4k UHD
At present, introduction of 4k(ultra HD) is the succeeding footstep of advancement in HD Technology.And if you are the person who prefers to be mad about the information of very up-to-the-minute and with all the newest features, there is no doubt that you are familiar with next technological milestone 4K resolution supported HD TVs and displays. However, it is true that like other most of the next generation technology, 4K solution is not out of problem of lacking initial support.

What is 4K UHD?

Generally, when we are going to talk about 4K UHD, the first things come into our mind is high definition television. And yes, it is, as there are two ultra-high definition resolutions television: 4K UHD & 8K UHD. However, now 4K is chosen officially for consumer products as Ultra HD or Ultra High Definition. Technically, a resolution of 3840 pixels × 2160 pixels (8.3 megapixels) is considered as 4K UHD. 4K UHD is horizontally and vertically two times of resolution of the 1080p HDTV format and four times of 1920 × 1080 (2.1 megapixels).4K resolution is gradually in a little while employed commercially in digital cinema projection and home theatre environment as well.

Does 4 Times Resolution of TV Mean 4 Times Surprise?


One question may come into mind, when we consider the resolution of tvs, that bigger is better? Recently, the market is flooded with big, beautiful, and monster sized Ultra HD TVs such as Sony’s 84-inch 84X9005, LG’s 84-inch 84LM960V, Panasonic 152-inch TH-152UX1W, and 84-inch Toshiba 84 L 9300.

Though the higher resolution of TV is expected, people think that four times pixel does not vary the quality of picture and being worthy of excess price. And it is appreciable that now the ultra-high definition tvs is getting smaller and more reasonable. 58-inch Toshiba 58L9300, 65-inch Toshiba 65L9300, 55-inch Sony KD-55X9000A and 65-inch Sony KD-65X9000A are the names of  some of small sized 4k HD Tvs.

At the time of releasing 55-inch and 65-inch models of Sony to Australia, Hass Mahdi, Sony Australia.Home Entertainment Marketing Manager, said that these TVs are about “making 4K resolution a reality for everyday consumers.”  Truly, 4k Ultra High-Definition, day by day increases beauty of living room with the diversity of content options for consumers besides better video and sound quality.

34K UHD Serves You a Lot!

Digital cinematography has encouraged to shooting at a resolution of 4K. Ultra HD content is by now available in the vaults of cinema enthusiasts of the Hollywood. For distributing and restoring of commercial projects, movies are now shooted in Ultra HD and mastered at 4K resolution. 4K-capable F65 camera Sony for example is commonly used in film and dramas of TV such as Made in Jersey, Justified, Save Me as said by The Hollywood Reporter. Indeed, Ultra HD Blu-ray discs need to see picture of high quality as well.  Sony S5100 and Samsung BD-F7500 machines are so-called 4K- Blu-ray players.Photographers are more enthusiastic to get the benefit from ultra HD technology. Moreover, Sony moves up a gear for internet movie service of 4k ultra HD. Moreover, 4k Ultra HD monitors become more useful to serious gamers, video editor as well as graphic designers.

4K UHD plagued with Glitches!

4K Ultra HD is still expensive display and the creation and distribution of content for such display is also difficulty because it is costly and  there is a great amount of information filled into 4K video. Though 4k ultra high definition TVs, projectors, screens still use in home as well as Professional movie theaters, I can see people going to 8k UHD TV(7680×4320-pixel resolution) which delivers greater definition and 4 times resolution of current HD TVs.
