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 – 107 kHz, vertical: 48 – 120 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 graphic board manual or the
utility program which comes with your graphic 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,
E S
NERGY TAR, and NUTEK. If the monitor is connected to a
computer or video graphics board that is DPMS (Display Power
Management Signaling) compliant, the monitor will automatically
reduce power consumption in three stages as shown below.
Power mode Power consumption

* "Sleep" and "deep sleep" are power saving modes defined by the
Environmental Protection Agency.
** When your computer is in a power saving mode, MONITOR IS IN
POWER SAVE MODE appears on the screen if you press any button
on the monitor. After a few seconds, the monitor enters the power
saving mode again.

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.

On-screen messages

If no picture appears on the screen, one of the following messages
appears on the screen. To solve the problem, see "Trouble
