What is DPI in UI design?
A way to measure the density of a print or video image. The number of differently colored dots that can fit into a one-inch space provides information about the resolution of an image.
What is a high DPI display?
Although all of these resolutions are labeled "high definition (HD)," that doesn't mean that a monitor with one of these resolutions is a high DPI display. High DPI (also known as HiDPI) displays are those that use twice as many physical pixels to represent images than the virtual pixels that make up an image.
Does DPI affect resolution?
The higher the DPI, the sharper the image. A higher resolution image provides the printer and printing device more information. You can get more detail and greater resolution from an image with higher DPI. A lower DPI will produce an image with fewer dots in printing.
