Power Saving Function
This monitor has three modes of reduced power
consumption. By sensing the absence of video signal
coming from the computer, it reduces power consumption
as follows.
Power Power Recovery u indicator
consumption consumption time

Note
If the video signal cable is not connected properly, the "NO INPUT
SIGNAL" message (page 18) 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.
Getting Started Technical Features

Damper Wires

When viewing a white background, very thin horizontal
lines are visible on the screen as shown below. These lines
are damper wires.
The Trinitron tube has a vertically striped aperture grille
inside. The aperture grille allows more light to pass through
to the screen giving the Trinitron CRT more color and
brightness.
These damper wires are attached to the aperture grille to
prevent vibration of the aperture grille and keep the screen
image constantly stable.
