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.
