The Vizio M Series 2017 is a good 4k UHD LED TV that works best in a dark room. It produces deep and uniform blacks, and its great handling of motion and good input lag are a boon for gaming. Its local dimming feature isn't the best, but it still enhances the depth of the picture a good amount. Unfortunately, it isn't the best at handling reflections, and its viewing angle is quite narrow, making it less suitable for bright, wide living rooms.

Vizio M Series 2017 Design Picture
Curved : No

The design of the 2017 Vizio M Series is almost identical to the 2016 model. It has the same wide stand which looks quite good but may be difficult to fit on some tables. The borders are a bit thicker than average, but it still looks good overall and is a step up in design from the E Series 2017

Stand

Picture Quality

 The Vizio M Series 2017 LED TV has a good picture quality. Both the excellent contrast ratio and black uniformity make this TV a great choice for a dark room since it can display deep blacks without issues. In a brighter room, it will still perform okay with reflections, but if you have a very bright lamp or a sunny window straight on, it may have some difficulty fighting the glare. The gray uniformity is average but the dirty screen effect is not too problematic, so it is a good TV for watching sports like hockey or football. The only downside is that if you watch sports with a lot of friends, those sitting off center will have a worse picture quality since this TV has a poor viewing angle. Lastly, HDR on the M Series 2017 looks great. It has a good combination of wide color gamut, local dimming, and high HDR pick brightness, making HDR movies and games look very good and the difference between SDR and HDR is easily noticeable.

The contrast ratio is excellent on the 2017 M Series, even better than last year's M Series 2016. This high contrast ratio can provide excellent dark scenes performance with deep blacks, especially when the TV is set in a dark room.

When the local dimming is turned on, the contrast ratio goes up a little bit, but not by that much. This is a sign that the local dimming feature on the 2017 M Series is not as good as seen on other higher end LED TV, like the Sony X900E.

The local dimming feature on the 2017 M Series is not as efficient as that on the M Series 2016 since it has less dimming zones, but it still procures some benefit, as seen on our contrast ratio test and also looking at our black uniformity picture. While turned on, the local dimming helps to produce deeper blacks, especially if the TV is set in a dark room.

On the downside, like both the M Series and P Series 2016, the local dimming darkens the moving highlight too much. This is more visible when the highlight moves to a different dimming zone, and since the zones are even bigger than on the 2016 M Series, this is even more obvious.

Okay SDR peak brightness. The TV's local dimming dims highlights in dark scenes, as shown by our smaller window tests, which is not a good thing. This is the opposite of its HDR behavior, which brightens the small windows. The real scene brightness is close to the best case, but even it isn't very bright. This local dimming behavior is similar to the M Series 2016, but is a little better because the small windows aren't dimmed as much. A plot of brightness over time is shown here.

Great HDR peak brightness, though not as bright as high end TVs. The TV's local dimming effectively brightens highlights in dark scenes, as shown by our smaller window tests, yet its worst case brightness is still fairly bright. A plot of brightness over time is shown here. This brightness is a massive improvement over the M Series 2016, and though it is similar overall to the P Series 2016 the local dimming behavior is very different; the P Series dimmed the smaller windows rather than brightening them.

If you find HDR content too dim you can lower the TV's 'Gamma' setting. This doesn't affect bright white but will brighten everything else.

The gray uniformity is above average for this Vizio TV and is in the same ballpark as the 2016 M Series. Most of the issues come from the standard deviation being quite high and this is caused mostly from the sides and corners of the TV being darker than the rest of the screen. The 50% dirty screen effect test results is a bit higher than our good value number (0.165%), but dirty screen effect is minimal and is not too distracting.

When it comes to the 5% gray uniformity test, not many uniformity issues can be noticed besides a bit of a brighter edge at the bottom, but this is really not a problem at all since it is not noticeable while watching normal content.

The black uniformity of the 2017 M Series is excellent and it is an upgrade when compared to the 2016 models. Besides a bit of clouding in the bottom right and the top left corners, the rest of the screen is very even, which is great especially for dark scenes in movies.

With local dimming turned on, the uniformity is a bit worse since there is blooming around the middle white cross while the rest of the screen is mostly black. Note that in this test, we don't measure the black level of the screen, but rather the whole uniformity of the black. So even if the overall picture taken for the black uniformity with local dimming seems to have deeper black, the central blooming affects the final result.

Out of the box, the Vizio M Series 2017 has a great accuracy. The white balance dE is under 3, which very good since most people would not even notice it. The gamma is on our 2.2 target, but the overall gamma curve has some imperfections, but once again this would not be very problematic.

