Update 13.2.1 External Monitor detected but goes into standby

I just updated to Ventura 13.2.1 and my external monitor, an ultrawide Lenovo P40w-20, is detected but goes into standby mode.

What is weird is that the OS acts as if the monitor is connected, since I can move the mouse to it, but the monitor itself is on standby.

I tried the multiple suggestions I found online but nothing worked.

Any ideas? Apple please fix this ASAP, I need the monitor to work!

I am on a Macbook Pro 14 M1.
