Frequently asked questions (FAQ)
The image is blurred:
Read the How to adjust the screen resolution on page 21 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 on page 22 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 How to adjust the screen resolution on page 21 section. Select the native resolution.
Pixel errors can be seen:
One of several pixels is permanently black, one or more pixels are permanently white, one or more 
pixels are permanently red, green, blue or another color.
•  Clean the LCD screen.
•  Cycle power on-off.

Select MENU > PICTURE > Color > Reset Color, and then choose “Yes” in the “Caution” message 
box to reset the color settings to the factory defaults. 
If the image is still not correct and the OSD also has faulty coloration, this means one of the three

bent or broken off, please contact your dealer to get necessary support.
No image can be seen:
Is the prompt on the display illuminated in green?
If the LED is illuminated in green and there is a message “Out of Range” on the screen, this means

Is the prompt on the display illuminated in orange?

connectors. If any pin is bent or broken off, please contact your dealer to get necessary support.
Is the prompt on the display not illuminated at all?
