What is 4K/UHD 4K/UHD displays have approximately 4,000 pixels of horizontal resolution, hence the term “4K”. The corresponding number of vertical lines of resolution, determined by the aspect ratio, is nearly 2,000. The number of pixels on the screen is the product of the horizontal and vertical resolutions. At just over eight megapixels, 4K/UHD is four times the resolution of a High Definition display, and 24 times that of a DVD movie. This provides a significantly higher level of detail and sharpness because the image is comprised of more pixels. 4K/UHD Aspect Ratio Two different aspect ratios are used for 4K displays, 16:9 UHD and 17:9 DCI 4K. NDS 4K displays utilize the 16:9 UHD format, which directly corresponds to the output of today’s 4K endoscopic cameras. Displaying a 16:9 image on a 17:9 monitor necessitates down-scaling to fit the screen. As a consequence of the mismatched aspect ratios, letterboxing and a physically smaller image size results.
