The LG NANO75 is a lower midrange priced TV, offering a decent overall picture quality with a particularly good performance for viewing sports content. It will not perform as well in a dark room, and its bright room performance is average. For gaming, it's suitable but not exceptional. On the other hand, the TCL R646 costs more but delivers better overall picture quality, excels at gaming with high responsiveness and low input lag, and has superior dark room performance. It also handles bright room conditions very well. If budget is a major consideration and sports content viewing is a priority, LG NANO75 may be more appropriate. For a better gaming experience and higher quality in both bright and dark environments, the TCL R646 would be a better choice despite the higher price. Give Feedback

The TCL R646 (LCD) is very good for cartoons & animation, while the LG NANO75 (LCD) is poor.
When watching cartoons and animation, the TCL R646 outperforms the LG NANO75 due to the R646's superior color gamut and volume, making colors appear more vivid and accurate. Additionally, the R646 delivers better contrast and brightness, which are beneficial for animation, while the NANO75 falls short in these areas, leading to less vibrant and flat images.

The TCL R646 (LCD) is good for news, talk, & other TV, while the LG NANO75 (LCD) is only fair.
The LG NANO75 has poor upscaling and SDR brightness performance, which might not provide the clearest picture for watching news and TV programs, but its wide viewing angles would be advantageous in a room where viewers are seated off to the side. On the other hand, the TCL R646 has excellent SDR brightness and better quality local dimming, which contributes to sharper and more vibrant images, making it a better choice for viewing content directly in front, but its viewing angles are more limited.

The TCL R646 (LCD) is very good for bright room, while the LG NANO75 (LCD) is poor.
The LG NANO75 struggles in bright rooms due to its poor SDR and HDR brightness and only good reflections handling, while the TCL R646 excels in these environments with its excellent SDR brightness, very good HDR brightness, and very good reflections handling, meaning it maintains picture quality even in well-lit spaces. Contrast, color volume, and color gamut are also factors, where the TCL R646 performs better overall, affecting how vibrant and deep the picture appears.

The LG NANO75 (LCD) and TCL R646 (LCD) are both only fair for sports.
The LG NANO75 has a fair response time and motion processing, which are very important for watching sports, and its reflection handling is good, but it has a wider viewing angle, which can be beneficial for larger groups. The TCL R646, while having a very good response time that is beneficial for fast motion in sports, falls short with only a fair motion processing performance and has a lower reflection handling score and narrower viewing angles compared to the LG NANO75. Both TVs exhibit only fair gray uniformity, which is somewhat important and can affect the viewing experience when watching sports.

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.
