wires used to mask the phosphor tend to vibrate, especially in larger monitors, thin wires
are placed horizontally across them to hold them in place and dampen the vibrations.
This results in very faint lines across the screen where the horizontal wires run.
Dot Pitch and Stripe Pitch
The distance between two phosphor dots of the same color is a monitor’s dot pitch. The
dot pitch (see Figure 16-9) is a measurement in millimeters of how far apart pixels are
placed on the screen. A monitor with a lower dot pitch will produce better images than
one with a higher dot pitch. Although there isn’t a great deal of difference among all of
the monitors on the market, even the smallest difference will show u pon the screen,
especially on a larger monitor. On current monitors, dot pitch distances are in the range
of .24 millimeters (mm) to .31 mm, with .28 mm probably the most common.Figure 16-7. The shadow mask prevents the electron beam from straying off target
