My monitor isn't working during boot anymore

I’m traveling with a portable monitor connected to a 6800xt over USBC and everything has been working fine with it until updating a few days ago.

I updated manjaro packages and then the kernel to 5.15, and somehow that resulted in my monitor not working during boot anymore. Which I just don’t understand the logistics of AT ALL. How does the host OS relate to video out during boot?

The video out also didn’t work once booted into linux but I was able to resolve this by replugging the monitor a couple of times after each restart. Ultimately reverting back to the 5.14 kernel fixed it in Linux but didn’t fix it during boot.

So now I just have to enter my LUKS pass blindly and hope for the best or that I never need to adjust my bios settings ever again?
