Monitor receives no signal

I have a problem with my current setup. At the beginning, once in a while when I boot my pc it wouldn’t show me any signal. Then I just manually restarted it ( sometimes restarting the monitor worked, other times the pc had to be restarted) if nothing worked and each time that solved the problem.

Now even if I plug in / out the DisplayPort cable, Switch the Monitor on/ Off and or restart the pc, nothing helps. Even though at the beginning of the bios it shows me that its receiving the signal. (Msi „Arsenal“ pops up. Then it switches to no signal.

The thing is my pc is completely turned on, and once i somehow get the thing working, the pc is on windows already, meaning that the pc booted completely normal, however something didn’t pick something up and I receive no signal. I also tried to hook it up to the tv via HDMI, but that didn’t seem to work either. I already ordered another DisplayPort cable, hoping that’s the issue (even though I don’t think it is because of the hdmi thing)

Does anybody know anything about this? It’s so frustrating.

I have 3900x. B450 tomahawk Max. Gigabyte 2080ti aorus elite (got a completely new one a few days ago)
