• 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 depth to lower settings for the primary display. Refer to the "Solution" for
"The Extend desktop function does not work" above.
• 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, that is, 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 reference manual for the monitor.
