Audio Problems - Lenovo ThinkPad S2 3rd Gen User Manual

5. Click Display adapter properties.
6. Click the Monitor tab.
7. Select the correct screen refresh rate.
• Problem: Wrong characters are displayed on the screen.
Solution: Ensure that you follow the correct procedure when installing the operating system and program.
If they are installed and configured correctly, but the problem still persists, have the external monitor
serviced.
• Problem: The Extend desktop function does not work.
Solution: Enable the Extend desktop function. See "Using an external display" on page 35.
• Problem: I am using the Extend desktop function, but I 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. See "Using
an external display" on page 35.
• 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 1600 x 1200 pixels, the image is shifted to
the 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 more information, see the documentation that comes with the monitor.
