The Samsung QN90B is a premium-priced option that generally costs much more than the TCL Q7. It stands out for having excellent picture quality and sound, making it a strong candidate for watching movies and playing video games. It also performs very well in bright rooms due to its high brightness and reflection handling. Conversely, the TCL Q7 is priced lower and could be a more budget-friendly option. While it performs decently overall, it might not match the Samsung's performance, particularly in bright rooms and with off-angle viewing. It still offers a good experience for gaming and has great sound clarity. If budget is a major consideration and you primarily watch content in a relatively dark or controlled lighting environment, the TCL Q7 could be a satisfactory choice. If you prioritize a superior viewing experience, especially in well-lit spaces, and can afford the higher price, the Samsung QN90B would likely be preferable. Give Feedback

The Samsung QN90B (LCD) is good for sports, while the TCL Q7 (LCD) is only fair.
The Samsung QN90B is better suited for sports viewing because it has a faster response time and more effective motion processing which keeps the action smooth, while its excellent reflection handling and wider viewing angles maintain image clarity from different seating positions. On the other hand, the TCL Q7, despite its strong points, falls short in these key areas with slower motion processing, poorer reflection handling, and narrower viewing angles which can be detrimental to following fast-paced sports.

The Samsung QN90B (LCD) is very good for cartoons & animation, while the TCL Q7 (LCD) is good.
The Samsung QN90B excels in displaying cartoons and animation due to its top-tier colors straight out of the box and good color gamut, which enhances the vibrancy and accuracy of animated content. In contrast, the TCL Q7 is capable but slightly less impressive in the same category; while it also offers good color gamut, its colors out of the box are not as superior as the Samsung's, making the QN90B better suited for animation enthusiasts who prioritize color performance.

The Samsung QN90B excels in upscaling and SDR brightness, which are crucial for watching news and talk shows, ensuring clarity and visibility even in bright conditions. The TCL Q7 is less adept in these areas and thus offers a fair experience that may not be as sharp or as easily viewable in various lighting conditions.

Although they have very similar scores, PerfectRec considers Samsung QN90B (LCD) to be very good for movies & TV, while the TCL Q7 (LCD) is good.
The Samsung QN90B delivers a very good experience for movies and cinematic TV, largely due to its excellent local dimming and black uniformity, which bolster contrast and create deeper blacks, enhancing dark scenes. The TCL Q7, despite its superior contrast, scores lower in local dimming and viewing angles, but still offers a good experience with its remarkable black uniformity, which is crucial for maintaining picture quality in dark sections of movies.

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."

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.
