The LG G1 is an OLED TV that offers superior picture quality, better gaming performance, and excellent dark room performance compared to the TCL R648, which is an LCD TV. However, the LG G1 comes at a higher price. The LG G1 also has better viewing angles and handles reflections well, making it a good choice for a room with various seating positions and some ambient light. On the other hand, the TCL R648 has a brighter screen which is beneficial for bright room viewing, but it doesn't perform as well in a dark room, nor does it handle colors and contrasts as richly as the LG G1. If budget considerations are important and you have a well-lit room, the TCL R648 might be the right choice for you. It also supports high-resolution content up to 8K, unlike the LG G1 which supports up to 4K resolution. Both TVs support major HDR formats including Dolby Vision and HDR10. Give Feedback

The LG G1 (OLED) is excellent for movies & TV, while the TCL R648 (LCD) is good.
The LG G1 OLED excels in movie watching with perfect blacks due to its OLED technology that allows for infinite contrast and exceptional black uniformity, and wide viewing angles that keep colors accurate from different seating positions. Meanwhile, the TCL R648 LCD, while offering good color accuracy out of the box and adequate contrast, falls behind in black uniformity and has a narrower viewing angle, which can impact the viewing experience from off-center seats.

The LG G1 (OLED) is very good for sports, while the TCL R648 (LCD) is only fair.
The LG G1 excels in sports watching due to its OLED technology, which provides superior response time, handling fast motion effortlessly, and greater viewing angles allowing a clear view from different seating positions; it also manages reflections exceptionally well, critical for bright rooms. On the other hand, the TCL R648, though fair for sports, may exhibit slower response times leading to motion blur during fast-paced games, more limited viewing angles which can affect off-center watching, and less effective reflection handling which is noticeable in well-lit environments.

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.
