Opting for the LG UQ7570 may suit you if having a TV with a wider viewing angle and better motion processing is a priority, which could enhance group viewing and sports watching experiences. However, it falls short in bright rooms and overall picture quality. Conversely, the TCL S450F stands out with better black uniformity, which can result in a more enjoyable viewing experience for movies in dark rooms. The TCL also has better color accuracy out of the box, so colors may appear more natural. If having more HDMI ports is important for connecting multiple devices, the TCL would be preferable. Both TVs have their limitations with local dimming and HDR brightness, meaning neither is ideal for the best high dynamic range experience. If budget is a concern, the TCL is also slightly less expensive, and it supports both HDR10+ and Dolby Vision, offering more flexibility in HDR content compared to the LG which lacks these features.

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.
