The Samsung Q80B is a higher-priced option that excels in gaming due to its low input lag and quick response time. Its performance in bright rooms is good, making it suitable for well-lit spaces. However, its dark room performance is average, which might detract from watching movies in low light. The TCL R646, though less expensive, offers better overall picture quality, superior dark room and bright room performance, and great black uniformity, which is important for enjoying movies. It may not be as responsive as the Samsung for gaming, and its sound quality is lower. The best choice depends on your priorities: if gaming and bright room performance are key, consider the Samsung Q80B; for better movie-watching in various lighting conditions at a lower price, the TCL R646 is a strong contender.

The TCL R646 (LCD) is good for movies & TV, while the Samsung Q80B (LCD) is only fair.
The TCL R646 provides a superior movie-watching experience compared to the Samsung Q80B, primarily due to its higher contrast ratio, more effective local dimming, and better black uniformity, which are crucial for deep dark scenes typical in movies. However, the Samsung Q80B offers better viewing angles and color accuracy straight out of the box, which could be beneficial when watching content with a group or if immediate viewing without calibration is preferred.

The TCL R646 (LCD) is very good for cartoons & animation, while the Samsung Q80B (LCD) is good.
The Samsung Q80B and TCL R646 are both commended for watching cartoons and animation because they offer pleasing colors right out of the box and have a similar color gamut, which ensures a wide range of colors. However, while both are assessed as having 'good' performance on these aspects, the TCL R646 pulls ahead slightly due to its superior contrast, which can make images pop more, a factor that is somewhat important for this type of content.

The TCL R646 (LCD) is very good for bright room, while the Samsung Q80B (LCD) is good.
The TCL R646 outperforms the Samsung Q80B in a bright room primarily because it has excellent SDR and very good HDR brightness, combined with very good handling of reflections, which helps maintain picture quality even in well-lit environments. In contrast, while the Samsung Q80B has very good SDR brightness and fair reflection handling, these factors make it slightly less optimal than the TCL R646 for viewing in bright rooms.

The Samsung Q80B (LCD) and TCL R646 (LCD) are both only fair for sports.
The Samsung Q80B and TCL R646 both have a good response time which is crucial for sports, but the Samsung Q80B has a lower reflection handling capability which can be a drawback in well-lit rooms. Although the Samsung has wider viewing angles which is beneficial for viewing with a group, the TCL R646 handles reflections better, making it preferential in brighter environments; both have similar motion processing capabilities, but neither excels at gray uniformity which is somewhat important for sports viewing..

Tom's guide
Matthew Murray | February 2023
"For most people its picture, sound, and price make it a midrange TV worth considering. HDR brightness was generally exceptional. Its viewing angles are shockingly good, among the very best we’ve seen recently from any non-OLED TV. For gamers input lag isn’t too shabby."

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.
