I just bought a new gaming monitor and when I start my pc (plugged in via DisplayPort) I get signal for a moment and can enter bios, however, I just get “DisplayPort no signal” afterwards. I tried connecting the monitor to my friend’s pc (using the same cable) and it worked completely fine. So then I plugged my pc into an old monitor using the same DisplayPort cable (to check if my pc/gpu was the issue) and it also worked fine. I am now completely lost. I have absolutely no idea what to do. If anyone has any suggestions please let me know.
