          @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?
