The LG B2 is an OLED TV with superior overall picture quality, contrast, and viewing angles which makes it excellent for movies and gaming, even in dark rooms. However, it is not as bright as the TCL R648, so it might not perform as well in very bright rooms. The B2 also has a lower sound quality compared to the R648 and does not have great built-in speakers. The TCL R648 is an LCD TV with Mini-LED technology, making it brighter for better performance in well-lit rooms, and it has better sound quality with more powerful speakers. It's generally more expensive and doesn't provide as wide viewing angles or the perfect blacks like the LG's OLED. If you watch a lot of sports, the TCL might not be as smooth in motion handling. If you prioritize top-notch picture quality for movies and gaming, prefer perfect blacks, and typically watch TV in dimmer conditions, the LG B2 could be the better choice. If you usually watch TV in a bright room and value brighter image and better sound without external speakers, you might prefer the TCL R648, despite its higher cost. Give Feedback

The LG B2 (OLED) is excellent for movies & TV, while the TCL R648 (LCD) is good.
The LG B2 excels in movie and cinematic TV viewing primarily due to its perfect black uniformity and excellent contrast, which are crucial for dark scenes, and it also has wide viewing angles that preserve picture quality at an angle. In comparison, while the TCL R648 has good contrast and is bright, its black uniformity and viewing angles are inferior, which can affect the fidelity of cinematic content, especially when viewed off-center.

Tom's guide
Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."

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.
