The LG B2 OLED offers exceptional picture quality in both dark and well-lit rooms, with excellent contrast and wide viewing angles. This makes it ideal for movies and general TV watching in various lighting conditions. Its low input lag and fast response time also make it a great choice for gaming. In contrast, the TCL QM8 LCD shines brighter in bright rooms and has a good dark room performance, but it falls short when it comes to viewing angles, which could limit the viewing experience for groups. It does better with sports content than the LG B2 but is less suited for movies and general viewing in dark environments. Choose the LG B2 OLED if you prioritize overall picture quality and gaming, especially in mixed or dark room conditions. Opt for the TCL QM8 LCD if you value brightness in a well-lit room but are willing to compromise on viewing angles and some content quality in darker settings. Give Feedback

The LG B2 (OLED) is excellent for movies & TV, while the TCL QM8 (LCD) is very good.
The LG B2, an OLED TV, is rated as "excellent" for watching movies and cinematic TV due to its perfect contrast, effective local dimming, and supreme black uniformity. On the other hand, the TCL QM8, a Mini-LED LCD TV, is regarded as "very good" for the same content with strong contrast and local dimming, but its overall black uniformity and narrower viewing angles don't match the OLED performance.

The LG B2 (OLED) is very good for sports, while the TCL QM8 (LCD) is only fair.
The LG B2 excels at displaying sports due to its superior motion processing and faster response time, minimizing blur during fast action, and offering wide viewing angles which keep the picture consistent when seen from the side. On the other hand, the TCL QM8 struggles more with motion handling and has narrower viewing angles, making it less ideal for a group watching sports together or from different positions.

The LG B2 (OLED) and TCL QM8 (LCD) are both very good for gaming, though the LG B2 (OLED) is somewhat better.
The LG B2 OLED TV is highly regarded for gaming due to its best response time and very good input lag, which ensures smooth motion and quick on-screen reaction to inputs. Comparatively, the TCL QM8 LCD also offers very good gaming performance with very good response time and good input lag, providing a responsive gaming experience, though not as swift as the LG B2 in terms of response time.

The LG B2 (OLED) is very good for news, talk, & other TV, while the TCL QM8 (LCD) is only fair.
The LG B2 OLED TV's very good upscaling and good SDR brightness make it well-suited for watching news and talk shows, where high-fidelity presentation of lower-resolution content and a competent brightness in well-lit rooms are crucial. In contrast, the TCL QM8 LCD may offer the best SDR brightness which is excellent for bright rooms, but with only fair upscaling capability, the quality of lower-resolution content such as standard definition TV shows or news broadcasts may not be as refined.

The TCL QM8 (LCD) is best in class for bright room, while the LG B2 (OLED) is good.
The TCL QM8 is better suited for watching TV in a bright room due to its superior SDR and HDR brightness performance, as well as effective handling of reflections. In comparison, while the LG B2 offers exceptional contrast, color volume, and color gamut, its SDR and HDR brightness are lower and it might not handle reflections as well as the TCL QM8, making it less optimal for bright rooms.

Tom's guide
Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."

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.