When it comes to the color accuracy, once again, the color dE is under 3, which is very good and most people could use the TV as-is and would not notice the little imperfections. Most of the issues here are because of the white points being a bit off and as a result of this, the overall dE of all the other colors are affected.

The calibration of the Vizio M Series 2017 was very easy to do and the whole process did not take very long. The 2 and 10 points white balance calibration is fairly responsive. The use of the smartcast remote app is a big plus when it comes to the calibration and it makes the whole process much faster.

After calibration the white balance dE is only of 0.13, which is almost perfect. With the color space management system provided by this Vizio TV, the color dE was cut in half, which is a really good result. The blue imperfections are very minimal and will not affect normal content.

Looking at the gamma, the curve was flattened to track more closely our target, which in the end is excellent.

Note: At the beginning of the calibration process, we encountered a bug that makes the 10 point white balance calibration inaccessible. A firmware update occurred during the review process and seems to have taken care of this bug and as a result, we could finalize the calibration process without any problems.

Vizio M Series 2017 EOTF

Wide color gamut, much wider than the M Series 2016 and very similar to the P Series 2016, but not as wide as many other high end TVs. Saturated red, blue and green all fall short of their targets, with green being the worst which is typical for modern TVs. The accuracy of the colors the TV can produce is not very good, as it severely undersaturates the lighter shades.

The TV's HDR EOTF most closely follows the PQ curve when the 'Gamma' setting is 2.4. This isn't actually gamma 2.4 as gamma is meaningless in HDR, but the 'Gamma' setting in HDR does raise and lower the EOTF. At the default 'Gamma' of 2.2 everything is brightened too much, as seen in this plot. However because HDR content is mastered for a dark room, you should lower the gamma (making the picture brighter) to suit the brightness of your room. The above two EOTFs were measured in the accurate 'Calibrated Dark' picture mode; the EOTF for the Computer picture mode with 'Gamma' 2.4 is here, and is identical to that of 'Calibrated Dark.

Mediocre color volume. The P3 volume is good, only really limited by the TV's color gamut and black level. The test was done with local dimming enabled, but still the black level never reached true black on our black-with-white-border slide. The P3 volume is fairly similar to that of the P Series 2016.

Looking at the Rec 2020 volume, fully saturated blues and reds are nowhere near as bright as they should be, blues especially. The E Series 2017 has a similar problem with saturated blue, but not red, and the M Series 2016 had no such issue.

Motion

The motion handling of the M Series 2017 is good. It has a quick response time, resulting in only a short trail of blur following fast moving objects. It is possible to clear this up significantly by flickering the backlight with the 'Clear Action' setting but this does produce visible flicker. Like the 2016 model, it can play movies from a Blu-ray player smoothly but some judder is present when watching movies from a HTPC or cable. Most people won't notice this though. Unlike the larger sizes of the 2016 model, this TV doesn't have any motion interpolation options.

The M Series 2017 uses PWM to dim the backlight, but at the high frequency of 480Hz so it isn't very noticeable. It is possible to enable 'Clear Action' to reduce the PWM frequency to 60Hz, and this helps to clear-up eye tracking persistence blur significantly, but produces a visible flicker. Note that the BFI option isn't available for HDR content as it reduces the brightness of the screen significantly.

Low input lag, which should be good enough for most people but competitive gamers may be disappointed. Unlike the 2016 M series this TV doesn't have a low latency port, so all ports measured the same for input lag. The picture mode doesn't matter for input lag, only the 'Game Low Latency' toggle matters, which can be activated in any picture mode. This input lag is nearly identical to that of the E Series 2017.

Aside: We measure input lag using the industry standard Leo Bodnar tool, connected to an HDFury Linker and Integral to change the resolution of the signal for the different tests. However when we tested using the Leo Bodnar tool alone, we measured ~29 ms, which is much lower than was measured using the HDFury chain. This is the only TV we've measured where the input lag from the tool was different than the input lag from the whole chain, because the Linker and Integral add less than 0.1 ms of lag each. To confirm our results we tested the input lag several times using the two screen method and TVs whose input lag was already known. All these tests measured an input lag between 40 and 43 ms, confirming our previous result of ~40 ms. This shows that our input lag results are valid for typical sources like game consoles and PCs.

The Vizio M 2017 runs Vizio SmartCast, which has no apps of its own and instead plays content cast from a smartphone or tablet, much like a Google Chromecast. There is a SmartCast app for phones and tablets that can be used to change the TV's settings and manage content. However, this year's SmartCast also has a better physical remote that can change the TV's settings on its own, so now a phone or tablet is only needed when playing content from apps.

