[Resolved] Can't mirror display

Hi me again.
I want to sync/mirror the (ryzen, ubuntu 23.10) display with a beamer 1920x1080. No idea how to sync it. Can’t get is synced. Everytime the internal display goes dark. Adapter are on the “right” place. HDMI or USB-C → HDMI both don’t work. Everytime I want to mirror the internal display goes dark.
Any idea how to mirror the framwork?

I can’t reduce the resolution of the internal display at all.

I installed the Kernel 6.6 and switched to Xorg. Works now.
