A.2 Troubleshooting
The image is displayed incorrectly/the full screen image does not appear
 Ensure that the screen resolution on the motherboard is correct.
The screen image is not centered

Adjust the horizontal and vertical position of the OSD or select the “Auto” option
for automatic adjustment.
Out of range
 If an “Out of Range” message appears onscreen, this indicates that the display
output signal is not compatible with the LCD display (for example, the output
resolution exceeds the LCD display resolution).
 Adjust the BIOS settings to match the correct resolution.
No signal
 The display is powered on but is not receiving or displaying output signals from
the computer. Check all power switches, power cables, and VGA signal cables
and ensure that both ends of all cables are properly connected.
Going to sleep
 If the system goes to sleep, either the display has been set to power-saving
mode or is experiencing a sudden signal disconnection problem. Check the
BIOS system settings and/or Windows configuration. Then check both ends of
the power cable connected to the computer.
