Q&A: What Is The Best 70 Inch 4K TV?

Our team scoured the web looking for the top television models and we ultimately determined best 70 inch 4K TV is VIZIO's M70-E3 . We chose this television as our Editor's Choice based on its design, feature set and performance for the reasonable price-point.

However, if you have the flexibility of choosing a slightly smaller or larger sized screen, you'll likely find more overall bang for your buck if you were to purchase a 65 inch or 75 inch models. 

Those who have the space to accommodate a larger 75-inch 4K TV, we think the LG 75SJ8570 is the ideal choice for most people. This model offers a great panel mixed with Harmon Kardon speakers, a stellar webOS and supports the two most popular HDR formats.

If you'd rather drop down a size and go with a 65-inch 4K TV then LG's OLEDC7P is going to be the optimal choice for most. While more expensive than many larger models, the OLED display provides perfect blacks, increased contrast ratios and excellent viewing angles.

Where are all the 70 inch TV models?

If you've already begun your hunt for a new television at this size, you've probably run into a dilemma. Why are there barely any 70 inch TV models to choose from?

For example, a quick search for a 70 inch 4K TV on both Amazon and B&H only bring up a combined total of four different models. Included in these results are three newer models from VIZIO and Sony as well as a discontinued Samsung TV released in 2016.  

While these are all reputable brands, some of you may be scratching your head as to why there aren't more models to choose from. The reason for this is television manufacturers tend to stick to a general sizing formula that follows the industry's standards for screen sizes. 

You'll see a lot more variations of TV sizings under 32", but after surpassing this mark you'll traditionally see the screen sizes as follows (measured in inches from corner to corner):

  • 32 inch​​​​
  • 40 inch
  • 42 inch
  • 50 inch
  • 55 inch
  • 60 inch
  • 65 inch
  • 75 inch

What to look for in a new TV (2018)

Technology has come a long way over the past decade. When making a large purchase like a television, you are better off buying a TV with all the bells and whistles that will last you 5-7 years than a cheaper model that will only last 1-3 years. Here is what you should look for when choosing a new model:

1) 4K UHD (Ultra High Definition) resolution

Over 81.9 million 4K UHD TVs will have been sold during 2017 according to a study from Statista. This is a staggering number when you consider this figure was as low as 10.2 million just three years earlier (2014). 

4K Ultra High Definition is exactly four times the amount of pixels as Full HD aka 1080P. The larger pixel count makes the television's resulting image offer more clarity with cleaner lines. 

Here's a video that expresses the differences more effectively: 

While it is true that traditional TV content providers like Comcast, Time Warner Cable or DISH haven't yet adopted native 4K programming, it will transition to this over the next 3-5 years just like it did with standard definition to HD. 

Additionally, you can access 4K UHD content through streaming services like YouTube or Netflix as well as on game consoles like the Xbox One X or PS4 Pro.

2) High Dynamic Range (HDR)

By definition, HDR is the concept that a display panel can produce more shades of luminance (brightness) between the darkest and brightest areas of an image.

With the increased amount of detail in the shadows and highlights, you receive a better overall viewing experience along with a higher number color variations thus making the image feel truer life. 

HDR is making its way to mainstream in the same fashion as 4K UHD with content being offered by services like Youtube, Netflix or Amazon Video as well as through the latest game consoles. 

While many models market themselves as HDR-ready, there are several standards which depict the how good the HDR is. For example, the three most common standards in consumer televisions are currently HDR10, Dolby Vision and Hybrid Log Gamma (HLG). 

HDR10 is the more common standard that televisions will ship in compliance with, but Dolby Vision is a brighter, more colorful version of HDR offering millions more screen color variations. 

Without getting overly technical, most TVs that ship supporting Dolby Vision do not offer a panel with enough color depth (10-bit versus 12-bit) to handle the full capabilities of Dolby Vision, but there is still a noticeable improvement over HDR10 with supported content. 

