      While the description says it can drive both a VGA and HDMI connected monitors, resulting in a dual setup, MM is configured to launch one Electron screen. You might be able to run a side-by-side installation of MM and launch it on a secondary port, and I’m assuming it will launch a second Electron window that you will then have to position on screen. I just don’t know what will happen when/if you restart the rpi. Will it remember where the screens were positioned? only testing will answer that.

      A Life? Cool! Where can I download one of those from?

          The Raspi can’t manage two displays!

          2 display’s = 2 raspi’s!

            Do you really mean the Raspi, or do you mean MagicMirror?
            There is a VGA Modul for the Rasp, to handle two displays.

            It’s just interesting if MM knows hof to show it correct on restart.

              Hi jeff,

              the raspi has only a hdmi output and a output 4 a gpio display.

              It is not possible to really work with 2 display’s.

              U have a link to your VGA Module?

              If this module is really capable to run those 2 displays than u maybe can run a MM as web server build and one as MM2.

              If it’s possible to run two different MM2 instances i don’t really know that.

              Maybe it’s possible to run a second MM2 at another port!

                        So the VGA adapter works (despite ugly soldering) but i did not manage to use VGA and HDMI simultaneously. After some further research on the topic i think it is necessary to use a custom kernel.

                        On ubuntu i know you can configure dual display using xrandr, but i have no idea how to do something like that with raspbian.

                        Please see this very interesting question at stackexchange: http://raspberrypi.stackexchange.com/a/27048/55885.

                        I will try to dig a little deeper but to be honest i’m not deep enough into linux and development to fully understand this issue.
                        If you have any advice or interesting links on how to get dual display to work, please share!
