The Samsung QA55S90DAUXZN, or the S90D as it’s more commonly known, is a 55-inch OLED marvel boasting the new NQ4 AI Gen2 processor and a host of smart features. Over the past few weeks, I’ve put this TV through its paces, subjecting it to everything from streaming 4K content to intense gaming sessions. This review will provide an honest assessment of its strengths and weaknesses.

The S90D is packed with features designed to elevate your viewing experience. The NQ4 AI Gen2 processor, with its 20 AI neural networks, is a standout. It upscales content beautifully, delivering a noticeably sharper and more detailed 4K picture even with lower-resolution sources. OLED HDR+ further enhances the image, producing stunning contrast and vibrant colors. The Tizen OS is intuitive and user-friendly, providing quick access to a wide array of streaming services, including Netflix, YouTube, Disney+, and many more. The built-in SmartThings Hub allows for seamless integration with other smart home devices.

Picture quality is exceptional. The deep blacks and vibrant colors of the OLED panel are simply breathtaking. Motion handling is smooth, thanks to the 100Hz refresh rate, making it ideal for fast-paced action movies and sports. Gaming performance is also impressive, with low input lag and excellent response times. Sound quality, while not exceptional, is sufficient for casual viewing. The SmartThings integration worked flawlessly with my other compatible devices, adding a level of convenience I truly appreciate.

I tested the AI upscaling feature with various content, including older movies and lower-resolution YouTube videos, and was consistently impressed with the results. The NQ4 AI Gen2 Processor cleverly enhances details without introducing artificial artifacts. However, I did notice a slight amount of blooming around bright objects in dark scenes, a common issue with OLED panels.

Pros:

• Stunning OLED picture quality with deep blacks and vibrant colors
• Excellent performance with the NQ4 AI Gen2 processor
• Smooth motion handling (100Hz)
• User-friendly Tizen OS with extensive app support
• Built-in SmartThings Hub for seamless smart home integration
• Great for gaming with low input lag

Cons:

• Slight blooming around bright objects in dark scenes (common in OLED)
• Sound quality is average; external speakers may be desired for optimal audio
• Price point is relatively high

The Samsung QA55S90DAUXZN is a premium OLED TV that delivers on its promises. The picture quality is outstanding, the smart features are well-integrated, and the overall performance is excellent. While the price is a significant investment, the exceptional viewing experience makes it worth considering for discerning viewers who value top-tier image quality. I highly recommend the Samsung S90D for anyone seeking an immersive and visually stunning home theater experience.
