The Samsung QN90C offers a premium viewing experience with excellent performance in bright rooms and superior motion processing, making it a good fit for mixed usage, such as watching sports or playing games. It also comes with better sound quality and some additional smart features like voice commands. On the other hand, the TCL R646 is more budget-friendly and still performs well overall, particularly in dark rooms. However, it has a narrower viewing angle and is not as well-suited for bright rooms or fast-moving content due to its lower motion processing capabilities. If you prioritize a high-quality picture and advanced features and are willing to pay more, the Samsung QN90C would be the better choice. If you're looking for a good overall TV and want to save money, the TCL R646 could be a great option. Give Feedback

The Samsung QN90C (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The Samsung QN90C is very good for watching news, talk shows, and other TV programs because it has excellent upscaling for lower resolution content and colors that look great right out of the box. In comparison, the TCL R646 is good for such content, having lesser upscaling quality but still providing solid colors out of the box, making it a cost-effective option for day-to-day viewing programs.

On the other hand, the TCL R646 is also very good for bright room viewing with its high brightness and good reflection handling but falls short of the Samsung's peak brightness and anti-reflective capabilities.

Although they have very similar scores, PerfectRec considers Samsung QN90C (LCD) to be very good for movies & TV, while the TCL R646 (LCD) is good.
The Samsung QN90C provides exceptional movie and cinematic TV watching experiences mainly due to its outstanding contrast, effective local dimming, and excellent black uniformity, which are vital for dark scene reproduction. The TCL R646, while still good, has lower contrast, less effective local dimming, and very good black uniformity, translating to a less optimal but still pleasing performance in those same areas.

Although they have very similar scores, PerfectRec considers Samsung QN90C (LCD) to be good for sports, while the TCL R646 (LCD) is only fair.
The Samsung QN90C is better for watching sports due to its superior viewing angles and reflection handling, which maintains a clear image from different positions and in bright rooms. The TCL R646 falls short with more limited viewing angles and less effective motion processing, meaning it may not keep fast-moving scenes as smooth.

The Samsung QN90C (LCD) and TCL R646 (LCD) are both very good for gaming.
The Samsung QN90C stands out for gaming due to its excellent response time and input lag, making it highly responsive, suitable for fast-paced gaming. In contrast, the TCL R646, while offering very good input lag, doesn't match the response time of the Samsung, which could affect its performance in very fast games.

The Samsung QN90C (LCD) and TCL R646 (LCD) are both very good for cartoons & animation.
The Samsung QN90C and TCL R646 deliver vibrant and extensive color displays essential for watching cartoons and animation, with the Samsung being particularly strong 'out of the box', which means less tweaking is needed for optimal color settings, and both have a respectable color gamut ensuring a wide spectrum of colors. However, the Samsung edges out with a better color volume, giving it an advantage in maintaining color richness at varying levels of brightness, which is somewhat important for retaining visual impact across different scenes.

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.
