Troubleshooting 

Before repair, check the following table to see if you can identify the cause of the fault. 

If the fault persists after you follow the instructions in the User Guide, you can consider repair. 

Fault Symptom 

Solution 

The power indicator does 
not light on. 

 

Check whether the power plug is securely connected to the socket. 
Check whether the power adapter supplies power properly. Ensure that 
the power adapter parameters meet the requirements of the LCD 
monitor. 

 

Check whether 

Power

 is set to

 Off

 in the menu. 

The power indicator 
lights on in orange. 

 

Check whether the signal cable is securely connected. 

 

Check whether the graphics card output resolution of the PC meets the 
optimal resolution required by the LCD monitor. 

 

Disconnect and then reconnect the signal cable, or restart the PC. 

The image is blurred, the 
screen displays 
interference stripes, or 
characters show 
prominent edge colors. 

 

Check whether wiring is secure. It is recommended that the connection 
cables delivered with the LCD monitor be used. Restart the PC. 

The image is abnormal. 

 

Check whether the output resolution of the graphics card is proper. 

 

Tap 

All Reset

  to restore all display parameters of the image to the 

default settings. 

The entire or part of the 
screen shows blurs 
(colored irregular thin 
stripes). 

 

This is due to mismatch between the PC's graphics card output format 
and that of the LCD monitor. Check the signal output format. 

 

Restart the PC. 

The image cannot be 
displayed in full screen 
mode, and the screen 
edge shows blurs. 

 

This is due to mismatch between the PC's graphics card output format 
and that of the LCD monitor. Check the signal output format. 

The monitor connected 
by the USB cable is not 
detected. 

 

Check whether the USB cable is properly connected. For details, see 
the "USB Connection" section. 

 

Use another USB port. Ensure that the PC and external equipment 
work properly. 

 

Restart the PC. 

 

Check whether the PC and operating system are compatible with USB. 
(To check the USB compatibility of each device, consult the 
manufacturer.) 

 

When the Windows operating system is used, check USB settings in 
the PC's BIOS settings.
