C HECK THE MONITOR CABLE CONNECTION —
• Ensure that the monitor cable is connected to the correct graphics card (for dual
graphics card configurations).
• If you are using the optional DVI-to-VGA adapter, ensure that the adapter is
correctly attached to the graphics card and monitor.
• Ensure that the monitor cable is connected as shown on the setup diagram for your
computer.
• Remove any video extension cables and connect the monitor directly to the computer.
• Swap the computer and monitor power cables to determine if the monitor’s power
cable is defective.
• Check the connectors for bent or broken pins (it is normal for monitor cable
connectors to have missing pins).

on.
• If the power light is blinking, press a key on the keyboard or move the mouse to
resume normal operation.
