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 color appearance:

It has a yellow, blue or pink appearance.

On the monitor press the “Enter” button and using the Fly-wheel move to the

“color settings” menu. Select the “Recall” item and press “Enter”. If the image is still not correct and the OSD also has a fault color appearance, then one of the three primary colors 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 Installation/Adjustment.

Is the prompt on the display illuminated in orange?

If the LED is illuminated in orange, then the power management mode is active. Press a button on the computer keyboard or move the mouse. If that does not help, then 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.

Is the prompt on the display not illuminated at all?

Check the power supply mains socket, the external power supply and the main switch.

The image is or distorted, flashes or flickers

Refer to the Installation/Adjustment chapter and select the correct resolution, refresh rate and make adjustments based on these instructions.
