If gaming performance and motion processing are important for you, the LG NANO90 is a better choice with its higher gaming and motion scores; its HDMI ports also support higher refresh rates which is great for gaming. However, if budget is a key consideration and you're looking for a TV with excellent black uniformity for watching movies in dark rooms, the TCL S450F could be more appealing. Keep in mind that while the TCL S450F may save you money, it's not as well-suited for brightly lit rooms or diverse gaming needs. Both TVs support HDR, but only the LG supports Dolby Vision, which is important for the best HDR experience in compatible content. Additionally, the TCL S450F has the best input lag score, which can be a notable advantage for reactive gaming. 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.
