The LG C3 OLED is superior in overall picture quality, gaming, dark room performance, and has wider viewing angles, making it great for varied content and room setups. The C3 also offers better motion processing, which is useful for fast-moving content like sports and action movies. On the flip side, the TCL R648 LCD shines in its SDR and HDR brightness, and it supports 8K resolution for future-proofing, albeit with lower scores in gaming, sports, and overall picture quality compared to the C3. The R648 may serve well in very bright rooms due to its brightness. If premium picture quality and gaming performance are paramount and you're okay with spending less, the LG C3 is a strong choice. However, if you prioritize higher brightness and are prepared to pay more, you might lean towards the TCL R648. Give Feedback

The LG C3 (OLED) is excellent for movies & TV, while the TCL R648 (LCD) is good.
The LG C3 OLED offers perfect black uniformity and high contrast, which enhances the depth and realism especially in dark scenes, but its performance may be limited in bright rooms due to lower brightness levels compared to its LCD counterparts. On the other hand, the TCL R648 LCD provides very good brightness which makes it suitable for bright rooms, but its lower contrast and black uniformity could make dark scenes appear less profound and details less discernible. Both deliver wide color gamuts, although the LG C3 OLED may show a slightly better color volume, and viewing angles are superior on the OLED allowing more consistent picture quality when viewed from the side.

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.
