Frequently Asked Questions (FAQ)

The image is blurred:

Read the Installation/Application section, and then select the correct resolution, refresh rate and 
make adjustments based on these instructions.

How 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 by 
working through the instructions in the Installation/Adjustment section 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 Installation/Adjustment section. Select the native resolution.
