The TCL QM8 is often significantly less expensive and offers better overall picture quality, making it well-suited for movies and streaming content. However, it may not perform as well in very bright rooms. If you prioritize overall picture quality and cost savings, the QM8 may be the better option for you. On the other hand, the TCL R648 is more expensive and delivers excellent sound quality with its great speakers, making it a good choice if you value audio performance. It also supports a higher resolution of 8k compared to the QM8's 4k. If you are willing to invest more for better sound and future-proofing with 8k resolution, consider the R648. Give Feedback

The TCL QM8 (LCD) is very good for movies & TV, while the TCL R648 (LCD) is good.
The TCL QM8 provides excellent contrast, superior local dimming, and better black uniformity, which makes it very good for watching movies and cinematic TV, featuring deep blacks and stark contrasts necessary for a richer viewing experience. Meanwhile, while the TCL R648 also offers good local dimming and contrast, it falls short in black uniformity compared to the QM8, making it less ideal but still sufficient for those immersive movie sessions.

The TCL R648 (LCD) is good for news, talk, & other TV, while the TCL QM8 (LCD) is only fair.
The TCL R648 excels in upscaling content and provides brighter SDR quality, both very important for watching news and TV programs, enhancing clarity and visibility especially in brightly lit rooms. In contrast, the TCL QM8, while still performing well with a fair upscaling capability, does not match the brightness levels of the R648, which could result in slightly less vivid images under similar conditions.

The TCL QM8 (LCD) is best in class for bright room, while the TCL R648 (LCD) is very good.
The TCL QM8 outshines the R648 in SDR and HDR brightness while handling reflections similarly well, making it more suitable for bright rooms. While both models have similar performance in terms of contrast and color, the QM8's higher brightness may provide a more vibrant picture in well-lit environments.

The TCL R648 (LCD) and TCL QM8 (LCD) are both only fair for sports.
Both the TCL QM8 and TCL R648 have response times and motion processing that are adequate for sports, but not excellent; this could lead to some blur during fast-paced games. The QM8 offers a slightly better reflections handling which is helpful in well-lit rooms, but both have limited viewing angles that could reduce picture quality when watching from the side; the QM8 has a slight edge in gray uniformity, important for displaying sports fields without uneven shades.

The TCL QM8 (LCD) and TCL R648 (LCD) are both very good for cartoons & animation.
The TCL QM8 is praised for cartoons & animation due to its very good color gamut, ensuring a wide range of vibrant hues, while its colors out of the box are rated as good, indicating minimal need for calibration. In contrast, the TCL R648, while rated excellent for colors out of the box, offering an immediate optimized color experience, has a slightly lesser color gamut, which means it might not display as wide a range of colors as the QM8.

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.
