If you are looking for a TV with a better overall picture quality, especially for movies and gaming, the TCL S555 would be a great choice. It performs better in both dark and bright rooms compared to the LG NANO75. However, if you're a sports enthusiast, the LG NANO75 might be slightly more appealing as it has a higher sports content viewing experience. Additionally, the LG TV is often significantly more expensive than the TCL. Both TVs have similar sound quality, support HDR, and have a low input lag which is good for gaming. Neither TV supports Dolby Vision or HDR10+. Keep in mind that the TCL offers better contrast and local dimming features, which can enhance the viewing experience for movies and general TV-watching.

The TCL S555 (LCD) has good picture quality, while the LG NANO75 (LCD) has poor picture quality.
The LG NANO75 struggles with picture quality due to poor contrast, lackluster HDR brightness, and subpar black uniformity, which lead to washed out images and dull colors especially in dark scenes. In contrast, the TCL S555 offers better picture quality with its excellent contrast, effective local dimming, and wider color gamut, resulting in more vibrant and true-to-life images.

The TCL S555 (LCD) is only fair for gaming, while the LG NANO75 (LCD) is poor.
The LG NANO75 has fair response time but is paired with the best input lag performance, while the TCL S555 also has good response time but matches the LG NANO75 in having the best input lag performance. This implies that while both TVs are capable of gaming, the LG's overall poorer response time compared to the TCL makes it less suited for fast-paced gaming where quick screen updates are crucial.

The TCL S555 (LCD) is very good for cartoons & animation, while the LG NANO75 (LCD) is poor.
The LG NANO75 displays colors out of the box adequately but has a limited color gamut, making it less ideal for vibrant and varied animation scenes. In contrast, the TCL S555 excels with very good color reproduction straight out of the box and a superior color gamut, offering a richer and more diverse palette that enhances the animation viewing experience.

The TCL S555 (LCD) is good for news, talk, & other TV, while the LG NANO75 (LCD) is only fair.
The TCL S555 boasts superior contrast and SDR brightness, making it well-suited for viewing in various lighting conditions and offering vivid pictures for news and talk shows. Conversely, the LG NANO75, while capable of good upscaling for lower resolution content, falls short in SDR brightness and contrast, affecting its ability to deliver as vibrant and clear images as the TCL S555 in standard dynamic range viewing scenarios.

The TCL S555 (LCD) is good for bright room, while the LG NANO75 (LCD) is poor.
The LG NANO75 struggles in bright rooms because it has poor SDR and HDR brightness and only good reflection handling, making it less ideal for well-lit environments. In contrast, the TCL S555 performs better due to its very good SDR brightness and good HDR brightness coupled with poor reflection handling, which still allows it to handle bright rooms better than the LG NANO75 despite reflected light.

The LG NANO75 (LCD) and TCL S555 (LCD) are both only fair for sports.
Both the LG NANO75 and the TCL S555 have their advantages and disadvantages when it comes to watching sports. The LG NANO75 offers better viewing angles, making it a good fit for a wide-seating arrangement, but its motion processing and response time are only adequate, which may lead to some motion blur during fast-paced games; additionally, its reflection handling is good, which is beneficial in well-lit rooms.

"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.
