Frequently Asked Questions (FAQ)
✓ The image is blurred:
☞ Read the chapter, "Installation/Adjustment" and 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.