3) Smart TV functionality

Since the shift to interconnectivity between televisions and the Internet, smart TVs have been around for several years now. Do to this, 4K UHD models have become followed the standard to ship with smart TV functionality from the start.

These smart TV capabilities will allow you to access streaming services like Netflix, Hulu, Amazon Instant Video, Crackle and more. In some cases, you can even surf the web, see the weather predictions or browse your Facebook feed. 

It is also important to note that not all smart TV operating systems are not all equal meaning that some may perform better or offer more features than another.

At the 70-inch TV size, you will almost always find these 4K models shipping with integrated Smart TV technology so be sure to verify this before buying. 

If it doesn't offer this feature, you'll likely want to invest in a Chromecast, Roku or Amazon Fire TV to supply smart TV functionality. 

4) High Refresh Rate

A display panel's "refresh rate" is defined as how often the TV changes the image or 'frame' on the screen. This means a 60Hz panel will change 60 times per second. The higher the number, theoretically the better the performance will be especially with fast motion like sports or gaming as you decrease the level of visible motion blur. 

You'll want to try to purchase a model with a high refresh rate such as 120Hz which is fairly common at the 70-inch size. Ideally, you'd like to choose a model with a 240Hz refresh rate although this is not commonly offered in 4K models and more common in 1080P versions at this time. 

Keep in mind, there are a lot of marketing lingo used by manufacturer's to try to overpromise their refresh rates. Words like 'MotionFlow', 'Clear Action Rate' or 'True Motion' usually mean the refresh rate is half of the number that follows. Example: 'TruMotion 120' is actually a 60Hz refresh rate. 

5) Supports VESA Wall Mounting

While almost every TV you buy new will include a stand in the box, the truth of the matter is a 70-inch model will likely be too large to place on most surfaces in your home.

Due to this, you want to make sure the model you choose is compatible with VESA mounts so you can secure the television to your wall or another area safely.  All of the TV models that I'll recommend below support VESA wall mounting unless otherwise mentioned.

VESA mounts are measured in millimeter sizings. At the 70-inch mark, you'll likely see models offering compatibility with 400 x 400mm mounting hardware, but this may differ slightly depending on the model.

Best 70 Inch 4K TVs 

M70-E3 - 70-inch TV


  • True 120Hz refresh rate
  • Integrated Chromecast
  • HDR10 & Dolby Vision support
  • Works with Google Home


  • Chromecast isn't as user-friendly as dedicated OS
  • SmartCast remote isn't great

VIZIO entered the television market later than most of their competition (2002), but their models have become a popular choice over the last decade. 

The reason for this is that the company prides themselves on offering high-end specs and stylish designs at significantly lower prices than the name brand competition from Sony, LG or Samsung. 

Their M70-E3 is the highest end 70-inch model the company makes, and it packs all the bells and whistles you'd expect. Sporting a true 120Hz refresh rate and support for both HDR10 and Dolby Vision HDR formats, this panel is built to perform. 

On the flip side, there are a few small downsides. The remote design is far from stellar. Additionally, the Smart TV functionality is carried out through its integrated Chromecast. While this option is highly versatile, it lacks the simplicity or general ease of use of a traditional Smart TV OS. 

KD70X690E - Samsung 70 Inch TV


  • HDR10 compatible
  • Remote has dedicated Netflix & YouTube buttons
  • Dynamic Contrast Enhancer makes non-HDR content look better 


  • Only 60Hz refresh rate
  • No Dolby Vision support
  • Rather bulky

The KD70X690E is a television from Sony that packs a native 70-inch display at a price-point well under $2K. The X690E is the lower-end of Sony's 4K Smart TV spectrum yet it is the only series that offers a 70" model. 

While you do get baseline HDR and 4K UHD support in the K70X, you'll need to step up to the X850E series or higher to get advanced features like a 120Hz refresh rate, Sony's Android TV OS or their 4K HDR X1 technology.

If you are set on a 70-inch model, then the KD70X690E might be a good fit. However, if you can jump up or down to a 65" or 75" model, Sony offers a lot more bang for your buck. 

