The decision between the LG QNED90 and the TCL R648 depends on your preferences and viewing habits. If you prioritize gaming performance, either TV will serve you well, but the LG has a slight edge in response time. For those who watch a lot of movies or series in darker environments, the TCL R648 offers better dark room performance due to its higher contrast and better black uniformity, enhancing the viewing experience. However, if you are going to watch TV in bright rooms, the LG QNED90 has a slightly higher bright room performance, which means it could handle reflections and maintain visibility slightly better in well-lit conditions. The TCL R648 generally offers superior picture quality and color accuracy, which could be more appealing for movie enthusiasts. Consider the TCL R648 if you value superior dark room viewing and overall picture quality and are willing to pay a higher price. Choose the LG QNED90 if you're looking for a more cost-effective option that performs slightly better for gaming and in brightly lit rooms. Give Feedback

Although they have very similar scores, PerfectRec considers LG QNED90 (LCD) to be very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The LG QNED90 is very good for watching news, talk shows, and other TV programs thanks to its very good SDR brightness and effective upscaling, which ensures that it can handle lower resolution content typically found in such programs with clarity. The TCL R648, while good in the same viewing scenarios, excels with excellent color accuracy straight out of the box, which means colors in any content will look very vibrant and true to life, but it may fall behind the LG QNED90 in SDR brightness and upscaling ability, impacting its performance slightly in comparison when displaying standard dynamic range or lower resolution content.

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.
