      @Substring ok, so I'm unable to actually modify the xinitrc file as it's read only (no surprises there).
      I tried following the instructions here
      https://github.com/recalbox/recalbox-os/wiki/Change-display-resolution-on-x86---x86_64
      but I kept getting "read only system file" message when copying the file to a different directory.

      I then modified the file on my local machine but again, when I try to copy the modified file back to the xinitrc directory I get a read only error on the directory.

      I tried to chmod the xinitrc directory but that didn't work.
      I tried to chmod the file but that also didn't work.
      I tried to change user to sudo but sudo isn't a recognised command.
      I tried to use su instead but when I enable su with su - I wasn't prompted for a password so su didn't work.

      I am logged in as the root user as outlined here so I'm not sure what else I could do to actually modify this file.

      Any help would be great. 🙂

        Just thinking there. Is the reason that I cannot modify the file is because it is currently in use?

        Is there a command I can run to say stop a service that might be using the xinitrc file so I can modify it?

          but I kept getting "read only system file" message when copying the file to a different directory.

          Just to note that I was actually able to see the .xinitrc file in the /recalbox/share/system directory after trying a second time. Not sure what happened first time around, possibly missed something when copying the command initially.

          Anyway, I was able to modify the file there and added the following parameter
          xrandr --output HDMI-0 --mode 1920x1080 --same-as LVDS-0

          Once I rebooted Recalbox the issue still persisted. Not sure what else to do at this point.

            @qoobit it's still better to quit ES first with /etc/init.d/S31emulationstation stop

            Then to edit the file out of the user's home path, you need to mount -o remount, rw /

              @substring, thanks very much. I was able to write to xinitrc in the /X11/xinit directory after stopping ES.
              Now that I am able to start and stop the service freely it's a lot quicker to verify if the changes made to xinitrc actually work. Unless I should be doing a full reboot after making those changes?

              So far though, I haven't had any luck. Behaviour is still this same.
              I stripped back the xrandr attributes to just output as HDMI now in case there is some issue with outputting to both the netbook and the tv.
              Not sure if it's an issue trying to output HD to a 4k tv but I would have just assumed the image would be smaller.

              If you have any other suggestions that would be great. If not, I appreciate the help anyway.
              Cheers!

                    Have you tried switching off the laptops display and only displaying via HDMI ?

                    xrandr --output LVDS-0 --off --output HDMI-0 --mode 1920x1080

                      As i was pleasured last night, today i got the behaviour that Xorg-server doubled the viewport of LVDS1 (laptop screen) --same-as VGA1 (external monitor): scratch! - external Monitor spots the RecalBox menu and Kodi only in a 1280X800 view upper left inside a 1920x1080 view.

                      By your help i fond the xinitrc and wrote:
                      # xrandr --output output_name --off
                      DISPLAY=:0
                      xrandr --listmonitors | grep VGA1 && {
                      xrandr --output LVDS1 --off
                      xrandr --output VGA1 --mode 1920x1080
                      }

                      out of that.

                        Thanks to all the thread I was able to do it
                        My machine is a laptop and was connected to a second screen via display port
                        So I have not modified the .xinicrt since I didn't find it but I manually ran the following

                        DISPLAY=:0 xrandr --listmonitors
                        Then I had two connected monitors
                        eDP-1
                        And DP-1
                        So I did DISPLAY=:0 xrandr --output eDP1 --off
                        And the laptop screen went black
                        After that I did DISPLAY=:0 xrandr --output DP-1 primary
                        And then I clicked escape on the laptop and I was back in the main screen displayed on the tv

                        Thank you so much for your investigation and output
