If you watch a lot of movies and want higher quality pictures in a dark room, the LG QNED90 with better dark room performance could be appealing, but it comes at an upper midrange price. Conversely, if you're on a budget and enjoy cartoons and animation, the TCL S555, which excels in these areas, is much more affordable. The LG has better gaming performance and sound quality, ideal if gaming is a priority. However, for general TV watching in bright rooms, both TVs perform similarly. The TCL has a striking contrast, which benefits movie watching, albeit with a lower sound quality than the LG. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the LG QNED90 (LCD) is only fair.
The TCL S555 outperforms the LG QNED90 in crucial aspects like contrast and black uniformity, which are vital for deep blacks and rich picture quality in movies and cinematic TV. Moreover, while the LG has slightly better colors out of the box, the color performance of the TCL is also very good, but the LG has a wider viewing angle, which might be preferable if you often watch TV with a group spread out across the room.

The LG QNED90 (LCD) is very good for gaming, while the TCL S555 (LCD) is only fair.
The LG QNED90 has a faster response time and lower input lag, making it very good for gaming as it allows for smoother motion and better synchronization between user input and on-screen action. In contrast, the TCL S555, despite offering the best input lag, has a slower response time, which may lead to less fluid motion, affecting its gaming performance and making it only fair for gaming.

The TCL S555 (LCD) is very good for cartoons & animation, while the LG QNED90 (LCD) is good.
The LG QNED90 is good for watching cartoons and animation due to its good color performance right out of the box and a good color gamut, which ensures a wide range of colors. Although the TCL S555 has a very good out-of-the-box color accuracy which makes animations pop without much adjustment, it still has an overall color gamut that is good, similar to the LG, making it also a suitable choice for vibrant animation content.

The LG QNED90 (LCD) and TCL S555 (LCD) are both only fair for sports.
The LG QNED90 provides a wider viewing angle and better motion processing which is important while watching sports, though it struggles with reflections, more so than the TCL S555 which has a lower response time. Both the LG QNED90 and TCL S555 handle gray uniformity well, which is somewhat important, but the TCL has superior reflection handling, making it preferable in bright rooms, although it doesn't process motion as effectively as LG's model.

The LG QNED90 (LCD) and TCL S555 (LCD) are both good for bright room.
The LG QNED90 performs well in bright rooms because it has very good SDR and HDR brightness and handles reflections adequately, although not as strongly as its SDR and HDR brightness would suggest. The TCL S555, with its very good SDR brightness and good HDR brightness, also performs well in bright rooms but has poorer reflection handling, which could be more noticeable in well-lit environments.

"When it comes to HDR brightness it has very bright highlights and impressive HDR. In terms of design the QNED90 looks beautiful. The TV did great with fast response times, excellent reactions and instant rendering of all our commands. If you look for a good performing premium 4K TV the QNED90 ticks all the boxes."

"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.
