Q7 When I used an external display device with the SXGA+ system
and disconnected the device from the system, the original screen
resolution is not restored.
A In general, when using an external display device with low resolution, the LCD
resolution is degraded while using the device and the original resolution is
restored automatically after disconnecting the external display device. If the origi-
nal resolution is not restored when disconnecting the external display device,
complete the following procedures.
Press <Fn>+<F4 / CRT/LCD> keys to change the display device.
Otherwise, click the Ati icon on the taskbar, and change the screen resolution to
the correct setting.
Q8 Pressing a function key in DOS mode does not display the OSD
(status display icon) on the screen.
A The system does not support OSD display when in DOS mode.
Q9 When I am using two display devices such as LCD and CRT, DVD
or MPEG video files are displayed only on the LCD.
A When you are using two display devices, video files are displayed on one device
only as default. To view on both devices, change the setting as follows.
1. Right-click on the desktop, and click Properties.
2. Click Settings tab.
3. Click Advanced, then click Overlay tab. When a message dialog box appears,
click OK.
4. Select ‘Theater Mode’ and click OK.
Q10 When I connected or disconnected AC adapter to/from the
computer, the screen blinks or shows an afterimage.
A This computer uses Powerplay function which extends battery using time. When
you connect or disconnect AC adapter while using Powerplay function, video
chipset’s clock speed changes causing the screen to blink or show an afterimage.
To avoid this problem, disable the Powerplay function.
1. Right-click on the desktop, and click Properties.
2. Click Settings tab.
3. Click Advanced, then click POWERPLAY tab.
4. Clear ‘Enable POWERPLAY’ check box and click OK.
