The Vizio P Series Quantum has a decent full-array local dimming feature. It performs zone transitions relatively well, as it can follow slow-moving objects pretty closely, but it lags when there’s faster movement. While zone transitions are visible when playing our test pattern, it isn’t as bad in regular content.
There’s a fair amount of blooming, more so in regular content than with our test pattern. It tends to make dark areas look grayish or over-brighten dark spots that have some form of light. It isn’t always noticeable, but it can be distracting. Blooming isn’t uniform, as some areas bloom more intensely than others. Unfortunately, subtitles aren’t handled well. They’re very bright, and there’s a lot of blooming around them.
Even though the circle in our test pattern dims a lot when it’s moving around quickly, it doesn’t seem to be an issue in regular content. Unlike the Vizio P Series Quantum 2019, we find almost no difference between the ‘Medium and the ‘High’ setting (local dimming is called Active Full-Array in the settings). The ‘High’ setting, which is the setting that we used, gets a little brighter but doesn’t crush blacks as much as the ‘Medium’ setting.
On the ‘High’ setting, small highlights like stars look okay and aren’t crushed. That said, there’s blooming, and it doesn’t happen on every star, which makes the screen look blotchy.
