When considering the Sony A90K and Samsung QN90A, prioritize what's important for your viewing experience. The Sony A90K, being an OLED TV, offers deeper blacks and wider viewing angles, making it excellent for movies and HDR content. It's also top-notch for gaming, although less suited for very bright rooms. On the other hand, the Samsung QN90A, with its LCD screen and higher brightness, excels in bright environments and can handle reflections better, which is great for daytime sports viewing or news watching. The Samsung also includes built-in great speakers. If budget is a concern, the Samsung provides a cost-effective alternative without a significant compromise on quality. Give Feedback
