Thank you @philippower2 for reopening the thread.
Updates so far:
[ul]
[li]speccy link: http://speccy.piriform.com/results/8...SAuYLWTKoLb5Kd [/li][li]I have booted from a USB stick (Ubuntu) and the display worked without any issues (which I think excludes any hardware issues)[/li][li]tried Windows Recovery based on a replay from another topic - restored to the version from 22.12.2022 - no changes, had no effect at all[/li][/ul]

Another interesting update. I launched OBS, and from OBS I saw there the second the signal is going to the 2nd display, meaning in the OBS preview I can see the windows opening up, and I can drag a window to the extended monitor. But, like before, the actual display is black.

might sound stupid
when plugged in use the menu buttons on the monitor to force input hdmi

I have three options there: VGA, display port, HDMI.
Just for the sake of trying everything I have tried all options. Sadly none of them work. I get “No signal” on all of them.
