• What Does 4K TV Mean? Where Is The Ultra High Definition Television Industry Headed?

Back In The Day

Until recently, high definition or 1080p (1,920 by 1,080) resolution was the standard in large TV formats.   HDtv is quickly being replaced by ultra high definition TV, commonly called 4K. The term "4K" is generic and refers to a resolution with a horizontal pixel count of around 4,000.

3840 by 2160, or “2160p”, has become the dominant resolution used in the consumer market when defining 4K.  Currently a product must have this minimum resolution to qualify.

Is 4K Better Than HDtv?

Yes!  4K is a greatly improved display, especially on larger screens.  In fact, it’s four times better! Four times the number of pixels as the older HD standard...

1920 X 1080 = 2,073,600 Pixels Or About 2 Megapixels

3840 X 2160 = 8,294,400 Pixels Or About 8 Megapixels

4K is obviously much sharper than 1080p

Some Of The Disadvantages Of 4K Resolution

  • Huge file sizes.  Every frame of 4K video contains four times the information.
  • A delivery problem.  Larger video files require higher bandwidth and more storage.
  • 4K is expensive.  There are still older HD televisions on the market with plenty of pixels for most consumers at a fraction of the cost.

Where Is All This Going?

Amazon, YouTube, and most of the streaming TV industry have adopted the 3840 × 2160 resolution as their 4K standard and offer content.

4K is just the beginning!  Ultra HD resolution can refer to resolutions ABOVE the 4K standard.  Resolutions as high as 8K!

With larger screen sizes there is a need for more pixels.  UHD TVs mean more pixels so larger TVs and projectors are possible.  One feeds the other, and there is no slowing down!
