The TCL S446 is a budget-friendly option and performs well for cartoons and animation but struggles in a dark room due to lower black uniformity. If you're looking for a less expensive TV and mostly watch animated content or news, this could be suitable for you. The Vizio Quantum Pro, on the other hand, is priced in the upper midrange and offers a better overall picture quality and sound quality, with higher scores in bright rooms and for gaming. It also supports more HDR formats, which enhances movie and gaming experiences. If you're willing to spend more for a better experience in varied viewing situations, especially if you enjoy gaming or watching content in bright rooms, then the Vizio Quantum Pro would be the better choice. It's more capable for a dark room as well but doesn't excel in this environment. Give Feedback

The Vizio Quantum Pro (LCD) is only fair for movies & TV, while the TCL S446 (LCD) is poor.
The TCL S446 struggles with movies and cinematic TV due to its poor black uniformity and lack of local dimming, which affects its contrast performance, making dark scenes look washed out. In comparison, the Vizio Quantum Pro delivers better contrast and a fair representation of colors, partly because of its local dimming capability and slightly better black uniformity, which are important for a cinematic experience.

The Vizio Quantum Pro (LCD) is very good for gaming, while the TCL S446 (LCD) is poor.
The TCL S446's fair response time and very good input lag mean it's not as quick or responsive for gaming compared to the Vizio Quantum Pro, which features very good ratings for both response time and input lag. Additionally, the Vizio has a higher refresh rate of 120Hz, enhancing the gaming experience with smoother motion, while the TCL has a lower 60Hz refresh rate, which is less optimal for fast-paced gaming action.

The Vizio Quantum Pro (LCD) is good for cartoons & animation, while the TCL S446 (LCD) is only fair.
The TCL S446 is considered fair for watching cartoons and animation because it performs well with colors out of the box, meaning it can display vibrant and accurate colors without much adjustment, but it has a poor color gamut which limits its ability to display a wide range of colors. In contrast, the Vizio Quantum Pro is considered good in this regard due to its very good color gamut that offers a wider range of colors and very good color volume, which enhances the ability to display different shades of colors across different brightness levels, even though its colors out of the box are only fair and may require some adjustment for optimal viewing.

The Vizio Quantum Pro (LCD) is good for bright room, while the TCL S446 (LCD) is poor.
The TCL S446 has fair SDR and poor HDR brightness, along with good ability to handle reflections, but its lower brightness levels and lack of local dimming make it less suitable for a bright room compared to the Vizio Quantum Pro, which offers very good SDR and good HDR brightness, coupled with very good reflection handling, making it a better option for bright environments. Additionally, the Vizio's higher scores in color volume and color gamut result in richer and more varied colors, enhancing the viewing experience in well-lit conditions.

The Vizio Quantum Pro (LCD) and TCL S446 (LCD) are both only fair for sports.
The TCL S446 has slower motion processing which could result in more blur during fast sports scenes and it doesn't handle reflections as well, making it less ideal for bright rooms, while the Vizio Quantum Pro has better motion processing due to its higher refresh rate which can be beneficial for action-packed sports, but both TVs offer limited viewing angles which means the picture quality can degrade when viewed from the side. Even though both TVs have fair gray uniformity that might affect viewing when displaying sports fields or courts with uniform colors, the TCL S446 has a lower response time, making it less suitable for fast-moving sports compared to the Vizio Quantum Pro.

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.
About Vizio
Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
