Power Saving Function

This monitor meets the power-saving guidelines set by
VESA and E NERGY S TAR, as well as the more stringent
NUTEK .
If the monitor is connected to a computer or video graphics
board that is VESA DPMS (Display Power Management
Signaling) compliant, the monitor will automatically reduce
power consumption in three stages as shown below.
Power consumption Screen Horizontal
mode sync signal
1 Normal operation active present
2 Standby (1st mode) blank absent
Suspend (2nd mode) blank present
3
(sleep)*
4 Active-off** (3rd mode) blank absent
(deep sleep)*
5 Power-off — —
* "Sleep" and "deep sleep" are power saving modes defined by the Environmental Protection Agency.
** When your computer enters a 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.

Notes
• The power management feature is invoked when the computer
recognizes that you have not used your mouse or keyboard for a
user-definable period of time.
• IBM recommends that you switch off your monitor at the end of
each working day, or whenever you expect to leave it unused for
long periods during the day.

You can display the model name, serial number and year of
manufacture using the monitor's INFORMATION OSD.
Press and hold the button for 5 seconds.
The INFORMATION OSD appears.
Example:
I NFORMA T I ON
MODE L : I BM P 2 6 0
SER NO : 1 2 - 3 4 5 6 7
MANUF ACTURED : 1 9 9 9 - 5 2
The INFORMATION OSD includes the model name, serial
number, and manufactured year.
The OSD automatically disappears after about 30 seconds.

1 The selected connector
This message shows the currently selected connector
(INPUT 1 or INPUT 2).
2 The input signal condition
NO INPUT SINGAL
This indicates that no signal is input, or that no signal is
input from the selected connector.
3 The remedies
One or more of the following messages may appear on
the screen.
• If ACTIVATE USING PC appears on the screen, try
pressing any key on the computer, and confirm that
your computer's graphic board is completely seated
in the correct bus slot.

1 The selected connector and the
frequencies of the current input signal
This message shows the currently selected connector
(INPUT 1 or INPUT 2). If the monitor recognizes the
frequencies of the current input signal, the horizontal
and vertical frequencies are also displayed.
2 The input signal condition
OUT OF SCAN RANGE
This indicates that the input signal is not supported by
the monitor's specifications.
3 The remedies
CHANGE SIGNAL TIMING appears on the screen. If
you are replacing an old monitor with this monitor,
reconnect the old monitor. Then adjust the computer's
graphic board to that the horizontal frequency is
between 30 - 121 kHz, and the vertical frequency is
between 48 - 160 Hz.
