what is Ultra HD 4K TV


In 4K TVs, 4K Ultra HD by Matt Bronowicz11 Comments



We are constantly updating our site  (www.4Kadvice.com) because of how fast technology is moving.  Especially when it comes to 4K Television technology.

We created this site several years ago because we saw the need to educate people about 4K, so that they can make informed purchase decisions.

We did this based on the fact, that in 2014 we could not find any helpful information about 4K when we went online searching.  We were intrigued by 4K TVs, which had just come on the market. 

We heard a bit here and there, but really had no idea what 4K was or what it meant.

Was it an expensive ‘toy’ that rich people bought?  Was it some kind of exotic technology device that would always remain too costly for the general public to buy?  We had many questions, but found nothing online.

Thus, 4KADVICE.com was born.

Cheap 4K TV

Ever since, we have dedicated our time and energy to delivering quality articles and helpful information to anyone interested in TV watching technology and/or cameras.

What attracted us most, was the idea of a TV that makes ‘television watching’ far, far better than it already was.  Could this be possible we thought?

Most people thought that we would never see a better picture image than what High Definition brought to us around year 2000.  The world changed when we began handing Flat Panel HD TVs on our walls and over the fire place.   

Best of all the picture was crisp & clear….a major, major step-up from what we were all watching before  (SD- Standard Definition).  UHD 4K TV

Not only did we want to educate the public about 4K, but we have to always get it right.  We have to deliver to you the most accurate and up-to-date information that we possibly can. 

This means, tweaking and changing our articles and Posts along the way.

But, we are happy to do it, because this is the entire point of our website www.4kadvice.com.   Please help us further by sharing this site and its Posts with your friends and family. 

The more people we can educate, the better.

Now, let’s begin with the basics for all those of you who need them.  And, apparently that is a lot of you.  Experts say that only about 25% of households have upgraded to 4K TVs. 

The rest do not even know what 4K means.

4K Ultra HD TV


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.

4K Ultra HD TV

***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.

4K Ultra HD TV

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”.

We always recommend that you shop on Amazon.com.  They have the greatest selection of 4K Ultra HD TVs and at the lowest overall prices. 

We saved $360 bucks when we bought our first Sony 65-inch 4K UHD TV on Amazon.  It was conveniently delivered within 2 days and shipping was FREE & guaranteed to be safe. 

Convenience was a big factor to us because our lives are so busy. 

We don’t have time to go into the store and deal with all those annoying pesky sales people trying to sell you things you don’t want or need.

  1. We love our Sony 4K Ultra HD TV that we bought off Amazon back in 2014. We saved more than $400 at the time compared to what we would have paid in the store at Best Buy.

    Amazon really does have the best deals. Go and look and touch any 4K TV you might want to buy. Watch it, test it, etc. Then come home and get online to Amazon and buy the same 4K TV for hundreds of dollars less, FREE shipping that is guaranteed for safe delivery FAST (ours came within 2 days right to our front door).

    Good Luck!, MB

  2. We’re in the process of remodeling our basement, and my husband wants a large 4K TV that’s at least 65″. I didn’t really think we needed to go with a 4K, but I can see from your article that they are the top quality ones out there right now.

    Is there a particular brand or brands that you would recommend over others on the market?

      Hello Janelle, thanks for coming to our site http://www.4kadvice.com and supporting us via your comment.

      Great question about 4K TV…..Well, Sony was the first to pioneer the 4K Tech.  We own a Sony 65-inch 4K TV and we paid top dollar in 2014 when this 4k tech was very new  ($2,900).  But, do not worry now because this same sony TV today is only about $1,200.

      Prices are way, way down on 4K TVs…any of them.

      As a matter of fact, 4K TV prices are exactly equal to those of a new 1080 HD TV.  4K TVs have been on shelves for nearly 5 years now giving them plenty of time to drop the price.

      It makes no sense to buy another 1080 HD TV today since you can buy or upgrade to a new 4K TV for the same price as buying a new 1080 HD TV.

