The Sony X77L is more expensive, offering relatively better gaming experience and performance in bright rooms compared to the TCL S455, which is priced more budget-friendly. However, the TCL S455 has superior contrast and black uniformity, making it a better option for dark room viewing. If budget is a concern and you primarily watch in the dark, the TCL S455 is a sensible choice. On the other hand, if you are willing to invest more for gaming and use in brighter environments, the Sony X77L would be more appropriate. Both TVs offer similar support for HDR formats and connectivity options. Give Feedback

The TCL S455 (LCD) is only fair for movies & TV, while the Sony X77L (LCD) is poor.
The Sony X77L has weaker contrast and black uniformity compared to the TCL S455, making it less ideal for movies and cinematic TV that often have darker scenes, and its fair colors out of the box may not deliver the most accurate cinematic color experiences. Conversely, the TCL S455, while having excellent black uniformity which enhances movie and cinematic TV viewing in dark scenes, suffers from poor viewing angles, meaning the color and contrast could be compromised when viewed from off-center positions.

The Sony X77L (LCD) and TCL S455 (LCD) are both only fair for sports, though the Sony X77L (LCD) is somewhat better.
The Sony X77L has wider viewing angles and better upscaling which make it more suitable for watching sports with a group and for presenting more consistent quality across various content sources, but weak motion processing may result in blur during fast action. The TCL S455, on the other hand, handles reflections similarly to the Sony but has slower response time which could lead to more motion blur; it compensates with excellent black uniformity, lending to better performance in dark scenes.

The Sony X77L (LCD) and TCL S455 (LCD) are both poor for gaming.
The Sony X77L has a poor response time, which can lead to motion blur during fast-paced games, and while it has very good input lag for a responsive gaming feel, its standard refresh rate may not satisfy competitive gamers. On the other hand, the TCL S455 also has fair response time that may affect the smoothness of fast-moving images, and while it features the best input lag making it very responsive, it, too, has the standard refresh rate which is not ideal for high-frame-rate gaming.

The TCL S455 (LCD) and Sony X77L (LCD) are both only fair for cartoons & animation.
The Sony X77L is better for watching cartoons and animation as it provides very good colors out of the box, which means it displays accurate colors without the need for much adjustment, but it has a poor color gamut, limiting the range of colors it can show. On the other hand, the TCL S455 is fair in delivering colors right out of the box and also has a poor color gamut, suggesting both TVs may not be the best at displaying the wide range of colors typically found in animated content.

The TCL S455 (LCD) and Sony X77L (LCD) are both only fair for news, talk, & other TV.
The Sony X77L and the TCL S455 both perform fairly in upscaling and SDR brightness, which is very important for watching news and TV shows, providing adequate picture clarity from lower resolution sources and sufficient brightness in regular lighting conditions. However, the Sony X77L has an advantage with somewhat better color accuracy out of the box, which means it can display more true-to-life colors without the need for calibration, and this could enhance the viewing experience for color-rich content even if its contrast is lower compared to the TCL S455, which may make it a slightly better option for varied viewing environments.

The Sony X77L (LCD) and TCL S455 (LCD) are both only fair for bright room.
The Sony X77L and TCL S455 are both fair for watching TV in bright rooms primarily because their SDR and HDR brightness are not outstanding; they provide sufficient but not high levels of brightness to combat glare. Additionally, their capability to handle reflections is only fair, so they will not eliminate all reflections caused by light sources, which is crucial for maintaining picture quality in well-lit environments.

"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
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.
