The Vizio Quantum Pro (LCD) is only fair for movies & TV, while the Sony X80K (LCD) is poor.
The Sony X80K is considered poor for movies and cinematic TV due to its lower contrast ratio and absence of local dimming, both crucial for deep blacks, while Vizio Quantum Pro fares better with a higher contrast and functional local dimming which enhances dark scene reproduction. However, both TVs may not display the most accurate colors right out of the box and can suffer from narrow viewing angles, impacting group movie nights.

The Sony X80K (LCD) is good for sports, while the Vizio Quantum Pro (LCD) is only fair.
The Sony X80K is better for watching sports since it has good motion processing and fair reflection handling, critical for fast action and bright rooms. In contrast, the Vizio Quantum Pro, while handling reflections very well, only offers fair motion processing, which may not be as smooth for fast-paced sports action.

The Vizio Quantum Pro (LCD) is very good for gaming, while the Sony X80K (LCD) is poor.
The Sony X80K has a fair response time and fair input lag, which may result in noticeable delays and less crisp motion clarity, not ideal for gaming. In contrast, the Vizio Quantum Pro offers very good response and input lag performance, providing a smoother gaming experience with minimal delay between input and action on the screen.

The Sony X80K (LCD) is good for news, talk, & other TV, while the Vizio Quantum Pro (LCD) is only fair.
The Sony X80K offers better upscaling and out-of-the-box color settings, which is good for watching news and TV programs in environments that aren't overly bright. In contrast, the Vizio Quantum Pro, despite having better SDR brightness which is beneficial for bright room usage, might not deliver as natural colors without calibration, and its upscaling is not as refined, making it less suitable for standard definition content commonly found in news and talk shows.

The Vizio Quantum Pro (LCD) is good for bright room, while the Sony X80K (LCD) is only fair.
The Vizio Quantum Pro performs better in a bright room mainly due to its higher SDR and HDR brightness, which means it can better maintain visibility in well-lit environments. Additionally, it handles reflections more effectively than the Sony X80K, making the screen easier to see when there are sources of light in the room. Contrast, color volume, and color gamut are somewhat important, with the Vizio having better scores in color gamut and volume, contributing to more vibrant and varied colors in various lighting conditions.

Tom's guide
Matthew Murray | February 2023
"The Sony Bravia X80K is an inexpensive LCD TV that turns out pleasing visuals and is armed with a number of other desirable features. Sony’s robust internal processing, results in generally better picture quality than you’ll usually get for this price. In practice, the X80K is satisfying to watch. You’re not going to get as sumptuous a picture as you may with other TVs from Sony or other companies, but we didn’t encounter anything that looked bad on it."

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 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.
