•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 ensure 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.

•Problem: The volume sliders do not stay in place when some audio applications are used.

Solution: It is normal for the sliders to change position when certain sound applications are used. The applications are aware of the settings in the Volume Mixer window and are allowed to change the settings themselves. An example is the Windows Media Player. Usually the application has sliders available

to control the sound from within the application.

•Problem: The balance slider cannot completely mute one channel.

Solution: The control is designed to compensate for minor differences in balance and does not completely mute either channel.
