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.

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
