If you're looking for premium picture quality and gaming performance, the Samsung QN90A is the better choice, especially in bright rooms due to its higher brightness capabilities. However, it comes with a higher price tag. On the other hand, the TCL S450G offers a budget-friendly option with decent overall performance for various content types, but it's not as suitable for dark rooms or competitive gaming due to its lesser dark room performance and gaming features. Additionally, the TCL's lower brightness might not be ideal if you have a very sunny room. Give Feedback

The Samsung QN90A (LCD) is very good for movies & TV, while the TCL S450G (LCD) is poor.
The Samsung QN90A delivers a very good movie and cinematic TV experience with high contrast, effective local dimming, and robust black uniformity, ensuring deep blacks and minimal blooming around bright objects, which is crucial for dark scene details. Conversely, the TCL S450G is rated as poor because it falls short in these areas with lower contrast, weaker local dimming, and less consistent black uniformity, leading to a less immersive experience, particularly in darker content.

The Samsung QN90A (LCD) is good for sports, while the TCL S450G (LCD) is only fair.
The Samsung QN90A excels in fast response time and handles reflections very well, making it better for watching sports, while the TCL S450G has a poorer response time and only fair performance with reflections, affecting its ability to display fast-paced sports content clearly, especially in bright rooms. Both TVs have comparable gray uniformity, which is somewhat important for sports watching, but the superior motion processing and viewing angles of the Samsung QN90A give it an advantage for a more immersive viewing experience.

The Samsung QN90A (LCD) is very good for gaming, while the TCL S450G (LCD) is poor.
The Samsung QN90A delivers a superior gaming experience because it has a higher refresh rate and ranks very good for both response time and input lag, making it responsive and smooth during game play. In contrast, the TCL S450G, while having the best input lag which is favorable, falls behind due to its lower refresh rate and poor response time, leading to a less fluid and potentially more delayed gaming experience.

The Samsung QN90A (LCD) is very good for cartoons & animation, while the TCL S450G (LCD) is poor.
The Samsung QN90A displays cartoons and animation better partly because it has best-in-class colors right out of the box and a better color gamut, which means it can reproduce a wider and more accurate range of colors compared to the TCL S450G, which has lower scores in these areas.

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.
