      Habe einen Pi2Scart und nach der Installation von Recalbox die config.txt editiert. Leider bekomme ich kein Bild. Es gibt eine auf Recalbox basierende Distribution namens RGB-Pi damit bekomme ich ein Bild, allerdings sind die Farben komplett fehlerhaft und man kann nur mit Mühe und not irgendwas erkennen.

      Leider bin ich mit den dt Parametern und HDMI Timings absolut gar nicht vertraut. Vermutlich wird da mein Fehler sein.

      disable_audio_dither=1
      dtparam=audio=on
      dtoverlay=vga666
      enable_dpi_lcd=1
      display_default_lcd=1
      dpi_group=2
      dpi_mode=87
      hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1

      Funktionierte nicht. Habe folgendes Tutorial befolgt:
      http://retrorgb.com/rpi240p.html

      Kann mir da irgendwer weiterhelfen?

        @funkybunch hast du eine abgeänderte version von recalbox? Odr die originale Software?
        Evtl. kann dir das weiterhelfen? https://github.com/recalbox/recalbox-os/wiki/Video-configuration-detailled-(EN)

          Aktuell habe ich wieder die original stable 4.0.1 drauf.

          Leider hilft mir das Wiki wenig weiter, weil mehr auf HDMI eingegangen wird. Ich nutze aktuell einen Adapter, für einen RGB Output über den GPIO, damit ich wirklich möglichst alles an Bildqualität rausholen kann. Benötige ein 15khz Signal (240p)

            @funkybunch okay, lass uns mal @Substring fragen 🙂

            @Substring He uses a "RGB output" connnected to GPIO (see link in first post) Does this work somehow in recalbox?

              Das ist übrigens das Interfaceboard für den Scartanschluss.

              Und hier die genauen Infos.

                    @Substring Hi. I tried diffferent options last night. But with the Recalbox image i get no picture (i only hear sound after booting). With retropie or other distributions it works. the same settings in Recalbox won't. So i copied the settings from RGB-Pi (which works also) and copied it to my boot partition. but i get the same problem. i've commented the force hdmi output and tried to set to zero, but without success. 😞
                    I can not even see the noobs screen

                      @substring : Smallcab will perhaps lend me a Pi2scart module to make the support for recalbox. When arrived I will make some tests and write a mini howto for this module.

                        @funkybunch please paste your config.txt. I guess it's an overlay problem

                          @Substring i made the additional entry's from my starting post at the end of the config text on boot partition. disable "force hdmi" did not help.
                          I can post my complete config tonight.

                            @funkybunch I'm pretty sure it's an overlay problem. Does the vga666.dtb(o) exist in /boot/overlays ?

                                  @funkybunch I've already been told about the dpi24 overlay not working with recalboxfs ... I guess this could just be because of our "old" kernel, but can't tell for sure

                                  But remove the #240p from your hdmi_timings line. Also just try usual CEA/DMT mode that should fit your monitor (but write dpi_mode and dpi_group instead of hdmi_mode and hdmi_group)

                                        Yes 😉 i'm pretty shure i tried this way yesterday without success but i'll try it later again.

                                          @Substring now i made the update to 4.1 unstable before i change the settings for using with a CRT. Now it Works! i have to set the overscan correctly, but that's not a big deal. 🙂 When i finished, i can post the final config.txt

                                            @funkybunch i'm not sure overscan will have the desired effect (something i must try), but porchs should do it
