The Vizio M Series Quantum 2019 is an impressive 4k TV with a great picture quality. It uses a VA panel and has outstanding contrast ratio, exceptional black uniformity, and an excellent color gamut. The full array local dimming performs surprisingly well, and HDR content looks decent, though it's limited by the TV's peak brightness. Motion handling is good, and there's an optional black frame insertion feature to further reduce blur. Unfortunately, there are some issues with uniformity, and like most VA panels, the viewing angles are poor. Nonetheless, it's an all-around great TV that performs well for most uses.

Our Verdict

7.9 Mixed Usage

The Vizio M Series Quantum 2019 is a great TV for mixed usage. It delivers an impressive picture quality that's suitable for any type of content and performs well in both bright and dark rooms. Unfortunately, the viewing angles make it less ideal for those with a wide seating arrangement, but its overall performance should satisfy most people. Additionally, it has an exceptionally low input lag for those who want to game or use it as a PC monitor.

Pros
  • Deep, uniform blacks.
  • Impressive color gamut.
  • Excellent low input lag.
Cons
  • Mediocre dirty screen effect (DSE).
8.5 Movies

The Vizio M Series Quantum 2019 is a great TV for watching movies. With its full array local dimming feature and outstanding contrast ratio, this TV can produce deep inky blacks, which is great for watching movies in a dark room setting. It also has good upscaling performance for lower resolution content and remarkable motion handling to keep the picture crisp during fast-moving scenes.

7.4 TV Shows

The Vizio M Series Quantum 2019 is good for watching TV shows in a bright living room. It has great reflection handling and great peak brightness with SDR content, so glare shouldn't be an issue. Unfortunately, the image degrades at an angle, and older, lower resolution shows aren't upscaled as well as on other TVs.

7.5 Sports

The Vizio M Series Quantum 2019 is a good TV for watching sports, as it has outstanding motion handling that keeps the picture clear during fast-paced moments. However, the TV has some dirty screen effect that may be distracting for some, and the narrow viewing angles make it less ideal for watching with a group of friends.

7.9 Video Games

The Vizio M Series Quantum 2019 is an excellent TV for gaming. Although the refresh rate is limited to 60Hz, it has a remarkably low input lag and outstanding motion handling. Unfortunately, it doesn't support FreeSync variable refresh rate and doesn't have an 'Auto Low Latency' mode. However, the exceptional black uniformity of this TV makes it a great choice for dark room gaming.

8.3 HDR Movies

The Vizio M Series Quantum 2019 is a great TV for watching movies in HDR. It has an impressive contrast ratio and good local dimming feature. This TV also has an impressive color gamut. Unfortunately, it only has decent peak brightness in HDR.

7.9 HDR Gaming

The Vizio M Series Quantum 2019 is an excellent TV for HDR gaming. It has outstanding low input lag and an excellent response time, for a responsive gaming experience. It also looks amazing in a dark room, due to the impressive contrast ratio, outstanding black uniformity, and good local dimming feature. This TV also has an impressive color gamut, but only decent peak brightness in HDR, although most games have an option to adjust the game to match the TV's peak brightness.

7.5 PC Monitor

The M Series Quantum 2019 is a great TV for use as a PC monitor. It has outstanding low input lag for a responsive desktop experience, and it has an excellent response time, so there's very little blur behind fast-moving objects. This TV can also display proper chroma 4:4:4 in any of the supported modes. Unfortunately, the image degrades at an angle.

Market Context

The Vizio M Series Quantum is a mid-range 4k Vizio TV, and it directly replaces the Vizio M Series 2018. It's available in three variants: the M7 variant, the M8 variant, and a Black Friday variant known as the M6. The M Series Quantum's main competitors are the Samsung RU8000, Sony X850F, and LG SM8600.

Design

Design
Style
Curved No

The Vizio M Series Quantum 2019's design is ordinary. It has a clean, minimalist design with wide-set feet, but overall, it's fairly plain.

Design
Stand

The feet are wide and require a table nearly the full width of the TV, which isn't ideal, especially for the larger sizes.

Footprint of the 65" stand: 50.6" x 11.7"

Design
Back
Wall Mount VESA 400x200

The back of the TV is a mix of metal and hard plastic, and the inputs are located on the left along with the TV's controls. The inputs are easy to access, even when the TV is wall-mounted.

