What’s the Difference Between 4K and UHD?

If you have sat on a fence for new TVs, monitors, or other screen devices online, chances are you have heard to mention “4K” and “UHD,” or ultra high definition – often in the same sentence. Although different, the term 4K and UHD are used alternately to market the phenomenal watch experience on the screen or device such as the projector. 4K more mainstream than before, and advertisements make buying choices for both even more confusing. Therefore it is better to know the difference between 4K and UHD.

4K and UHD have different origins. While UHD is used in the display equipment industry and for broadcasts, 4K is originally used in the context of cinema and video production. Like the Audio Teufel record, UHD TV has fewer pixels horizontally and therefore, cannot reach the same resolution as the 4K TV set. To decipher the difference, let’s destroy it further.

4k vs UHD resolution

The UHD resolution implies 3840 × 2160 pixels (or 8,294,400 pixels in all), which exactly four times the number of pixels that we found in the full HD (1080p) display, according to the Teufel Audio Post which is linked above. Multiplicity is probably the reason UHD must be replaced with 4K easily in general lexicon.

4K, on ​​the other hand, shows a resolution of 4096 × 2160 pixels. Because of this vertical and horizontal pixel settings, the standard is sometimes called 4k2k. 4K has a broader pixelation than UDH because the 4K digital cinema projector must support movies in the “flat” aspect ratio and “scope”, according to the RGB spectrum. Flat configuration has an aspect ratio of 1.85: 1 (which means, for each unit width of the screen, there is 1.85 units in length). Meanwhile, the scope configuration uses aspect ratio 2.39: 1. Therefore, a film in a flat ratio has a typical resolution of 3996 × 2160 pixels while the scope has a resolution of 4096 × 1716 pixels. In a simpler term, the scope is wider but the length is shorter than flat orientation.

The decision between using flats and scope is usually from directors and film producers but we can expect newer films to rely on the scope more than evenly. As recorded by one type of imgur user, the scope is usually used in large-scale epics or action films – with anything related to “The Avengers” becomes an exception.

Should the difference between 4K and UHD influence your choice?

The answer is yes and no. In particular, it depends on how you plan to use your screen. If you buy a TV or special display device to watch movies, you might end up with UHD because that’s the way most TVs from major brands such as Sony are marketed and sold. It might even be difficult to find a TV that supports 4K resolution – finding a PC monitor or projector that supports 4k2k resolution is relatively easier.

If you want to avoid this confusion and buy an adaptive device to all forms of content, then you can easily choose to ignore the nuances and get you like – even if you are labeled as the UHD TV 4k. The result will be the same high-quality resolution and an ultra-modern watch experience.
