Black screen at boot up using DP, HDMI works?

I’m a new linux user and can’t figure out why when I boot my system using a Display Port there isn’t an output from my Nvidia card to my monitor, but when I boot the system using HDMI there’s no issues. If I boot using HDMI and then swtich to Display Port after logging in it works until I reboot. Can someone help me understand this and learn more about Linux as well as how to update video drivers (coming from windows I would just use NVCleanstall, but this is a completely different OS and I am willing to learn)
