The decision between the LG NANO90 and the TCL S455 depends on what you value most in a TV and how much you are willing to spend. If you prioritize gaming performance and lower input lag for a more responsive experience, and you're willing to pay a bit more, the LG NANO90 would be the better choice. It also has a higher refresh rate, which is good for fast-moving content like sports, and performs better in brighter rooms. However, if budget is a major concern and you want a TV with deeper blacks for a better dark room viewing experience, the TCL S455 might be the right pick for you. It’s less expensive, but it doesn’t perform as well as the LG in bright rooms or for gaming. Both TVs have their strengths and shortcomings, so consider which aspects are most important for your watching habits. Give Feedback

The LG NANO90 (LCD) and TCL S455 (LCD) are both only fair for sports, though the LG NANO90 (LCD) is somewhat better.
The LG NANO90 has a decent response time and motion processing for watching sports, ensuring smoother transitions during fast-moving scenes, and reduced screen reflections, which help in bright rooms; however, its viewing angles are limited, meaning colors might fade when viewed from the side. On the other hand, the TCL S455 excels with its superb response time contributing to clear motion but has a lower motion processing capability, which could result in less smooth action during sports, and it doesn't handle reflections as well, making it less optimal for brightly lit environments, plus it also has narrower viewing angles, affecting group watching experiences.

The LG NANO90 (LCD) is very good for gaming, while the TCL S455 (LCD) is poor.
The LG NANO90 offers a good response time and very good input lag performance, suitable for gaming with fast-paced visuals and requiring quick reflexes, and it has a higher refresh rate of 120Hz. In contrast, the TCL S455, although it has the best input lag which is ideal for responsiveness in gaming, it only has a fair response time and a lower 60Hz refresh rate, which may not be as smooth for fast-moving game content.

The LG NANO90 (LCD) and TCL S455 (LCD) are both only fair for bright room, though the LG NANO90 (LCD) is somewhat better.
The LG NANO90 has good SDR and HDR brightness and handles reflections very well, which are essential for bright room viewing, but its contrast and color performance are only fair, potentially affecting picture depth and vibrancy. On the other hand, the TCL S455's SDR brightness is fair, but its HDR brightness is poor and it doesn't handle reflections as well, though it offers better contrast which helps in dark scenes but might still struggle with vibrant colors and bright scenes.

Although they have very similar scores, PerfectRec considers TCL S455 (LCD) to be only fair for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 is rated as poor for watching cartoons and animation because its colors out of the box are not optimal, and it has a fair color gamut, which affects the vibrancy and range of colors displayed. In comparison, the TCL S455 is considered fair as it also has issues with colors out of the box, yet it offers a better, albeit still not ideal, color gamut which is crucial for the vivid and varied hues typically found in cartoons and animations.

The LG NANO90 (LCD) and TCL S455 (LCD) are both only fair for news, talk, & other TV.
The LG NANO90 and TCL S455 both perform adequately in upscaling lower resolution content and have similar SDR brightness, making them suitable for news and TV programs. However, the LG NANO90's poorer colors out of the box and local dimming might not deliver as vibrant colors or deep blacks as the TCL S455, but its wider color gamut and better contrast could offer a slightly better viewing experience for such content.

"Here we have HDR pictures that look bright, but also manage to typically hit decently deep black levels.WebOS continues, though, to be one of the easiest to use. Connections are strong for a mid-range TV. Native 4K pictures look crisp and detailed."

"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 LG
LG, a prominent TV brand from Korea, has played a significant role in popularizing OLED TVs. OLED technology is hailed as the future of TV technology. Their TVs employ WebOS, a proprietary smart TV software that not only offers seamless functionality but also includes gaming-specific features, earning praise from players worldwide. Often regarded as the gateway to unparalleled viewing experiences, LG's mid-range OLEDs come highly recommended, making them a worthwhile investment for those willing to stretch their budget for superior quality.
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.
