Raspberry Pi 3B+ AIPTEK Mobile Beamer

    Hello,

    I am trying to use my old iPhone/iPad mobile beamer AIPTEK "PocketCinema T30" with my Raspberry Pi 3B+ and Libreelec.


    I connect the beamer with the analog "out" of the rasp and the "in" of the beamer. I use two "headphone jack" to chinch adapter to check if the signal is switched between the audio and the video composite.


    - Change the resolution in Kodi doesn't work


    Do I have to set the boot thingy file to ignore the hdmi (even it is not pluged in?)


    Does anybody manage to get this to work? I would love to use the old beamer instead of buying a new one


    Thank you for your help




    thank you for your answer. I connect hdmi set 640x480p in Kodi and restart disconnect the hdmi and plugin the analoge plug...but didn't show anything
