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 – 121 kHz, vertical: 48 – 160 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 video 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 1 (power)
indicator
≤ 145 W
normal green
operation
≤ 100 W
1 standby green and orange
alternate
≤ 15 W
2 suspend green and orange
(sleep)* alternate
3 active off** Approx. 1 W orange
(deep sleep)*
power off 0 W 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 a power saving mode.

Troubleshooting

Before contacting technical support, refer to this section.
If thin lines appear on your screen
(damper wires)
The lines you are experiencing on your screen are normal for the
Trinitron monitor and are not a malfunction. These are shadows
from the damper wires used to stabilize the aperture grille and are
most noticeable when the screen's background is light (usually
white). 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.
Damper wires
On-screen messages
If there is something wrong with the input signal, one of the
following messages appears on the screen.

This message shows the currently selected connector
(HD15 or BNC). 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 so that
the horizontal frequency is between 30 - 121 kHz, and the
vertical frequency is between 48 - 160 Hz.
