7 TROUBLESHOOTING

• 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.

If neither of these methods works, try executing the

following procedure.

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

bright-white window on top of a black desktop

or wallpaper background. Position the window

so that it just covers the area of misalignment.)

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.

6) Two horizontal hairlines are

visible on the screen.

7) Faint black vertical lines are

visible on the screen.

Changing the resolution

If you are using a Macintosh, you can change the resolution from the APPLE menu by

selecting “Option” from “Monitor” or “Sound & Display.” If you are using a PC other

than a Macintosh, refer to the manual for your PC or graphics board for information.

Please refer to both the graphics board and monitor manuals for the scanning frequency

compatibility.
