Product Snapshot

Overview

Introduced in 2022, the Vizio M-Series Quantum X is a mid-range television in 50, 65, and 75-inch sizes. The size options differ slightly in total brightness output, but their performance is otherwise similar.

The M Series Quantum X or MQX TV stands out as one of the more affordable 4K TVs to offer quantum dot technology, a native 120Hz refresh rate for smoother motion, and HDMI 2.1 ports for gaming enthusiasts.

It’s also one of the earliest TVs to use the WiFi 6E standard, which improves bandwidth for cloud-based gaming. Positioned as a value-oriented mid-range option, the MQX strikes a balance between advanced features and affordability, offering enjoyable picture quality, competitive gaming capabilities, and an intuitive SmartCast interface that works with the most popular streaming apps.

Consensus

our Verdict

The 2022 Vizio M-Series Quantum X TV has a respectable peak brightness of over 800 nits and delivers 18,921:1 contrast in HDR. Inputs include USB, analog video, digital audio, and 2 HDMI 2.1 ports supporting 4K 120Hz signals and variable refresh rate (VRR) compatibility.

The MQX excels with a tested lag time of under 10 ms and a native 120Hz refresh rate, plus WiFi 6E for higher bandwidth wireless streaming. It has a wide color gamut, but viewing angles fall short at 30 degrees.

It shows deep blacks with only a .81% deviation, but gray uniformity is average, with a 4% deviation.

It doesn’t get as bright as mini LED models; reflections can impede the view in bright spaces. The controls are good, but the built-in sound quality is mediocre. Striking a balance between price and performance, the 2022 Vizio M-Series Quantum X TV is excellent.

ReasonS to Buy

  • Above-average 800-nit peak brightness for its price point
  • HDMI 2.1 inputs and Wi-Fi 6E for fast streaming
  • Convenient, easy-to-use remote control
  • Variable refresh rate support with 120Hz native refresh rate

Reason to Avoid

  • Not as bright as some competitors using mini LED technology
  • Just 30 local dimming zones, rather than the 700+ on more expensive LED TVs
  • Narrow viewing angles, with color washout beginning at 30 degrees
  • Mediocre gray uniformity, with a 4% deviation
  • Some blooming in darker scenes

The Vizio M Series Quantum X and Vizio M6 are both budget smart TVs that use Vizio’s SmartCast smart TV interface.

The Quantum X is significantly brighter, peaking at 973 cd/m2. In comparison, the M6 tops out at 252 cd/m2.
