The Samsung QN90A is a high-end model that excels in bright room performance, offering a stellar picture with great gaming capabilities and a wide range of features. You'll enjoy vibrant colors and deep contrasts, and it comes with enhancements like Dolby Atmos support, but it comes at a premium price. On the other hand, the Samsung CU8000 is a more budget-friendly option that still provides a decent viewing experience, particularly for sports and animation. While it may not have the same advanced features or picture quality as the QN90A, it's a good choice for those looking for a more affordable television. Give Feedback

The Samsung QN90A (LCD) is good for sports, while the Samsung CU8000 (LCD) is only fair.
The Samsung QN90A excels in watching sports due to its exceptional response time and ability to handle reflections, which makes it a great fit for high-motion content in bright rooms. In comparison, the Samsung CU8000 has a lower response time and poorer reflection handling, which can affect the clarity of fast-moving sports scenes and visibility in well-lit environments.

The Samsung QN90A (LCD) is very good for gaming, while the Samsung CU8000 (LCD) is poor.
The Samsung QN90A is superior in gaming because it has excellent response time and input lag, making fast-moving images clearer and gameplay more responsive.

The Samsung QN90A (LCD) is very good for news, talk, & other TV, while the Samsung CU8000 (LCD) is poor.
The Samsung QN90A excels in watching news and typical TV programs because it has excellent upscaling to make lower resolution content look clearer and good SDR brightness for vibrant display in any room lighting. In contrast, the Samsung CU8000 falls short in these areas, offering poorer upscaling, resulting in less clarity for lower resolution content, and has fair SDR brightness, which may not be as vivid, especially in well-lit rooms.
