The Vizio M Series 2018 is a good 4k TV for a wide range of usages. It has a high native contrast ratio so blacks appear deep in a dark room, but unfortunately, the local dimming doesn't work well to improve them further. It can also get bright to overcome glare but can't produce bright or saturated HDR highlights. Motion handling is also decent, but the image degrades when viewed at an angle. Unlike last year's Vizio M Series, the 2018 model includes a TV tuner.

Design
The design of the Vizio M Series 2018 is good. It has a sleek look and feels sturdy. The new stand and the thin metallic borders give it a more premium look. It still lacks any planning for cable management, but the good news is that the inputs are very close to the side.
This year's Vizio M-series comes with a sleek and sturdy looking stand. This is quite an aesthetic change from the wire-like stand used in the M-Series 2017.
Footprint of the 55" TV stand: 50.7" x 10.9"
The back of the TV is plastic. It has been redesigned and has a more sleek look and although the inputs have changed sides, they are still split between the bottom and the side edge. There is no planning for cable management.
The Vizio M Series 2018 has a very uniform and relatively cool temperature footprint.

The picture quality of the Vizio M Series 2018 is good. It has an excellent contrast ratio that allows it to achieve deep blacks in dark scenes and the color accuracy is remarkable but it does not have a wide color gamut. The brightness levels are good and enough to overcome glare making it suitable for brighter rooms, but viewing angles are somewhat limited. Sports fans should know that some dirty screen effect is to be expected.
The contrast ratio of the Vizio M 2018 Series is very good but slightly worse than last years' model. Dark scenes produce nice blacks even in low-light environments.
The contrast ratio does not improve with local dimming enabled.
The Vizio M Series 2018 has a sub-standard Local Dimming. Clouding can be seen around moving objects and this might be more apparent when subtitled content is viewed.
The best results are obtained when local dimming(called Xtreme Black Engine Plus on this Vizio TV) is set to medium.

The SDR peak brightness of the Vizio M Series 2018 is very good. The TV reaches and maintains high brightness levels at most window sizes.
The testing was done with local dimming(called Xtreme Black Engine Plus on this Vizio TV) set to medium.

The HDR peak brightness of the Vizio M Series 2018 is okay. It is very similar to last year's model.
The TV displays small bright details well in dark HDR scenes but fails to reach the 1000 nits HDR content is targeting.

The gray uniformity of the Vizio M Series 65 is okay. At the 50% gray level, clouding is fairly noticeable in the center of the screen. Some dirty screen effect is visible during panning shots and sports viewing.
Results improve significantly at darker gray levels, where it gets hard to notice clouding.
- 20% Color Shift
- 40% Brightness
- 40% Black Level
The viewing angle is poor. Colors shift quickly and black washes out as soon as one moves away from the center, but the brightness stays at acceptable levels for bigger angles.
- 75% Native Std. Dev.
- 25% Std. Dev. w/ L.D.
The black uniformity of the Vizio M Series 2018 is remarkable. There is some slight clouding to the right, but in general, the screen is very uniform.
With local dimming turned on, the uniformity is a little worse, as some blooming is obvious around the middle white cross while the rest of the screen remains mostly black.
The Vizio M Series 2018 handles reflections very well. In bright environments, the TV is able to overcome glare. However, it cannot handle direct reflections with the same efficiency due to the lack of an anti-reflective coating.
- 45% White Balance dE
- 45% Color dE
- 9% Color Temperature
The Vizio M65-F has impressive color accuracy. When the picture mode is set to Calibrated Dark, both the white balance dE and the color dE are below 3, most people will not notice any imperfections.
The gamma is at 2.08 and fairly consistently below our target of 2.2. This makes shadows look darker, but again it will pass unnoticed by most people.
- 45% White Balance dE
- 45% Color dE
- 9% Color Temperature
Colors and shadows of the Vizio M65-F0 after calibration are amazing. The already great accuracy becomes almost perfect in all aspects of our measurements. color dE and white balance dE are very small, whereas the gamma curve is followed perfectly at 2.2. Finally, the color temperature is spot on at 6500K
Note: Calibration can be performed very easily with the help of the 'Smartcast' app, as no on-screen menu is necessary.
You can see our recommended settings here.
Upscaling of low-quality content such as DVDs is a bit more blocky than other TVs and there is more noise, similar to the Vizio M Series 2017. This is visible when viewing DVDs.

