Why is there a horizontal line or wire visible across the monitor
screen?
Your 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
■ Adjust the brightness and contrast controls.
■ Use the monitor degauss feature (see your monitor documentation) or turn
off your computer and monitor, leave them off for at least a half hour,
then restart your computer.
■ Change the display settings.
■ Move the monitor away from sources of electrical interference, such as
televisions, unshielded speakers, microwaves, fluorescent lights, and metal
beams or shelves.
For more information about display types, see your monitor and video card
documentation.
