The SAMSUNG 75-Inch Class QLED 8K QN900D Series Neo Quantum HDR Smart TV, paired with the SAMSUNG Slim Fit TV Wall Mount, offers a cutting-edge viewing experience. Here's a detailed review based on user feedback and product features.

Design and Installation: The INFINITY AIR DESIGN ensures an almost borderless screen, enhancing the viewing experience. The Slim Fit Wall Mount allows the TV to sit flush against the wall, providing a sleek, modern look. Users appreciate the minimalistic design and the ease of setup, although some noted the lack of detailed instructions.

Picture Quality: The NEO QUANTUM HDR 8K PRO technology delivers stunning picture quality with vibrant colors and deep contrasts. AI upscaling enhances lower-resolution content to near-8K quality. However, some users reported issues with the actual resolution not meeting their expectations for true 8K.

Sound Quality: While the built-in speakers are adequate for regular TV viewing, they fall short for movies and music. Most users recommend pairing the TV with a soundbar and subwoofer for an immersive audio experience.

Smart Features: The TV integrates seamlessly with SmartThings, allowing users to control connected devices like security cameras. However, there are mixed reviews about voice control compatibility, with some users unable to connect Google Assistant as advertised.

User Experience: Many users praised the convenience of the One Connect box, which reduces cable clutter and makes installation easier. However, there are complaints about compatibility issues with longer One Connect cables and difficulties in navigating the menu system.

Customer Service Issues: Several users reported significant problems with Amazon's customer service regarding damaged shipments and refund processes. These issues have led to frustration among buyers who expected better support for such a high-end product.

In conclusion, while the SAMSUNG QN900D offers exceptional picture quality and innovative design features, potential buyers should be aware of possible sound limitations and customer service challenges when purchasing through certain retailers.
