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.
