The TCL R648 also performs better in bright rooms and has better sound quality with built-in Dolby Atmos support. On the other hand, the Sony X77L is typically much less expensive and offers a decent all-around performance for various content types. It scores well for sports content and has very good quality control and assurance. However, it may not be the best for dark room viewing due to its lower contrast ratio and local dimming capability.

The TCL R648 (LCD) is good for movies & TV, while the Sony X77L (LCD) is poor.
The Sony X77L is considered poor for watching movies and cinematic TV due to low contrast, ineffective local dimming, and poor black uniformity, which are all critical for a deep, cinematic image. In contrast, the TCL R648 delivers a better experience with a higher contrast ratio, more effective local dimming, and better black uniformity, alongside satisfactory colors and gray uniformity, making it good for movies and cinematic content.

The TCL R648 (LCD) is very good for gaming, while the Sony X77L (LCD) is poor.
The Sony X77L has poor response time making it less ideal for gaming, where fast-paced action requires quick screen updates, whereas the TCL R648 has very good response time, ensuring smoother motion handling which is essential for a responsive gaming experience. Additionally, the TCL R648 also has lower input lag which contributes to a more responsive gaming experience, especially important when precision and timing are key, as opposed to the Sony X77L, which despite having very good input lag, may still not match the performance of the TCL model in this regard.

The TCL R648 (LCD) is very good for cartoons & animation, while the Sony X77L (LCD) is only fair.
The TCL R648 shows very good performance in cartoons & animation due to better colors straight out of the box and a better color gamut, leading to a more vibrant and accurate color depiction. The Sony X77L, while rated as fair, doesn't match the TCL's prowess in color reproduction, which is highly important for animated content that often features wide and varied color palettes.

The TCL R648 (LCD) is good for news, talk, & other TV, while the Sony X77L (LCD) is only fair.
The TCL R648 excels in upscaling content and offers excellent SDR brightness, which makes it particularly suitable for viewing news, talk shows, and other TV programs in various lighting conditions. Conversely, the Sony X77L, despite its fair performance in these respects, has less impressive upscaling and SDR brightness capabilities, which may reduce the clarity and visibility of such content especially in brighter rooms.

The TCL R648 (LCD) is very good for bright room, while the Sony X77L (LCD) is only fair.
The TCL R648 is more suitable for a bright room because it has excellent SDR brightness and very good reflection handling, allowing it to overcome ambient light better than the Sony X77L, which has only good SDR brightness and fair reflection handling. Moreover, the TCL's superior contrast and color volume enhance picture quality in bright conditions, whereas the Sony, despite a similar color gamut, offers lower contrast and color volume, which may affect picture depth and vibrancy in well-lit environments.

The Sony X77L (LCD) and TCL R648 (LCD) are both only fair for sports.
The Sony X77L and the TCL R648 both have fair motion processing capabilities, important for smooth action during sports, but they show weaknesses in response time, which can cause motion blur. The Sony struggles with reflections and has limited viewing angles, detracting from the experience in bright rooms and for viewers sitting off to the side, while the TCL is better at handling reflections but still suffers from narrow viewing angles due to its screen type.

"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."

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.
