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.
