Troubleshooting
Do you see basic
discoloration (16 colors)?
Is the screen color unstable

Do you see a partial
blurring on the screen?

Panel' 'Display' 'Settings' 'Color Palette'
Check the connection of the signal cable.
This happens due to interference from surrounding
magnetic fields, as created when speakers, steel
structures, or high-voltage lines are placed near the
monitor. Remove any such materials from the
immediate vicinity and use the DEGAUSS icon on the
screen adjustment menu to fix the screen.
Do you see the after-image
even when you turn off
the monitor?

prolonged display of a single image on the screen. Be
sure to use a screen saver to maximize the service life of
the monitor.
The screen color is not normal.
I see an after-image on the screen.
Do you see the wave
directly on the screen?
This occurs in inverse proportion to the screen focus,
which can be caused by a particular frequency or video
card. Brighten the screen and use the 'MOIRE' icon on
the screen adjustment menu to adjust the screen.
