Frequently Asked Questions (FAQ)

The image is blurred:

Read the 

How to adjust the screen resolution

 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 

How to adjust the screen refresh rate

 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
