How to make the background all black

@sdetweil thank you , I thought I was the only one facing that issue with the display. Thanks

@icripps This is because monitors use backlightning. You can use an OLED display instead if you want to build a crazy expensive mirror :)

But in daylight the backlight is hardly visible. As a simple workaround you can try to hang your mirror somewhere else where there’s more light.

@retroflex my TV/MM /Photoframe is a big nightlight in the hall…

I’m just cutting the power of the backlight with a relais and MMM-PIR-Sensor. This way the screen is really black and invisible while it’s up immediatly if the sensor detects motion.

@rabbit83ka How do you cut the power to the backlight only?
