Troubleshooting

❐

Do you see basic
discoloration (16 colors)?

❐

Is the screen color
unstable or monochrome?

❐

Do you see black dots on
the screen?

❐

Do you see a partial
blurring on the screen?

•    

Set the color depth to 256 colors or higher: use 'Control
Panel' -> 'Display' -> 'Settings' -> 'Color Palette'

•    

Check the connection of the signal cable. Or pull out the
video card of the PC and insert it again.

•    

This is due to a small amount of foreign or abnormally
florescent material that became fastened on the mask
during manufacturing. It will not affect product
performance.

•    

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?

•    

A premature aging of the monitor pixels may cause the
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.

I see waves on the screen.

❐

Have you installed the
monitor driver?

•    

Be sure to install the monitor driver from the monitor driver
CD (or diskette) that comes with your monitor. Or, you
can also download the driver from our web site:
