<hardware> The distance between a dot and the closest dot of the same
colour (red, green or blue) on a color CRT. Dot pitch is typically from 0.28 to
0.51 mm but large presentation monitors may go up to 1.0 mm. The smaller the dot
pitch, the crisper the image, 0.31 or less provides a sharp image, especially
when displaying text.
Dot pitch measurements between conventional tubes and Sony's Trinitron tubes are
roughly, but not exactly comparable. Sony's CRTs use vertical stripes, not dots,
and its measurement is the distance between stripes, not the diagonal distance
["The Computer Glossary", Alan Freedman].
