Between the Sony X85K and the TCL R648, both being LCD TVs, the decision should be influenced by your content preferences and room conditions. If you're particularly interested in a TV that has a wide viewing angle and good reflection handling for bright rooms, the Sony X85K would serve you well. However, if you are looking for superior picture quality for watching movies or HDR content due to a better contrast ratio and full-array local dimming, the TCL R648 would be a better fit. Keep in mind that the TCL R648 won't perform as well as the Sony in bright rooms. Give Feedback

The TCL R648 (LCD) is good for movies & TV, while the Sony X85K (LCD) is only fair.
The Sony X85K exhibits good contrast and black uniformity, but lacks local dimming, which affects its ability to enhance contrast in movies and cinematic TV, especially in dark scenes. On the other hand, the TCL R648 also has good contrast and black uniformity and includes local dimming, which helps improve the viewing experience by deepening blacks and improving contrast, making it more suitable for those aspects.

The Sony X85K (LCD) is good for sports, while the TCL R648 (LCD) is only fair.
The Sony X85K outperforms the TCL R648 in sports viewing primarily because of its superior motion processing, ensuring smoother movement and less blur during fast action. However, the TCL R648 has better handling of reflections, which can be advantageous in bright rooms, but falls short with a lower motion processing capability, affecting fast-paced sports clarity.

The Sony X85K (LCD) is very good for news, talk, & other TV, while the TCL R648 (LCD) is good.
The Sony X85K performs very well at upscaling lower resolution content, which is essential for watching standard-definition programs like news or talk shows, and it offers excellent colors right out of the box, meaning less adjustment is needed for accurate representation. On the other hand, the TCL R648 shines with its excellent SDR brightness, making it a great option for brightly lit rooms, but its upscaling is not at the same level as the Sony X85K, which may affect the picture quality of lower resolution channels.

The TCL R648 (LCD) and Sony X85K (LCD) are both very good for cartoons & animation.
The Sony X85K is highly regarded for cartoons and animation because of its excellent color reproduction straight out of the box which enhances the viewing experience without the need for additional calibration. Both TVs have qualities important for animation, but Sony's out-of-the-box color settings might be more convenient for those who prefer not to adjust their TV's settings extensively.

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
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.
