If your budget is tight and you want a TV with good quality control and the ability to use it comfortably for various tasks like as a monitor, the LG UQ7570 could be a suitable option. However, its overall picture quality, particularly in bright or dark rooms, is not ideal, making it less suitable for an immersive movie or gaming experience. On the other hand, the TCL R646 is more expensive but offers very good overall picture quality and is especially well-suited for watching movies, playing video games, and viewing in bright rooms. Its better sound quality, higher brightness, and robust HDR support, including Dolby Vision, also contribute to a more engaging viewing experience, with the tradeoff being a higher cost and a narrower viewing angle compared to the LG UQ7570.

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.
