Set the color depth to 256 colors or higher: use ' C ontrol

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.
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.
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 ' M OIRE' icon on
the screen adjustment menu to adjust the screen.
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:
