Regardless of whether you vlogi YouTube, TV streaming Netflix, enjoying a collection of Blu-ray or home video recording with the camera, 1080p is the standard among high-definition video around the world video most of the time. decade. Now, thanks to quantu jumping from 1080p to four times higher resolution video , high definition (HD) goes to the side to make way for ultra high definition (UHD) and its slightly more sophisticated counterpart, 4K.
Despite the fact that the two terms UHD and 4K have become synonymous for many years, UHD remains the highest resolution available today for home use. With a resolution of 3,840 x 2,160 UHD screens really don’t exceed 4000 pixels in a horizontal display 4K with a resolution of 4 096 x 2 160. Despite four times the resolution of your screen 1080p, despite the fact that sold as 4K, UHD, by the way, not even true 4K.
Instead of having to constantly remind people that UHD and 4K divided by 256 horizontal pixels for each of the 2160 vertical pixels (the difference is only 552,960 pixels), the producers decided that it is easier to sell their products as “4K UHD”. And then the question arises: if you want to combine two terms together, why not release a display with a higher resolution? One word: broadcast .
As long as the standard format for television around the world is 16: 9 or 1,78: 1, manufacturers will continue to meet this standard, even if it means sacrificing over half a million pixels in the process. This is because the majority of consumers, even avid movie lovers, browsing on average more television programs than feature films. Not only that, but due to the preference of the Director and the Studio, the proportions of feature films are constantly changing, from 1.89: 1 to 2.76: 1. As a result, black streaks that we see in the upper part iu the bottom of the screen, is inevitable, no matter what their proportions comply with the emission standards in the United States or the standards of Quentin Tarantino .
At the end of the day most people watch more TV than anything else and has no meaning to suffering with black bars at the top and bottom more often than when Hollywood and even more so the entire world film industry, still does not establish a universal standard form factor that can meet the producers.
How can I improve my movie collection?
Imagine that you have one slice of bread and you want to make a sandwich with triple decks. Gonna have to cut this one piece into four, and the fact that you got would be very small, but very high half-sandwich. Now imagine that you have a device that can three times to clone a slice of bread. One piece becomes four, and now you have enough to make a real triple-decker.
This is what makes scaling HD .
Instead of having to make one pixel for four pixels, 4K UHD TVs have built-in motors for zoom HD, which generate additional pixels based on surrounding pixels. A single gray pixel surrounded by black and white pixels becomes four gray pixels, each of which is darker or lighter than the next, depending on its proximity to the black or white surrounding the original.
Moreover, scaling also exacerbates the HD region, where the light and shadow to save, or in some cases to increase the depth of the original image.
However, the image in 1080p resolution massturbate up to 4K UHD is all the same 1080p picture . Just more . The HD conversion does not add and does not disclose any new or previously unseen content. Just allows you to watch HD content on the screen with a resolution 4K UHD, not looking on a thick, black border all the time, and without promising ziarnisto image as if each pixel was four times more than I should.
Where can I find the 4K content?
Although the possibility of improving HD-TV-in-flight of course, the welcome bonus, the real reason for the presence of a huge 50-inch TV with 4K resolution, the ability to view the original 4K content in all its stunning glory.
Unfortunately, as with most new media technologies, 4K TVs are still in limbo, gadget techno-gadżetowego-22: because of the limited materials is limited demand, and because there is limited demand, the content is limited. And so on for as long as manufacturers are gradually leaving the old model and force everyone to buy 4K, or some of the leading manufacturers of the means to produce content, despite the limited number of consumers.
However, thanks to alternative media, by which I mean an alternative to Hollywood, MSNBC, the reality is a little more content in 4K than you would expect.
Shows no signs of slowing down and with full intention to remain in the forefront, like Netflix and Amazon do not only transmit, but produce original series in 4K. Current libraries of both companies, which have a 4K feature films increases only for a month.

Finally, games with 4K quickly becoming affordable.While the number of games designed to support 4K resolution is limited, you can expect more and more, when prices fall, or a video.
