connected. (Refer to 3.2, Connecting the Display)
Make sure that none of the connectors are crooked, broken or loose.
Make sure that the OSD power on the LED is turned on.
Make sure that the brightness is not in the minumum.
Make sure that the screen resolution is set to the correct setting for the type of
LCD, and that the setting does not exceed the resolution specified for the partic-
ular model of LCD.
The image is incorrectly displayed, or the full screen image does not appear
Please make sure the screen resolution on the motherboard is correct.
The position of screen is not in the center
Adjust the H-position and V-position or perform "Auto-Tune".
Out of range
When the message "Out of Range" appears onscreen, it indicates that the sig-
nal of the computer is not compatible with the LCD display; i.e. the resolution
exceeds the specified resolution for the LCD.
Adjust the BIOS setting to match the correct resolution.
No signal
The display is powered on, but can neither receive or display any signal from
the computer. Check all power switches, power cables and VGA signal cables
to ensure that all are connected correctly on both sides.
Going to sleep
If the system goes to sleep, then the display has either been set to power-sav-
ing mode, or the display is experiencing a sudden signal disconnection problem.
Check the BIOS system settings, and/or Windows configuration. Then check
the connection of the power cable to computer on both sides.