 E70-E3 - VIZIO 70 inch 4K TV


  • HDR10 compatible
  • Remote has dedicated Netflix & YouTube buttons
  • Dynamic Contrast Enhancer makes non-HDR content look better 


  • Only 60Hz refresh rate
  • Chromecast isn't as user-friendly as a dedicated OS  
  • Rather bulky

The E70-E3 from VIZIO is part of their budget line-up. While it offers the most appealing price-point for many consumer households, the specs don't quite live up to the high standards set by their M70-E3. 

At $600 cheaper, you still get a solid 4K UHD panel with HDR10 support. Unfortunately, you'll have to settle for the lower 60Hz refresh rate which is disguised under the marketing term of '180Hz Clear Action Rate'. 

Similar to the M-Series, you'll be able to cast streams from your mobile devices via SmartCast. While I prefer a Chromecast experience over dedicated Smart OS technology, it isn't as beginner friendly especially to less tech-savvy users. 

Solution #2: go big or go home?

As I stated earlier, the amount of 70 inch 4K models is notably slim as manufacturers tend to stick to the 75 inch size when creating a model with a screen this large.

If you are willing and able to make the jump up in both size and in many cases pricing, there are a lot of viable 75 inch models to consider.

I'll name just a few below, but I'll plan to write up a similar style article as this focused entirely on 75 inch 4K TVs in the future if there is enough demand.

75 Inch 4K TV Alternatives

 QN75Q7F - 75" UHD Television


  • HDR10 compatible
  • Harnesses Quantum Dot technology
  • Thin, sleek design


  • Motion Rate 240 really means 120Hz
  • Lacks Dolby Vision support
  • Angled viewing is mediocre

A few years ago at CES, Samsung introduced their SUHD technology which stands for "Super Ultra High Definition." While this term sounds rather gimmicky, the truth is that it is the same 4K UHD resolution just using 'Quantum Dot' panel technology to achieve better contrast and deeper blacks. 

For an in-depth explanation of Quantum Dot technology, you can check out MKBHD's video as he does an excellent job explaining the technology better than I could in text.

The QN75Q7F is Samsung's lowest end 75-inch SUHD TV with their curved model selling for $1k more and their Q9F model priced at a staggering $8k. You'll pay a premium for the Samsung name brand so that plays a role in higher price-point, but this model is gorgeous from an aesthetic viewpoint. 

This models specifications are solid yet the lack of Dolby Vision support is disappointing at this price-point. I also want to make it known that the Motion Rate 240 really only translates to 120Hz which is good, but not as high as 240Hz which the marketing term implies. 

XBR75X900E - 70 inch flat screen


  • HDR10 compatible
  • Runs AndroidTV
  • Works with Amazon Alexa & Google Assistant


  • Base design is a bit odd
  • No Dolby Vision support
  • MotionFlow XR 960 is marketing lingo for 120Hz

Sony has released a large number of 4K TVs for 2017 and their XBR75X900E offers 4K HDR performance at the 75-inch size without breaking the bank.  There are a lot of things to like on this model including the thin design. The base design is a bit odd compared to other 75 inch competitors, and it may be hit or miss with your specific taste.

As you'd expect, this model packs a 4K UHD panel that conforms to the HDR10 standard, but no support for Dolby Vision. Like the previous Samsung model, you do get a 120Hz panel which makes it suitable for handling fast-motion scenes. 

Something that I like about this model is that it offers a true Smart TV experience with Android TV natively integrated. The great part about Android TV is that it works with Google Assistant for voice control via Google Home. Amazon also has certified this model to support Alexa commands which is another cool perk.

75SJ8570 - 70" 4K Television


  • HDR10 & Dolby Vision compatible
  • Runs webOS 3.5
  • Offers Harman Kardon 60W speakers & 20W woofer


  • Oversized base takes up a lot of space (yet stable)

While it is the lowest priced model on for the 75 inch TVs that I mention here, I have found that it packs the most value on the dollar. The design is sleek with slim bezels, a thin profile and oversized base which does take up a lot of table width yet provides excellent stability for the large display.

