One that has gained some headway is Google’s VP9 4K video compression codec, which the company still uses in compressing the 4K content streams found on its You Tube video service.
Most premium 4K TVs today are compatible with both VP9 and H.265, though not all models offer both.
However, in a more specialized context, proper 4K is what is most often found as a digital camera resolution standard that involves an actual 4,096 x 2160 pixel resolution at an aspect ratio of 1.9:1 (horizontal: vertical) as opposed to common TV based 3,840p width and aspect ratios of 16:9 or 1.78:1.
Basically, regardless of the fact that 4K TV is officially defined as UHD, you’re buying into the same thing whether you see either 4K or Ultra HD used to describe a TV, monitor or film/Photo camera.
Now, in terms of TV 4K systems, this resolution isn’t even entirely noticeable unless you enjoy a very large and thus very expensive screen or are sitting abnormally close to your TV.
However, when it comes to projectors, the power offered by 4K really does become visible.
4K film camera prices are dropping too and a lot of new content is being filmed and distributed based on this platform.
Then there are also OLED 4K TV displays, which also exist for Full HD TV models but offer particularly spectacular picture quality and precision illumination in 4K UHD OLED TV models.
If what you’re looking for is maximal image quality features –even if you don’t particularly care about 4K UHD resolution itself—the major 4K lines of TVs from major manufacturers also happen to offer the top of the line in terms of these other image enhancement capabilities and they offer them at prices that are steadily dropping to the point that they have now reached prices on par with those of many higher-end HD TVs.
Well, we’re going to cover exactly that here and give you an overview of all the critical information about 4K ultra-high definition and other types of ultra HD resolution that you need to know as a potential buyer of TV, projector, camera and other display or recording technologies. 4K, most commonly known by its UHD (Ultra-High Definition) variant for TV and PC displays, is an overarching term that also encompasses several resolution sizes which offer more pixels than regular HDTV (at least 4 times more pixels and thus the name 4K).
The ultimate result of this increased pixel breakdown is a an image clarity that goes well beyond conventional 1080 pixel HD resolution and presents more vibrant, varied and realistic colors as well as much higher frame rates.
