by on November 9, 2016

Vizio M70-D3 and E70u-D3 are a few models of 70 Inch 4K TVs that released in 2016. Both of them are parts of Vizio’s 2016 LED TV lineup M and E series. One of the main technologies behind them is Full Array LED Backlighting with Dimming Technology called Active Led Zones. In the market M70-D3 is sold about $2000 while the lower series Vizio E70u-D3 is sold about $700 cheaper. For their price range, their difference in price can be said very significant. But of course, like the price of other electronic devices, it usually will tend to go down as time goes by. So, what are the differences between them so Vizio M70-D3 is sold about $700 more expensive than E70u-D3? And which is a better choice between them considering their difference in price?

Vizio E70u-D3 Review

Vizio E70u-D3 is part of Vizio’s 2016 E Series. Although it comes with 4K resolution, but unlike most of 2016 Model 4K TVs that available in the market, it doesn’t support HDR. The other big downside of E70u-D3 is about 3D technology where there is no 3D technology behind it. Like the predecessor, it is powered by VM50 Ultra HD engine as its image processor. Additionally, there is also Spatial Scaling Engine that does a good job when up-scaling lower resolution contents to 4K quality. The other advanced technologies behind them are Full Array LED Backlighting with local dimming called Active LED Zones where it comes with 12 dimming zones. This course becomes an advantage of Visio E70u-D2 than its competitors considering there is not much low end 4K TVs that comes with Full Array LED backlighting and local dimming. Moving on motion handling, Vizio E70u-D3 is powered by Clear Action Rate 240 based native 60Hz Hz refresh rate pane. And for completing your 4K home entertainment, it features Smart TV platform called Smart Cast instead of Vizio Internet Apps Plus and powered by V8 Processor as the combination of quad core processor and quad core GPU.

Vizio M70-D3

Vizio M70-D3 is pats of Vizio’s 2016 M series, one level above E series. Like the E series, it is also powered by VM50 Ultra HD engine as its 4K processor. As its UHD Up-scaling engine, it is also powered by Spatial Scaling Engine. Additionally, there is also Active Pixel Tuning and Pure Cinema Engine that optimize its performance when processing 24p movies. When handling Motion Picture, Vizio M70-D3 is powered by higher level technology that is Clear Action Rate 720 based on effective 240 Hz or native 120 Hz refresh rate panel. It is also comes with Full Array LED Backlighting with local dimming but has more dimming zones that is up to 64 zones. In addition to higher level technologies, HDR (High Dynamic Range) is the advantage of Vizio M70-D3 than E70u-D3 where it already supports HDR 10 and Dolby Vision HDR format. This means you can play both HDR formats HDR 10 and Dolby Vision on M70-D3. And like the E series, it features Vizio Smart Cast apps as its smart TV platform and also powered by V8 Octa Core Processor and as we know, it is combination between quad core GPU and Quad Core CPU that offers fast and powerful performance. A big downside of M70-D3, there is no 3D technology behind it.

The Differences between Vizio M70-D3 and E70u-D3

Active LED Zones

Both of Vizio E70u-D3 and M70D3 come with Full Array LED Backlighting with local dimming called Active LED Zones. The difference between them is about the number of dimming zones where M70-D3 comes with 64 dimming zones while E70u-D3 comes with 12 dimming zones. With the differences in the number of zones, this makes a big difference in black level and contrast reached by them. Vizio M70-D3 with 64 zones of active led zones can reach about 0.021 nits of black levels with contrast ratio about 47050 : 1 while black level reached by E70u-D3 is about 0.030 nits with contrast ratio about 3340:1. This shows that black level reached by M70-D3 is deeper with higher contrast ratio than what produced by E70u-D3. But even so, although black level reached by E70u-D3 is slight brighter than M70-D3 but for its class, it is a cheap TV with deepest black level.

