Lenovo X131E manual Audio problems, Double-click Sound, video and game controllers

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.

•Problem: A volume or balance slider cannot be moved.

Solution: The slider might be grayed out. This means that its position is fixed by the hardware and cannot be changed.

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

Solution: It is normal for the sliders to change position when certain sound programs are used. The programs 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 program has sliders available to control the sound from within the program.

•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.

•Problem: There is no volume control for MIDI sound in the Volume Mixer window.
