z Check that the external display settings are correct.
z When an external display not compatible with the power-saving mode is
used with the computer, the display may not function correctly when the
computer enters the power-saving mode. In this case, turn on the external
display again.
However, in the case of some external displays, the screen display may be
distorted or the mouse cursor may not be properly displayed depending on

olution), and refresh rate to smaller values.

play.

for Mobile] - [Devices].
B Click the display destination, and click [OK].

z When [Command Prompt] is set to "Full Screen" by pressing the Alt +
Enter key, the screen is displayed on one of the displays only. Press the
Alt + Enter key to return to the window display.
z Simultaneous display cannot be used until Windows startup is complete
(during Setup Utility, etc.).
‹ Problems with Operation during Use
Some applications may not work
properly z When switching to a different user with the Fast User Switching function,
the following problems may occur:

puter.
z Some software applications installed after the time of purchase are not
compatible with Windows XP Service Pack 2. Refer to software maker’s

puter, turn on again.
