About 4K

Technically speaking, 4K is the resolution of 4096 x 2160. This is the resolution of all 4K recordings, though many people use 4K to refer to any display resolution that has roughly 4000 horizontal pixels. The Digital Cinema Initiatives consortium established a standard resolution of 4096 × 2160 for 4K film projection. This 4K resolution is native for DCI-compliant 4K digital projectors and monitors; In the 4K high-definition video, pixels are cropped from the top or sides depending on the aspect ratio of the content being projected. The same as you thought, the 4K standard has twice the horizontal and vertical resolution of DCI 2K, with four times as many pixels overall.

Sony, Canon, Nikon, GoPro, DJI and Panasonic have already released 4K cameras for professional usage, 4K digital films may be scanned, produced, or stored in a number of other resolutions depending on what storage aspect ratio is used. 4K is not only used as the abbreviation of 4K resolution but also stands for videos in such premium quality, which is a resolution possessing over 4,000 pixels in the horizontal direction. The resolution is now widely adopted by videos in the film industry. In brief, 4K is 4 times better than 1080p which used to be called the best resolution in digital videos.
