Frequently asked questions (FAQ)
The image is blurred.
Read the instructions in Adjusting the screen resolution on page 24, 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 Adjusting the screen refresh rate on page 25. 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 in Adjusting the screen resolution on page 24. 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.
Go to 
Recall 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 blue?
If the LED is illuminated in blue 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 Preset display modes on page 26.
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.

If your problems remain after checking this manual, please contact your place of purchase or 
e-mail us at: [email protected].
Is the prompt on the display illuminated in blue?
If the LED is illuminated in blue, the power management mode is active. Press any button on 
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.

correct resolution, refresh rate and make adjustments based on these instructions.
You are running the monitor at its native resolution, but the image is still distorted.
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 
Adjusting display mode on page 19
 for details.
The image is displaced in one direction.
Read the instructions in Adjusting the screen resolution on page 24, and then select the 
correct resolution, refresh rate and make adjustments based on these instructions.
 
						

							24  Adjusting the screen resolution  
Adjusting the screen resolution
Due to the nature of liquid crystal display (LCD) technology, the picture resolution is always 
fixed. For the best display performance, please set the display to its maximum resolution that is 
the same with the monitor aspect ratio. This is called “Native Resolution” or maximal resolution 
– that is, the clearest picture. Please refer to the table below for the native resolution of your 
LCD. Lower resolutions are displayed on a full screen through an interpolation circuit. Image 
blurring across pixel boundaries can occur with the interpolated resolution depending upon the 
image type and its initial resolution.
1.  Open 
Display Properties and select the Settings tab. 
Yo u  c a n  o p e n  Display Properties by right-clicking on the Windows desktop and selecting 
Properties from the pop-up menu.
2.  Use the slider in the ‘Screen area’ section to adjust the screen resolution.
Select the recommended resolution (maximum resolution) then click Apply.
3.  Click OK then Ye s. 
4.  Close the 
Display Properties window.
If your input source does not provide an image which is the same with the monitor aspect ratio, 
the displayed image may appear stretched or distorted. To maintain the original aspect ratio, 
image scaling options can be found in the “Display Mode” adjustment. See the user manual for 
more information.

To find out the monitor aspect ratio of the purchased model, please check the Specification document on the 
provided CD.
• To take full advantage of LCD technology you should select the native resolution setting of your PC screen as 
described below. Be aware that not all PC video cards provide this resolution value. If yours doesnt, check 
with the video card manufacturers website for an updated driver for your particular model PC video card 
which supports this resolution. Software video drivers are often updated and available for new hardware video 
resolutions. If necessary, you may need to replace and update the PC video card hardware to be able to 
support the native resolution of the monitor.
• Depending on the operating system on your PC, different procedures should be followed to adjust the screen 
resolution. Refer to the help document of your operating system for details.
If you select some other resolution, be aware that this other resolution is interpolated and may not accurately 
display the screen image as well as it could do at the native resolution setting.

Adjusting the screen refresh rate 
You don’t have to choose the highest possible refresh rate on an LCD display, because it is not 
technically possible for an LCD display to flicker. The best results are obtained by using the 
factory modes already set in your computer. Check next chapter to see the factory modes: 
Preset

Image disruption may occur as a result of signal frequency differences from graphic cards which 
do not correspond with the usual standard. This is not, however, an error. You may improve this 
situation by altering an automatic setting or by manually changing the phase setting and the pixel 
frequency from the “DISPLAY” menu.