      This is because 4K TVs are replacing 1080 HD TVs entirely, but it is happening slowly.

      You may see a great deal here or there for a new 1080 HD TV as merchants get rid of stock.

      Also, all the broadcasting and movies and TVs shows are now producing using 4K resolution cameras systems.  This is what gives us Real, or Native True 4K content….when they use 4K cameras.

      For example, Netflix and Amazon Video have been producing their own TV shows…and they are very good.  They have over 150 of them combined.  MOST OF THEM were recorded in 4K, but you can also watch in 1080 HD obviously.

      We are moving in that direction, so it only makes sense to buy a 4K TV.  Not a curved one either…those are just for show.

      Your husband is probably loving me right now, knowing that you read our articles.  But, I am being honest.  Do not make the mistake of buying another 1080 HD TV.

      Get a Sony, Vizio or Samsung 4K Ultra HD TV that will automatically come with HDR- high dynamic range with has to do with the color.  These 4K TVs give you such an amazing picture image that it looks SO REAL and so True-to-Life that its like you are right there live on the scene of the set.  No joke.

      thats if you watch a real, or native 4K content and NOT something that has just been upscaled from 1080 HD to close to “4K” resolution. MOre on that within the links I give you below. Thanks and please use our Amazon links.  Amazon is the best place to buy a new 4K TV. We bought our Sony on Amazon 65-inch and saved us $400 compared to going into the store.    –Matt B.

      HDR…..EXPLAINED: This Is Another Reason Why You Should Upgrade To 4K


  3. I guess I’m behind the times when it comes to TVs! I had no idea what 4K was before reading your article so thank you for educating me. Do you think it’s only for avid movie watchers? We live in the mountains and only have satellite TV and do not stream via the internet because we pay that by the gig. Needless to say we just watch mostly shows. Have many actual channels converted to 4K? Will they in the near future? If it’s going to be awhile, would it be beneficial with just a satellite service?

      Hi Lisa!

      Thanks for reading our post and commenting.  We do appreciate it!  Our goal has always been to educate people about 4K televisions and other 4K devices.

      You ask some amazing questions that many others need and want to know also.

      First, I LOVE the mountains.  My heart has always been in the mountains.  I lived in Vail and then Crested Butte CO, and then Jackson Hole as well.  Most of all, I loved in Switzerland while going to school and I skied many mountains there.  It was wonderful.

      Although, we recently moved to the beaches of Destin Florida, during the winter ski season we will live in Driggs Idaho near Grand Targhee resort and J hole.  My wife won over us living on the beach as long as she agreed to live in the mountains during the ski / snowboard season.  So, it works well for us!

      Boy, I am far off track with your comment and my reply. Sorry.

      As far as 4K Ultra High Defintion Televisions go, you are not alone in not knowing mich about them.  I have come to realize that most consumers are unaware or mis-informed about 4K.  For example, many people think 4K tvs are some exotic technology or toy only for the rich.

      But, the fact is that 4K resolution TVs are simply replacing HDTVs, just like HD TVs replaced SD- Standard Definition TVs back around 2001.  We went from those ugly, big box tube TVs that we all had from the 50’s up to year 2000ish at which point we started buying and highly enjoying flat panel HD TVs that you could hang on your wall or.over the fire place.

      Anyhow, 4K TVs still look the same as a glat.panel HD tV like you currently watch and own now.  The biggest difference is that 4K resolution TVs have way more pixels (about 3,800) which is FOUR times as many as your current 1080 hd tv has.  This means the picture and movies that you watch are four times more clesr and real looking than what you currently watch.  They really are amazing to watch (4K tvs). Check out a demo next time you are near an electronics store.

      I totally understand why you dont watch much TV.  In the mountains, you have so, so many more fun activities to do than a place without mountains.  You dont want to be inside when you can be hiking up a 14K foot peak.

      Same reason why we live.on the beach, many more activities to do like swimming, boating, etc.

