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.
 
						

							46 Troubleshooting  
Is the prompt on the display illuminated in orange?
If the LED is illuminated in orange, 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.
The image is distorted, flashes or flickers:
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.
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 Display 
Mode on page 35
 for details.
The image is displaced in one direction:
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.
The OSD controls are inaccessible:
•To unlock the OSD controls when the OSD is preset to be locked, press and hold the “MENU” 
key for 15 seconds to enter the “OSD Lock” option and make changes. 
•Alternatively, you may use the   or   keys to select “NO” in the “OSD Lock” submenu 
from the “OSD Settings” menu (under SYSTEM), and all OSD controls will be accessible.
No sound can be heard from the built-in speakers:
•Check whether Line In is properly connected.
•Increase the volume (volume may be muted or too low).
•Remove your headphone and/or external speakers. (If they are connected to the monitor, the 
built-in speakers are automatically muted.)
No sound can be heard from the connected external speakers:
•Remove your headphone (if the headphone is connected to the monitor).
•Check whether the headphone jack is properly connected.
•If the external speakers are USB-powered, check whether the USB connection is OK.
•Increase the volume (volume may be muted or too low) on the external speakers.
The light sensor of the monitor does not work well.
The light sensor is located at the front bottom of the monitor. Please check:
•If the Eye Protect function is set to ON. Check Ergonomics > Eye Protect.
•If there are any obstacles in front of the sensor that keep the sensor from detecting the light 
properly.
 
						

							  47   Troubleshooting
•If there are any objects or clothing in bright colors in front of the sensor. Bright colors 
(especially white and fluorescent colors) reflect light and the sensor cannot detect the main 
light sources.
The ECO sensor of the monitor does not work well.
•The ECO sensor is located at the front bottom of the monitor. 
Check if there are any obstacles in front of the sensor that keep the 
sensor from detecting your presence properly.
•The colors and the materials of your clothes may affect the 
detection. Adjust the sensor range if needed. See Sensor Range on 
page 44 for more information.
•Adjust the distance between you and the monitor.
If none of the proceeding actions works, it is probably because the 
materials of your clothes are unique and cannot be detected by the ECO sensor. Please be noted 
that this is neither a manufacturing defect nor is the sensor damaged. You should turn off the ECO 
sensor for now in 
Eco> ECO Sensor.
(For BL2201PU/BL2400PU) USB devices are not working:
•Check whether upstream and downstream USB are properly connected.
•Install a corresponding USB device driver if available.
•The maximum power provided for each USB port on your monitor is 100 mA. Check if a 
message showing 
USB Hub Power Exceeded pops up in the notification area located in the 
lower right corner of the desktop of your computer when your USB device is connected. If so, 
your USB device needs more power than the USB hub can provide and thus is not workable. 
To find the power information of the connected USB device(s), right-click 
My Computer and 
go to 
Properties, Hardware, and Device Manager. Under Universal Serial Bus 
controllers
, double-click Generic USB Hub (4 ports) and select Power.
