      @lavolp3 I have 2 recycled 24 inch screens (easily found and easily for repair), and the big screen (46/50 inch) is more expensive :)

      @SammyJankins “If someone has the right config for the css”, it interests me too :)

          @Cbob you will have to run two instances of MagicMirror, and use the electron options to position the one instance on each screen.

          see here for another user positioning the MM screen on the right monitor

              following the configuration instructions

              https://github.com/MichMich/MagicMirror#general

              you can add a section for passing to the browser, electron
              add that line in front of the modules: line

              this says,
              not fullscreen
              800 pixels wide
              and starting (left edge is 0) at pixel 600

               electronOptions: {fullscreen:false, width:800, x:600},
              

              so, if your screen is 1920*2 wide
              to get the window onto the second screen,
              x:1920 seems right

                Guys, I’m having problem starting two instances of magic mirror.

                I have a Raspberry Pi 4. One HDMI port is connected on my PC Screen, the other one on my TV (just for example. I’ll use two screens on my actual mirror).

                I am able to start Magic Mirror on the second screen putting this line on the config.js of the second instance

                electronOptions: {fullscreen:true, x:1920},
                

                (My first screen is 1920px wide).

                I can get two instances to work, the problem is they are ALWAYS the same instance.

                One instance is installed on ~/MagicMirror. The second is on ~/MagicMirror2.
                I have two start scripts:

                ~/MagicMirror/mm.sh

                cd /home/pi/MagicMirror
                DISPLAY=:0 npm start
                

                And ~/MagicMirror2/mm2.sh

                cd /home/pi/MagicMirror2
                DISPLAY=:0 npm start
                

                The first instance I have my modules and the second is the default instance (default config.js) that comes with the instalation (except for the “electronOptions” above, “address” and “ipWhiteList”).

                The problem is that the second instance I start ALWAYS is the same as the first one.
                For example, if I use “pm2 start mm”, my first instance appears on my first screen.
                After that I use “pm2 start mm2” and also the FIRST INSTANCE appears on the second screen.

                Any thoughts on how to correct that? What am I doing wrong?

                        @banbutcher no, on PI4 there is only one ‘display’…
                        you have to use the electronOptions, x:??? value to set the left edge of each (0 is left)