SmartCast does have some limitations. Content can be played from a USB drive but control over its playback is very crude. When a USB drive is plugged in, the TV plays the first file immediately until it is finished, then moves on to the next file. Playback can only be played/paused, there is no option to skip files. HDR files are not played in HDR via USB. Another limitation is the TV's lack of a built-in tuner, so you cannot connect a cable or antenna directly to the TV, though you can use an external tuner like this one.

Apps

The TV has no apps of its own, but it can play content cast from many apps on a smartphone or tablet, such as Netflix and YouTube. However, Amazon Video cannot cast to SmartCast or a Chromecast and so requires an external player (such as a Roku stick). Netflix videos can play in 4k HDR, and YouTube videos can play in 4k but not HDR; this isn't unusual though as YouTube HDR support is fairly rare on TVs.

Remote : Basic

The Vizio M 2017's remote is a considerable improvement over the very basic remotes from last year, but the TV does not come with an included tablet like the 2016 M Series. Settings menus have been added to SmartCast on the TV, and the remote now has enough buttons to access these new menus. All the settings that once required the SmartCast app to change can now be changed using the remote. However the remote is still fairly basic and lacks smart features like a microphone or a pointer, like the smart remotes of other platforms.

Bottom right: Samsung MU6300 (UN55MU6300).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The M Series 2017 is a good performer at its price, and offers some of the features found on the more expensive Vizio P Series 2016. It is generally a good pick over its direct competition.

Vizio P Series 2016
50" 55" 65" 75"

The P Series is a little brighter than the M Series in SDR and has a significantly lower input lag. Since it has a much better local dimming feature and deals with gradients better than the M Series, it does a bit better for HDR. Overall, if you can afford it, it is a more complete package than the M Series 2017. 

Sony X800E
43" 49" 55"

The Sony X800E is a similarly priced 4k LED TV that features a wider viewing angle. It's about as bright, but it deals with upscaling lower resolution content better than the Vizio, making it a better choice for daytime TV shows. In a dark room though, the Vizio M 2017 does much better, since its blacks are a lot deeper and it has local dimming, which the Sony lacks. The M Series is usually found a bit cheaper, but choosing between the two depends on your use-case. 

Vizio E Series 2017
50" 55" 60" 65" 70" 75" 80"

The E Series 2017 is a cheaper LED TV from Vizio. It lacks a few HDR related features such as wide color gamut, and it doesn't get as bright, but it performs very similarly with SDR movies in a dark room. If this is the bulk of your consumption, it can be worth saving your money and going for the E Series, but it is far less versatile than the M Series 2017.

Samsung MU6300
40" 43" 50" 55" 65" 75"

The MU6300 is Samsung's entry-level 4k LED TV. It doesn't have fancy features such as local dimming or wide color gamut, but it has a lower input lag than the Vizio. While the MU6300 deals with upscaling of lower resolution content a little better than the M Series 2017 and has a more intuitive set of smart features, it's usually slightly more expensive. Overall, the Vizio offers better value for money.

Show Help
What it is General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
The M Series 2017 is a good TV for a mixed usage. It has good picture quality in a dark room, good handling of motion and features a nice set of HDR related features.
8.2Movies
Show Help
What it is Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
Great choice for movies in a dark room. The Vizio M produces deep and uniform blacks, and it sports a decent local dimming feature that enhances its contrast further.
6.8TV Shows
Show Help
What it is TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
The M Series 2017 does an ordinary job with TV shows. It gets decently bright, but it doesn't do a great job at handling reflections. Unfortunately, its upscaling capability is average as well.
7.4Sports
Show Help
What it is Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
Score components:
Decent TV for watching live sports. The Vizio M series handles motion well, and it produces a uniform image free of major blotchiness. Unfortunately though, picture quality does degrade at an angle.
8.5Video Games
Show Help
What it is Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
Score components:
Great TV for video games. The Vizio M 2017 has low input lag and motion blur. Games feel responsive, and its image flicker feature can greatly enhance the clarity of motion.
8.3HDR Movies
Show Help
What it is HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
The Vizio M 2017 handles HDR movies well. It gets decently bright, and it can reproduce a slightly wider range of colors. It's not the best at handling gradients though.
8.3HDR Gaming
Show Help
What it is HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
Very good HDR gaming performance. An HDR input doesn't affect the input lag of the M Series 2017, making it a good choice for HDR consoles.
7.2PC Monitor
Show Help
What it is PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
The M Series 2017 makes for an average PC monitor. While it supports the necessary resolutions for sharp text, the narrow viewing angle causes edges of the screen to darken from up-close. The input lag, while fine for more casual gaming, can also seem a bit sluggish for use with a mouse.

