The LG NANO90 is typically much more expensive than the TCL S555 and offers better performance for gaming with faster response times and lower input lag, which is important if you play video games. It has a higher peak brightness which is beneficial for bright room viewing, but it may not perform as well in dark rooms due to its lower contrast and black uniformity. On the other hand, the TCL S555, while less expensive, performs better for watching movies and series, with higher contrast, making it more suitable for dark room viewing. However, it's not as well-suited for gaming compared to the NANO90 and may not handle reflections as well, which can be a drawback in bright rooms. Both TVs support Dolby Vision and HDR10, but the LG NANO90 has a higher refresh rate, which can benefit fast-moving content such as sports. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the LG NANO90 (LCD) is poor.
The TCL S555 outperforms the LG NANO90 in movie and cinematic TV watching primarily because it has a much better contrast ratio and superior black uniformity, resulting in deeper blacks and more defined shadow details which are crucial for dark scenes. While the LG NANO90 offers a wider viewing angle, its performance in key movie-watching aspects is hampered by poorer contrast, local dimming, and black uniformity and despite having good color accuracy out of the box, it doesn't match the TCL S555's performance in these very important factors.

The LG NANO90 (LCD) is very good for gaming, while the TCL S555 (LCD) is only fair.
The LG NANO90 offers a superior gaming experience due to its very good response time and input lag which are crucial for fast-paced games, whereas the TCL S555, while still providing a good response time, has a lower input lag performance impacting its gaming capabilities. Additionally, the LG model has a higher refresh rate that delivers smoother motion, making it more suitable for gaming compared to the TCL S555 with its standard refresh rate.

The TCL S555 (LCD) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 displays colors fairly well out of the box and has a fair color gamut, making it less suitable for the vibrant and varied colors typically found in cartoons and animation. Contrarily, the TCL S555 excels in these areas with very good performance for colors right out of the box and the best color gamut, enhancing the viewing experience for such content.

The TCL S555 (LCD) is good for news, talk, & other TV, while the LG NANO90 (LCD) is only fair.
The TCL S555 is noted for better performance in upscaling and colors out of the box, which means this TV can enhance lower resolution content from news or talk shows more effectively and deliver more accurate colors without adjustments. In contrast, while the LG NANO90 offers good SDR brightness for well-lit rooms, its relatively poorer upscaling and initial color accuracy may require extra tweaking for an optimal news and talk show watching experience.

The LG NANO90 (LCD) and TCL S555 (LCD) are both only fair for sports.
The LG NANO90 is fair for watching sports due to its good response time and handling of reflections, and it also has a wider viewing angle suitable for larger groups. Conversely, the TCL S555, while also fair for sports, may struggle more with reflections in bright rooms and has a narrower viewing angle, but it has slightly better gray uniformity, which can be important for field sports with large, uniform color areas.

"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."

"It looks great out of the box and the picture quality it is rock-solid for the price. (...) What really makes this a decent gaming TV, though, is the very low input lag. (...) But if you want to save a little money, the TCL S555 strikes a great balance between cost and performance – the kind of performance that’s impressive enough to deliver some wow to your eyes. (...)"

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.
