Considering the LG B3 is significantly more expensive than the TCL Q7, here are the tradeoffs: The LG B3, being an OLED TV, will offer superior contrast and black levels, which is excellent for movies and viewing in a dark room. It will also have wider viewing angles, making it better for larger gatherings. On the other hand, the TCL Q7, with an LCD screen, is usually less expensive and will perform better in bright rooms due to its higher brightness capabilities, which is great for daytime TV watching or sports. The TCL Q7 may also be a better choice for gaming due to its support for a higher refresh rate, which can reduce motion blur and make fast-paced games look smoother. However, if picture quality, particularly for movies and cinematic content, is your priority and budget is less of an issue, the LG B3's OLED panel may be the better choice despite the higher price.

The LG B3 (OLED) is excellent for movies & TV, while the TCL Q7 (LCD) is good.
The LG B3 OLED provides an exceptional contrast with perfect black uniformity, critical for deep blacks in dark movie scenes, and a wide viewing angle, preserving picture quality at different seats, whereas the TCL Q7 LCD offers lower contrast and black uniformity leading to less impressive dark scenes and reduced viewing angles, which could affect off-center viewing. Despite this, the TCL's colors out of the box and color volume are rated good, similar to the LG's, offering a vibrant picture for movies and TV without the need for extensive calibration.

The LG B3 (OLED) is very good for news, talk, & other TV, while the TCL Q7 (LCD) is only fair.

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.
