Screens black is to bright
-
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

@alex1223 - If you’ve already adjusted the monitor brightness to it’s lowest level then you’ve got a problem. You may be able to adjust the contrast to increase it. That should make the gray/white pop a bit more, but if you’re seeing the back light then it won’t help all that much.
Unfortunately, the only solution I can think of is to replace your mirror glass with a variant that lets in less light. You can purchase samples of different one way glass recipes and hold them up to the monitor to find one that reflects enough light that the back light isn’t visible. It will limit how bright the white is, of course.
