Problem is worse with kernel 5.15.0-22, while in distros providing 5.16.11+ and 5.17 kernels the problem is gone. Now in 5.15.0-22, no video ever shows up after the Grub selection is made. The PC apparently hard locks immediately with black screen when two displays are connected, even when only one is powered on.
