Comparison of 4K UHD vs 1080P Full HD

November 27, 2015

4K technology seems to be on the cusp of taking over the HD digital media world, from TV screens to computer monitors to cameras and projectors, 4K screen resolution and all of its accompanying features are starting to circulate widely. But, you might be wondering, what exactly is 4K and is 4K UHD superior to 1080P or not. If so, read the following pst to learn what are the differences between 4K and 2K.

What Exactly Is 4K?

4K, officially known as UHD (Ultra-High Definition), is an overarching term that encompasses visual resolution technology which offers 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.

Currently, the best display of UHD technology is the 4K resolution TV and many of these have been emerging on the market since mid-2013, although 4K monitors have been around since 2013 and 4K resolution film and photo cameras commercially since at least 2012.

4K display has to consist of at least 3,840 pixels (horizontal) x 2,160 pixels (vertical) of resolution and the horizontal can go above 4,000 pixels. This puts it on the top of the current scale of digital resolutions in which the bottom is occupied by standard definition TV (450X540 pixels), HD with 720 pixels and full HD at 1080p.

In simplest terms, if you measure HD resolution by vertical pixel height (720p, 1080p) then 4K UHD can also be called 2160p.

As you can see, 4K outstrips its best HD predecessor by a very wide margin in creating a resolution profile that’s two times wider and two times higher than 1080 HD, thus giving a total screen resolution that’s 4 times larger overall, thus its name, 4K or, as it used to be called, Quad HD.

4K vs 1080P: in Visual Acuity

The 4k image is smoother, and has more detail than the 1080p image. Look closely and you’ll see that the edges around objects in the 1080p picture are noticeably more jagged. The difference is because the higher pixel count of a 4k screen allows for a more natural representation of the picture, with smoother outlines for distinct objects and added detail in the image.

You see: 1080P is the clear water, and 4K is the crystal clear water.

Winner: 4K UHD

4K vs 1080P: in Video Source

1080P video is widely used almost anywhere, but only very few sources can provide 4k content. Currently, it is only available on some titles on Netflix, YouTube or Sony’s Video Unlimited.

Winner: 1080P

4K vs 1080P: in Device Compatibility

4K Ultra HD video delivers superior viewing experience compared with 1080p video when displayed on devices with 2K display. However, media players and 4K TVs supporting 4K video are more expensive than the traditional ones and only well-equipped computers can play 4K video smoothly. With high resolution, 4K video with large file size may also cause storage problem. While, playing a 1080p video is quite easy and convenient since it is compatible with almost all smart mobile devices, tablets and TVs.
