The Vizio M7 Series Quantum 2021 is a good overall TV. It's a mid-range model that replaces the Vizio M7 Series Quantum 2020 and offers much of the same performance and features. It has a basic 60Hz panel, and unlike most 60Hz TVs available in 2021, it has native FreeSync variable refresh rate (VRR) support to reduce screen tearing. It has low input lag and a quick response time for a responsive gaming experience, but like most VA panel TVs, there's some black smearing with fast-moving objects. Speaking of VA panels, it has a fantastic native contrast that displays deep blacks in the dark. It has a full-array local dimming feature, but it's not that good. Its viewing angles are worse than other similar TVs, so it's really not suggested for a wide seating arrangement. The built-in SmartCast system doesn't come with an app store and can feel buggy at times, but you can cast anything you want from your phone using Google Chromecast or Apple AirPlay.
The Vizio MQ7 is good for most uses. It performs best in dark rooms, like for watching movies, because it has a fantastic native contrast ratio for deep blacks. Its FreeSync support, low input lag, and quick response time make it great for gaming. It displays a wide color gamut for HDR content, but it doesn't get very bright in that mode to make highlights stand out. It's decent for watching TV shows and sports, but it has narrow viewing angles if you want to use it in a wide seating area.
The Vizio MQ7 is great for watching movies in a dark room. It has a VA panel with a fantastic native contrast ratio to display deep blacks. Black uniformity is good, and it has a full-array local dimming feature, but it's unremarkable and doesn't improve the picture quality much in dark scenes. The TV removes judder from native 24p sources but not from 60p/i sources.
The Vizio MQ7 is decent for watching TV shows in a bright room. It has decent peak brightness and decent reflection handling if you want to watch it in a room with a few lights. You can cast any show you want from your phone onto the TV. Sadly, there are some upscaling artifacts with 720p content, like from cable boxes. Also, it has narrow viewing angles so the image looks really inaccurate when viewing from the sides.
The Vizio MQ7 is decent for watching sports in well-lit rooms. It has a quick response time, so motion looks smooth for the most part. It's a good choice if you want to use it in a room with some lights around due to its decent reflection handling and peak brightness. Unfortunately, it's not a good choice for watching the big game with a large group of friends as the image looks washed out when viewing from the sides.
The Vizio MQ7 is great for gaming. Even though it's limited to a 60Hz panel, it still has FreeSync VRR support to reduce screen tearing. Input lag is low, and it has a quick response time, but you may notice some black smearing. It's great for dark room gaming because it has fantastic contrast and good black uniformity, but the local dimming feature doesn't improve the contrast all that much.
The Vizio MQ7 is very good for watching HDR movies. It supports both Dolby Vision and HDR10+, so you can watch your favorite HDR content no matter the format it's in. It also displays a really wide color gamut for HDR content. It has a fantastic contrast ratio that displays deep blacks and has good black uniformity, but its local dimming feature is unremarkable. Also, it doesn't get bright enough to make highlights pop.
The Vizio MQ7 is very good for HDR gaming. It provides great gaming performances thanks to the VRR support, quick response time, and low input lag. HDR content looks good because it displays deep blacks and has a wide color gamut. Unfortunately, its full-array local dimming feature doesn't improve the contrast much, and it doesn't get bright enough to make highlights pop.
The Vizio MQ7 is good to use as a PC monitor. It has a quick response time and low input lag for a responsive gaming experience. It's good to use in both dark and fairly well-lit rooms as it has a fantastic contrast ratio and decent peak brightness. It also displays chroma 4:4:4, which helps with text clarity when using it as a PC. Unfortunately, it has very narrow viewing angles, so the image looks washed out at the sides if you sit too close.
The Vizio MQ7 is a mid-range model that replaces the Vizio M7 Series Quantum 2020. It sits alongside the Vizio M6, which doesn't have a local dimming feature, and the stand isn't adjustable. The M7 competes with other entry-to-mid range models like the Hisense U6G, the Samsung Q60/Q60A QLED, and the Sony X85J.
The Vizio M7 has a simple design that should look nice in any setup. It has thin borders on three sides, except the bottom border is thicker. The stand features new flat feet compared to the Vizio M7 Series Quantum 2020, and you can adjust their height.
The stand consists of two feet that are nearly as wide as the TV itself. It can be adjusted in two positions; the bottom position (as seen in the photo above) is about 2 inches off the table, and the higher position raises the screen 3.25 inches off the table, so there's enough room to place a soundbar without blocking the screen.
The stand is advertised to hold any Vizio M Series soundbar in place even when wall-mounted, but we don't test for this.
Footprint of the 55" TV: 38.54" x 4.25".
