When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in
themonitor’s memory to provide a high quality picture at the
centerof the screen.
For input signals that do not match one of the factory
presetmodes, the automatic picture quality adjustment function
of thismonitor automatically adjusts the picture position, phase,
andpitch, and ensures that a clear picture appears on the screen
forany timing within the monitor’s frequency range (horizontal:
28 -61 kHz, vertical: 48 - 75 Hz ).

Consequently, the firdt time the monitor receives input signals
that do not match one of the factory preset modes, the monitor
may take a longer time than normal for displaying the picture on
the screen. This adjustment data is automatically stored in
memory so that next time, the monitor will function in the same
way as when the monitor receives the signals that match one of
the factory preset modes.
In all modes as above, if the picture is adjusted, the adjustment
data is stored as a user mode and automatically recalled when-
ever the same input signal is received.

Note
While the automatic picture quality adjustment function is acti-
vated, only the  (power) switch will operate.
