The CONVERGENCE settings allow you to adjust the quality of 
the picture by controlling the convergence. The convergence 
refers to the alignment of the red, green, and blue color signals.
If you see red or blue shadows around letters or lines, adjust the 
convergence.
These settings are stored in memory for all input signals.

The SCREEN settings allow you to degauss (demagnetize) the 
monitor manually and adjust the picture quality by controlling the 
moire and landing. 
• If the color is not uniform or picture is fuzzy, degauss the 

monitor (DEGAUSS).

• If elliptical or wavy patterns appear on the screen, cancel the 

moire (CANCEL MOIRE).

• If the color is irregular at the corners of the screen, adjust the 

landing (LANDING) (CPD-G520 only).

The monitor is automatically demagnetized (degaussed) when the 
power is turned on.
The screen is degaussed for about 2 seconds. If a second degauss 
cycle is needed, allow a minimum interval of 20 minutes for the 
best result.

The CANCEL MOIRE setting is stored in memory for the current 
input signal. All other settings are stored in memory for all input 
signals.

*

Moire is a type of natural interference which produces soft, wavy lines 
on your screen. It may appear due to interference between the pattern 
of the picture on the screen and the phosphor pitch pattern of the 
monitor.

** The LANDING and RESET functions are for CPD-G520 only.

 

The picture may become fuzzy when the CANCEL MOIRE function is 
activated.

 

The COLOR settings allow you to adjust the picture’s color 
temperature by changing the color level of the white color field. 
Colors appear reddish if the temperature is low, and bluish if the 
temperature is high. This adjustment is useful for matching the 
monitor’s color to a printed picture’s colors.
You can set the color temperature for each of the video input 
connectors.