The Vizio M55Q7 is on the thick side, so it may stick out a bit if you wall-mount it.
The build quality is decent. It's made out of plastic, and there's noticeable flex on the back panel near the inputs and along the bottom bezel. The stand holds the screen well, but it wobbles more in the elevated feet position. We noticed there are two small cracks in the top right and top left corners of the screen. We don't know if it was damaged in transport or if it left the factory like that, so we're not considering it for our build quality score.
The Vizio MQ7 has a fantastic native contrast ratio thanks to its VA panel. It displays deep blacks, and the full-array local dimming feature improves it a bit. The photo above looks different than the photo from the Vizio M7 Series Quantum 2020 because it seems that our unit of the 2021 model has a warm color tone, but this can vary between units.
The SDR brightness is decent. Brightness varies between different content, especially in the 2% window, which is more dim because of the local dimming. It gets bright enough with real content to fight some glare from a few light sources.
We also measured the 2% window using different Active Full Array settings to see how the local dimming affects the brightness. You either need to disable it or set it to 'High' to get the brightest highlights:
We tested SDR brightness after calibration in the 'Calibrated (Dark)' Picture Mode with Gamma set to '2.2', Color Temperature to 'Warm', and Active Full Array on 'High'. If you want the brightest image possible at the cost of image accuracy, we reached 597 nits in the 10% window with the 'Vivid' Picture Mode and everything else at their default settings.
It has an unremarkable local dimming feature, much like the Vizio M7 Series Quantum 2020. There aren't many zones, about 27, and it can go up to 32 zones on the larger sizes. Because of this, zonal transitions are visible with fast-moving objects, which could get distracting. The local dimming dims really small objects, like a star field, to the point where you lose details. There's a bit of blooming around bright objects, but it's very faint. Sometimes it raises the black levels too, which makes blooming less noticeable, like around subtitles. Overall, it's slightly better than the 2020 model, but not by much. We tested it with Active Full Array on 'High'.
The local dimming performs exactly in Game Mode as outside of it. You need to enable Game Low Latency to enter Game Mode and you can use any of the Picture Modes.
The HDR brightness is disappointing, and it doesn't get brighter in HDR compared to SDR. Once again the 2% window is darker than the rest because of the black crush caused by the local dimming feature. We measured the 2% window using the following Active Full Array settings:
Essentially, setting the local dimming to 'Low' really crushes highlights. We measured the brightness in the 'Calibrated (Dark)' Picture Mode with Gamma set to '2.2', Color Temperature on 'Warm', and Active Full Array on 'High'. You can't adjust the Backlight setting in HDR. The EOTF follows the target well using these settings, but some scenes are too bright. If you want, you can get an even brighter image by setting Gamma to '2.2', as seen in this EOTF.
Once again, the Vizio MQ7 has disappointing HDR brightness in Game Mode. It's the same as outside of Game Mode because you don't need to change the Picture Mode. We also measured the 2% window using different Active Full Array settings:
The Vizio MQ7 has decent gray uniformity, but this can vary between units. The edges of the screen are noticeably darker in scenes with uniform colors, and there's visible backlight bleed in dark scenes. There's also a bit of dirty screen effect in the middle, which could get distracting during sports.
The black uniformity is great. Uniformity is better without the local dimming feature enabled, but the screen looks more blue than black. With it enabled, the screen looks black, but there's blooming around the center cross. Keep in mind that uniformity can vary a bit between units.
The Vizio M55Q7 has bad viewing angles. Although we expect this from a VA panel, it's even worse than most TVs. The image looks inaccurate as soon as you move off-center, and the colors even start to appear inverted at really wide angles, almost like a TN panel.
We tested it with the Enhanced Viewing Angle disabled, but we also tested it with the setting enabled to see if it would make any difference. However, enabling it didn't improve the viewing angles much:
The Vizio M7 has decent reflection handling. It's similar to the Vizio M7 Series Quantum 2020, but light is reflected back a bit stronger. It's fine for a room with a couple of lights around, but we suggest it not be placed opposite a window with direct sunlight.
The out-of-the-box accuracy is excellent. It's a significant improvement over the Vizio M7 Series Quantum 2020, but this can vary between units. Most colors and the white balance are only slightly inaccurate, and the color temperature is close to the 6500K target. Gamma is good, but most scenes are brighter than they should be.
After calibration, it has incredible accuracy. White balance and colors are improved even more, and gamma is perfect. The color temperature remains virtually unchanged.

Like other Vizios, the Vizio MQ7 has some trouble upscaling 480p content, like from DVDs. There are some artifacts that aren't visible on other 4k TVs.
This TV upscales 720p content well, like from cable boxes, but once again there are some artifacts.
