Problems Points to check with possible solutions
10. The Auto sizing function does not
work properly.
The Auto sizing function is intended for use on
the Macintosh and on AT-compatible PC
running Windows. It may not work properly in
either of the following cases. You are running
an AT-compatible PC on MS-DOS (Not
windows). The background color for the "wall
paper" or "desktop" pattern is set to black.
Some signals from graphics card may not
function properly.
11. Two horizontal hairlines are visible
on the screen.
These are damper wires.
Damper 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.
12. Faint black vertical lines are visible
on the screen.
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 solved by:
1. Degaussing the screen.
2. 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.)
(Refer to left figure)
2. Set brightness and contrast to maximum
values, and keep the display ON until the
problem is corrected.
3. 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.
