Note: If your computer cannot detect the external monitor, click the Detect button.

4.Click the icon for the desired monitor (the Monitor-2icon is for the external monitor).

5.Click Advanced Settings.

6.Click the Monitor tab.

7.Select the correct screen refresh rate.

•Problem: Wrong characters are displayed on the screen.

Solution: Did you follow the correct procedure when installing the operating system or program? If you did, have the external monitor serviced.

•Problem: The Extend desktop function does not work.

Solution: Enable the Extend desktop function. See “Using the Extend desktop function” on page 41.

•Problem: If you use the Extend desktop function, you cannot set a higher resolution or higher refresh rate on the secondary display.

Solution: Change the resolution and the color depth to lower settings for the primary display.

•Problem: Display switching does not work.

Solution: If you use the Extend desktop function, disable it, and change the display output location. If a DVD movie or a video clip is playing, stop the playback, close the program, and then change the display output location.

•Problem: The screen position on the external monitor is incorrect when that monitor is set for a high resolution.

Solution: Sometimes, when you use a high resolution such as 1600x1200, the image is shifted to left or right on the screen. To correct this, first make sure that your external monitor supports the display mode (the resolution and the refresh rate) that you have set. If it does not, set a display mode that the monitor supports. If it does support the display mode you have set, go to the setup menu for the monitor itself and adjust the settings there. Usually the external monitor has buttons for access to the setup menu. For details, see the documentation that comes with the monitor.

1.Open Control Panel and click Hardware and Sound.

2.Click the Realtek HD Audio Manager icon.

3.Make sure that you are in MULTI-STREAM mode in the Device advanced settings window.