      But, i loce watching good TV shows and Movies. I also love streaming good series.  I like technology in general so i hopped on the train when 4K TVs first came out because I was blown away at how true to life the picture image was when i first saw a demo.  It looked so real!!

      We nearly lost our home in this recent Hurricane.  We live 10 mins away from mexic9 beach that got slaughtered. So sad. We had major damage to our beach home, bit it was not destroyed thank God.  We have no power, cell or internet.  I drive an hour West to get internet and work online.

      I say all this to let you knkw that we have Satellite TV as well.  Because we are not close enough for cable.  After this storm our power was on for a short time and we had TV.  Sat has its benefits because others with cable TV dont have it bc their lines and buildings were wiped out in the storm.

      I stream 4K movies and TV shows on NETFLIX right through my Dish sat. You do need an internet connection to do that, but if you cannot get CABLE internet they now have internet service directly through a Dish Satellite.  And, the speed is improving fast

      I watch NETFLIX and HULU in 4k.

      There are only a few 4K channells and networks right now, bit they will be added soon for sure.

      Eventually, everything will switch over to 4K.  Most TVs nowadays that are sold are 4K Ultra HD TVs if you look at ads.

      It makes no sense to buy another HD TV today because prices on 4K TVs are the same as prices on any 1080 HD flat panel TV.  4K prices have come way down since 2014 when 4K tvs first came out.  I bought my Sony 4K in 2014 for.$2,900 because it was brand new tech.  Today, in Amazon, my same exact TV Sony 65 unch 4K TV goes for only $1,180. Way cheaper.

      So, next time you go to upgrade or buy abother TV…it will be a 4K UHD TV because the entire tv industry and tech has been updating to this mew technology

        And you will LOVE it!  Movies look real, people look like they are standing in your family soon their faces are so clear and real!

      Since you are not big TV watchers, I would not rush to buy a 4K TV until your TV breaks or becomes too old.

      But, if you do want to improve your movie watching experience, then you can buy a new and very affordable 4K UHD TV today on Amazon.  You can get a big 55 inch 4K UHD HDR TV in Amazon new for $500 these days.

      It will be a while before networks go to 4K.  Right now only a few are putting out 4K movies or series events every now and then. There are sporting events and other shows being broadcast in 4K, but its all jist starting to happenIt will be years before the majority of network TV goes to 4K from 1080i HD.  However, 95% of all movies and shows (like Netflix and Amazon produced tv series original) are being filmed using 4K resolution cameras.  You can still watch thsm in 1080, but only benefit from it being filmed in 4K if you have a 4K tv obviously.

      For now, if i were you i would wait a while.  I hope this helps you! Take care and thanks for taking the time to comment about our post. –Matt

  4. This one is definitely new to me I have never heard of 4K before this. So let me see if I am understanding this right. This a new TV with even better resolutions than the Hi Def? And I seen where you said this is becoming more well know and becoming more popular. So how long do you think it will be when this will become the new thing?

      Hi Melissa, great questions and thank you for visiting our informational site at http://www.4kadvice.com.

      First off, 4K ultra HD Televisions are really the ‘new thing’ right now.  They are really not so new either.  They have been on shelves for over 5 years now.

      We do not know why consumers have not jumped onto buying these TVs in the masses.  It has been more slower than when HD took over SD with flat panel TVs.

      I suppose it is because 4K UHD TV look the exact same as any 1080 HD Flat Panel TV.  The main difference is ‘Under The Hood’, if you will.  The tech inside a 4K TV is absolutely amazing.

      You are correct in that Sony took a 1080 HD pixel display and figured out how to squeeze FOUR more tiny pixels within the size of what is equal to only ONE pixel in the resolution of any 1080 HD TV.

      This means that it gives the picture image FOUR more times the (data and information) like sharpness, color, contrast, depth, clearness, etc.  4K TV are for sure FOUR times better within the picture image while you are watching more than any 1080 HD Picture image.

      WHo would have ever thought that we would see something better than 1080i High Definition?!  Maybe people are in shock?

