Troubleshooting
The image is blurred
• Refer to the Installation/Adjustment chapter and then select the
correct resolution, refresh rate and make adjustments based on
these instructions.
• Do you use a VGA extension cable?
Remove the extension cable for the test. Is the image now in
focus? If not, optimize the image working on the description in
the chapter, Installation/Adjustment. It is normal for blurring to
occur due to conduction losses in extension cables. You can
minimize these losses by using an extension cable with better
conduction quality or with a built-in booster.
• Does the blurring only occur at resolutions lower than the native
(maximum) resolution?
Refer to the Installation/Adjustment chapter. Select the native
resolution.
The image has a faulty colour appearance
• It has a yellow, blue or pink appearance.
On the monitor press the "Enter" button and using the Fly-wheel
move to the "colour settings" menu. Select the "Recall" item
and press "Enter". If the image is still not correct and the OSD
also has a fault colour appearance, then one of the three primary
colours is missing in the signal input. Now check the VGA cable
contacts. If any pins are bent or broken off, then contact your
dealer or read the chapters for additional help and service.
No image can be seen
• Is the prompt on the display illuminated in green?
If the LED is illuminated in green, then press the "Exit" button
on the monitor to access the On Screen Display. If the message
"NON PRESET MODE" appears there, read the chapter Instal-
lation/Adjustment.
