@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

thank you for your answer, but I did not succeed.
I have two instances that launch, but it appears on the same screen. Are you solution for to help me ?

@Cbob
following the configuration instructionshttps://github.com/MichMich/MagicMirror#general
you can add a section for passing to the browser, electron
add that line in front of the modules: linethis says,
not fullscreen
800 pixels wide
and starting (left edge is 0) at pixel 600electronOptions: {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?
-
@Bruno use pm2 info mm, and pm2 mm2 to make sure they are starting the right script

Ok, sorry. Just found out… I was using the same port on both instances :neutral_face:
-
-
@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) -
i knew i could be wrong!! :D
