Vizio's 2018 P-Series Quantum offers better overall image quality than its successor - the 2019 P-Series Quantum, while also being much more expensive. The differences between the two TVs are mainly observable in the HDR mode where the 2018 model reproduces much brighter images and has higher contrast.
The P-Series Quantum is one of Vizio's flagship TVs of 2018 and is one of the most versatile options at its price point. It's ideal for people who need a home-theater TV that also works well for both gaming and watching sports. The TV's main weakness is its bad viewing angles, which make it a poor choice for watching in a group.
It offers excellent overall image quality when dealing with both bright and dark scenes. The colors are vibrant because of the TV's high overall brightness and good color accuracy. It's able to produce life-like dark scenes, thanks to its uniform blacks and its ability to dim individual backlight zones. That means that the screen can reproduce bright highlights and inky blacks right next to each other. It's worth noting that this TV can be calibrated to deliver nearly perfect colors. It also has good image processing - by using its interpolation and black frame insertion features it can make content appear smoother and less blurry.
It's also great for consuming HDR content because it has the brightness and color volume needed to take full advantage of the technology. It supports all major HDR formats - HDR10, HDR10+, Dolby Vision, and HLG.
The 2018 P-Series Quantum runs on SmartCast, which is known for being sluggish. It's also missing an app store, which severely limits its functionality. The TV comes with a relatively simple remote that requires no line of sight to control the TV and supports voice commands.
