What is 4K Resolution?
The term "4K" refers to the size (in pixels) of the video image that a camera can record or that a television or monitor screen can display. A "4K" video or image is approximately 4000 pixels wide. This gives a resolution about four times as high as a standard high-definition television. This translates to a far clearer picture with greater resolution, allowing you to capture fine details. 4K is also called UHD (Ultra High Definition).
