The Samsung QN90A is a solid choice for a vibrant room due to its superior bright room performance and better handling of reflections; it'll display a more vivid picture when the lights are on. It also has better quality control and quality assurance scores, indicating a potentially more reliable product. Additionally, its overall picture quality, motion processing, and upscaling are superior, making it an excellent TV for mixed content, including movies, sports, and gaming. On the other hand, the TCL R648, while generally more expensive, offers an 8k resolution which can provide sharper images for compatible content. However, keep in mind that 8k content is still rare, and this TV has lower scores for sports content, dark room viewing, and local dimming than the Samsung, meaning that it may not perform as well in those areas. The R648 also has a lower bright room score, so it might not be as clear in well-lit conditions. If gaming is a priority, both TVs perform well, but the Samsung has a slight edge. Ultimately, if you're looking for an all-around performer with excellence in varied lighting conditions and a high likelihood of great build quality, the Samsung QN90A could be a better fit. If you are focused on future-proofing for 8k content and can compromise on some other visual aspects, the TCL R648 could be your choice. Give Feedback

The Samsung QN90A (LCD) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The Samsung QN90A is very good for watching news, talk shows, and other TV programs because of its excellent upscaling and SDR brightness, ensuring a bright and clear picture, along with strong local dimming and a wide color gamut that provide rich contrast and vibrant colors. The TCL R648 is good in the same scenario, also offering excellent upscaling and SDR brightness, but it has a slightly lower performance in local dimming and colors out of the box, which may affect the depth of the viewable picture contrast and color realism to a minor extent.

Although they have very similar scores, PerfectRec considers Samsung QN90A (LCD) to be good for sports, while the TCL R648 (LCD) is only fair.
The Samsung QN90A excels in sports watching due to its faster response time and superior motion processing, which ensures smooth action without blur, and it handles reflections better, making it suitable for bright rooms. Conversely, the TCL R648, while also good, may not handle fast-moving sports scenes as well, and its narrower viewing angles could limit the view for those sitting off to the side.

About Samsung
Samsung, a South Korean electronics manufacturer, holds the title of being the largest global TV vendor in terms of units sold. They offer a diverse lineup of TV products that cater to various budget ranges. A notable achievement in recent years is the development of Quantum Dots, a technology that enhances color reproduction, resulting in richer and more vibrant hues. Samsung TVs are well-regarded for their high manufacturing quality and user-friendly software, making them an excellent choice for consumers seeking an intuitive viewing experience.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