      Secondly, as with all new tech the price of a new 4K Ultra HD TV back in 2013 and 2014 was more than TWICE the price that it is now. It was super expensive.  Perhaps consumers think 4K TVs are still super expensive.

      They are NOT.  Today, they are priced the exact same as any new 1080 HD TV.  And, 4K TVs are totally replacing 1080 HD TVs…slowly but surely.  If you look at electronics stores and places like Walmart or BestBUy they are ALL marketing and advertising mainly 4K UHD Televisions and not trying to sell 1080 HD TV much anymore.

      Hope this helps and please come visit us again.  Some more helpful posts below. – Matt B.

      4K TIPS AND TERMS (revisited)


  5. Matt,

    I wish I had found your site a few years back when I bought my Samsung UHD 60 inch TV. At the time, I wanted to upgrade from 1080p to 4K since I thought I was getting four times the pixels. However, I didn’t know that UHD was not true 4K at the time, so I purchased the 2160 pixel UHD TV. Thanks for educating everyone so they don’t make the same mistake I did!

      Oh well Tony…you live and you learn.  To compare, I made a similar mistake.  I got hasty and bought a Sony 4K 65-inch TV back in late 2014 and paid $2,950 for it!  Today, this same exact Sony 4K with HDR…is selling for only $1,200 on Amazon.  If I had waited just another year I could have saved over $1,500 bucks!

      Plus, I dont have HDR.  My TV came before HDR was standard on all 4K TVs.  H DR as you know involved color.  Nowadays, producers can match any color when they film or reproduce, Prior to HDR they were limited.

      So what HDR does is allow the picture image on a 4K TV to look that much more real and true-to-life.

      Luckily for you prices have dropped bigtime.  Now, 4K TV prices are equal to 1080 HD TV prices.

      Try selling your TV and getting some money back.  If you bought it on Amazon they have an awesome trade back program.  If you can get a few hundred then go and buy the TCL 55-inch 4K HDR TV for under $500 on Amazon and you will be back in shape!  – Matt B.

      HDR…..EXPLAINED: This Is Another Reason Why You Should Upgrade To 4K

  6. Thanks Mat. I have to admit, I was one of those who was a little unsure what 4K referred to. HD / HD Ready / $4K HD. Manufacturers float these terms as though everyone knows what they mean. (Am I the only one who just wants the best bang for my buck?)
    Have you done a review on curved screens? Whether or not they are worth the extra money?

    1. Author

      HAPPYB!!  Thank you for visiting our site and taking the time to comment. We do really appreciate your interest in 4K.  We hope our article was helpful and educational…it seems like it was.

      You are NOT alone whatsoever.  You along with MOST other consumers  (75% of all households) do not know what “4K” is or what it means.  Not sure why, because 4K Ultra HD TVs have been on shelves now for over 5 years.

      Their price started super high like all new technology.  For example, in 2014 I saw a demo of a 4K TV and got hasty.  I just had to have one.  So, I paid $2,900 for a Sony 65-inch 4K TV.

      Today, the same exact 65-inch Sony 4K TV is selling for $1,289 on Amazon.  That is more than HALF LESS than what I paid.

      The good news is that 4K TV prices are way down across the board today.  4K TVs are priced the same as 1080 HD TV are because manufacturers want consumers upgrading to 4K and not buying another 1080 HD since HD has been available now for 17 years.  4K is replacing 1080 HD, just like HD replaced SD- Standard Definition back around year 2000.  That was when we started buying those flat panel High Def TVs.

      Regarding Curved, I am placing a link to a great article I researched and wrote about curved.  In a nutshell, they are a lot more expensive (whether its 1080 HD or 4K) and they cool really cool and impressive.  They look awesome!

      However, aside from looking extra nice..they really do not serve any additional technical benefit.  If it were me, I would take the extra money and instead buy a larger 4K TV display rather than spend it on a curved.

      Hope this helps, Please share our site.  thanks, matt b.
