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.

 

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.

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.

 

If there is something wrong with the input signal, one of the 
following messages appears on the screen.
