The image is blurred:

Read the instructions on the link "

Adjusting the Screen Resolution

" on the CD, 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 "

Adjusting the refresh rate

" section 

on the link

. 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 instructions on the link "

Adjusting the Screen Resolution

" on the CD.

 

Select the 

native resolution.

bent or broken off, please contact your dealer to get necessary support.

No image can be seen:

If the LED is illuminated in green and there is a message “Out of Range” on the screen, this means 
you are using a display mode that this monitor does not support, please change the setting to one 
of the supported mode. Please read the “
