Our Verdict
Vizio P Series Quantum X 2019
Vizio M Series Quantum 2019
The Vizio P Series Quantum X 2019 is a slightly better TV than the Vizio M Series Quantum 2019 for most uses. The Quantum X looks more premium and well-built and has a few more input options. It's a much better choice if you watch a lot of HDR movies or game in HDR, as its screen can get significantly brighter, especially with HDR content. Its brighter screen also makes it better suited for very well-lit rooms as it shows much fewer reflections. On the other hand, the M Series Quantum has better black uniformity, much more accurate colors out of the box, much better gradient performance, and better built-in speakers.
