Automatic brightness adjustment function (light sensor)
This monitor is provided with a feature to automatically adjust the screen brightness according to the brightness of the surroundings. The
brightness of the backlight is set to the most appropriate level by setting the light sensor to ON. The default setting of the brightness of the
backlight is set to its maximum. When the light sensor setting is set to ON, the monitor adjusts the brightness of the backlight linearly from
its lower- to upper-limit values. When the user adjusts the backlight, the backlight brightness is automatically adjusted between the user
adjustment value and the upper- and lower-limit values.
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: 30 –
61 kHz, vertical: 48 – 85 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 on the adjusting the phase
If the automatic picture quality adjustment function is activated, the
picture moves slightly whenever the monitor receives the input signal,
regardless of the stored adjustment.
Note
While the automatic picture quality adjustment function is activated, only
the
1
(power) switch, and INPUT button will operate.
