@cowboysdude the thing is I already have a large hallway mirror someone gave me, so I thought I could add a couple of monitors behind it and make a nice magic mirror.

@lpassamonte not sure if you’re even still here or trying this but I just joined so gonna necro the thread.

Probably better for you to post rpi specific questions in the raspberry pi forums, and a quick google search found this thread that might solve your issue: https://www.raspberrypi.org/forums/viewtopic.php?t=5107

Basically they had to edit the config file and enable a couple of HDMI boot options. Good luck!

I’m wondering if I can take an old glass mirror and scrape off some of the backing and replace that area with the stick-on stuff so that I can make the size exactly to the dimensions of an old smart TV screen I have? What are the potential gotchas of doing this?
