2K is a general term that refers to a resolution level where a screen or content has a horizontal resolution of approximately 2000 pixels. Because the 16:9 ratio is the international standard for high-definition video specifications, the common format of 2K resolution in video production, display and other fields is 2560×1440 (16:9) (WQHD).

Therefore, a 2K screen refers to a screen with a resolution of 2560*1440. The fineness and saturation are much higher than that of a 1080P screen, and the display effect is clearer.

#The concept of 2K screen is not intuitive. In fact, it starts with the once popular 4K TV. Hollywood film producers have released a new digital movie resolution. According to different ratios, when the horizontal coordinate resolution is around 4000 points, it is called the 4K standard. The typical case is a 16:9 aspect ratio. The coordinates are 2160 points, so a standard 4K monitor has a 3840×2160 resolution of 8 million pixels, while the 2K resolution is only about half that, which is a 2560×1440 resolution (of course this is in the case of 16:9 said).

The so-called 2K is just a general term. It does not mean that the horizontal resolution is really only 2000. The International Communications Union stipulates that the standard resolution of 4K screens is 3840×2160, and the standard resolution of 2K screens is 2560×1440. The familiar 1080P resolution is 1920×1080, which is 1.9K, and the 720P resolution is 1280×720. The resolution is 1.3K.

##Comparison of 2K resolution and 1080P

The resolution of 1080p (Full HD or FHD) is 1920x1080. Although it has a horizontal resolution of nearly 2000 pixels, in most The media, including web page production, video production, books, etc., consider 1080p and 2K resolutions to be different resolutions rather than the same.

According to DCI official reference materials, DCI and related industry standards do not regard 1080p as 2K and 4K resolutions.

Although 1080p is not standard 2K, because 1080p has a horizontal resolution of nearly 2000 pixels, 1080p can be classified as 2K rather than 1K.
