If viewing quality in bright rooms and for watching sports is important, the LG NANO90 would be a better choice as it has a higher score in both bright room performance and for sports content. However, it is less suited for dark room viewing compared to the TCL R648. The TCL R648, with its premium price, offers better overall picture quality, making it a superior choice for movies and series. Additionally, it performs better in dark rooms, comes with better speakers, and supports more features, like higher resolution content. Both TVs have a similar gaming performance, but the TCL R648 slightly edges out. It also has a lower color score out of the box, which may require calibration for optimal performance. Both TVs support similar HDR formats but the LG NANO90 may not handle HDR content as well as the TCL R648 due to lower contrast and HDR brightness. Consider your budget and prioritize what content you'll be viewing most when making your choice. Give Feedback

The TCL R648 (LCD) is very good for bright room, while the LG NANO90 (LCD) is only fair.

"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.
