Last year's big TV value-hitters were the 2019 TCL 6 Series and the 2019 Vizio M-Series Quantum, and that trend continues into 2020. The 2020 TCL 6-Series impressed us greatly in August via its continued excellence in picture quality and gaming-facing features, but it's also a bit more expensive than the M-Series models. So which one is right for you? As it stands, the M-Series Quantum is an excellent value model, but you'll definitely want to compare it carefully with TCL's 6-Series before pulling the trigger on either. The 6-Series is brighter and offers a higher native refresh rate, making it the more attractive pick for gamers--especially with next-gen gaming consoles on the way.
The P-Series Quantum is positioned between the excellent P-Series Quantum X and the more affordable M-Series Quantum. As you might guess from the naming scheme, almost all of Vizio's 2020 TVs feature quantum dots, microscopic nanocrystals that enhance color saturation. They also all feature full-array local dimming (FALD) backlights, which make for better than average contrast--especially during HDR viewing. Time in the lab revealed something we already assumed: the P-Series Quantum is excellent. In fact, the only reason to spring for the higher-end Quantum X is if you really want top-of-the-line brightness and color performance.
It didn't take long to confirm what I suspected during my Vizio V5-Series review--the slightly more expensive M-Series Quantum offers a far better picture. It's not perfect perfect by any means, but the color is more accurate, and the screen uniformity far outstrips that of the V-Series. If you're shopping mid-range Vizio, the M-Series Quantum is what you want. Skip a couple of lunches to save up the extra cash. The M-Series, including the 55-inch class model M55Q6 that I tested, are 60Hz, 3840 x 2160 (4K UHD), 10-bit TVs.
Last year, Vizio wowed us with its P-series 4K TVs, which delivered premium picture quality at a price much lower than other companies. But Vizio's mid-range M-series sets also gained a reputation for being more affordable while still looking pretty good. This year, things are a bit different. Surprisingly, the 2017 P-series TVs are exactly the same as last year's model. But the newer M-series "XLED" sets received some useful upgrades that will make them even more compelling to shoppers looking for a good deal.
The P Series Quantum is not without its drawbacks, however. Vizio's smart platform--though improved--lacks flexibility, and the TV's acceptable viewing angles aren't as wide as those found on OLEDs. But as far as LED TVs go, there aren't that many that are brighter and more colorful than the Vizio P Series Quantum, and most of them aren't quite as affordable. The 2019 Vizio P Series Quantum is available in two sizes. Here's how each size in the series shakes out, in terms of price: For the most part, different sizes of TVs belonging to the same series perform similarly.
