The LG QNED90 is a premium choice with better overall picture quality, making it suitable for varied content like gaming, sports, and watching movies in both dark and bright rooms. Its better gaming performance is thanks to low input lag and swift response time. However, if budget is a concern and your viewing consists mainly of news or casual TV shows, the TCL S450F, while offering lower picture quality across the board, is significantly more affordable. It has excellent black uniformity but falls short in gaming, sports, and is less ideal for bright room viewing. The LG's wider color gamut and local dimming feature will provide a more vibrant and dynamic viewing experience, whereas the TCL may appear less impressive in these aspects. The choice between the two relies on balancing the importance of cost against the desire for higher performance and better picture quality. Give Feedback

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.
