70 inch TV Reviews – Best Guide for 70 inch Smart 4k Ultra HD TVs for Sale – Buy a 40 inch LED, Flat Screen Television with Confidence!



Like their 60 inch cousins, the 4K ultra HD TVs in the 70 inch range are few and far between. This is a size that tends to get neglected in favor of more popular and comfortably sized models in the 55-65 or 75 to 80 inch range. Thus, the following is going to be a rather short list but one that covers some interesting models which don’t normally feature in the top rankings for smaller or larger TV ranges.

At 70 inches, a 4K TV is definitely big enough for some serious appreciation of 4K resolution to be possible at both close and further distances and at 70 inches, a 4K TV is also quite impressive to behold in a living room without having the truly gigantic dimensions of an 80 inch model. This is a major point in favor of any 70 inch model you get your hands on. So is the somewhat odd fact that, oddly considering their size, most of the following TVs are very affordably priced while offering plenty of high quality in return.

Also, for a thorough overview of some factors to keep in mind for all 4K TVs, take a look at our analysis of connectivity, visual specs and other common 4K TV features after the TV listings themselves.


A Note on Viewing Distance

Ideal viewing distance is a result of two key factors: On the one hand, you want a 4K TV to be far enough away so that its native resolution looks sharp and clear enough for pixels to not be noticeable while you also want it to be close enough for a serious appreciation of the so-called immersive experience. For the rather large displays of 70 inch ultra HD televisions, this ideal viewing distance is about 9.5 feet, or 2.9 meters. However, there’s room for flexibility in this and you can still enjoy a very fine display quality from closer distances of even as little as 8 feet thanks mainly to the high pixel density of 4K, or from larger distances of 10 feet or more thanks to the very broad real estate offered by a 70 inch display.

The 3 Best 70 inch 4K TVs today

As we’d said, in the 70 inch range, 4K UHD TVs become rather scarce since most major brands seem to avoid this size in favor of 65 inch or 75-80 inch models. However, for those of you who are dedicated to the idea of having a 70 inch 4K TV in particular, there are still a few very good and even in some ways excellent models to be found, mainly from Vizio’s unique 4K TV offerings but also from Sharp’s less well-known Aquos line of 4K TVs.

All of the following 70 inch models offer both native 120Hz refresh rates and 3D technology unless otherwise stated in a particular description.

Vizio M70-D3 2016 M-Series 4K HDR TV: $1,999


Vizio has absolutely ramped up the quality of its 4K TV offerings in 2016 and while the affordability of these newer models has also slightly decreased compared to 2014 and 2015 Vizio TVs. the quality they bring to a home entertainment system more than makes up for this. The 2016 M-Series is a superb example of this at work and it offers the kind of specs that would have cost several thousand dollars in almost any major 2014 4K TV.

The M-Series lacks the wide color gamut coverage of its P-Series cousin but it is still considered an HDR 4K TV with a high level of peak brightness, excellent SDR color performance and some superb motion handling specs as well. Furthermore, its one of the cheapest 4K TVs with full-array LED backlighting that you’ll find on the market today. Thanks to the inclusion of this technology, the 2016 M-series also naturally enough offers some excellent local dimming which is quite a bit better than that found even in premium 2016 TV models like Samsung’s SUHD TVs. Overall, the M-Series is a superb budget offering and at $2000 for a 70 inch television of this caliber, it’s a superb deal.


Vizio M70-C3 M-Series 4K UHD Smart TV: $2,048.49

Vizio M70-C3 M-Series 4K UHD Smart TV:

Vizio’s M-Series 4K TVs are some of the most affordable quality options on offer in today’s market across all of their numerous size ranges, and the same applies to the 70 inch model M70-C3. This is one very decent 4K TV across the board and while it lacks some of the same major features that the P-Series above does, including active 3D technology, web browsing and smart remote functionality or advanced smart TV features, the M-Series does offer excellent upscaling technology for HD content, great color accuracy and some truly fine contrast quality. It also delivers excellent black uniformity and basically perfect judder control for 24p content along with perfect motion interpolation technology.

On the other hand, once again, no web browsing, slightly limited streaming 4K content access due to a lack of the VP9 video compression codec and poor upscaling of both 480p and 720p content. We also don’t like the usability of the Internet Apps Plus smart TV platform in Vizio’s 2015 4K TVs.

LG 70UF7700 4K UHD LED smart TV: $2,497.99


LG’s UF77000 is definitely not the best 4K LCD TV on the market when stacked up against some of the contenders in the 65 or 75 inch ranges but among 70 inch 4K TVs it’s a powerful piece of technology which has one major feature really working for it more than anything else –it’s superb WebOS 2.0 smart TV platform. WebOS is definitely a winner across the board and we consider it to be the best smart TV system in existence at the current time. In the case of the UF7700, the WebOS 2.0 platform is also accompanied by the company’s superb smart TV platform. Moving beyond these things, the UF7700 also offers a superb upscaling engine and some very high quality judder and motion control performance. It also offers solid performance as a gigantic 4K PC monitor if that’s something you’d like to use it for.

However, and this is a constant problem we’d noted for 2015’s LG LCD 4K UHD TVs, the UF7700 is a very weak performer on contrast, black uniformity and local dimming. The black uniformity in particular is a disaster in this TV and makes you wonder how the same company also produces the exquisite and uniform technology of OLED in contrast. Furthermore, among the models presented here and in comparison to other 4K LCD models, the UF7700 is overpriced for the quality it offers. Were it not for its WebOS 2.0 platform and some excellent motion control specs, it wouldn’t be on this list.




