Sony GDM-F400 - Manual (Page 15)

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 page i 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 (GDM-
F400) or 30 - 121 kHz (GDM-F500), 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 mattimize monitor performance.
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
Power saving function
This monitor meets the power-saving guidelines set by VESA,
ENERGY STAR, 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.

* 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 the time set
in “Changing the power saving delay time.” (page 14) has elapsed, the
monitor enters the power saving mode.

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 16.
O INFORMATION
