Hi everyone

I'm here looking for something to solve a pretty annoying issue:
I have connected my laptop via HDMI to a secondary monitor, which I set up as my favourite
When I boot my system and log in, the KDE loading windw appears on both the monitors:
on the laptop one it stays there until the boot is complete, on the secondary montior the screen goes black
and when the log in in completed it starts glitching (only this montior)

to solve this I have to deactivate the monitor, and then, re-activate it from the display settings.

Anyone knows how to fix this?

Operating System: EndeavourOS
KDE Plasma Version: 5.24.3
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.3
Kernel Version: 5.16.13-arch1-1 (64-bit)
Graphics Platform: X11
