If you're looking for a more budget-friendly option, the Sony X77L is significantly less expensive and performs adequately in bright rooms. However, if you prioritize picture quality and are willing to invest more, the Vizio Quantum Pro offers better performance overall, especially in bright environments. The Vizio also has a slight edge in gaming but doesn't perform as well as the Sony when watching sports. Both TVs don't excel in very dark rooms, with the Sony performing notably poorer in such conditions. Give Feedback

The Vizio Quantum Pro (LCD) is good for cartoons & animation, while the Sony X77L (LCD) is only fair.
The Sony X77L (LCD) displays fair performance for cartoons and animation due in part to its very good colors out of the box, but limited by a poor color gamut and fair color volume. The Vizio Quantum Pro (LCD) is better suited for these types of content, with a more vibrant and comprehensive color gamut and very good color volume, aiding in a richer, more immersive viewing experience.

The Vizio Quantum Pro (LCD) and Sony X77L (LCD) are both only fair for news, talk, & other TV, though the Vizio Quantum Pro (LCD) is somewhat better.
The Sony X77L performs well in upscaling lower-resolution content and has good color accuracy right out of the box, which is important for clear and vibrant news or talk show visuals. In contrast, the Vizio Quantum Pro has superior SDR brightness, making it a better choice for well-lit rooms, but its out-of-the-box colors and upscaling aren't as refined as the Sony's.

The Vizio Quantum Pro (LCD) is good for bright room, while the Sony X77L (LCD) is only fair.
The Vizio Quantum Pro is superior to the Sony X77L for viewing in a bright room mainly because the Vizio has higher SDR and HDR brightness levels and better handling of reflections, which are crucial for maintaining picture quality in well-lit environments. On the other hand, the Sony X77L has lower brightness levels, both in SDR and HDR content, and fair reflection handling, making it less ideal for bright room viewing.

The Sony X77L (LCD) and Vizio Quantum Pro (LCD) are both only fair for sports.
The Sony X77L has fair motion processing but poor response time, which can affect the clarity of fast-moving sports scenes, while its reflection handling is also fair, potentially reducing visibility in well-lit environments. The Vizio Quantum Pro, on the other hand, offers very good response time which is key for sports clarity but struggles with motion processing which may introduce blur during fast action; it has very good reflection handling but a subpar viewing angle that can limit the view for groups spread around the room.

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 Vizio
Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
