BP M1: HDMI output not working any more

0 237
Hello,

for a few days my BP is showing a strange behaviour now: HDMI output does not work any more if I use an HDMI cable , but if I use a HDMI to D-SUB (VGA) adapter, the video output works as expected. Rebooting won't fix it, and the monitor's HDMI input and the HDMI cable are working perfectly. The BP is running on Armbian, Version  20.11.6 Buster,  and all updates have been applied.

Have there been any changes to the firmware recently that could be the reason for this?
