Technical Features

Preset and user modes

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 digital Multiscan technology of this monitor
ensures that a clear picture appears on the screen for any timing in
the monitor's frequency range (horizontal: 30 – 130 kHz, vertical:
48 – 170 Hz). 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 for Windows users
For Windows users, check your graphics board manual or the
utility program which comes with your graphics board and select
the highest available refresh rate to maximize monitor
performance.

Power saving function

This monitor meets the power-saving guidelines set by VESA and
E S
NERGY TAR. If no signal is input to the monitor from your
computer, the monitor will automatically reduce power
consumption as shown below.
Power mode Power consumption
≤ 135 W
normal
operation
≤ 3 W
active off*
(deep sleep)**

* When your computer enters power saving mode, the input signal is
cut and NO SIGNAL appears on the screen before the monitor enters
active off mode. After a few seconds, the monitor enters power saving
mode.
** "Deep sleep" is power saving mode defined by the Environmental
Protection Agency.

Troubleshooting

Before contacting technical support, refer to this section.
If thin lines appear on your screen
(damper wires)
The visible lines on your screen especially when the background
screen color is light (usually white), are normal for the Trinitron
monitor. This is not a malfunction. These are shadows from the
damper wires used to stabilize the aperture grille. The aperture
grille is the essential element that makes a Trinitron picture tube
unique by allowing more light to reach the screen, resulting in a
brighter, more detailed picture.

following messages appears on the screen.
