CONNECTION

—

• 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.)
