High definition was first announced in the 1990s, modernizing picture clarity and entirely changing the way that users consume digital content. Ultra-high-definition television companies create revolutionary products that users will purchase for the ultimate viewing experience.
The Ultra High-Definition term was introduced by the Consumer Electronics Association in 2012 to categorize displays with an aspect ratio of 16:9 and a digital input capable of delivering content with a minimum resolution of 3,840 by 2,160. Ultra-high-definition television (UHDTV) is a display feature on digital televisions to produce high-resolution content. There are specific pixel requirements that make UHDTVs 4k or 8k.
4K Ultra HD is not the same thing as 4K; 4K originally described Digital Cinema (4,096 x 2,160 pixels), which is currently not available for every user. An example that uses 4K is an average Blue-Ray disc, mastered in 4K format, which is compatible for Full HD viewing. The quality of Ultra 4K surpasses the regular 4K format.
The horizontal screen resolution display has 4,000 pixels (4K UHD) or 8,000 pixels (8K UHD). A 4K UHD denotes a specific display resolution of 4,096 by 2,160, whereas an 8K display has 7,680 horizontal pixels and 4,320 vertical pixels. A total of 33,177,600 pixels/33.2 megapixels are tallied in the 8K display. The 4K display has four times the amount of pixels than your standard high-definition television (HDTV).

The 8K UHDTV has approximately 16 times more pixels than a normal HDTV (1,920 x 1,080). These two digital setups were invented by the NHK Science and Technology Research Laboratories and approved by the International Telecommunications Union.
Many TV shows and movies are not yet being broadcasted in UltraHD. The marketing of this fairly recent technology will pave the way for eventual on-air UHDTV broadcasting, internet streaming, and cable/satellite systems.
You can literally see the difference between Ultra HD TVs and 1080p TVs. The UHDTV products will have more detail and less visible pixilation. Viewers will see smoother-edged images with greater depth, making the images nearly appear to be in 3D. With this innovation, viewers can sit closer to the screen, which will be ideal for movie lovers who view content on large screens in small spaces.
In “U.S. Consumer Electronics Sales and Forecast July 2013” report, CEA projected Ultra HD shipments to reach 57,000 units, and shipment revenue to earn $314 million in 2013. Ultra HD shipments are expected to exceed the 1 million unit mark in 2015, the anticipated year where more Ultra HD products will be released.
In a statement, CEA president and CEO Gary Shapiro said that “Ultra HD promises to be the next big video product driving change in content, cameras, security, retailing, displays, and even audio. It will drive growth across the entire consumer technology ecosystem.”

It is interesting to consider that without Upscaling technology, Micro Dimming Ultimate Technology, Clear Motion Rate Technology, and Color Depth Advancements, Ultra HD TV would not exist.
Upscaling Technology converts video signals from a lower-quality version, reproducing them to the format suitable for a high-definition TV. This process includes cropping and stretching of content to fit the constraints of the screen. Users can have a choice of scaling. With the invention of High Efficiency Video Coding or HVEC, UHD distribution will have a broader outreach for transmissions.
Micro Dimming Ultimate Technology uses an LCD panel that is adjusts the brightness of the on-screen colors, making the screen never fully dark. This technology will provide UHD devices with vivid and total clarity of images. The UHDTV screen is divided into zones; on an 85-inch UHDTV screen, 1,152 LED zones are present to change the images, alter the color and detail.
Clear Motion Rate Technology monitors the images you see per second of the program you’re watching. It creates a difference when watching high-speed images on your screen, and prevents images from blurring.
Color Depth Advancements give UHD TVs to adopt a wider range of colors. Products like Samsung’s line of UHDTVs can duplicate up to 1 billion colors.
With more than a rainbow of colors, color gradients are less noticeable. UHD panels have up to 8 million pixels on the display. Each panel automatically adjusts the color and brightness of each pixel to make the on-screen images appear realistic.
In a statement, Samsungpredicted that UHDTVs will become the norm for content streams in 2017. Some Ultra HD Televisions from companies like Samsung and Sony are currently available at the staggering price of $3998.00.
