Technical Features

Power saving function

This monitor meets the power-saving guidelines set by VESA, NUTEK, and

NERGY

TAR. If the monitor is connected to a computer

or graphics board that is DPMS (Display Power Management Signaling) compliant, the monitor will automatically enter the power saving
mode.

DPMS defines three power saving states according to the state of
the sync signals supplied from the computer. This monitor’s
power consumption is input at approximately 3 W in all of these
states if the power saving function is set to ON.
When your computer enters in the power saving mode, the input
signal is cut and NO INPUT SIGNAL appears on the screen.
After a few seconds, the monitor enters power saving mode.

* “Sleep” and “deep sleep” are power saving modes defined by the

Environmental Protection Agency.

Note

The power saving function may not work normally if sync signals other
than those listed above are supplied. In such a case, set the power saving
function to OFF.

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 phase, pitch, and picture
position, 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, 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 power switch, and INPUT button will operate.