Connectivity for 4K TVs from all major brands is pretty much across the board. Some TVs will offer one more or one less HDMI or USB port and you might find a TV here and there with DisplayPort attached to it as an unexpected bonus but generally, all current 4K televisions offer the same core essentials which we’re about to go over.

HDMI: HDMI 2.0 is the current standard spec in the majority of 4K TVs and a new variant of it called HDMI 2.0a is also increasingly being found in newer TV models for the sake of allowing them to receive HDR content from HDMI-connected external devices like 4K Blu-ray players and set-top boxes. HDMI is your TV’s most important spec and it’s what allows the TV to access UHD content from external media devices at a smooth 60 frames per second. Thus, most 4K TVs will come with at least three HDMI 2.0 ports and these ports will also typically include standardized compatibility with HDCP 2.2 content copy protection, HEVC (H.265) 4K video compression encoding and in some models, VP9 video compression as well.

Internet Connectivity & WiFi: Coming right after HDMI in terms of importance, there is your TVs Ethernet port that allows the television to connect to your domestic internet service package. Ethernet is crucial for access to streaming media apps of all types and particularly for access to streaming 4K media sources like Netflix and Amazon Prime Instant Video. Furthermore, the majority of your 4K TV’s essential smart TV features like search and web browsing depend on you having the television connected to the web via Ethernet.

There is also a caveat in place here. For your TV to be capable of streaming 4K UHD content, you not only need to have it hooked up to the internet via Ethernet but that internet connection should also be of a strength of at least 15 to 20 Mbps, and most ideally offer at least 25 to 35 Mbps for streaming of smooth and even live 4K content from assorted sources, now that these sorts of canned and live 4K streaming services are expanding in scope.

USB: Your 4K TV will include at least 2 to 4 USB ports and for most models on sale today, these ports will be of the USB 2.0 variety, with maybe one or two offering the even more powerful USB 3.0. USB isn’t powerful enough to transmit 4K video from external devices to TV but it can be used for charging such devices through your TV, or for connecting gaming controllers, smartphones, and tablets for functionality and media transfer between them and your TV. All of the 4K TVs in this list offer at least three USB ports, with at least one USB 3.0 port usually on offer as well.

Smart TV Platforms

All 4K TVs worth buying and all such TVs from any major brand offer up smart TV platforms of one kind or another for their 4K televisions. The best smart platforms on the market, such as LG’s WebOS 2.0 and WebOS 3.0 come with interactive voice search and gesture control features as well as an accompanying smart remote control. Many smart platforms also offer up the ability to set up individual user profiles, browse the web and access thousands of different TV content and other media apps.

Some particularly great smart TV platforms include Samsung’s Tizen smart TV OS and the Android TV platform found in most Sony 4K TV models. We also like Panasonic’s Firefox TV platform. The Vizio 2016 TV in the list above does have a decent smart platform in it. This is called SmartCast and it supports full web browsing while also being usable from a wide range of external mobile devices, to which it’s mobile interface can be downloaded, with solid access to most mainstream 4K and HD media apps usable via SmartCast as well. However, in the case of the 2015 Vizio M-Series 4K TVs, they do not offer full web browsing.

Native 4K display extras and Upscaling

What makes 4K TVs such excellent devices isn’t even really just their native 4K resolution and all of its pixels. Yes, 4K increases display sharpness but in smaller TVs, viewed at normal distances, the 4K won’t even be distinguishable from Full HD to most people’s eyes. No, instead, what really delivers the goods in a quality 4K TV is the caliber of its associated display specs like contrast, non-4K content upscaling,  enhanced color, the inclusion of high dynamic range and the peak brightness that the TV offers, among other things. This is the technology which will cause one 4K TV to perform so much better, or worse, than another model. All of the above models offer some degree of quality in their display specs for color, contrast and upscaling.

And speaking of upscaling, it’s one of the most crucial display features in any 4K TVs for the simple reason that most content available to these televisions today won’t even come in native 4K resolution. This applies particularly for broadcast TV content. Thus, how well your particular 4K TV can take ordinary 720p or HD content and reprocess it so that it looks sharper on the native ultra HD display, then also offer that content the benefit of the TVs high quality color enhancement and contrast or HDR specs is what will really set that 4K TV apart from an ordinary HD model.

HDR technology is also a crucial feature of the leading 2016 4K TVs across assorted size ranges. With high dynamic range, display quality takes a major leap upward and the 2016 standards for HDR that the top four 4K TVs in this list have adopted are considerably better than what we saw of this technology in 2015. For an even more detailed breakdown of how the HDR technology in 4K UHD OLED and LCD TVs works, check out our guide to high dynamic range for a complete overview.

Local Dimming & Backlighting

All backlighting and TV screen illumination technologies can be basically divided into two broad categories. The first is OLED and the other is LCD/LED. All of the 4K TVs we covered in this list of the best 70 inch models are LCD TVs, since no manufacturer has yet released a 70 inch OLED model to the market. However, as a general rule, OLED is by far the superior technology of the two. We won’t go into details on how OLED and LCD stack up on the quality of their local dimming, contrast and brightness delivery but our thorough comparison of both display technologies covers everything you’d need to know.

For now we will however say that LCD TVs like the models above offer local dimming by selectively turning off their backlight LEDs in different sections behind the screen. For Full-array LED TVs like the two Vizio models, this technology produces a pretty precise level of local dimming for select dark/light regions of on-screen content. However, in edge-lit LCD TVs like the UF7700, local dimming is generally weaker and more ambiguous, with a notable halo effect created around bright objects on a dark background.

    Don’t you get the 70 inch Samsung 6300 in USA? I just picked one at Bestbuy in Canada and I’m surprised that you are not mentioning it in the 70 inch or 6300 pages.
