Many things can cause the monitor to flicker; they are all simple to fix and do not
require hardware replacement.
First, turn the monitor off and then back on. You may also press the degauss button if
your monitor has one (refer to the documentation that came with your monitor) to get
rid of any magnetic field that may have developed during normal monitor operation.
Next, try moving the monitor to the other end of the desk to get rid of the flicker. Also
try separating the monitor from sources of electrical interference (such as speakers,
power cables, fluorescent lights, or something in the wall or on the other side of the
wall).
Finally, increase the refresh frequency if both the monitor and video controller support
a higher rate at the chosen resolution. For instructions, refer to “Changing the Refresh
Rate in Windows 98” or “Changing the Refresh Frequency in Windows NT” in
Chapter 4.
