Resolution is the term used to describe the number of dots, or pixels, used to display an image.

Higher resolutions mean that more pixels are used to create the image, resulting in a crisper, cleaner image.

The display, or resolution on a monitor, is composed of thousands of pixels or dots. This display is indicated by a number combination, such as 800 x 600. This indicates that there are 800 dots horizontally across the monitor, by 600 lines of dots vertically, equaling 480,000 dots that make up the image you see on the screen.


The resolution setting on the computer monitor was set for 800 pixels wide by 600 pixels deep.