The technical specs of LG's SJ8570 television are impressive for the price, rocking a 75" IPS display offering 4K UHD resolution at 120Hz. The HDR support covers both HDR10 and Dolby Vision as well as a newer HDTV TV broadcast format dubbed Hybrid Log Gamma (HLG). 

For Smart TV functionality, LG packed this model with webOS 3.5 offering both form and function. Lastly, is the audio performance where Harman Kardon 4.2 Ch. 60W speakers are paired with a 20W subwoofer to offer a crisp native sound output. 

Solution #3: drop down a size & reap the benefits

As I mentioned earlier, the 65 inch screen is one of the most common sizes that manufacturers aim to produce models for. This is primarily due to the practicality of fitting a 65" model the average consumer's home (versus something larger) as well as the general price-point. 

The significant benefit to dropping down from a 70 inch to a 65 inch is that you get a greater variety of models to choose from and since the competition is so fierce in this category, there is a lot more bang for your buck.

65 Inch 4K TV Alternatives

XBR65A1E - 70 Inch OLED TV


  • HDR10 & HLG compatible
  • Runs Android TV​​​
  • OLED panel offers perfect blacks


  • Won't support Dolby Vision until a future update
  • Base design is not for everyone

While Sony hasn't been dominating the television game as of lately, their XBR65A1E puts the company back on the map with highly competitive specs that match or surpass their close rivals. The design is thin and sleek, but the rear stand offers a unique design that not everyone will like (I'm personally not a fan). 

The most notable advantage to their A1E line-up is the OLED support which is more common in 65-inch market than larger screens due to its complexity and higher panel cost. OLED offers the ability to completely turn off its pixels to transmit true blacks. This is unlike LED or LCD which function by simulating black while remaining backlit. 

Beyond the OLED technology, this model ships with Android TV running natively in the backend for full Smart TV capabilities along with support for Google Assistant and Amazon Alexa voice control.

HDR support is native for HDR10 and HLG right out of the box, but they have stated that Dolby Vision support will be coming to this line in the future via a free downloadable software update (no estimation on when).

OLEDC7P - 70" OLED Television


  • HDR10, Dolby Vision & HLG compatible
  • OLED panel offers perfect blacks
  • Runs webOS 3.5
  • Ultra-thin profile 


  • minus-circle
    Integrated speakers aren't that powerful (can be solved with a sound bar)

LG was one of the first major manufacturers to bring OLED panels to their consumer televisions which have put them at the top of the market the last few years. Their C7 OLED line offers a lot of value on the dollar with an ultra-thin design thanks to the lack of a backlight for OLED. 

While you get the perfect blacks from OLED, LG has created this model to perform with integrated webOS 3.5 and support for all HDR formats including HDR10, Dolby Vision and Hybrid Log Gamma. 

Since the screen is so thin, LG didn't decide to integrate any bulky speakers for optimal audio performance. This means you'll only get Dolby Atmos 2.2 Ch 40W speakers (plus a 20W woofer). Fortunately, this can be easily remedied with a sound bar or surround sound system down the road. 

QN65Q7F - Seventy Inch TV review


  • HDR10 compatible
  • Quantum Dot panel offers great contrast & color
  • Thin bezels and attractive base


  • MotionRate 240 is really just 120Hz
  • Lacks Dolby Vision support

Samsung's Quantum Dot technology is back at it again in their QN65Q7F model offering great contrast and color though still falling short when compared to their OLED competition.

The design Samsung chose for their QLED line-up is one of the most attractive with tiny bezels, a thin profile and a sturdy yet elegant base.

With the QN65Q7F, the panel harnesses a 120Hz refresh rate and Samsung's native Smart TV technology which I consider good, but not great. The HDR is lacking with native support offered only suitable for HDR10.
