@Scavy SD card and raspberry pi4 are working perfectly, I tried using another sd card and same thing happened, I was thinking maybe is the way rasp imager burn the image, how many partitions I suppose to have? , thanks for the help!
@ian57 Hey, thank you for answering, this is my configuration:
It's the same as the one in that link but I used Notepad ++ to edit the config.txt instead of that SSH thing which I don't understand much, is that the problem?
