Technical Features
Preset and user modes
When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in the
monitor’s memory to provide a high quality picture at the center
of the screen. (See page i for a list of the factory preset modes.)
For input signals that do not match one of the factory preset
modes, the digital Multiscan technology of this monitor ensures
that a clear picture appears on the screen for any timing in the
monitor’s frequency range (horizontal: 30 – 107 kHz (GDM-
F400) or 30 – 121 kHz (GDM-F500), vertical: 48 – 160 Hz) . If
the picture is adjusted, the adjustment data is stored as a user
mode and automatically recalled whenever the same input signal
is received.

Troubleshooting

If thin lines appear on your screen
(damper wires)
(damper wires)
The lines you are experiencing on your screen are normal for the
Trinitron monitor and are not a malfunction. These are shadows
from the damper wires used to stabilize the aperture grille and are
most noticeable when the screen’s background is light (usually
white). The aperture grille is the essential element that makes a
Trinitron picture tube unique by allowing more light to reach the
screen, resulting in a brighter, more detailed picture.
