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" button and using the Fly-wheel move to the "colour set-
tings" 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 chapter, Additional Help, Repairs &
Service.
No image can be seen:
Is the prompt on the display illuminated in green?
