4K resolution, also called 4K, refers to a horizontal resolution on the order of 4,000 pixels and vertical resolution on the order of 2,000 pixels.  Several 4K resolutions exist in the fields of digital television and digital cinematography.  In the movie projection industry, Digital Cinema Initiatives is the dominant 4K standard.  

In television and consumer media, 4K UHD or UHD-1 is the dominant 4K standard.  Most manufacturers today print the label of 4K UHD on TV boxes for sale.   By 2015, 4K television market share had increased greatly as prices fell dramatically during 2014 and 2015.  By 2025, more than half of US households are expected to have a 4K-capable TV (3,840), which would be a much faster adoption rate than that of FullHD (1080p).  Basically, 4K UHD is FOUR times better picture quality than 1080HD….and it shows!  What is HDR

The name “4K resolution” refers to a horizontal resolution of approximately 4,000 pixels  (its actually 3,840 rounded up to 4,000 or 4K).  The use of width to characterize the overall resolution marks a switch from previous television standards such as 480i and 1080p, which categorize media according to its vertical dimension.  

Using that same convention, 4K UHD would be named 2160p.  (and 3,840 horizontal or rounded up to 4k).  It is clear that many changed have taken place with respect to what is called what concerning 4K.  Is it 4K or 4K Ultra HD?  The latest in 2016 is that merchants are calling 4K in general “4K UHD”.  These TVs must meet minimum specifications.

There are two main 4K resolution standards:

  • The DCI 4K resolution standard, which has a resolution of 4096 × 2160 pixels (256:135, approximately a 1.9:1 aspect ratio). This standard is widely respected by the film and video production industry.   The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K.
  • ***UHD-1, or ultra-high-definition television (UHDTV), is the 4K standard for television and computer monitors. UHD-1 is also called 2160p since it has twice the horizontal and vertical resolution of 1080p.  It has a resolution of 3840 × 2160 (16:9, or approximately a 1.78:1 aspect ratio).  UHD-1 is used in consumer television and other media, e.g. video games.

***NOTE:   UHD, or Ultra High Definition is what consumers are purchasing today when it comes to the 4K UHD market.  This is the standard for 4K now.

Many manufacturers may advertise their products as UHD 4K, or simply 4K, when the term 4K is traditionally reserved for the cinematic, DCI resolution.   This often causes great confusion among consumers.  We will try to differentiate these in our.

YouTube and the television industry have adopted UHD-1 as their 4K standard, and UHD-2 for NHK/BBC R&D’s 7680×4320 pixel UHDTV 2 with their basic parameter set is defined by the ITU BT.2020 standard.  As of 2014, 4K content from major broadcasters remained limited.   On April 11, 2013, Bulb TV created by Canadian serial entrepreneur Evan Kosiner became the first broadcaster to provide a 4K linear channel and VOD content to cable and satellite companies in North America.   

The channel is licensed by the Canadian Radio-Television and Telecommunications Commission to provide educational content.  This is probably way more technical information than you were looking for, but its historical.  Our goal at 4KADVICE is to educate consumers and help you make convenient and informed decisions right from our website.

However, 4K content is becoming more widely available online including:   YouTube, Netflix and Amazon.  By 2013, some UHDTV models were available to general consumers in the range of US$600.  As of 2015, prices on smaller computer and television panels had dropped below US$400.  DVB expects UHD-1 Phase 2 services to be introduced by broadcasters from 2017, with features such as High Dynamic Range (using HLG and PQ at 10 or 12 bits), Wide Color Gamut (BT. 2020/2100 colorimetry), and High Frame Rate (up to 120 Hz).

And in 2016, prices for 4K UHD television sets had plummeted!  The cost to purchase your first 4K UHD TV is very reasonable now and we see no reason for consumers to wait.  4Kadvice

Much of this might not mean anything to you.  We agree, the history of 4K may be boring, but at least you now know where it came from.

Youtube began supporting 4K uploads in 2010.  The projection of movies in 4K resolution at movie theaters began in 2011.  Sony began offering 4K projectors back in 2004 in the commercial industry.  It was not until 2012, that Sony offered its first home theater projector for sale nation-wide.  Of course, at the time it was very costly (several thousand dollars).  

4K Projectors were manufactured and sold before 4K UHD Televisions.  It is safe to assume that SONY first pioneered and then dominated the 4K TV market.

Major sales of 4K TVs began in 2014.  The founder of this site 4KADVICE purchased his first SONY 65-inch 4K TV in 2014.  Without much information online at that time, he was on his own as far as collecting research and learning all there was to know about this new 4K technology.  Making an informed decision on which 4K UHD TV set to purchase was limited.  

This is precisely why 4KADVICE was created.  To give consumers a direct link to accurate and current information, as well as presenting the best prices and deals to readers of the site.

However, what good is a 4K television without 4K content to watch?  Not much.  So, in 2014 Amazon Studios ‘saw the light’ and begn shooting full length original TV series and new pilots mastered in 4K.  This was welcome news to all those people who dared purchase some of the first 4K televisions.  YES, I was one of those people.  I bought my first 4K SONY TV in 2014.

In 2014, NETFLIX began streaming “House of Cards” and “Breaking Bad” as well as numerous nature documentaries in 4K.  This too, was great news to 4K TV owners.

Today, we have numerous sources to watch and stream 4K content from.  Youtube, Netflix, Amazon Instant Video, Sony and many other networks now offer plenty of 4K content.  More than ever before companies are mastering films in 4K as original.  These are the absolute best programs to watch with the best picture on your 4K device.

Another technological update to televisions is ‘upconverting’.  This basically means that the TV has the capability to take a film mastered in 1080p and convert it up to a higher pixel amount.  This is upconverting.  The picture is not as quality as a 4K mastered (or native) film, but it is much better than 1080pHD.  

The number of pixels is in between 1,080 and 4,000 depending on the specific TV model you own.  Some do better at upconverting than others.  This is definitely a feature that you want to consider when purchasing a new 4K TV.  Look for our Posts related “upconverting” to learn more.  All of our future reviews on 4K products will include notations concerning its upconverting ability.  This is also known as “upscaling”.
