Why We Like It – Vizio M558-G1 M-Series Quantum 55 Inch TV

From Vizio’s collection of M-Series TVs, the Vizio M558-G1 M-Series Quantum 55 Inch TV, with its quantum color technology, has a brighter picture and deeper shades than other smart TVs on the market. Not only does it stream from the most popular apps, but you can also control your TV with your favorite voice app: Alexa, Google, and Siri.

Pros
  • Voice control technology
  • High 120 hertz refresh rate
  • Dolby HDR has millions of distinguishable colors
Cons
  • Less dimming zones than other 4K TVs
  • Amazon reviews note the TV turns itself on randomly

Performance/Display/Resolution/Refresh

With its Quantum Dots technology, the Vizio M558 G1 delivers more color than other 4K TVs currently on the market, running the full color gamut. It has 600 nits of peak brightness, supporting HDR content and incredible picture quality with Dolby Vision and HDR10 Dolby tech. With a refresh rate of 120 hertz, you’ll have hyper-realistic sports games or an incredible gaming experience. Its Active Full Array backlight technology allows for deeper and richer color, and beautiful contrast. However, keep in mind that the Vizio M Series has only 90 local dimming zones, compared to the Vizio P Series’ 200 dimming zones. You can compare the Vizio TV to the Samsung 50-Inch Class Crystal UHD TU-8000 Series – 4K UHD HDR Smart TV. Or, you can check out our Vizio P Series Quantum review.

Sound

The Vizio M558 has built-in speakers with Dolby Digital Plus audio. However, the sound is fairly basic, and Amazon reviewers suggest using an external soundbar to have a richer audio experience. If you like TVs with excellent sound, check out our Vizio M Series Quantum review.

Smart Features

The best part of the Vizio M558’s design is the award-winning SmartCast technology, allowing you to control the TV with just your voice. It supports the top voice technology (Siri, Alexa, and Google) so you can stream specific movies, switch the channel, control the volume, and even show a picture slideshow. All with just your voice! You can even browse streaming sites like Netflix and Disney+ directly on the TV or in the connected app. The voice technology is directly comparable to the LG CX OLED model.

Ports/Expandability

The Vizio M558 has 4 HDMI ports, more than others in its price range. It also has an ethernet port to connect directly to the internet (if you don’t want to just use wifi) and a USB port (for loading pictures and other media directly onto the screen).

Value

Vizio TVs are known for having some of the lowest Smart TV prices on the market. They’re a tried and true cheaper brand, and definitely not as expensive as something like the Sony A8H OLED.The value in the Vizio M558 has to be the built-in Chromecast and voice control technology. Being able to just use your smartphone or even your voice as a remote control is incredibly convenient. And there are even hundreds of live TV channels built right into the TV, so there’s no need for cable, a big savings!

It has a full color gamut with great brightness, and a fast 120 hertz refresh rate that will make your living room feel like front-row seats to the Super Bowl. One of the best features of this TV is the deep shades of black that really make the colors pop.
