NOTE Arrangement and number of connectors may vary by model.

The monitor connector on the system board is inactive when a PCI Express graphics card is installed in the computer. The integrated graphics can be enabled if a graphics card based on an ATI graphics controller is plugged into the PCIe x16 slot.

If a PCI graphics card is installed, the connectors on the card and the system board may be used at the same time. Some settings may need to be changed in Computer Setup to use both connectors. For information about Boot Order, refer to the Computer Setup (F10) Utility Guide on the Documentation and Diagnostics CD.

The DVI-D connector will only work with display devices that have DVI input.

The Line-In and Line-Out audio connectors can be “retasked” to work as either Line-In, Line-Out, or Microphone connectors by clicking the Realtek HD Audio Manager icon (a red speaker) in the task tray or the Realtek entry in the operating system's Control Panel and selecting the Retasking Enable button.

1An optional second serial port that installs into an expansion slot on the back of the computer is available from HP.
