• Ensure that the graphics cable is connected as shown on the setup diagram for
your computer.
If an optional video card is installed, check that the monitor cable is connected to
the card, rather than the video connector on the system board.
• If you are using a graphics extension cable and removing the cable solves the
problem, the cable is defective.
• Swap the computer and monitor power cables to determine whether the power
cable is defective.
• Check the connector for bent or broken pins. (It is normal for monitor cable
connectors to have missing pins.)