- 25% DCI P3 uv
- 25% Rec 2020 xy
- 25% Rec 2020 uv
The color gamut is okay for the Vizio M65-F0. It fails to cover either of the color spaces measured adequately and certainly falls below the threshold to be classified as having a wide color gamut.
In the Calibrated Dark picture mode, the HDR EOTF follows the target PQ curve fairly well, but with a bit of over-brightening in dark shades and an early roll-off of bright shades. The EOTFs in Calibrated Dark with Game Low Latency enabled and in the Computer picture mode are very similar to that of Calibrated Dark.
Mediocre color volume. The narrow color gamut prevents the TV from achieving a satisfying color volume. It has difficulty displaying deep, dark colors and does not cover either color space very well, although in the Rec.2020 it performs slightly better than the 2017 model.
- 25% Red (Std. Dev.)
- 25% Green (Std. Dev.)
- 25% Blue (Std. Dev.)
- 25% Gray (Std. Dev.)
The gradient performance is very good for this Vizio M Series 2018. It can display our gradient test image almost perfectly, with only small visible imperfections in dark green bands.
The TV has a Reduce Noise feature that may help reduce banding when banding is present in the content itself with the possible trade-off of some loss of fine detail. The Reduce Noise option, however, can not improve any banding that is added to the content, by the TV itself.
No image retention is present on the Vizio M65-F0. This is in line with TVs that use VA panels.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
Motion
- 53% Response Time
- 11% Flicker-Free
- 4% Black Frame Insertion (BFI)
- 5% Motion Interpolation
- 12% Stutter
- 11% 24p Judder
- 5% Variable Refresh Rate
The Vizio 2018 M-Series has decent motion handling. The response time is excellent and there is very little motion blur. The backlight uses PWM to dim and there is some flicker but it is at a high frequency and shouldn't be noticeable to most people. The backlight can reduce the flicker frequency to help motion appear more fluid, and unlike most TVs, there is very little decrease in brightness. It does not support any motion interpolation.
- 50% 80% Response Time
- 50% 100% Response Time
The 2018 M-Series has an excellent fast response time. There is very little motion trail behind fast moving objects, most of the blur in the photo is due to persistence. There is a tiny bit of overshoot in some transitions, but these are too minor to cause any overshoot artifacts.
There is some dark haloing visible around the logo. This is likely due to the down transitions being much faster than the up transitions. In this case, the the blue and green pixels of the background go dark before the red pixels in the logo can turn on. This is noticeable in most of the motion blur photos, but is especially noticeable on this TV.
There is backlight flicker at all backlight settings below 100. The flicker frequency is very high at 480 Hz, and most people won't notice it. At low backlight settings there is some decrease in amplitude as well as duty cycle. The backlight is identical to last year's M-Series.
The backlight of the Vizio M 2018 is much better than TVs with lower flicker frequencies like the LG SK9000, and very similar to the TCL R617.
The BFI mode on the M-Series 2018 is activated by setting Clear Action to On. Unlike most TVs, when BFI is enabled the perceived screen brightness is not reduced, as the brightness spikes higher than before to compensate for the off cycles. With BFI enabled the backlight can only flicker at 60 Hz.
The Vizio M65-F0 does not have a motion interpolation feature unlike most TVs we have reviewed.
There is some 24p stutter that is especially noticeable with wide panning shots. Unlike many other TVs, this cannot be reduced by enabling motion interpolation, as the M-Series does not have this feature.
Similar to the 2017 M-Series, the 2018 Vizio M65-F0 can play 24p content without judder, but only when played from a native 24p source like a Blu-ray player or from the native apps. To remove judder set Film mode to on

