The LG B1 (OLED) is considered a premium TV and typically costs significantly more but offers better overall picture quality, especially in dark rooms, and has excellent gaming performance. Its OLED screen provides perfect black levels and wide viewing angles but can struggle in very bright rooms.
On the other hand, the TCL Q7 (LCD) is usually much less expensive, and while it may not match the LG B1 in picture quality, it still delivers good performance and supports gaming well. It has a brighter screen which might be better for viewing in well-lit rooms, but its viewing angles are narrower compared to the LG B1.
If picture quality, especially in darker environments, and gaming are your priorities, and budget is less of a concern, the LG B1 could be a better choice. If cost is a significant factor and you often watch TV in bright rooms, the TCL Q7 might suit you better. Give Feedback

The LG B1 (OLED) is very good for movies & TV, while the TCL Q7 (LCD) is good.
The LG B1 (OLED) excels in watching movies and cinematic content mainly due to its perfect black uniformity and contrast, as OLEDs can turn off individual pixels for true blacks, resulting in exceptional local dimming performance. On the other hand, while the TCL Q7 (LCD) still delivers a good experience with commendable black uniformity for an LCD, its local dimming and contrast aren't as refined as the LG B1, impacting its overall ability to display deep blacks and high contrast scenes.

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.
