Using a pi3, has been running ok for 6 months, screen went black, thought it was cable cause I’m using a vga to hdmi connector, but I’ve tried different screen and just a hdmi cable. What’s confusing is that the mirror is still working as I’m using the remote module and I can view it on my laptop, the screen is ok cause it’s going through the boot , just when desktop shows it’s goes off

Sounds like you have some great ideas! Perhaps a module that according to date will do different things… perhaps via sensor as well? Right now I"m on what I call my Frankenstein mirror… LOL It’s an x86 board just hanging here…planning on a 32" version that I would like to be powered up!! To handle the voice stuff better :)
