Power Saving Function; Damper Wires; Plug & Play - IBM P72 Operating Instructions Manual

Technical Features

Power Saving Function

This monitor meets the power-saving guidelines set by
VESA and Energy Star, 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.

Damper Wires

When viewing a white background, very thin horizontal
lines may be visible on the screen as shown below. These
lines are the shadows of the damper wires and are
characteristic of CRTs that use aperture grilles. The wires
are attached to the aperture grille on the inside of the
Trinitron tube and prevent the vibration of the aperture
grille.

Note
If the video signal cable is not connected, the "NO INPUT
SIGNAL" message (page 15) appears. After 30 seconds, the power
saving function automatically puts the monitor into the active-off
mode and the u indicator lights up orange. Once the horizontal
and vertical sync signals are detected, the monitor automatically
resumes its normal operation mode.

Plug & Play
This monitor complies with the DDC 1 and DDC2B
Display Data Channel (DDC) standards of VESA.
When a DDC1 host system is connected, the monitor
synchronizes with the V. CLK in accordance with the VESA
standards and outputs the EDID (Extended Display
Identification Data) to the data line.
When a DDC2B host system is connected, the monitor
automatically switches to the appropriate standard.
DDC is a trademark of the Video Electronics Standard
Association.