Is the 2017 M Series an upgrade over the 2016 model?
Depending on your use, it may be. The 2017 model has a similar wide color gamut to the P Series 2016 and gets brighter resulting in a better HDR experience. For SDR content though, it is slightly worse due to the fewer local dimming zones resulting in worse dark scene performance. The 2016 model also has better input lag for SDR only, due to the game low latency port. If you plan to watch a lot of HDR content or play HDR games then go with the 2017 M Series, but otherwise go for whichever is cheaper.
1
Can the new remote be used on the 2016 models?
We can't confirm if it will work on all the 2016 models, but it worked on the P Series 2016 (and E Series 2017) on the latest firmware. It seems the on screen menus were added to some or all 2016 models even though they don't come with the remote needed to access them.

Would you recommend the M70-E3 or P65-C1? Or even M70-D3? All 3 are exactly the same price where I'm looking. Mostly used at night. TV/Movies and gaming all probably equal usage (4k gaming on Xbox One X eventually and PS4 Pro). Wall mounted over the fireplace. Sit about 11 feet back.
Go with the P Series 2016 (P65-C1). At the same price, you will be getting a bit more for your money with the P Series. The local dimming feature is much better than on the M Series 2017 (M70-E3) and you will have the wide color gamut (which is important for HDR) that is not available on the M Series 2016 (M70-D3).

Why would the input lag be different when the HDFury is added to the chain? Could it perhaps be related to the HDMI/HDCP version being different? Was the increase in lag a consistent +10ms in all your tests?
This is the only TV for which the input lag from the Leo Bodnar tool was different than from the whole chain. The TV processes the signal from the tool differently than how it processes the signal from any other source. The 'Game Low Latency' toggle does nothing, and sharpness is disabled. We don't know what's different about the tool that makes the TV handle it differently, but any game console or PC will not be processed this way. We do know the tool sends an odd HDMI signal, as the HDFury Linker will not accept the signal from the tool if it's not passed through the Integral first. The only tests we can do using the tool alone are 1080p @ 60 Hz in game mode, out of game mode and with interpolation, which were all ~29 ms because the 'Game Low Latency' toggle does nothing and the TV doesn't have interpolation.

Does the higher peak brightness make the M Series 2017 a better choice than the P Series 2016 for HDR movies?
The P Series 2016 is definitely better for HDR movies. The P Series has higher HDR real scene brightness, which is the most important test, so the M Series 2017 will only have brighter highlights during really dark scenes. The P Series's local dimming is also far better.

I was going to buy a 2016 M65 but knew the 2017 M65's were coming soon so I waited. Now I see this review and the 2017 M's went from 120Hz to 60Hz refresh rates, no motion interpolation option AND their lag input when from a low of 17.1ms 1080@60Hz on the '16 to a not that great 40.4ms 1080@60Hz on the '17. A non-TV expert like myself would say the 2017's are worse than the 2016s?
In some ways it is worse, but it does offer some advantages for HDR. It's significantly brighter, and it sports a wide color gamut, which the previous model lacks. If your usage doesn't really focus on HDR that much, then you might be better off with the 2017 model.

On your Vizio M 2017 Review when it comes to gradient does the Vizio M 2017 do a good job with gradients? Like would you see any banding? I had a tv with bad banding on gradients, and it really bothered me. I just wondered because you gave the Vizio E 2017 a 9.5 for gradient and then the Vizio M 2017 an 8.5. Just wondering if the gradient on the Vizio M 2017 is good. Thanks

The Vizio M Series 2017 banding is a bit worse than on other TVs when it comes to 10 bit content like HDR UHD Blu-rays. We displayed the same scene from The Martian movie (at 00:46:36) that we already did a test on for the comparison between the Sony A1E and the LG C7 and the Vizio M Series 2017 did have more banding in comparison.

Here are the picture of the banding comparing the Vizio M Series 2017 with the LG C7 and the Sony A1E.

Can the M series display HDR content from a 4k HDR video file via Kodi?
While you cannot install apps such as KODI on the Vizio M itself, it does support the casting of files through kodi using the "Yatse" remote app. Unfortunately though, the Vizio M doesn't appear to support casting HDR files or files encoded using the H.265 codec, so it will not be compatible with most HDR content.
