DPI and pixels are similar but different. DPI refers to the resolution of
an image in dots-per-inch. Pixels refer to the number of picture elements a
medium; like a monitor, a flat-panel display, or even a print on paper;
can present. Most monitors display between 70 and 90 pixels per inch.
Therefore, a resolution greater than, say 90 DPI, yields no improvement in
picture definition on the monitor; but if a printer can support a greater
DPI, improvement may result.
