When choosing between the LG B3 OLED and the TCL R648 LCD, consider that the LG B3 may offer a better viewing experience in darker rooms due to its OLED technology, which tends to have superior contrast and black levels compared to LCDs. The OLED TV is also typically more affordable than the TCL R648. However, the TCL R648, while often more expensive, may perform better in bright rooms and has a higher brightness peak which is beneficial when watching content with a lot of HDR impact. It also has a Mini LED backlight, making it capable of great local dimming performance. For gaming, both TVs have similar features like a 120Hz panel and HDMI 2.1 support, but keep in mind that the TCL has a VA panel with potentially better reaction to fast-moving objects, useful for fast-paced games and sports. Lastly, if you're interested in the latest resolution standards, the TCL R648 supports 8K, whereas the LG B3 is a 4K TV. Give Feedback

The LG B3 (OLED) is excellent for movies & TV, while the TCL R648 (LCD) is good.
The LG B3, being an OLED TV, delivers perfect black uniformity and contrast with superior local dimming, which provides an exceptional experience for watching movies and cinematic content, paired with wide viewing angles that maintain color accuracy when seen from off-center. On the other hand, the TCL R648, as an LCD with miniLED technology, also offers good performance for movies with decent local dimming and contrast, but it cannot match the OLED's perfect blacks and has narrower viewing angles that could result in color and contrast shifts when not viewed straight on.

The LG B3 (OLED) is very good for sports, while the TCL R648 (LCD) is only fair.
The LG B3 (OLED) is better for sports due to its excellent response time, which reduces motion blur, and wide viewing angles that keep the image consistent when viewed from the side, along with better handling of reflections. The TCL R648 (LCD), while fair for sports, has lower performance in these areas, with a very good response time that can introduce more blur during fast action and a narrower viewing angle which can result in color and brightness shifts when not viewed head-on, along with lower performance in reflections handling despite its good gray uniformity.

The LG B3 (OLED) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The LG B3 OLED excels in upscaling and has very good performance with colors out of the box, which makes it very suitable for watching standard definition content like news and talk shows with true-to-life colors. On the other hand, the TCL R648 LCD shows stronger SDR brightness, which is beneficial for viewing in well-lit rooms, yet it may not upscale lower-resolution content as effectively and could deliver colors that are less accurate straight out of the box.

The TCL R648 (LCD) is very good for bright room, while the LG B3 (OLED) is good.
The TCL R648 delivers a brighter image in both SDR and HDR, which is more suitable for viewing in a bright room, whereas the LG B3 offers good brightness but exceptional reflection handling, meaning it effectively reduces glare in well-lit environments. However, the TCL R648's higher brightness levels can better overcome ambient light, which might make it preferable for very bright settings.

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.
