There are also computer screens with unique resolutions such as 5K (5,120 x 2,880) or ultra-wide aspect ratios of 21:9 with crazy resolutions such as 3,440 x 1,440. There are so many variations that we couldn`t hope to cover them all. Will the extra resolution offered by 4K make movies better? One could say that it depends on the format of the original film. For example, “The Blair Witch Project” and “28 Days Later” were both shot using standard definition camcorders, and there would probably be few additional benefits to buying either of the two movies in a native 4K format via a DVD – depending on the quality of the scaler in your brand new 4K display, Of course. “There has been a huge and noticeable leap from standard definition to HD, but the difference between 1080p and 4K is not as pronounced,” said researcher Dave Lamb of 3M Laboratories. He added that “4K is at the point where the return is decreasing,” but said there could be benefits for screens over 55 inches. Despite the existence of HD and 4K, many TV programs, online videos and all DVDs are still presented in standard resolution, loosely defined as 480 lines. Standard Definition started as NTSC TV shows before going digital with the introduction of ATSC in 2007. The additional resolution of 4K offers better definition and clarity.

4K TV is especially effective on very large screens – ideally, you`d settle for a 55-inch set or even larger. You can get 4K TVs up to 40 inches, which allows you to sit even closer to the screen. Nowadays, it`s hard not to find a 4K TV when buying a new set. UHD TVs, which are now the dominant standard for high-resolution viewing, are available in a range of sizes, with a variety of features and other add-ons to enhance the experience. As 8K TVs gain traction (with 16K models not too far away), 4K TVs are what you need to maximize the performance of today`s HD components. We`re talking about things like gaming systems, Blu-ray players, and streaming media platforms. While 4K is relatively new, high definition (HD) itself has been with us for about a decade and is the format used in Blu-ray movies and HD shows. There are three major versions of HD: Full High Definition 1080p (progressive), 1080i (Interlaced) and 720p (also simply called “High Definition”). The Consumer Electronics Association announced on the 17th. October 2012 announced that “Ultra High Definition” or “Ultra HD” will be used for screens with an aspect ratio of 16:9 or higher and at least one digital input capable of transmitting and displaying native videos with a minimum resolution of 3840 × 2160. [5] [6] In 2015, the Ultra HD Forum was launched to bring together the end-to-end video production ecosystem to ensure interoperability and create industry guidelines to accelerate the adoption of ultra-high definition television.

From just 30 in Q3 2015, the forum published a list of up to 55 commercial services available worldwide that offer 4K resolution. [7] Ultra high definition television (also known as Ultra HD, Ultra HD, UHDTV, UHD, and Super Hi-Vision television) now includes 4K UHD and 8K UHD, two digital video formats with an aspect ratio of 16:9. These were first proposed by NHK`s scientific and technological research laboratories, then defined and approved by the International Telecommunication Union (ITU). [1] [2] [3] [4] It is a standard for digital television (DTV) and the successor to high-definition television (HDTV), which in turn succeeded high-definition television (HDTV). Ultra high definition television is also known as Ultra HD, UHD, UHDTV and 4K. [13] [14] [15] [16] [17] In Japan, 8K HDTV will be known as Super Hi-Vision because Hi-Vision was the term used for HDTV in Japan. [18] [19] In the consumer electronics market, companies previously only used the term 4K at CES 2012, but this changed to “Ultra HD” at CES 2013. [16] [17] “Ultra HD” was chosen by the Consumer Electronics Association after extensive consumer research, as the term also came to the fore with the introduction of “Ultra HD Blu-ray.” [20] On April 2, 2016, the ultra-high definition demonstration TV channel UHD1 broadcast ballet Le Corsaire in Ultra HD live from the Vienna State Opera.
