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:
