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 – 96 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.
