@Cpaczek Looks Promising, I will give it a go in a few hours and post results here.

Hello People,
I am building a MagicMirror on Pi4. And since it has 2 hdmi out ports and I have a few monitors lying around, thought it will be a good idea to build a 3 feet x 2 feet mirror with two screens. Its in early phase right now as I am still configuring it. I am using two monitors in extended mode (not duplicating it).
How can I run magic mirror on both screens. I have created two instances of magicmirror in two folders, mm1 and mm2. I can run each of them successfully but they run on the same monitor only.
I need to run mm1 instance on monitor 1 and mm2 instance on monitor 2. Please guide. Thanks…

Great Build man, Specially the seamless hinge on the front.
