The Sony A90J OLED TV provides exceptional contrast, critical for movie watching, with perfect black uniformity and good local dimming, enhancing dark scenes significantly. However, the TCL R646, despite being an LCD, offers very good contrast and local dimming, albeit with less perfect black levels, while also delivering accurate colors out of the box and a broad color volume, making it a viable, more cost-effective option for cinematic content.

The Sony A90J (OLED) is excellent for sports, while the TCL R646 (LCD) is only fair.
The Sony A90J excels at watching sports due to its OLED panel which provides an excellent response time and top-notch motion processing, resulting in smooth action and wide viewing angles, reflecting light well but not the best for bright rooms. On the other hand, the TCL R646, with its LCD screen, shows motion with more blur due to fair motion processing and response time, struggles more with reflections, and offers a narrower viewing angle, although it is good for various lighting conditions.

"In every meaningful department – motion control, contrast, edge definition, detail levels, you name it the A90J puts in a memorably accomplished shift. In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."

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.
