Frequently Asked Questions (FAQ)

The image is blurred:

Read the chapter, Installation/Adjustment 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?

Read the chapter Installation/Adjustment. Select the native resolution.

Pixel errors can be seen:

One of several pixels are permanently black, one or more pixels are permanently white, one or more pixels are permanently red, green, blue or another colour.

Read the chapter Pixel error rates.

The image has a faulty colour appearance:

It has a yellow, blue or pink appearance.

On the monitor press the "Enter" key and use "<" or ">" key to select "RECALL" item and press "Enter" key. Press "<" or ">" key to select "YES" and press "Enter" to recall fac- tory settings. If the image is still not cor rect 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 chapter, Additional Help, Repairs & 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 "Enter" button on the monitor to access the On Screen Display. If the message "Not supported Mode" appears there, read the chapter Installation/Adjustment.
