This article will explain in detail what the resolution 2k refers to. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Resolution 2k means that the horizontal resolution of the screen or content is about 2000 pixels. Because the 16:9 ratio is the international standard for high-definition video specifications, the common formats of 2k resolution in video production, display screens and other fields are 1440p and 1080p.

2K resolution (English name 2K resolution) is a general term, which means that the horizontal resolution of the screen or content is about 2000 pixels, while the 2K resolution of traditional movies is 2048 × 1080.

Because the 16:9 ratio is the international standard for high-definition video specifications, the common formats for 2K resolution in video production, display screens and other fields are 1440p (Quad HD) and 1080p (FullHD).

In 2005, the Digital Film Alliance (Digital Cinema Initiatives,DCI) defined the standard of DCI 2K resolution as 2048 × 1080. [2] but the general term 2K was not coined by DCI. 2K was used in the film industry earlier than the release of the DCI standard.

Classified from the general definition of 2K resolution, all content with a horizontal resolution of about 2000 pixels belongs to the category of 2K. In the film industry, films with a horizontal resolution of 1804 pixels are still discussed as 2K resolutions. The horizontal resolution of 1080p is 1920 pixels, which meets the requirement of "horizontal resolution of about 2000 pixels" with 2K resolution. Although 1080p and 2K are usually treated differently in the fields of photography and film and television production, it does not conflict with the category of 1080p with 2K resolution.
