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 – 70 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 NERGY S 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.
* Figures reflect power consumption when no USB compatible
peripherals are connected to the monitor.
** When your computer enters the “active off” mode, the input signal is
cut and NO INPUT SIGNAL appears on the screen. After 20 seconds,
the monitor enters the power saving mode.
*** If the horizontal or vertical sync signal is received by the monitor, the
power indicator may alternately blink green and orange.
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 14.
The input signal condition
OUT OF SCAN RANGE
indicates that the input signal is not supported by the
monitor’s specifications.
NO INPUT SIGNAL
indicates that no signal is being input to the monitor.
