The TCL Q6 offers slightly better overall picture quality and performs better in bright rooms compared to the TCL S455. If you're willing to pay a bit more for improved bright room viewing, consider the TCL Q6. Otherwise, if budget is a priority, the TCL S455 is a solid choice. Both TVs may not be the best option for darker environments due to lower performance in dark rooms. Give Feedback

The TCL Q6 (LCD) and TCL S455 (LCD) are both only fair for cartoons & animation, though the TCL Q6 (LCD) is somewhat better.
The TCL Q6 has poor colors out of the box, but a good color gamut, meaning it can display a wide range of colors initially, but those colors might not be accurately represented. On the other hand, the TCL S455 also has fair performance in colors right out of the box and a poor color gamut, indicating a more limited color range that might affect the vibrancy of cartoons and animations.

The TCL Q6 (LCD) is good for bright room, while the TCL S455 (LCD) is only fair.
The TCL Q6 is better suited for bright rooms because it has very good SDR brightness and good HDR brightness, allowing it to maintain picture quality even in well-lit environments, although reflection handling is not its strong suit. In comparison, the TCL S455 has fair SDR brightness and poor HDR brightness, which means it may struggle more with visibility in bright conditions, but it handles reflections slightly better than the TCL Q6.

Although they have very similar scores, PerfectRec considers TCL S455 (LCD) to be only fair for movies & TV, while the TCL Q6 (LCD) is poor.
The TCL Q6 falls short in watching movies and cinematic TV due to its poor local dimming and black uniformity, both crucial for displaying deep blacks essential for a good contrast ratio. The TCL S455 demonstrates somewhat better performance due to its higher contrast and somewhat better color reproduction, but its poor local dimming still limits its ability to deliver truly cinematic quality.

The TCL Q6 (LCD) and TCL S455 (LCD) are both only fair for sports.
The TCL Q6 and S455 both have fair response times, which is crucial for sports, but they may not handle fast-moving scenes as well as TVs with better motion processing. They both struggle with reflections handling and have limited viewing angles, meaning they might not be the best choice for wide seating arrangements or bright rooms.

The TCL Q6 (LCD) and TCL S455 (LCD) are both poor for gaming.
Both the TCL Q6 and TCL S455 have response time and input lag metrics that are not suited for high-end gaming. While they excel in providing a quick response to input signals, essential for competitive gaming, their slower response times can lead to motion blur and reduce the clarity of fast-moving images which is detrimental to gaming performance.

The TCL S455 (LCD) and TCL Q6 (LCD) are both only fair for news, talk, & other TV.
The TCL Q6 and TCL S455 both perform adequately for watching news and talk shows due partly to their upscaling capabilities which is significant considering the content might not always be high-resolution. However, the TCL S455 has better upscaling and fair color accuracy out of the box which is beneficial for such programs, while the TCL Q6 offers very good SDR brightness for better visibility in brighter rooms but with a slightly less accurate color presentation straight out of the box.

"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 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.
