I have to retest it with a fresh board. I updated to the firmware to the beta channel, but when I did this raspbian didn't show anything either. I also have hdmi_safe=1 disabled. Don't know if the update and config change was required or not because the truth is that the mini HDMI cable I'd used was broken. I had used it before with a Beaglebone Black and had the X output with rapbian on the Pi4, but after ordering a new cable, everything worked fine. -- B.Walter <bernd@bwct.de> https://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
