Points to check with possible solutions
These are dampening wires. Dampening wires are used to support the CRT’s aperture grille, and are visible as thin dark lines across the screen. All EIZO aperture- grille type CRTs include two such
horizontal wires.
The aperture grille itself is a grid of taut metal filaments that spans the entire screen from top to bottom.
The aperture grille may be misaligned. Shock or vibration during transport may, in some cases, cause the aperture grille to fall out of alignment. The problem will appear as one or more faint black lines across the screen.
If this problem occurs, it may be able to solved by:
•degaussing the screen, or
•lightly tapping (do not hit) the side of the monitor.

1)Display a bright white field over the area where the black line(s) appear, with a black field over the unaffected areas. (Do this by opening a
2)Set brightness and contrast to maximum values, and keep the display ON until the problem is corrected. Try tapping the side of the display lightly to help expedite realignment. The white field will heat up the misaligned area of the grille, returning it to proper alignment.