Fortunately, there aren't any issues upscaling 1080p content. Blu-rays look as good as native 4k content.
The Vizio M7 Quantum uses a BGR sub-pixel structure, which doesn't affect image quality, but it can affect text clarity when using the TV as a PC monitor. You can read more about it here.
The Vizio MQ7 displays an excellent color gamut for HDR content. It's not as good as the Vizio M7 Series Quantum 2020, but the difference isn't noticeable. It has fantastic coverage of the commonly-used DCI P3 color space and good coverage of the wider Rec. 2020.
Thanks to its wide color gamut, the color volume is good. It displays dark and bright colors well but struggles with really bright colors.
The gradient handling is excellent. There's noticeable banding in the darker colors, especially dark green. Setting Contour Smoothing to 'High' helps remove banding in the test pattern and real content, but this comes at the cost of losing fine details.
There are no signs of temporary image retention; however, this can vary between individual units.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
The Vizio M55Q7 has a good response time. There isn't overshoot in any of the transitions, but the slow response time in dark transitions results in some black smearing.
This TV uses Pulse Width Modulation (PWM) to dim its backlight at any Backlight setting of 99 and below. The 480Hz flicker may cause some image duplication, and if you don't like that, set Backlight to its max.
There's a black frame insertion feature to try to clear up motion blur. It creates some image duplication, and there are strange yellow patches in the white letters, which we didn't see with the Vizio M7 Series Quantum 2020, but we don't know what's causing this. Keep in mind that the BFI score is based on the flicker frequency and not the actual performance.
There's no motion interpolation feature.
Due to the fairly quick response time, there's some stutter as frames are held on longer. This can be noticeable with panning shots, and there's no motion interpolation feature to try to reduce it.
The Vizio MQ7 can remove judder from native 24p sources, like native apps or Blu-ray players.
This TV has a basic 60Hz panel with FreeSync variable refresh rate support to reduce screen tearing. Unfortunately, G-SYNC doesn't work at all as there's still screen tearing. We can't confirm if HDMI Forum VRR works because the Xbox Series X supports both FreeSync and HDMI Forum VRR, so we don't know which one is actively working.
The input lag is incredibly low for a responsive gaming experience. You need to make sure you enable Game Low Latency for it to achieve the lowest input lag possible.
This TV displays any 60Hz signal up to 4k, including 1440p if you create a custom resolution from your PC. It displays proper chroma 4:4:4 at any supported resolution as long as you set HDMI Mode to '2.1' and enable Full Color 4:4:4. This helps with text clarity when using it as a PC. It accepts some 120Hz signals, but it either skips frames or causes the screen to black out.
Since the TV is limited to a 60Hz panel, it only supports games up to 60fps from either the PS5 or Xbox Series X. It has Auto Low Latency Mode that automatically switches the TV into Game Mode when you play a game from a compatible device. Set Game Low Latency to 'Auto' or 'On' for it to work.
Even though it's advertised to have HDMI 2.1 inputs, they're in fact HDMI 2.0. None of the ports can support 4k content up to 120Hz, which means they don't have HDMI 2.1 bandwidth.
The Vizio M55Q7 supports eARC, so it can pass high-quality, uncompressed audio to a compatible receiver through the HDMI 1 port. It can pass Dolby Digital and DTS formats via eARC and ARC, but our unit has issues with the optical connection. It feels like the cable doesn't connect to the input properly, so our unit can't pass audio over an optical connection. We don't know if this is a common issue, so let us know if you experience the same thing.
The frequency response is decent, and it's a nice improvement from the Vizio M7 Series Quantum 2020. It gets loud and has a well-balanced sound profile, so dialogue sounds clear. It produces better bass than the 2020 model, but you still need a dedicated subwoofer if you want a real punchy bass.
The distortion handling is also decent. There isn't too much at moderate listening levels, but it can be more noticeable at its max volume. However, this depends on the content and not everyone may hear it.
The Vizio Smartcast system remains basically unchanged from the past version. It's a decent OS and is easy to use, but navigation isn't the smoothest. Vizio TVs can experience bugs and issues, like:
If you experience any of these issues or different problems, let us know and we'll update the review.
There are banners with suggested content in the home page. There's a setting to disable ads, but we didn't notice any during testing.
The SmartCast system doesn't come with an app store, so you're limited to the pre-installed apps. However, you can cast anything you want from your phone. It's advertised as having Apple AirPlay 2 and Google Chromecast built-in, but only the Chromecast was on the home page; we don't test to see if Apple AirPlay works properly.
Vizio redesigned their remote for 2021, and it now includes a built-in mic for voice control. You can ask it to open apps, ask for the weather, and change inputs, but that only worked after a few tries. Sadly, it can't search for specific content in apps, and you can't ask it to change settings.
