The Vizio M7 Series Quantum 2019 (M437 / M507 / M557 / M657) is a great 4k TV with good picture quality. It delivers deep uniform blacks in a dark room and has an exceptional color gamut, great gradient handling, and decent HDR peak brightness. It has a fast response time that leaves a little longer blur trail behind fast-moving content but, on the upside, it creates very little stutter in movies. There's no motion interpolation feature and the TV uses PWM to dim its backlight. The M7 has a very low input lag which is great for gaming but unfortunately, like most TVs with VA panels, the image loses accuracy when viewed from the side and it has noticeable uniformity issues in darker scenes.

Our Verdict

7.7 Mixed Usage

The M7 Series Quantum 2019 is a great TV for mixed use. It can get fairly bright for an average-lit room and can display deep blacks, which is great for watching movies when in a dark room. Unfortunately, the viewing angles are disappointing and do not favor watching TV from the side, but the TV has an excellent wide color gamut for HDR content and a very low input lag that offers a great gaming experience.

  • Excellent low input lag.
  • Great color accuracy.
  • Excellent color gamut.
  • Image degrades at an angle.
  • Local dimming performance is just decent.
8.2 Movies

This a good TV for watching movies. It displays deep, uniform blacks in a dark room thanks to the high native contrast ratio and decent local dimming support. 1080p content looks almost as good as 4k. The TV displays little stutter in movies and can remove 24p judder from most sources. It has a great pre-calibration color accuracy but unfortunately, there's no motion interpolation feature to please the soap opera effect fans.

7.3 TV Shows

This is a good TV for watching TV shows. It gets bright enough and can handle reflections well, so it's suitable for most rooms. Unfortunately, this TV has disappointing viewing angles so it's not a good choice if you like to move around while watching your favorite TV show. Also, Vizio's upscaling of lower resolution content is slightly worse than most brands. Finally, its smart interface has a good selection of apps, but you can't add any new ones in case your favorite show moves to a new app.

7.3 Sports

The M7 Series is a good TV for watching sports. It can get bright enough for most rooms and can handle the reflections of a few extra lights well. Unfortunately, the viewing angles are disappointing and don't favor watching the big game with a group of friends. Also, some demanding sports fans might be disappointed by the amount of dirty screen effect this TV has on darker scenes.

7.6 Video Games

The M657-G0 is an excellent TV for playing video games. It has a remarkably low input lag and a fast response time that delivers responsive gaming experiences with crisp motion. It displays 1080p and 4k resolution well but unfortunately, there are no advanced gaming features like a variable refresh rate or an auto low latency feature like the higher-end models have.

7.9 HDR Movies

This is a great TV for watching HDR movies. It has a high native contrast ratio, impressive black uniformity, and decent local dimming. It can display deep uniform blacks in a dark room that enhances your HDR movie watching experience. It has a wide color gamut and displays rich, saturated colors but its HDR peak brightness is not always enough to display the latest HDR content with bright highlights as its creator intended it to be.

7.6 HDR Gaming

This TV is excellent for playing HDR video games. It has a fast response time and displays fast-moving content with little blur. When in HDR, the TV has a very low input lag and delivers vivid HDR content with rich, saturated colors thanks to its excellent wide color gamut. In a dark room, where HDR is meant to be watched, blacks are deep and HDR peak brightness is good enough for most HDR games.

7.4 PC Monitor

This is an impressive TV for use as a PC monitor. It has a very low input lag and feels very responsive. It has a fast response time and displays a fast-moving mouse with just a little blur trail. It has a VA panel and is immune to the burn-in risk and can display chroma 4:4:4 properly so text looks clear. Unfortunately, the image isn't accurate at the sides if you sit up close due to the disappointing viewing angles.

The Vizio M7 Series Quantum is a mid-range 4k Vizio TV, and along with the Vizio M Series Quantum 2019 replaces the Vizio M Series 2018. There's also a Black Friday variant known as the M6. The M7 Series Quantum's main competitors are the Samsung RU8000, Hisense H9F, and the TCL 6 Series R625 2019.

Curved No

The Vizio M7 Series Quantum's design is decent and resembles the other Vizio M Series Quantum 2019. It has a small stand that supports the TV well but can't prevent all wobble. The borders are thin and not distracting, while the overall build quality is decent.


The stand is minimalist and can't prevent wobbling. It's very wide and requires a large table.

Footprint of the 65" stand: 50.6" x 10.9"

Wall Mount VESA 400x200

The back of the TV is almost identical to the Vizio M Series Quantum 2019. Most inputs are facing sideways which is great if you wall-mount the TV, but unfortunately, there's no provision for cable management.

Borders 0.51" (1.3 cm)

The borders of the M657 are thin and won't distract your viewing experience.

Max Thickness 2.87" (7.3 cm)

The TV is relatively thin and won't stick out much if you wall-mount it.

