Hi folks,
I just tried to use a spare notebook screen as display for a magic mirror. Unfortunately the “black” of the screen is not really “black” as it is to bright. Therefore the display is visible behind the mirror. Do you know some tricks to fix/reduce this problem? Not sure if there is feature to reduce the brightness of the magic mirror app? (The display is already on lowest brightness)
I wonder if a display foil could help?

Best regards
