If your primary concern is overall picture quality for movies and you often watch in darker environments, the TCL S546 would be a better fit as it performs well in those areas. However, if you plan on using the TV in a bright room and value good viewing angles, for say, a family gathering where people are seated at different angles to the TV, then the LG UQ7570 might serve you better despite its lower picture quality because of its higher bright room performance and wider viewing angles. Both TVs have their limitations when it comes to gaming and sports content, with the TCL S546 performing slightly better. For connectivity, the TCL has an additional HDMI port. Neither option excels in sound quality, so if audio is important to you, consider a separate sound system regardless of the TV you choose. Keep in mind, the TCL model also supports a wider range of HDR formats which could enhance your viewing experience if you watch a lot of varied HDR content. 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.
