadcast workflow. The Samsung QLED is one of the few TVs that supports HLG HDR natively. This means you can enjoy HLG-encoded content from streaming services and Ultra HD Blu-rays. HLG also aims to create a more natural and realistic HDR image.

With support for both HDR10+ and HLG, the Samsung Q70A can display a wide range of HDR content. You'll be able to experience enhanced contrast, color and clarity that brings out fine details in the brightest and darkest areas of the picture. This results in images that look closer to real life.

Smart Features

The QN55Q70AAFXZA comes with Samsung's slick Tizen platform that provides quick access to apps, games, and streaming services. The intuitive interface makes navigating between different apps a breeze. You get access to popular streaming apps like Netflix, Hulu, YouTube, Apple TV, and more.

For voice control, the TV works with both Amazon Alexa and Google Assistant. You can use voice commands to launch apps, adjust settings, search for content, and more. The far-field mics do a good job of picking up voice commands from across the room.

One handy feature is Tap View, which lets you mirror your phone screen to the TV by just tapping the two devices together. This makes it super easy to share content from your mobile device. You also have screen mirroring capabilities for compatible smartphones.

Overall, the smart platform and features elevate the experience and make this TV extremely versatile for different types of entertainment and use cases. The ability to use voice control and cast content from mobile devices are very convenient capabilities.

Audio Quality

The 55" Samsung QN55Q70AAFXZA TV features impressive audio performance thanks to its 60W 4.2.2 channel speaker system. This provides a total power output of 60 watts, with two speakers placed on the left, two speakers on the right, and two woofers for bass - hence the 4.2.2 configuration.

The speakers deliver crisp and clear dialogue, allowing you to hear every word. Explosions and action sequences also pack a punch, with deep bass you can feel. The immersive surround-sound effect creates an engaging cinematic experience.

One of the highlights is Samsung's Q-Symphony technology. This allows the TV speakers and a compatible Samsung soundbar to work together simultaneously. Rather than disabling the TV speakers, Q Symphony combines audio from both sources for a more seamless and enveloping sound.

Overall, the built-in 4.2.2 speaker system produces room-filling, dynamic sound that outperforms the audio capabilities of most LED TVs. This makes it suitable for enjoying movies, TV shows, sports, and gaming without the need for an external sound system.

Ports and Connectivity

The Samsung QN55Q70AAFXZA TV comes with a strong selection of ports and connectivity options. This includes:

• 4 HDMI ports - The 4 HDMI ports allow you to connect multiple devices like Blu-ray players, gaming consoles, streaming sticks etc. All ports support HDMI 2.1 for high bandwidth.

• 2 USB ports - The USB ports allow you to plug in external devices like hard drives to play media files directly on the TV. One port is USB 3.0 for fast transfer speeds.

• Ethernet - For wired internet connectivity, there is a LAN port to connect to your home network with an ethernet cable. This provides faster and more reliable internet compared to WiFi.

• WiFi - For wireless connectivity, the TV has built-in WiFi support. It is compatible with the latest WiFi standards for fast internet speeds without any cables. You can easily stream content and mirror screens wirelessly.

• Bluetooth - Bluetooth allows you to pair wireless speakers, headphones and other peripherals with the TV. This gives you greater flexibility for your home theater setup.

With this great selection of connectivity options, the Samsung QN55Q70AAFXZA makes it easy to connect all your devices and access content conveniently. Both wired and wireless connections are fully covered.

Gaming Performance

The Samsung QN55Q70AAFXZA offers an excellent gaming experience thanks to its low input lag and VRR support.

Input lag refers to the time it takes for a TV to process and display image data from a source like a gaming console. Lower input lag results in a more responsive feel, which is critical for fast-paced games. This Samsung TV has an impressively low input lag of just 8.7ms in Game Mode. Actions feel instantaneous with barely any delay between pressing a button and seeing the result on screen.

VRR or variable refresh rate synchronizes the TV's refresh rate with the frame rate output of compatible gaming consoles or PCs. This eliminates screen tearing and stuttering for smoother gameplay. The QN55Q70AAFXZA supports VRR and AMD FreeSync for effortless gaming visuals when paired with a VRR-enabled device.

With these gaming enhancements enabling real-time interactivity and fluid visuals, the Samsung 55-inch 4K QLED TV delivers an exceptional high-performance gaming experience perfect for both casual and serious gamers.

Pros and Cons

Pros:

• Great picture quality - With a QLED display, this TV offers vibrant colors, deep blacks, and excellent contrast. The 4K resolution delivers a crisp, detailed image.

• Smart features - This TV comes with Samsung's Tizen smart platform, giving you access to popular streaming apps like Netflix, Hulu, Disney+, and more. It has voice controls through Bixby and Alexa.

• Thin design - The TV has an attractive slim profile that looks great mounted on a wall or on a TV stand. The thin bezels allow the screen to take center stage.

Cons:

• No Dolby Vision support - While it handles HDR10 and HDR10+, this TV lacks support for Dolby Vision HDR format. Some streaming services and 4K Blu-ray discs use Dolby Vision.

Conclusion

Overall, the Samsung QN55Q70AAFXZA is an excellent mid-range 4K TV that should satisfy most buyers looking for a 55-inch screen size. It delivers vibrant and accurate colors thanks to Samsung's quantum dot technology, deep blacks with its VA panel, and good brightness for fighting glare. Gamers will appreciate the low input lag and support for 120Hz refresh rates.

The smart TV platform is also highly capable, with access to all the major streaming apps and helpful features like auto low latency mode. Connectivity covers the essentials with 4 HDMI ports and 3 USB inputs.

That said, it does lack more advanced features like Dolby Vision support. So those wanting the very best HDR format may want to look at other options. But for the price, the Q70A provides stellar picture quality and is easy to recommend for mixed usage with movies, TV shows, sports, and gaming. Overall, it hits the sweet spot for a mid-range 55-inch 4K TV.