Build Quality

The build quality of the M7 Series Quantum is decent. It resembles last year's M Series a lot. There are no gaps or loose ends and we had no issues with our TV during testing.

Unfortunately, a power outage that happened after we finished testing must have affected the TV, as we can no longer turn it on.

The M657 we tested has an excellent contrast ratio and the TV can deliver very deep blacks when in a dark room. Local dimming helps improve performance but not significantly.

Picture Quality
Local Dimming
Local Dimming

The local dimming of the M7 Series Quantum is decent. This is one of the most critical differences between this variant and the M Series Quantum 2019. The M7 has a smaller number of zones and this creates visible blooming in dark scenes when in a dark room. This is especially noticeable when displaying subtitles. There are only two vertical local dimming zones and most subtitles span both. When subtitles are displayed, there's a horizontal blooming strip from one edge of the screen to the other. If you can watch movies without them you're better off.

We recommend you set local dimming to 'High' as it gives you the best results.

The Vizio M657-G0 has good peak brightness, but not as good as the M658-G1. Brightness varies a little depending on content but it's not very noticeable, and the TV is more suitable for an average-lit room.

We measured the peak brightness after calibration, with the 'Calibrated Dark' Picture Mode, Local Dimming set to 'High', backlight set to 'Max', and Gamma set to '2.1'. These were also the settings that produced the brightest image.

The peak HDR brightness of the M657-G0 is mediocre, worse than last year's M Series 2018, and just slightly worse than the M8 (M Series Quantum 2019) variant. Depending on the scene, the TV might not always deliver very bright HDR highlights as it should.

We tested the HDR peak brightness with no calibration settings, using the 'Calibrated Dark' Picture Mode, with the Local Dimming set to 'High' and Gamma set to '2.1'.

For those who don't care for accuracy, we were able to reach 485 cd/m² on the 10% window, in the 'Vivid' Picture Mode with Backlight set to '100', Color Temperature set to 'Cool', Gamma set to '2.1', and Local dimming on 'High'.

The M657 has decent gray uniformity both in darker and brighter scenes. With our unit, the darker scenes have slightly more noticeable dirty screen effect, but this is panel-specific and might not be the case with yours.

The viewing angles of the M657 are disappointing. The image degrades quickly as you move off-center, making the TV not a good choice for wide seating arrangements. If you want a TV with wide viewing angles, check out the LG UM7300.

The pre-calibration accuracy of the M657-G0 is impressive. Most colors and gray inaccuracies won't be noticeable to the untrained eye. However, the gamma doesn't follow the curve very well and most scenes are darker than they should be.

Excellent accuracy for the M657-G0 after calibration. We changed the Gamma setting to 2.1 and now Gamma follows the target very closely except for the very dark scenes that are still crushed. Any remaining inaccuracies in the colors and the grays are unnoticeable and the color temperature is very close to the 6500 K target.

Picture Quality
480p Input

The M7 has the same upscaling issues as all recent Vizio TVs we've tested. 480p content, like DVDs, isn't upscaled as well as most TVs. Although this might not bother you, it's noticeable.

720p Input

720p content, like from cable boxes, looks a bit worse than most other brands. It still looks decent, though, and should be okay for most people.

The Vizio M7 Series Quantum 2019 has an excellent color gamut, among the widest we've ever measured. Unfortunately, the EOTF (Electro-Optical Transfer Function) doesn't follow the PQ curve closely. Although darker scenes are displayed fairly accurate (just slightly brighter), the roll-off towards the TV's highest brightness starts too early and all scenes above around 100 cd/m² appear darker than they should be. The 'Game' mode EOTF is rather similar in behavior as shown here, but the darker scenes are slightly brighter as the backlight defaults to '100'.

If you find HDR too dim, check in the settings page how to make HDR brighter.

The M657 has impressive gradient handling. Most colors have some noticeable banding, but nothing serious. Unfortunately, if banding bothers you, there's no feature to help improve it.

The M657 has an impressive response time. Even though it's slightly slower than the M658-G1, fast-moving content is crisp with little blur trail. There are a few duplications in motion, as seen in the above photo, due to the backlight flicker.

PWM Dimming Frequency
480 Hz

The M657 uses PWM to dim its backlight. The flicker frequency is at 480Hz, identical to the M658-G1. There are some duplications in motion as you can see in the response time photo but shouldn't be an issue for most people.

The M657 has an optional black frame insertion (BFI) feature to help improve the appearance of motion. It can lower its flicker frequency to 60Hz, which makes motion appear crisper but at the same time, there are more noticeable duplications in motion. The setting that controls BFI is called Clear Action.

Motion Interpolation

Thanks to the not-so-fast response time, the M657 has only little stutter in movies or other 24p content. However, in slow panning shots, some stutter is noticeable.

The M657-G0 can remove judder from 24p sources and from the native apps, provided you enable the Film Mode. However, 24p judder sent through a 60p/i source, like a cable box, can't be removed by the TV.