There's a single button on the bottom left side to turn the TV On/Off and change inputs.
We tested the 55 inch Vizio M7 Series (M55Q7), and for the most part, we expect our results to be valid for the 50 inch (M50Q7), 70 inch (M70Q7), and 75 inch (M75Q7) models too. It's advertised to also be available in 58 and 65 inch models, but they're not available at the time of writing. We'll update the review when they're available for purchase.
The 2021 models follow a similar naming structure to the Vizio M7 Series Quantum 2020. The way to tell them apart is that the 2020 model codes have H in the suffix, while the 2021 models use J.
|58"||M58Q7-J01||300x200||To be released|
|65"||M65Q7-J01||400x200||To be released|
If someone comes across a different type of panel or their Vizio MQ7 doesn't correspond to our review, let us know, and we'll update the review. Note that some tests, like gray uniformity, can vary between individual units.
You can see our unit's label here.
The Vizio M7 is a good mid-range TV. It offers great gaming features and performs well in both dark and fairly bright rooms. It's a bit on the expensive side compared to other budget-friendly models, and you can get options that get much brighter for a bit more, like the Hisense U8G.
The Hisense U6G is better overall than the Vizio M7 Series Quantum 2021. The Hisense is a much better choice to use in well-lit rooms because it gets much brighter and has superior reflection handling. The Hisense also has a better local dimming feature, but the Vizio displays deeper blacks because it has higher native contrast. Motion looks smoother on the Hisense thanks to the quicker response time, but the Vizio has more gaming features like VRR support.
The LG C1 OLED and the Vizio M7 Series Quantum 2021 are different types of TVs. The LG has an OLED panel with a near-infinite contrast ratio, perfect black uniformity, and wide viewing angles. The LG also has more gaming features like HDMI 2.1 inputs and a 120Hz panel, allowing you to game in 4k up to 120fps, and it has a near-instantaneous response time. On the other hand, the Vizio has much better out-of-the-box accuracy, but this can vary between units. It's also an LED panel that doesn't have the burn-in risk associated with OLEDs.
The Vizio M7 Series Quantum 2021 replaces the Vizio M7 Series Quantum 2020, and both TVs are very similar. Local dimming is a bit improved on the 2021 model as there's less blooming, but the local dimming is unremarkable on each. The 2021 model also comes with a remote with voice control, which the 2020 version doesn't have. The 2020 has a slightly quicker response time, and there's less noticeable black smearing with dark objects. Overall, there aren't any major differences, and it's not worth upgrading to the 2021 model if you already have the 2020 one.
The Vizio M7 Series Quantum 2021 and the TCL 5 Series/S535 2020 QLED are both good 4k TVs. They have the same panel type with similar picture quality as they each have a high contrast ratio, but the full-array local dimming feature is better on the Vizio. The Vizio gets much brighter and has better reflection handling, making it a better choice for well-lit rooms. Also, the Vizio has VRR support, which the TCL doesn't have. However, the TCL doesn't have any trouble upscaling lower-resolution content like the Vizio, and the built-in Roku smart platform is better overall than the Vizio SmartCast system.
The Hisense U8G is significantly better than the Vizio M7 Series Quantum 2021. The Hisense is a high-end model with a 120Hz panel and HDMI 2.1 inputs, while the Vizio is a lower-end option with a 60Hz panel and HDMI 2.1 inputs. The Hisense is better in several ways, including the improved local dimming, higher peak brightness in SDR or HDR, and better reflection handling. The Hisense has a quicker response time, so motion looks smoother, and it has other features like motion interpolation and the ability to remove judder from 60p/i sources.
The Vizio M7 Series Quantum 2021 is better overall than the Samsung AU8000. The Vizio has more features like a full-array local dimming feature, which improves the contrast ratio, but it causes blooming around bright objects. The Vizio also has FreeSync support, which the Samsung doesn't, and it has a quicker response time. The Vizio displays a much wider color gamut for HDR content, but neither get bright enough to make highlights pop. The Samsung doesn't have trouble upscaling lower-resolution content like the Vizio, and the Tizen OS has a built-in app store, which Vizio's SmartCast OS doesn't.
The Vizio P Series Quantum 2020 is better than the Vizio M7 Series Quantum 2021 mainly because the P Series is a higher-end TV. The P Series has a 120Hz panel while the M7 is limited to a 60Hz panel, but each have VRR support. HDR content looks better on the P Series because it gets brighter and has better local dimming. The P Series has a quicker response time, but you may notice more image duplication because its backlight flickers at 120Hz, while the M7 flickers at 480Hz.
