Many people don't realize that the physical size of a computer monitor is independent of the amount of space available for the computer desktop—referred to as the monitor resolution. For example, you could run both a 14- and a 21-inch monitor in the 640x480 resolution if you wanted to. Likewise, you could set your 17-inch monitor to run anything from a low 640x480 resolution to a high 1920x1440 resolution. Figures 1-1 and 1-2 at the beginning of the chapter show how changing your monitor's resolution from one resolution to another affects the amount of space on your computer desktop. These figures demonstrate how the monitor's resolution most affects Photoshop—the higher your resolution, the more space you have for all those palettes and windows!
