New install keeping Display Port monitor shut off?

Hi, recently reinstalled my system and decided to go with the default XFCE install.
Everything was going well(apart from not properly remembering which monitor is which and their wallpapers[?]) but after a system update with yay xfce no longer… properly turns on my DP monitor?
I can see that the backlight is shut off and not even the settings menu of the monitor comes up so its hard shut off, and occasionally it flickers back on for a split millisecond, more frequently if set to 144hz refresh rate weirdly enough, does anyone know what’s causing this?
it only happens once xfce starts up, on the login screen or in plasma, installed afterwards to check, it works just “fine”
