Frequently asked questions (FAQ)
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 Adjusting 
the Screen Resolution. 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.
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.
•These are pixels that are permanently on or off and is a natural defect that occurs in LCD 
technology.
The image has a faulty coloration:
It has a yellow, blue or pink appearance.
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 
primary colors is missing in the signal input. Now check the signal cable connectors. If any pin is 
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 
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 “Preset display modes” section from the link Adjusting 
the Screen Resolution. 
Faint shadow from the static image displayed is visible on the screen:
•Activate the power management function to let your computer and monitor go into a low 
power sleep mode when not actively in use.
•Use a screensaver to prevent the occurrence of image retention.

Is the prompt on the display illuminated in orange?

the computer keyboard or move the mouse. If that does not help, check the signal cable 
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?
Check the power supply mains socket, the external power supply and the mains switch.

Images from different input sources may appear distorted or stretched on the monitor running at 
its native resolution. To have the optimal display performance of each type of input sources, you 
can use the Display Mode function to set a proper aspect ratio for the input sources. See Display 
Mode on page 27
