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

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.
