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 – 86 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 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 no signal is received by the
monitor from the connected computer, the monitor will
automatically reduce power consumption as shown below.

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 there is something wrong with the input signal, one of the
following messages appears on the screen. To solve the problem,
see "Trouble symptoms and remedies" on page 13.
