Has anyone seen anything about the solution to this yet? Had a proper man-look 
can’t see anything…
The only thing i see so far is downgrading or the unplug the hdmi then plug it back in after post… but no real fix
That is what I thought. Don’t like holding packages back, can be dangerous 
I agree. I’m hoping Nvidia releases a new driver this week but I might pick up a DP cable to hdmi and see if it solves at least some of the issue. If I can upgrade but have to use a DP cable i’d be okay with that.
Just an update… Nvidia acknowledged the issue and able to reproduce it. Hopefully they can fix it soon.

has any tested nvidia-… 520.56.06-1 just available? any issues?
Working for me on Plasma X11 and Wayland, glitchy on Sway (so no change!).
The new nvidia driver fixed my black screen issue. 12900k with a 3090.
