If you prioritize saving money and want a TV that performs well for gaming and watching sports, the LG NANO90 could be suitable for you. However, this TV might not be the best for dark room viewing due to its lower dark room performance. On the other hand, the TCL R646 is pricier, but offers better overall picture quality, particularly for dark room viewing, which makes it a good option for movies. Still, both TVs have similar gaming capabilities, and neither is exceptional for sunny room usage. Choose the LG for cost savings or the TCL for a bump in dark room viewing quality. Give Feedback

The TCL R646 (LCD) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 shows poorer performance in color accuracy "out of the box" and has a more limited color gamut, which are vital for vibrant animations, while the TCL R646 is noted for its good color performance right out of the start and higher color gamut, resulting in richer and more varied colors for animated content. Additionally, the better color volume of the TCL R646 enhances the display of different shades, contributing to its very good reputation for watching cartoons and animation.

The TCL R646 (LCD) is very good for bright room, while the LG NANO90 (LCD) is only fair.
The TCL R646 performs better in bright rooms due to its superior SDR and HDR brightness which helps to maintain picture quality in well-lit conditions, along with better handling of reflections which reduces glare. The LG NANO90, while still providing a good experience, has lower brightness and contrast, and despite its very good reflection handling, may not be as suitable for very bright rooms as the TCL R646.

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.
