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 Appendix 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 – 70 kHz, vertical:
48 – 120 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.

The lines you are experiencing on your screen are normal for the

from the damper wires used to stabilize the aperture grille and are
most noticeable when the screen’s background is light (usually

Trinitron picture tube unique by allowing more light to reach the
screen, resulting in a brighter, more detailed picture.
