This image has successfully updated my RPi4, there is a picture, everything is fine. I use 1080p resolution
on 9.2.4 (RPi4) the picture disappeared, while there is sound and hdmi cec works fine, I hear how the system reacts to pressing the remote control key, but I see nothing. The TV itself thinks that it is being given a signal, writes that it is there and writes the resolution, but the picture is just black. Changing the hdmi port doesn't help. This also happens when upgrading from 9.2.3 and during a clean install.
