The LG B1 OLED TV offers exceptional dark room performance and very low input lag, making it an excellent choice for gaming and watching movies in darker environments. Its viewing angle is also wider, which is advantageous for rooms where people will be sitting at various angles to the screen. On the downside, it is pricier and doesn't perform as well in bright rooms. On the other hand, the TCL QM8 LCD TV is less expensive and offers superior bright room performance, which makes it a better fit for well-lit spaces. It features a higher color volume, making it great for vibrant cartoons and animations, though it falls short in terms of viewing angles and sports content display. Both TVs support various HDR formats and can be suitable for general viewing and gaming. Give Feedback

The LG B1 (OLED) and TCL QM8 (LCD) are both very good for movies & TV, though the LG B1 (OLED) is somewhat better.
The LG B1 OLED stands out for watching movies and cinematic TV due to its perfect contrast and black uniformity, accentuating dark scenes without any halo effect around bright objects, a common strength of OLEDs. The TCL QM8 LCD, on the other hand, excels with its wide color volume and impressive local dimming feature, although its overall contrast and black level performance is not as strong as the B1's due to the inherent limitations of LCD technology compared to OLED.

The LG B1 (OLED) is very good for sports, while the TCL QM8 (LCD) is only fair.
The LG B1 OLED TV excels in sports viewing due to its superior response time and wide viewing angles, meaning fast-moving action is displayed with minimal blur and the picture remains accurate when seen from the side. In contrast, while the TCL QM8 LCD TV has good motion processing, its viewing angles are not as broad, so the picture quality may degrade when viewed from an angle, and its response time isn't quite as swift, which is more noticeable during fast sports action.

The LG B1 (OLED) and TCL QM8 (LCD) are both very good for gaming, though the LG B1 (OLED) is somewhat better.
The LG B1 OLED excels for gaming with an excellent response time and very good input lag, ensuring minimal motion blur and snappy on-screen action. Conversely, the TCL QM8 LCD also has a very good response time and good input lag, which is suitable for gaming but may not be as fluid as the LG B1 in fast-paced games.

The TCL QM8 (LCD) and LG B1 (OLED) are both very good for cartoons & animation, though the TCL QM8 (LCD) is somewhat better.
The LG B1 OLED's exceptional color gamut and accurate colors out of the box make it well-suited for vivid and consistent animation viewing, while the TCL QM8 LCD's strength lies in its excellent color volume, ensuring a wide range of colors even at different brightness levels, which enhances the perception of colorful cartoons and animation. Both TVs are designed to provide a good cartoon and animation watching experience, but the LG B1 may have an edge in producing more uniform grays and deep contrast, useful for animated content's varied scenes, and the TCL QM8 offers brighter SDR brightness, beneficial for viewing in well-lit rooms.

The LG B1 (OLED) is very good for news, talk, & other TV, while the TCL QM8 (LCD) is only fair.
The LG B1 excels in upscaling lower resolution content and provides better SDR brightness compared to the TCL QM8, which is crucial for clarity when watching news and TV programs. However, while the B1 offers better performance in these areas, the TCL QM8 may produce richer colors out of the box, but it tends to fall behind in both upscaling and overall brightness, affecting its suitability for daytime viewing in bright rooms.

The TCL QM8 (LCD) is best in class for bright room, while the LG B1 (OLED) is good.
The TCL QM8 LCD's best SDR and excellent HDR brightness levels make it optimal for bright room viewing, and it handles reflections very well, favorable for environments with many light sources. On the other hand, while the contrast on the LG B1 OLED is superior and it has excellent reflection handling, its brightness levels in SDR and HDR are comparatively lower, which might make it less suitable than the TCL for brightly lit rooms.

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.
