If exceptional picture quality for movies and series is important to you, the Hisense U6H is a better choice. It offers better overall picture quality, contrast, and performance in dark rooms, which are great for cinematic experiences. However, if you're sensitive to price, the TCL S455 is generally less expensive and still offers good quality for the price, with decent scores across the board for a variety of content, including news and animation. For gaming, the Hisense U6H also performs better, but if you play casually, the TCL S455 might be sufficient and more cost-effective. In bright rooms, both TVs perform reasonably well, but the Hisense U6H has a slight edge. Both have similar input lag performance, making either a good option for watching live content or using as a monitor. Sound quality is similar between the two, so if you plan on using the TV speakers, either option should be fine. However, consider a separate sound system for the best audio experience. Keep in mind, the Hisense offers better HDR format support which can enhance the viewing experience for compatible content. Give Feedback

The Hisense U6H (LCD) is good for movies & TV, while the TCL S455 (LCD) is only fair.
The Hisense U6H is better for movies and cinematic TV because it has higher contrast, superior local dimming, and better black uniformity which are pivotal for dark scene performance and depth in visuals. On the other hand, the TCL S455 falls short in local dimming and black uniformity, which affects the richness of dark scenes and overall picture quality, although it demonstrates superior gray uniformity, which may be beneficial for sports or general TV viewing in brightly lit rooms.

The Hisense U6H (LCD) is only fair for gaming, while the TCL S455 (LCD) is poor.
The Hisense U6H has better input lag performance which is favorable for gaming, allowing for quicker reaction times in games, while the TCL S455, despite its good input lag, has a poorer response time that could result in motion blur during fast-paced scenes. Both TVs have a refresh rate of 60Hz, which is adequate for most gaming, but not optimal for high frame rate gaming that requires faster refresh rates.

The Hisense U6H (LCD) is very good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The Hisense U6H performs better for watching cartoons and animation than the TCL S455 because it offers excellent colors straight out of the box along with a good color gamut and volume, which are essential for vibrant and consistent on-screen animation. On the other hand, the TCL S455 delivers only fair performance in these areas, with a fair out-of-the-box color reproduction and poor color gamut, resulting in less impressive visual presentation for animated content.

The Hisense U6H (LCD) is good for bright room, while the TCL S455 (LCD) is only fair.
The Hisense U6H delivers better performance in bright rooms due to its higher SDR and HDR brightness, which means it can produce brighter images that stand out more in well-lit environments. Both the Hisense U6H and the TCL S455 handle reflections similarly, which is fairly well, but the TCL S455 suffers in a bright room due to lower brightness and inferior contrast when compared to Hisense U6H, making the image appear more washed out.

The TCL S455 (LCD) and Hisense U6H (LCD) are both only fair for sports.
The Hisense U6H and TCL S455 both have limitations when watching sports, primarily due to their fair response times which can lead to motion blur, and their merely fair handling of reflections that can cause distractions in well-lit environments. Additionally, the viewing angles are not wide on either model, meaning the picture quality could diminish when viewed from the side; however, the Hisense U6H performs slightly better in this regard.

Tom's guide
Matthew Murray | March 2023
"A budget TV that exceeds expectations. (...) For a TV that costs as little as this one does, its brightness and color are above-average (...) The U6H may not get quite as bright as its splashier siblings, but for its class, it fares pretty well. (...) As far as input lag, the U6H is an impressive performer. (...) Costing less than most of its direct competitors, and matching or bettering them in several key areas, it’s an irresistible value proposition. (...)"

"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 Hisense
Hisense, a Chinese TV manufacturer, entered the US market in approximately 2011 and has since acquired TV divisions from various companies such as Toshiba, Sharp, Hitachi, and NEC. Currently ranking as the fourth largest vendor in terms of sales volume, Hisense aims to capture a wide range of TV budget segments. They offer exceptional value with TVs that often outperform their competitors at similar price points, making them a compelling choice for consumers. In the US, they use Google TV as their smart TV software which provides the largest app selection and a very modern user interface, however it is not as user friendly as the software from other vendors.
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.
