AUTOMATIC PICTURE QUALITY ADJUSTMENT FUNCTION
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 automatic picture quality adjustment function of this
monitor automatically adjusts the picture position, phase, and
pitch, and ensures that a clear picture appears on the screen for
any timing within the monitor , s frequency range (horizontal: 28 -
60 kHz , vertical: 48 - 75 Hz ).
Consequently, the first 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 whenever
the same input signal is received.
Note
While the automatic picture quality adjustment function is activated, only
the (power) switch will operate.
