Resolution12/2/2023 An HD display has a maximum resolution of 1920 x 1080 pixels, half the resolution of a 4K display (3840 x 2160 pixels). Resolution is often used interchangeably as the “size” of an image, but it also expresses the size of a display, monitor, screen, or TV (display resolution) in relation to its physical ability to focus light. For example, an image with a resolution of 1920 x 1080, has a total of 2,073,600 pixels – which is usually referred to as a “2 megapixel” picture. Image resolution is the total amount of pixels shown by a digital image expressed as width and height proportions. Non-professional printers usually print images between 200 to 300 PPI, while professional instruments usually have higher values, up to 600 PPI. If there are too few pixels in an image, they will look too large and “chunky” if the image is stretched, resulting in pixelated images. The higher the resolution, the crisper is the image and the higher the PPI value since there’s a higher number of pixels in every inch. Note that this is different from display resolution (more on that later), which determines how many pixels are present in a display. The higher the DPI, the sharper the printout will be.įor computer images, the resolution is usually described in pixels per inch (PPI), which is a value that determines how many pixels are displayed per inch in a given picture. This also correlates directly to the recording's quality.įor printers, resolution points to the dots per inch (DPI) of the material the printer produces, which also indicates how small and fine the dots are. This measure also applies to digital images.įor audio, resolution refers to the bit depth of a digital recording, or the number of information bits stored in the sample. Resolution in this case will then refer to how many pixels the display can produce horizontally (width) and vertically (height). In the computer and media industry, resolution refers mostly to display resolution and the number of picture elements (pixels or simply dots) that can be displayed both horizontally and vertically by a screen. Resolution is a broad term and may have different meanings when used in different fields of technology. Resolution is also referred to as screen resolution. It is also used to determine the resolution of a screen, monitor, or TV. The term is popular in the mobile industry for describing a mobile device's display capabilities, and also in the entertainment media to distinguish the visual quality of movies to distinguish between high definition and standard definition movies.
