        Then start with the default RetroPie Pi4 image and add again the lines neded by the display, omitting the advice from their document about the dtoverlay = vc4-fkms-v3d.

          Uh Nope that didnt work.
          In fact a rewrote the image after properly erasing everything, and launching it for the first time still showed that error.
          i didnt edit anything at all.
          It didnt do that before.
          What can i do now?

            Can you post the current config.txt ? The previous one had some obvious errors (hdmi_cvt is a command, the dtoverlay=ads784... should be just one line and not several). If it's the same as before, there's no need to post again.

              it was working before. I dont know why its having an issue now

              could it be something with the SD card causing an error?

                @Fingerprint said in RPI 4 Elecrow 5 inch screen error (help):

                could it be something with the SD card causing an error?

                I doubt it. The resolution you added is not correct. hdmi_group=1 and hdmi_mode=1 is CEA (TV) at 640x480.

                You'll need a custom HDMI mode, since the resolution is non standard: Try something like:

                hdmi_group=2
hdmi_mode=87
hdmi_ignore_edid=0xa5000080
hdmi_cvt=800 480 60 6 0 0 0

                    Are you sure you're using the Pi4 image ? The error message

                    *failed to add service - already in use?

                    it's displayed by the old RPI GPU drivers, which are used by the Pi3 and below, but are not supported or used by the Pi4.

                      I mean when I downloaded the image from this site it said the file was Retropie 4.8
                      I'll redownload the image again.
