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?

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.
