The Vizio MQ6 '23 offers a better overall picture quality and is more affordable than the Sony X77L. The Vizio delivers superior performance in dark rooms and has better contrast, which is beneficial for movies and dramatic content. It also scores higher in upscaling and has a lower input lag that can be particularly appealing for gamers. On the other hand, the Sony X77L, while more expensive, offers a better bright room performance, making it a preferable choice if you're going to watch TV in a well-lit environment. It also has a better viewing angle, meaning the picture remains consistent from different seating positions. Both TVs have the same sound quality, and neither has great built-in speakers; considering adding a soundbar or external speakers for a more immersive audio experience. They also both support high dynamic range formats like Dolby Vision and HLG, enhancing the viewing experience with compatible content. Give Feedback

Milton Clark | September 2023
"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 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.