Active LED Zones

Motion Handling

As we see on comparison table above, when handling motion blur, Vizio M70-D3 is powered by Clear Action Rate 720 based n effective 240 Hz or native 120 Hz refresh rate panel while Vizio E70u-D3 is powered by Clear Action Rate 240 Hz based on effective 120 Hz or native 60 Hz refresh rate panel. The result, M70-D3 offers faster pixel response time than E70u-D3. This means when they used for watching video contents with fast scenes, motion blur will be more noticeable on the screen of E70u-D3 than on the screen of M70-D3. Additionally, with Pure Cinema Engine behind it, M70-D3 also does a better job with judder-free when playing 24p contents while the judder cannot be removed completely on the screen of E70u-D3 when it is playing 24p contents like Blu Ray movies. But even so, when they are playing 24p contents over 60i and 60p signals, the performance of both is the same not so good.


As we have mentioned above, there is some major differences between them that has a big impact on their picture quality. One of the major differences between them is about HDR where Vizio 70-D3 already supports HDR formats, HDR 10 and Dolby Vision while Vizio E70-D3 doesn’t support HDR though it already comes with 4K resolution. But talking about HDR performance that offered by M70-D3, of course this has to do with the picture quality produced by it.


As we know, for displaying HDR contents fully whether it is HDR 10 or Dolby Vision, this need a certain standardizations of black level, peak brightness, color gamut, and depth of color. In term of contrast,HDR10 need 0.05 nits of black level and 1000 nits of peak brightness while Dolby Vision need 0 nits of black level and 10000 nits of peak brightness. Additionally, in term of color, HDR 10 need more than 90% of DCI P3 color space with 10 bit depth of color while Dolby Vision need REc.2020 color space with 12 bit depth of color. A 4K TV meets minimum standardization of HDR 10 entitle to get Ultra HD Premium Certification set by UHD Alliance.

DCI P3 vs Rec.2020

But unfortunately, although Vizio M70-D3 already supports both of these HDR formats, its display specs are far below what needed. Black level reached by M70-D3 may lower than needed that is about 0.21 nits of black level, but in term of peak brightness, it is far below. A peak 25 Windows is only 195 nits while the brightest peak brightness is reached on 25% window that is 413 nits. For TV with VA panel, this certainly is not bright enough, even it is not quite enough to match what reached by LG UH7700 that use IPS Panel. This result is better than what reached by Vizio E70u-D3 where its peak brightness reached is 300 nits on all % windows and black level reached is 0.03 nits of black level. But we must remember, Vizio E70u-D3 doesn’t support HDR so what reached by it can be said quite enough.

Moving on color performance, what reached by Vizio M70-D3 is also below minimum standardization of HDR 10. Color gamut delivered by it only can cover about 81% of DCI P3 color space. Additionally, its depth of color is also only 8 bits that’s mean it only can delivers about 16 million shades of color. As comparison, a TV with 10 bit depth of color can deliver about 1 billion shades of color. Of course this makes color gradient offered by M70-D3 is not as smooth as what delivered by 10 bit TV. This means color performance offered is only quite enough to display Rec.709 contents but not still enough to display HDR 10 contents fully, moreover for Dolby Vision that has higher standardization. While what reached by Vizio E70u-D3 is also not much different to what reached by M70-D3. But once again, E70u-D3 doesn’t support HDR so color performance that offered can be said well for normal or SDR contents.

From display specs that offered by them, we can concluded that Vizio M70-D3 is superior to E70u-D3 on contrast and black level, while color and peak brightness is not too much different. One benefit of M70-D3, it can play HDR 10 and Dolby Vision contents though not with the expected quality.


The Similarities

Up-scaling Engine

For up-scaling lower resolution contents to 4K quality, both Vizio M70-D3 and E70u-D3 is powered by Spatial Scaling Engine. Separated from their difference performance in contrast, performance offered by them is virtually identical. The best result is delivered when the resolution of the source is 1080p like from Blu Ray Movies. Both of them do a good job up-scaling 1080p contents to 4K quality without loss any details. But even so, when the source is 480p like DVDs or 720 like Cable TVs, although can be said great but their performance is not as good as what offered by other TVs from other manufacturers like LG, Samsung, or Sony. When displaying the line on 480p, it will look choppy in other hand when it is displaying from 720p contents, small details will look slightly lost.


