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 (CPD-
G520), 30 – 110 kHz (CPD-G420), 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,
E
NERGY
S
TAR, and NUTEK. If no signal is input to the
monitor from your 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 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.
On-screen messages
If there is something wrong with the input signal, one of the
following messages appears on the screen.
If NO SIGNAL appears on section
1
This indicates that no signal is input from the selected connector.
If OUT OF SCAN RANGE appears on line
1
This indicates that the input signal is not supported by the
monitor’s specifications.
For more information, see “Trouble symptoms and remedies” on
page 20.

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 graphics board so
that the horizontal frequency is between 30 – 130 kHz
(CPD-G520), 30 – 110 kHz (CPD-G420), and the vertical
frequency is between 48 – 170 Hz.
