keithr Posted Saturday at 11:02 PM Share Posted Saturday at 11:02 PM I set up a new Banana Pi M4 Zero, with an HDMI monitor that had previously been used with a Raspberry Pi, a USB hub with a keyboard and mouse. I downloaded the Armbian Ubuntu Jammy desktop, the activity light flashed a bit but no video. I soldered a header to the debug serial pads and connected to a PC through a serial to USB converter. Using that link I could see the boot process, and communicate. I used armbian-config to set up wifi etc, but still no video. I have tried Jammy minimum, and both Debian downloads but still no video. There appears to be nothing coming across the HDMI connection, the monitor detects that there is a physical connection but no video. The same thing with a second monitor. Looking at the u-boot environment, it shows console=both, disp_mode = 1080p60, fb0_width= 1920,fb0_height= 1080 all of which are within the capabilities of the monitors, but still no video. Am I missing a driver or something? 0 Quote Link to comment Share on other sites More sharing options...