Smart TV

As their Smart TV platform, both Vizio E70u-D3 and M70-D3 features Vizio Smart Cast Apps that powered by V8 Octa Core processor. You need to know, V8 Processor is the combination of a quad Core GPU and quad Core processor that offer powerful performance for handling video streaming. Actually this platform is similar to ChromeCast.  It offers unique experience in watching TV with all conveniences to discover, cast, and control music, TV shows, and movies and many more. The unique from Vizio Smart Cast, there is no apps on the actual TV itself. To use SmartCast, you need first to connect your TV with your mobile devices or table support Vizio Smart Cast and has many applications that support casting. Then you need to launch and enable a Google Cast app and tap the cast button to send a Video to your TV. Fortunately, there are many apps that already support casting such as Spotify, YouTube, Netflix, and many more.

Vizio M70-D3 comes with 6” 720p tablet remote based on Android Lollipop that already installed Visio Smart Cast Apps in its buying package, so you don’t need to buy a Tablet Remote separately. But for Vizio E70u-D3, there is no Smart Tablet or other handheld included in its buying package so you have to use your own handheld devices or buy separately to still be able to use casting service.


There is bit difference between them about the number of HDMI Port as their major connectivity. Vizio M70-D3 s equipped with 5 HDMI Ports while Vizio E70u-D3 is equipped with 4 HDMI ports. The excepting of the number of HDMI ports, both of them are equipped with the same input/outputs, that is 2 HDM Port, 1 Audio Out Analog (RCA), Audio Out (Optical), 1 Component In, ad 1 Ethernet. There is no Composite IN and RF (Terrestrial) input. This means both of them is not equipped with built-in Tuner. So, to connect an antenna or cable to your TV, you need to buy a tuner separately.

Sound Quality

Sound quality that offered by Vizio E70u-D3 orM7-D3 is very poor. The middle frequency and high frequency or treble is sounded loud but there is much distortion. Moreover there is no built-in woofer behind it that makes its bass or low frequency is also very poor. Even this is worse than cheap sound bar. To improve their sound quality, you need t invest a sound bar, except you are already with poor sound quality that offered by them.

HDR (3.1/5) (4/5)

As mentioned, Visio M70-D3 and E70u-D3 is parts of few 70 Inch 4K TVS that released in 2016. Full Array LED Backlighting with Local Dimming technology is the mainstay technology behind them. As cheap TVs, their performance is not so disappointing. The main difference between them is about the number of dimming zones called Active LED zones where M70-D3 comes with 64 dimming zones while E70u-D3 comes with 12 dimming zones. As the impact, Vizio M70-D3 offers deeper black level and strong contrast than Vizio E70u-D3 although for its class, the contrast produced by E70u-D3 can be said strong particularly its black level.  The other major difference between them is about HDR where Vizio D70u-D3 doest support HDR whileM70-D3 already supports two formats HDR at once, HDR 10 and Dolby Vision although in term performance, it still far below than what expected.

Both of them also has difference in the number of HDMI ports whereM70-D3 is equipped with 5 HDMI ports while E70u-D3 is equipped with 4 HDMI ports, But even so I think 4 ports is quite enough considering most of top level LED TV or OLED TVs are also equipped with 4 HDMI Port. The other difference is Vizio M70-D3 is included Smart Tablet in its buying package as the smart controller of Vizio Smart Cast while on Vizio E70u-D3, there is no Tablet included in its buying package.

So, which is a better choice between them? As mentioned, both of them are sold with difference in price about $700 where Vizio M70-D3 is sold more expensive than Vizio E70u-D3. And I think $700 is comparable to advantages and Smart Tablet that offered by M70-D3. Now the decision comes back to you according to your need and budget. I just try to give an overview between them before you decide to buy them. Bu even so, before you decide to choose one of them, there are many opinions from their real users where you can make them as your further consideration