The Vizio M-Series 2018 does not support any of the variable refresh rate technologies, including AMD's Freesync 2.
Inputs
The Vizio M Series 2018 can play almost any content including HDR. It has excellent low input lag both for SDR and HDR content and it is definitely an improvement with regards to inputs from last years model. Appart from the input lag that has almost halved, the TV supports 4k @ 60 Hz @ 4:2:2 or 4:4:4 color on all ports, as long as you set it to 'Full UHD Color'. This year's M-Series also has a tuner, unlike the previous two years' models.
- 35% 1080p @ 60Hz
- 3% 1080p @ 60Hz + HDR
- 37% 4k @ 60Hz
- 19% 4k @ 60Hz + HDR
- 3% 4k @ 60Hz @ 4:4:4
- 3% 4k @ 60Hz @ 4:4:4 + 8 bit HDR
The input lag is superb and almost half of last year's model. To achieve low input lag you must set the 'Game Low Latency' to on as its is the only setting that matters for input lag. All picture modes can have low input lag, however only the 'Computer' mode can show proper 4:4:4 color.
Aside: The TV treated the Leo Bodnar tool differently than the Leo Bodnar + HDFury chain, in a similar way as last year's M Series 2017, but on the M Series 2018 the input lag didn't change as a result. See the Additional Review Notes for more detail.
- 17% 1080p @ 60Hz @ 4:4:4
- 17% 1080p @ 120Hz
- 17% 1440p @ 60Hz
- 17% 4k @ 30Hz @ 4:4:4
- 17% 4k @ 60Hz
- 17% 4k @ 60Hz @ 4:4:4
Most common resolutions are supported at 60Hz except 1440p. However, this TV does not support 120 Hz.
Only in 'Computer' picture mode can 4:4:4 color be displayed properly. This years' model can support 4k @ 60 Hz @ 4:2:2 or 4:4:4 color on all ports, but it works only when 'Full UHD Color' is enabled for that port.
4k @ 60Hz @ 4:4:4 + HDR is also supported.
The inputs on the side include sockets for Component input which is rare for a TV.
The rear inputs include an 'analog audio out' so you can use wireless headphones with no need for adaptors. Also, a 'Cable/Antenna' input is present to accommodate the TV tuner that is included in this year's model.
Sound Quality
- 75% Frequency Response
- 25% Distortion
The sound quality of the Vizio M Series 2018 is ordinary. This TV gets decently loud, but it may not be loud enough for large and noisy environments. It also lacks a lot of bass and doesn't produce much thump or punch. However, it produces clear dialogs and has relatively low distortion. For a better sound, dedicated speakers or a soundbar is recommended.
- 30% Low-Frequency Extension
- 5% Std. Dev. @ 70
- 20% Std. Dev. @ 80
- 15% Std. Dev. @ Max
- 20% Max
- 10% Dynamic Range Compression
The frequency response is mediocre. Low-frequency extension (LFE) is at 107Hz, which means this TV doesn't produce a lot of thump or punch in the bass range. The response above the TV's LFE point is good, suggesting clear dialog reproduction. However, there is significant pumping and compression at louder volumes, and since this TV doesn't have a room correction system, it wasn't able to remove the modes of our test room around 200Hz. Additionally, this TV gets decently loud, but it may not be loud enough for large and noisy environments,
- 40% Weighted THD @ 80
- 25% Weighted THD @ Max
- 10% IMD @ 80
- 25% IMD @ Max
The distortion performance of the Vizio M65-F0 is decent. The overall amount of THD produced is within decent limits at 80dB SPL, and there is not a big jump in THD at maximum volume either. However, this TV doesn't get very loud.
Smart Features
- 42% Interface
- 2% Ad-Free
- 37% Apps and Features
- 16% Remote
- 3% Remote App
The Vizio M Series 65 uses the Vizio SmartCast smart interface. The selection of smart features is very basic, the main attraction is the built-in Chromecast media streaming device, which allows you to stream files from just about anything. There is a small selection of built-in apps that cover the basics, but there is no app store and no way to add additional functionality.
The interface is very basic, there are no animations, just an animated loading icon when opening the menus. The apps are somewhat slow to load, and we couldn't even get the YouTube app to load.
Update 06/22/2018: The YouTube app now works, but we have not found why it was not working during our previous testing. At the time of testing, only 14 apps were visible because the TV was connected to a Canadian WiFi network by mistake; when we connected to our U.S.A. VPN network 4 more apps appeared: Fandango Now, NBC, YouTube TV and Hulu.
