      @duiz Did you plugged when the pi was turned on and the tv too? sometimes you first have to connect the hdmi cable and then turn on the devices

        @chicuelo No it was turned off and unplugged from the socket (using the pi official power outlet) so it was completely powered off before plugged in and powered on again. I've tried another TV and same result.

        This is my config.txt

          You have all the hdmi_ options commented, so there's no configuration here. Remove the # to un-comment the configuration option:

          hdmi_group=1
hdmi_mode=16

          and remove your overclock when testing.

          If that doesn't work, try with hdmi_safe=1.

            I got things to show up, but it has 2 issues now.

            1. there is no audio out of the tv

            2. the screen seems to be outputting a 720p window within a 1080p frame. So the pi is outputting 1080, but the information is inside the 720 frame.

              @duiz ate you using the first HDMI port - next to the usb c power input? You need to use that port for sound.

                @BuZz I am using the one that is almost right underneath the usb-c power port, is that the right one?

                  @duiz It's not quite underneath, it's on the 1st HDMI port right of the USB-C port. Did you configure your audio to go through the HDMI port using the Audio menu in RetroPie ?

                      @duiz that case changes the port positions. Maybe try the other port if you still can't get audio working.

                        @BuZz I'll give it a try. Do you have any idea about the other issue? (1080 output with a 720 frame within it.

                          @duiz turn off overscan in raspi-config.

                            @BuZz Tried to uncomment the overscan but it still outputs into a 720 window on a 1080 output. Is it just a case of the software being too early still and exhibiting bugs with 1080p displays perhaps?

                            For reference, this is what I am working with now as we are testing it

                            # For more options and information see

[all]
#dtoverlay=vc4-fkms-v3d
overscan_scale=1

                            No audio out of either HDMI port, black display on one TV but not the other. 1080p display but framed 720 output.

                              tengo el mismo problema pero con la diferencia que si tengo imagen y sonido, pero cuando estoy jugando la pantalla se pone negra y la señal vuelve sola, probe varias configuraciones y cables HDMI, sin suerte

                                @duiz Here is my idea for fixing your resolution problem.

                                Firstly, try this.

                                Change this:

                                #disable_overscan=1

                                To this:
                                disable_overscan=1

                                Reset and see if that fixes it.

                                If that doesn't work change this :
                                #framebuffer_width=1280
                                #framebuffer_height=720

                                To this :
                                framebuffer_width=1920
                                framebuffer_height=1080

                                Make sure to remove the # before those lines.

                                If it doesn't work be sure to put it back the way it was.

                                Hopefully one of those ideas helps.