Unfortunately, there's no cable management.

Design
Borders
Borders 0.51" (1.3 cm)

The borders are fairly thin and shouldn't be distracting.

Thickness
Max Thickness 2.87" (7.3 cm)

The M series Quantum is reasonably thin, but slightly thicker than last year's model.

Design
Build Quality

The Vizio M Series Quantum has a decent build quality. It's mostly made out of hard plastic and the stand supports the TV well, though there's a bit of wobble to it. Our unit has a slight tilt backwards, but we're not sure if this is by design or a defect.

The M Series Quantum has an outstanding native contrast ratio, similar to the Vizio V Series 2019. This results in excellent deep blacks, great for dark-room viewing. With local dimming enabled, the contrast ratio is boosted significantly, similar to the Samsung Q70/Q70R QLED.

7.5
Picture Quality
Local Dimming
Local Dimming
Yes
Backlight
Full-Array

The local dimming feature on the M Series is good. It can struggle a bit with fast-moving objects, as the backlight tries to keep up from zone to zone, causing the object's leading edge to look dimmer. Smaller objects can also appear dimmer, but blooming is kept to a minimum and you shouldn't notice significant brightness change when using subtitles.

Higher settings on the TV cause the TV's overall brightness to increase. Although we normally recommend the 'Medium' setting, it might be too bright for some environments, in which case the 'Low' setting might be better.

The M7 Series Quantum 2019 variants have a slightly worse local dimming feature, with fewer dimming zones.

The Vizio M658-G1 has great peak brightness, but it isn't quite as bright as the M Series 2018. There's some variation in brightness with different content (ABL), but it shouldn't cause any issues for most people.

We measured the peak brightness after calibration, with the 'Calibrated Dark' Picture Mode, and the Color Temperature set to 'Normal'.

The local dimming feature affects the TV's peak brightness, and higher settings result in a higher peak brightness. We measured the peak brightness with the Active Full Array setting on 'Medium'. Lower settings result in a lower peak brightness, so you may need to adjust this setting depending on your viewing conditions. The 'High' setting resulted in a dimmer image with some real content.

If you prefer a brighter image, or a colder color temperature over an accurate one, with the 'Vivid' Picture Mode and the 'Cool' Color Temperature, we measured a peak brightness of 634 cd/m² for a short period of time, as measured on the 10% test window.

The M7 Series Quantum 2019 variants have a slightly lower peak brightness.

Decent peak HDR brightness, slightly worse than last year's models.

We tested the HDR peak brightness with no calibration settings, using the 'Calibrated Dark' Picture Mode, with the Backlight set to '50'.

The local dimming feature affects the TV's peak brightness, and higher settings result in a higher peak brightness. We measured the peak brightness with the Active Full Array setting on 'Medium'. Lower settings result in a lower peak brightness, so you may need to adjust this setting depending on your viewing conditions. The 'High' setting resulted in a dimmer image with some real content.

If accuracy isn't as important to you, or if you prefer a colder color temperature, the 'Vivid' Picture Mode hit a peak brightness of 581 cd/m² for a short period of time, with the Backlight set to '100', Color Temperature set to 'cool', and local dimming on 'High'.

The M7 Series Quantum 2019 variants have a slightly lower peak brightness.

The Vizio M Series Quantum 2019 has an impressive color gamut, one of the widest we've ever measured.

The EOTF doesn't follow the PQ Curve very well. Darker scenes are displayed accurately, but it starts tone mapping very early, and all scenes above around 100 cd/m² appear darker than they should be. In 'Game' mode, the backlight defaults to '100', which causes the EOTF to display darker scenes brighter than they should be, as shown by this EOTF. With the backlight set to '50', the EOTF more closely tracks the PQ curve.

If you find HDR too dim, changing the Backlight to '100' results in a brighter image, as shown by this EOTF. If you want an even brighter image, decreasing the gamma will probably improve the brightness a bit more, but we don't expect it to impact the apparent brightness as much as the backlight setting.

The M Series Quantum 2019 uses PWM to dim its backlight, and there's flicker at all backlight levels below 100. The 480Hz flicker is identical to last year's M Series 2018, but behaves very differently from the 120Hz flicker on the Vizio P Series Quantum X 2019. This high flicker frequency does cause noticeable duplications in motion, which can be seen in our response time photo.
