Have you installed the

Set the color depth to 256 colors or higher: use ' C ontrol
Panel' ' D isplay' ' S ettings'
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.
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 IBMMonitor
CD that comes with your monitor.
