The LG UP8000 is often significantly less expensive than the Vizio M-Series. If your budget is tight, LG UP8000 may be the way to go. However, the Vizio M-Series offers superior picture quality overall, making it a better choice for watching movies or TV series. The Vizio M-Series also has better performance in dark rooms, which can enhance viewing experiences in low-light conditions. For gaming, the LG UP8000 has slightly better performance, so if that's a priority, you might lean towards the LG. When it comes to bright rooms, both TVs are quite close in performance, but the LG UP8000 is rated slightly higher, though the difference may not be significant based on your viewing conditions. If you're after more advanced features like HDR10+ and Dolby Vision, which can improve picture quality for compatible content, the Vizio M-Series supports them, while the LG UP8000 does not. Additionally, the Vizio comes with one more HDMI port, which can be convenient if you have multiple devices to connect. In summary, choose the LG UP8000 for a lower cost and slightly better gaming performance, or opt for the Vizio M-Series for better movie watching and advanced HDR features at a higher price point.

The Vizio M-Series (LCD) is good for movies & TV, while the LG UP8000 (LCD) is poor.
The Vizio M-Series is good for watching movies and cinematic TV because it has a much higher contrast and effective local dimming which results in deeper blacks and more detailed dark scenes, while the LG UP8000 falls short with lower contrast and lack of local dimming, causing grayer blacks and less picture depth. Additionally, the Vizio M-Series exhibits better black uniformity, enhancing the overall picture quality, unlike the LG UP8000 which has poorer black uniformity, detracting from the movie-watching experience.

The Vizio M-Series (LCD) is only fair for gaming, while the LG UP8000 (LCD) is poor.
The LG UP8000 has a fair response time but offers the best input lag, meaning it's better for responding quickly to gaming controls, whereas the Vizio M-Series also has a fair response time but a very good input lag, meaning it's slightly slower at responding to gaming inputs but offers a more responsive feeling than the LG. Both have the same refresh rate, but it's the balance between response time and input lag that gives the Vizio an edge for a fair gaming experience compared to the LG's poor rating.

The Vizio M-Series (LCD) is very good for cartoons & animation, while the LG UP8000 (LCD) is poor.
The Vizio M-Series is very good for watching cartoons & animation because it has very good colors right out of the box and a very good color gamut, ensuring a wide range of vivid and accurate colors. On the other hand, the LG UP8000 is poor in these aspects with only fair color volume and poor color gamut, leading to less impressive color reproduction for animated content.

The Vizio M-Series (LCD) is good for news, talk, & other TV, while the LG UP8000 (LCD) is only fair.
The LG UP8000 has fair SDR brightness and colors out of the box, but it lacks local dimming, affecting contrast quality, which makes it less suited for a well-lit room when watching news or talk shows. In comparison, the Vizio M-Series offers good SDR brightness and very good colors out of the box, along with effective local dimming and a better contrast, making it a better choice for clearer viewing in similar conditions.

The Vizio M-Series (LCD) is only fair for bright room, while the LG UP8000 (LCD) is poor.
The LG UP8000 struggles in bright rooms primarily because it has lower performance in key areas such as SDR brightness and reflections handling compared to the Vizio M-Series, which has better SDR and HDR brightness and decent handling of reflections. Additionally, while both have limitations in HDR brightness and contrast, the overall color performance of the Vizio M-Series with its superior color volume and gamut makes it more suitable for brighter environments than the LG UP8000.

The LG UP8000 (LCD) and Vizio M-Series (LCD) are both only fair for sports.
The LG UP8000's response time is decent for watching sports, but its motion handling is not as impressive, which means that fast-paced sports action might not be as smooth. On the other hand, the Vizio M-Series also has a fair response time but with inferior motion processing capabilities, which can result in even less smoothness in sports scenes, and its limited viewing angles can make it less ideal for group viewings.

"What we liked on this one was the very sharp 4K images it could display, its good up-scaling capabilities, nice viewing angles and extremely low input lag. Lastly the new webOS 6.0 is great even if it needs some time to get your bearings while the redesigned Magic Remote feels fresh even if functionality remains the same."
