Q7 When I pressed <Fn>+< > keys to change display devices, the
screen resolution is changed.
A Change the resolution again on [Graphics Controller Properties] dialog.
((P. 6-8) Refer to ‘Using External Display Devices’.)
Q8 <Fn>+< > keys do not operate.
A When you are playing a video file such as a video CD, an MPEG file, or a DVD,
when no external display is connected, or when you are using the extended
desktop mode or full screen DOS mode, you cannot change display devices.
Q9 Desktop is displayed abnormally or some icons disappear while
the system is operating.
A This problem may occur when you entered hibernate mode while using the
Extended Desktop mode, removed the monitor and then pushed power button to
exit hibernate mode.
When the desktop is displayed abnormally, press right touchpad button on the
desktop and click Refresh. When the icons disappear, press <Fn>+<
> or
<Ctrl>+<Alt>+<F3> to change the display setting.
Q10 When I played DVD or Video CD in Dual Display Clone mode or
Extended Desktop mode, actions such as changing display
setting or volume operates slowly.
A Playing DVD or Video CD requires separate data handling. When you are using
Dual Display Clone mode or Extended Desktop mode, problem may occur
because the data exceeds the capacity of the video chip. Change the display
device to display only on LCD or only on CRT.
