Monitor not displaying lower pixels

I don't really know how to frame the problem better but, i currently have only the upper 7-20 pixels on my monitor showing, but only during times where the OS is actively controlling tje display, while it works during bios, windows startup and the startup animation of the Monitor itself. As well as apparently some games like elden ring, dark souls 3 and sekiro, but not other games. Only thing those have in common, that would make sense to me is that they disable my cursor from exiting that screen onto a second one.

I would love to give you the model of the monitor, however the only way for me to do that is by seeing it on said monitor, as i had gotten it second hand. Only thing I have is that it's philips branded.

It occurred when i closed elden ring, don't know if that has anything to do with it tho.

It is connected to my graphics card via a display port cable.

If i need to disclose any other information i will be happy to do so, i just can't think of anythi g else useful right now.

Thank you for your help and time.

Edit: I have found out that this only occurs when my refresh rate is set to above 60hz, however reinstalling the driver or switching input cables doesn't seem to fix the problem.

Any help is appreciated
