NOTE:

See the monitor documentation for troubleshooting procedures.

Check the monitor cable connection —

If you purchased a graphics card, ensure that the monitor is connected to the card.

Ensure that your monitor is properly connected (see the Setup and Quick Reference Guide that came

with your computer).

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 if the power cable is defective.

Check the connector for bent or broken pins. (It is normal for monitor cable connectors to have missing

pins.)

Check the monitor power light —

If the power light is off, firmly press the button to ensure that the

monitor is turned on. If the power light is lit or blinking, the monitor has power. If the power light is blinking,

press a key on the keyboard or move the mouse.

Test the electrical outlet —

Ensure that the electrical outlet is working by testing it with another device,

such as a lamp.

Test the monitor —

Connect a properly working monitor to the computer, and try using the monitor. If the

new monitor works, the original monitor is faulty.

Check the

Diagnostic Lights

Check the card setting —

Enter system setup

and ensure that Primary Video Controller under the

Integrated Devices option is set correctly. For a PCI card, set Primary Video Controller to Auto. Exit

system setup and restart your computer.
