No video is
displayed on the
monitor screen. Check the following:
• Is the cable connected to the video connector?
• Does the monitor work when connected to another system?
• If you have another monitor, does it work when connected to the
original system?
• If, after POST and BIOS complete, you no longer see video output
on your monitor and only see a flashing cursor, check the
configuration of the operating system to determine if it is
configured to redirect its output exclusively over the serial line.

device drivers must be installed.
• Ensure that the cables for the external device are firmly connected

the system.
