The color is not uniform
■ Make sure that the monitor warms up for
at least 30 minutes before making a final
judgment about color uniformity.
■ Make sure that:
■ Non-shielded speakers are not
placed too close to the monitor.
■ The monitor is not positioned too
close to another monitor, electric
fan, fluorescent light, metal shelf, or
laser printer.
■ You demagnetize the screen using
the monitor’s degauss feature. For
more information on degauss, see
your monitor’s documentation.
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.
