Considerations for attaching a DVI monitor

Connect the DVI monitor to the expansion unit, and turn it on before you turn on the computer. Otherwise the system cannot recognize the DVI monitor. If the option for enabling the DVI monitor in the Display Properties window is not displayed, try closing the window and opening it again. If the option still is not displayed, make sure that the connector of the monitor is attached firmly, and repeat the procedure for attaching the monitor.