There are no ads in the interface of the Vizio M-Series 2018, but there is a large banner of suggested content that can't be disabled.
Extremely limited selection of apps and smart features. On our M65 there were only 11 apps, and there is no app store. The most common apps are there, but the YouTube app wouldn't open for us and we had to cast YouTube from a smart phone.
There was a bug during testing, when switching rapidly from HDR to SDR the settings would not change and would stay on the HDR settings. They would change back only when the TV was powered off.
Update 06/22/2018: The YouTube app now works, but we have not found why it was not working during our previous testing. At the time of testing, only 14 apps were visible because the TV was connected to a Canadian WiFi network by mistake; when we connected to our U.S.A. VPN network 4 more apps appeared: Fandango Now, NBC, YouTube TV and Hulu.
Update 08/07/2018: Support for 4K HDR streaming on Amazon Video has been added with firmware version 1.0.18.4. The review has been updated.
Very basic lightweight remote. The buttons are very small and can be hard to read for some people, but the layout is intuitive and easy to use. There are 6 button shortcuts for various streaming services at the top of the remote.
There is no voice control built in to the remote or on the TV, but if you have a separate Google Home or Amazon Alexa device they can interface with and control the TV.
The remote app is good. It can replace the included remote and can be used to change inputs but not to open apps. The Vizio app can't be used to cast files from your device but third party software can be used to cast files to the built-in chromecast.
Differences between Sizes and Variants
We tested the 65" Vizio M65-F0. For the most part, we expect our review to be valid for the 55" version (Vizio M55-F0), and the 70" version (Vizio M70-F3).
If someone comes across a different type of panel or if their Vizio M-Series 2018 doesn't correspond to our review, let us know and we will update the review.
| Size | Model | Alternative Name | Clear Action | Effective Refresh Rate | Real Refresh Rate | Local Dimming Zones |
| 55" | M55-F0 | M Series 55 | 360 | 120 Hz | 60 Hz | 32 |
| 65" | M65-F0 | M Series 65 | 360 | 120 Hz | 60 Hz | 40 |
| 70" | M70-F3 | M Series 70 | 360 | 120 Hz | 60 Hz | 48 |
Compared to other TVs
The Vizio M-Series 2018 is a good mid-range 4k TV with a few minor flaws. It is a good improvement over the 2017 M-Series but faces some tough competition.
The Vizio P Series 2018 is better than the Vizio M Series 2018. The P Series has a more advanced local dimming feature that delivers deeper blacks and better dark room performance. Motion looks smoother on the P Series as it has a faster refresh rate, as well as an optional motion interpolation feature that can increase the frame rate of low frame rate content.
The TCL 6-Series (R615/R617) is better than the Vizio M Series 2018. The TCL R617 is better in a bright room, as it can get much brighter, especially in HDR. The R617 has issues with uniformity, so sports fans might find the Vizio is a safer choice. The Vizio M does not have any motion interpolation features, so if you enjoy the smooth motion provided by motion interpolation, the R617 is a better choice.
The Vizio M Series 2018 is a better TV than the Sony X850F unless you have a wide, bright room. The Vizio M Series has better picture quality and is better suited for dark room viewing. Motion looks better on the Sony X850F since it has a motion interpolation feature and is essentially flicker-free. The Vizio M Series 2018 also has better low input lag, great for gaming.
The Vizio M Series 2018 is better than the LG SK8000 for most uses but sports fans or daytime TV viewers will appreciate the wider viewing angle of the SK8000. The Vizio M Series has better picture quality and is better suited for a variety of room types. The LG SK8000 has a mediocre native contrast ratio and ineffective local dimming, so dark room performance isn't as good.
The Vizio M Series 2018 is better than the Samsung NU7100. The M Series has better picture quality and has better dark room performance thanks to the full array local dimming feature. The Vizio M Series 2018 has better motion handling, with a much fast response time so it has less motion blur. The Samsung NU7100 has a motion interpolation feature which the Vizio lacks, and it has better input lag.
