One of them is the one adopted by Digital Cinema Initiatives, with a 4096 x 2160 ratio.Īnother variation found is the Ultra Wide HDTV, 5120 x 2160 pixels. It is generally used for 19:10 aspect ratio screens.Īlthough the 3840 x 2160 ratio is the main aspect of this model, the 4K resolution has some variations. The 2K resolution, with proportions 2048 x 1080 pixels, is an intermediate version between Full HD and Ultra HD and ends up not being found in the market.ĢK is mainly adopted by the DCI (Digital Cinema Initiatives) film industry.
They are also suitable for 16: 9 format screens. They have a better image quality than HD, with a 1920 x 1080 aspect ratio, which is equivalent to more than 2 million pixels. They are mainly used on widescreen (16: 9) screens. The screens of HD resolution, or High Definition, are those of 1280 x 720 pixels, that is, almost 1 million pixels. So, saying that a screen has a resolution of 1280 x 720 means that it displays 1280 pixels per line and 720 per column. In this way, the resolution will define how many pixels there are in each row (width) and each column (height). The pixels are the points that make up the image, and are organized in rows and columns. The resolution shows us how many pixels fit on the screen. As the screens are usually rectangular, the measurement is made considering the size of the diagonal. That is, a smartphone with a 5-inch screen is 12.7 centimeters (5 x 2.54). The screen size is measured by inches, each one being 2.54 centimeters. While size refers to the physical dimensions of the screen, resolution is the amount of information displayed within these size limits.
When we talk about screens, we need to take into account two measures: size and resolution. The more pixels, the better the display quality. They differ by the number of pixels that are displayed on the screen, that is, how many points will form the image. HD, Full HD, 2K, 4K, 8K and 10K are different screen resolutions, whether for TVs, monitors, among others.
