■ You demagnetize the screen using the monitor’s degauss feature. For more
information on degauss, see the monitor’s documentation.
A horizontal line or wire is visible across the monitor screen
The monitor may use a thin damper wire, located approximately 1/3 of the way
down from the upper screen edge and 1/3 of the way up from the lower screen
edge, to stabilize the internal aperture grille. These wires are most obvious when
the monitor displays a white background. The aperture grille allows more light
to pass through the screen for brighter colors and greater luminescence. The
damper wire is a critical part of the overall monitor design and does not
negatively affect the monitor's function.
The text on the display is dim or difficult to read
