    Hi Arima,

    Thanks for your post.  The phenomenon you are seeing appears to be image burn-in.  This can occur when a static message is shown on the display for a long period of time.  Unfortunately, there is not a way to reverse the effect of image burn-in.

    We recommend the following practices to prevent image burn-in from occurring:

    • Power off the display when not in use
    • Use a screensaver
    • Use a scrolling text to prevent the message from staying in the same position
    • Lower the screen brightness or contrast

    Please refer to our blog post and YouTube video below for additional information:
