The LG NANO90 is a midrange-priced TV which is generally more expensive than the TCL S450G, which has a budget price. When it comes to overall picture quality, gaming, and sports viewing, the LG NANO90 performs better, making it a more suitable choice if you prioritize these aspects and are willing to pay more. It also has a higher number of HDMI ports and superior sound quality, but neither set has great built-in speakers. For darker rooms, the TCL S450G might not be as good as the LG NANO90, but it's a more suitable budget-friendly option if you want a solid TV without the added cost. However, its lower number of HDMI ports and lesser sound quality should be considered if you plan to connect multiple devices or want better audio without an external sound system. The TCL model also offers voice command features, which the LG doesn't. In bright rooms, neither TV is exceptional, but the LG NANO90 has a slight edge. For viewers with wide seating, the LG has a better viewing angle. Gamers preferring high responsiveness will find the TCL S450G has a marginally better input lag performance, although the LG NANO90 has a higher refresh rate which is beneficial for fast-paced content. Neither model supports advanced HDR formats like HDR10+ or Dolby Vision, which could be a deciding factor if you consume a lot of HDR content. Give Feedback

"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."

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.
