monitor to the computer. If the flickering disappears, it is a fair indication
that the monitor is defective, otherwise go to the next step.
3. Set up the computer and the monitor on a
different place in your house. If the flickering disappears now, it is most
likely an interference caused by something in the original location. Check for
devices which can cause interference.
4. If the flickering persists, check the setup
of your system. If available in the setup, make sure that the option Monitor
Type is configured as Colour Non-Interlaced.
