If you're looking for a more affordable option, the LG UQ7570 might be suitable for you, although it has poor performance across most categories, including picture quality, gaming, and viewing in both dark and bright rooms, which could significantly impact your viewing experience. On the other hand, the Samsung QN90C, while typically much more expensive, delivers very good picture quality, gaming performance, and is excellent for bright room viewing. If you're an avid gamer, enjoy watching movies, or have a brightly lit room, the Samsung QN90C is likely to provide a much more satisfying experience. It also has additional features such as better sound quality, a higher refresh rate, and more HDMI ports, which could be important if you plan to connect multiple devices. Give Feedback
