Memory effect with MM2

[lolobyte]

Hello girls and boy’s.

I’m worry about a memory effect problem with the static text om my screen with MagicMirror.

Can somebody explain us if my concern is right or is there no problem with this kind of permanent static text presentation.

It depends on the displaytechnology you are using. Generally you are right about that. But it is not that bad. https://en.wikipedia.org/wiki/Screen_burn-in

Anyway my idea (the basic idea is very old, currently google is using something in android wear) is a module, with a Screen-burn-in protection that periodically shift the contents of the screen by a few pixels :)

MMM-Anti-screen-burn-in ? :P

@schlachtkreuzer6 you could create a class and add this to the body where the margin is different than the basic 60px and toggle the class to the body every 6 hours or so

@schlachtkreuzer6

MMM-Anti-Screen-Burn-In.css

.MMM-Anti-Screen-Burn-In {
    margin: 55px 55px 65px 65px; /*this would shift it 5 pixels higher and 5 pixels to the right side than the standard of 60px on each side*/
}

MMM-Anti-Screen-Burn-In.js

start: function(){
    setInterval(() => {
        document.querySelector("body").classList.toggle("MMM-Anti-Screen-Burn-In");
    }, 6 * 60 * 60 * 1000); // every 6 hours
},

getStyles: function(){
    return ["MMM-Anti-Screen-Burn-In.css"];
}
