Ok, I got my tablet, the small test mirror glasses and also MM installed on windows. the display is viewable through all the glasses, but through 3 of them only pretty weak. the fourth one lets much more light through, but i also can see the edges of the display, because it’s not that much of a deep black. in my mind i want a really sophisticated solution. so i will go with the lower light glass or maybe a thin white border around the display background, so it looks like a frame…

when i turn off the display, the tablet locks it, so i definitely need a login solution.

idea: display general data on the windows lock screen for everyone. display personal data when logged in.
