Vizio supports both major HDR formats, HDR10 and Dolby Vision, in the M-Series. Unlike the M7 from 2021, the MQX has a true 120Hz refresh rate, which allows compatibility with 4K/120Hz signals from game consoles like the Xbox Series X and PlayStation 5, and worked well in our tests. The MQX has fewer dimming zones than more expensive TVs like the TCL 6-Series and Hisense U8H, but it offers 16 zones on the 50-inch, 30 on the 65-inch and 42 on the 75-inch, which is more than enough for excellent overall picture quality, with bright highlights, dark black levels, punchy contrast and accurate color. The Vizio MQX is one of the least expensive TVs to feature full-array local dimming, which lets it reproduce TV shows, movies and games with enough contrast and pop to do HDR justice. The prices shown below are for the 65-inch size. The R648 series has 8K resolution and is significantly more expensive. The R646 series uses the Google TV operating system but otherwise has similar specifications to the R655 models reviewed here. Note that in addition to the R635, which this TV replaces, other versions of the 6-Series were released earlier and remain on sale. And, finally, its Roku TV operating system is our hands-down favorite. It improves upon the previous R635 series with new gaming extras and a center-mount stand that you can elevate to make room for a soundbar, although the new 85-inch size has standard legs. This TV has an excellent image thanks to mini-LED tech and well-implemented full-array local dimming that helps it run circles around just about any other TV at this price. For the last five years, the TCL 6-Series has been our favorite TV for the money, and the latest version - also known as the R655 series - is no exception.
